                      AUGUST CLIMATE HIGHLIGHTS

A PERSISTENT UPPER TROUGH BROUGHT A FIFTH MONTH IN A ROW OF COOLER 
THAN NORMAL WEATHER TO UPPER MICHIGAN IN AUGUST 2004 AS A NORTHWEST 
FLOW ALOFT DROVE NUMEROUS CANADIAN COLD FRONTS THROUGH THE UPPER 
GREAT LAKES. JUST LIKE IN JULY...THERE WAS A LACK OF REAL SUMMER 
HEAT AND NO 90-DEGREE TEMPERATURES REPORTED. AUGUST TEMPERATURES 
AVERAGED THREE TO SIX DEGREES BELOW NORMAL AT MOST PLACES...AND THIS 
MONTH PLACED IN THE TOP TEN COOLEST OF EIGHTH MONTHS AT ALMOST ALL 
REPORTING STATIONS. MUNISING LOGGED A MONTHLY TEMPERATURE DEPARTURE 
OF -6.2 DEGREES AND THE SECOND COOLEST AUGUST ON RECORD. ONLY AUGUST 
IN 1950 WAS COOLER AT MUNISING THAN IN 2004 (MEAN TEMPERATURE 57.6 
DEGREES VERSUS 58.7 IN 2004). AT IRONWOOD...WHERE RECORDS DATE BACK 
TO 1901...AUGUST 2004 (58.6 DEGREES) WAS THE THIRD COOLEST IN THE 
LAST 103 YEARS...TRAILING ONLY 1977 (56.5) AND 1907 (58.5) FOR FIRST 
PLACE AS THE COOLEST AUGUST IN OVER A CENTURY. DESPITE FAIRLY 
ABUNDANT AUGUST PRECIPITATION THAT MINIMIZED FIRE DANGER AND 
MAINTAINED FAVORABLE SOIL MOISTURE FOR LUSH PLANT GROWTH...CROPS 
LIKE TOMATOES THAT THRIVE ON WARMER WEATHER FARED POORLY DURING 
SUMMER 2004 BECAUSE OF THIS AUGUST (AND JULY) CHILL.

ALTHOUGH THE NORTHWEST FLOW ALOFT TENDED TO KEEP STRONGER LOW 
PRESSURE SYSTEMS AND MORE SUBSTANTIAL GULF OF MEXICO MOISTURE FROM 
INVADING THE UPPER GREAT LAKES AND INTERACTING WITH THE NUMEROUS 
COLD FRONTAL PASSAGES...PRECIPITATION OPPORTUNITIES WERE FAIRLY 
FREQUENT. SO MONTHLY RAINFALL WAS NORMAL TO ABOVE NORMAL FOR THE 
MOST PART. FAR WESTERN UPPER MICHIGAN WAS PARTICULARLY WET BECAUSE 
THESE COUNTIES WERE IN A FAVORABLE LOCATION RELATIVE TO THE TRACK OF 
UPPER AIR DISTURBANCES WHEN THE TROUGH DEEPENED AROUND 8/10 AND WHEN 
A STRONGER SOUTHWEST FLOW ALOFT ADVECTED MORE SUMMER-LIKE MOISTURE 
INTO THE UPPER GREAT LAKES AROUND 8/25. IN FACT...A SWATH FROM 
IRONWOOD THROUGH ONTONAGON COUNTY AND INTO THE KEWEENAW PENINSULA 
AND BARAGA COUNTY PICKED UP 5 TO 7 INCHES OF RAIN IN AUGUST...ABOUT 
150 TO 200 PERCENT OF NORMAL. BARAGA WAS THE WET SPOT WITH 6.71 
INCHES TOTAL AUGUST RAINFALL...BUOYED BY A 3.88-INCH DOWNPOUR DURING 
THE OVERNIGHT ON 8/25-8/26. THERE WAS ANOTHER AXIS OF HEAVIER RAIN 
AROUND MUNISING IN ALGER COUNTY. IN FACT... MUNISING EXPERIENCED ITS 
FIFTH WETTEST AUGUST WITH 4.95 INCHES OF RAIN (ABOUT 150 PERCENT OF 
NORMAL). THE ONLY AREAS THAT RECEIVED SUBSTANTIALLY LESS 
PRECIPITATION THAN NORMAL WERE ACROSS THE FAR SOUTH NEAR MENOMINEE 
AND CENTERED AROUND IRON COUNTY...WHICH JUST MISSED THE HEAVIER 
RAINS THAT HIT THE FAR WEST AROUND 8/25. STAMBAUGH IN IRON COUNTY 
AND MENOMINEE MEASURED ONLY 1.83 INCHES AND 1.74 INCHES 
RESPECTIVELY...ABOUT 50 PERCENT OF USUAL AUGUST RAINFALL.

ALTHOUGH AUGUST STARTED ON A WARM NOTE WITH DAILY TEMPERATURES 
AVERAGING 5 DEGREES ABOVE NORMAL ON 8/1 AND 8/2...A POTENT COLD 
FRONT THAT TRACKED ACROSS THE U.P. LATE ON 8/2 ADVECTED A COOLER 
AIRMASS INTO THE UPPER GREAT LAKES ON 8/3. THIS FRONT SERVED AS A 
FOCAL POINT FOR THUNDERSTORM DEVELOPMENT ACROSS MAINLY SOUTH CENTRAL 
AND EASTERN UPPER MICHIGAN ON 8/2...AND SOME OF THE STORMS IN DELTA 
AND SCHOOLCRAFT COUNTY BECAME SEVERE AND PRODUCED TORRENTIAL 
DOWNPOURS. GLADSTONE IN DELTA COUNTY WAS DELUGED BY 3.30 INCHES OF 
RAIN. THIS HEAVY RAIN CAUSED SOME FLOODING...WHICH CLOSED PORTIONS 
OF M-35. LARGE HAIL AND DAMAGING WINDS WERE NOTED AS WELL ACROSS 
PORTIONS OF DELTA AND SCHOOLCRAFT COUNTIES. TEMPERATURES DURING THE 
PERIOD 8/4-8/7 AVERAGED ABOUT 5 DEGREES BELOW NORMAL AS DRY CANADIAN 
HIGH PRESSURE DOMINATED AND BROUGHT SOME DELIGHTFUL MID-SUMMER 
WEATHER TO THE AREA. OVERNIGHT LOWS FELL INTO THE 30S AT SOME OF THE 
COOLER INLAND LOCATIONS...INCLUDING A FROSTY 33-DEGREE READING AT 
WATERSMEET IN GOGEBIC COUNTY AT DAWN ON 8/5.

THERE WAS A BRIEF WARMUP ON 8/8 AND 8/9 AS THE UPPER TROUGH DEEPENED 
JUST TO THE WEST...INCREASING THE SOUTHWEST FLOW OF WARMER AND 
MOISTER AIR INTO THE UPPER LAKES. THE INTERACTION OF THIS MORE HUMID 
AND UNSTABLE FLOW AND THE NEXT IN THE SERIES OF STRONG COLD FRONTS 
WAS MORE THAN ENOUGH TO TRIGGER NUMEROUS SHOWERS AND THUNDERSTORMS 
ON 8/8 AND 8/9. SOME OF THE HEAVIER SHOWERS PRODUCED HEAVY RAIN... 
INCLUDING 1.06 INCHES AT MUNISING ON 8/8 AND AS MUCH AS 1.25 INCH AT 
PELKIE ON THE BARAGA-HOUGHTON COUNTY LINE ON 8/9. SOME OF THE STORMS 
ALSO BECAME SEVERE ON 8/9 EAST OF IRON MOUNTAIN AND MARQUETTE... 
DROPPING LARGE HAIL AND/OR CAUSING DAMAGING WINDS IN MENOMINEE... 
MARQUETTE...AND DELTA COUNTIES. HAIL AS LARGE AS GOLFBALLS FELL JUST 
SOUTH OF HARVEY IN MARQUETTE COUNTY UNDER THE MOST INTENSE 
THUNDERSTORM. VERY COOL AIR FOLLOWED THIS FRONT INTO THE UPPER GREAT 
LAKES ON 8/10-8/14...WHEN DAILY TEMPERATURES AVERAGED 10 DEGREES 
BELOW THE MEAN. A STRONG UPPER AIR DISTURBANCE BROUGHT SOME HEAVY 
RAIN TO WESTERN UPPER MICHIGAN ON 8/10-8/11...INCLUDING 2.20 INCHES 
AT ATLANTIC MINE IN HOUGHTON COUNTY...2.00 INCHES AT PHOENIX IN 
KEWEENAW COUNTY...1.48 INCHES AT IRONWOOD...1.40 INCHES AT BIG BAY 
IN MARQUETTE COUNTY... AND 1.37 INCHES AT BRUCE CROSSING IN 
ONTONAGON COUNTY. RAINFALL AMOUNTS FELL OFF SHARPLY TO THE EAST. THE 
COMBINATION OF THE CLOUDS...RAINFALL...AND COOLER AIR RESULTED IN 
UNSEASONABLY LOW MAXIMUM TEMPERATURES ON 8/10 AND 8/11...READINGS 
MORE TYPICAL OF MID-APRIL OR MID-OCTOBER. THE 51-DEGREE HIGH AT 
IRONWOOD ON 8/10 SMASHED THE PREVIOUS RECORD LOW MAXIMUM TEMPERATURE 
OF 59 FOR THE DATE THAT HAD STOOD SINCE 1903. FOR THE SECOND DAY IN 
A ROW...IRONWOOD ON 8/11 SAW ITS PREVIOUS RECORD LOW MAXIMUM 
TEMPERATURE DEMOLISHED...WITH THE 49-DEGREE HIGH EASILY ECLIPSING 
THE STANDARD OF 55 LOGGED ON 8/11/1964. THE MARQUETTE NWS RECORDED A 
HIGH OF 52...ALMOST 10 DEGREES LOWER THAN THE PREVIOUS RECORD LOW 
MAXIMUM OF 60 OBSERVED ON 8/11/1992. ONCE SKIES CLEARED WITH THE 
ARRIVAL OF THE CANADIAN HIGH PRESSURE CENTER ON 8/12...OVERNIGHT 
LOWS ON 8/13... 8/14 AND 8/15 BOTTOMED OUT IN THE 30S AT THE COOLER 
INLAND PLACES. THE MERCURY REACHED AS LOW AS 31 AT WATERSMEET ON 
8/13...31 AT CHAMPION IN MARQUETTE COUNTY ON 8/14...AND 35 AT 
CHAMPION ON 8/15.

TEMPERATURES RECOVERED TO NEAR NORMAL ON 8/15 THROUGH 8/18. BUT THE 
PASSAGE OF ANOTHER STRONG COLD FRONT DELIVERED THE NEXT PUNCH OF 
COOL CANADIAN AIR. THERE WERE THUNDERSTORMS IN ADVANCE OF THIS FRONT 
ON 8/18...INCLUDING ONE THAT DELUGED DAGGETT IN MENOMINEE COUNTY 
WITH 0.91 INCH OF RAIN IN JUST 15 MINUTES. ANOTHER THUNDERSTORM IN 
MENOMINEE COUNTY PRODUCED WIND GUSTS IN EXCESS OF 60 MPH AND FELLED 
LARGE TREES NEAR STEPHENSON. STRONG NORTHWEST WINDS BEHIND THE FRONT 
APPROACHED 60 MPH OVER THE KEWEENAW PENINSULA...RESULTING IN DOWNED 
TREES AND POWER OUTAGES OVER THE KEWEENAW. COOL WEATHER WAS THEN THE 
RULE FROM 8/19 THROUGH 8/23. DAILY TEMPERATURES DURING THIS 5-DAY 
PERIOD AVERAGED CLOSE TO 10 DEGREES BELOW NORMAL. THERE WERE MORE 
LOWS IN THE 30S DURING THIS TIME AWAY FROM THE WARMER LAKESHORES... 
INCLUDING 33 AT CHAMPION ON 8/19...36 AT CHAMPION ON 8/20...AND 34 
NEAR IRON MOUNTAIN ON 8/21. SINCE THIS AIRMASS WAS DRIER THAN THE 
ONE WHICH BROUGHT THE COOL PERIOD ON 8/10-8/14...THERE WAS MORE 
SUNSHINE AND NO RECORD LOW MAXIMUM TEMPERATURES.

THE UPPER AIR PATTERN UNDERWENT A MAJOR CHANGE ON 8/24 TO ONE THAT 
FEATURED AN UPPER RIDGE IN THE EASTERN U.S. AND THE GREAT LAKES. FOR 
THE FIRST TIME IN AUGUST...DAILY TEMPERATURES AVERAGED WELL ABOVE 
NORMAL 8/25-8/27...AS MUCH AS 10 DEGREES ABOVE THE MEAN. A FRONTAL 
BOUNDARY ON THE NORTHERN EDGE OF THE BUILDING WARM AIR MASS REMAINED 
NOT FAR FROM THE U.P. ON 8/24-8/27 AND SERVED AS THE FOCUS FOR 
NUMEROUS SHOWERS AND THUNDERSTORMS AS THIS FRONT INTERACTED WITH 
INCREASINGLY MOIST AND UNSTABLE AIR. THE FIRST ROUND OF HEAVY RAIN 
FELL OVER THE EASTERN TWO-THIRDS OF UPPER MICHIGAN AND WAS 
COINCIDENT WITH THE PASSAGE OF A WARM FRONT DURING THE OVERNIGHT ON 
8/24-8/25. AS MUCH AS 1.57 INCHES FELL AT COOKS IN SCHOOLCRAFT 
COUNTY AND 1.53 INCHES AT THE MARQUETTE NWS. ANOTHER ROUND OF 
WIDESPREAD HEAVY SHOWERS STRUCK FAR WESTERN UPPER MICHIGAN ON 8/25- 
8/26. RAINFALL FROM IRONWOOD TO BARAGA BECAME EXCESSIVE IN SOME 
AREAS...WITH UP TO 5 INCHES FALLING NEAR BOB LAKE IN HOUGHTON 
COUNTY...3.88 INCHES AT BARAGA...2.25 INCHES AT PELKIE NEAR THE 
BARAGA-HOUGHTON COUNTY LINE...1.60 INCHES AT IRONWOOD AND 1.52 
INCHES AT MASS CITY IN ONTONAGON COUNTY. PRECIPITATION TOTALS JUST 
TO THE EAST DECREASED RAPIDLY...AND A SWATH FROM IRON COUNTY TO 
MARQUETTE PICKED UP LESS THAN 0.10 INCH OF RAIN. A FINAL ROUND OF 
THUNDERSTORMS AFFECTED UPPER MICHIGAN ON 8/26-8/27 AS A COLD FRONT 
ASSOCIATED WITH A DEEPENING UPPER TROUGH IN SOUTHERN CANADA SMASHED 
INTO THE RIDGE AND UNSTABLE AIRMASS IN PLACE. SOME OF THE 
THUNDERSTORMS DROPPED HEAVY RAIN AND TURNED SEVERE. IN MARQUETTE 
COUNTY...ONE STORM BOMBARDED A LOCATION JUST SOUTHEAST OF HARVEY 
WITH GOLFBALL-SIZED HAIL. AT LEAST AN INCH OF RAIN FELL ALONG A LINE 
FROM NORWAY IN DICKINSON COUNTY TO MUNISING...AND SKANDIA IN EASTERN 
MARQUETTE COUNTY LOGGED 1.61 INCHES OF PRECIPITATION. RAINFALL 
TOTALS OVER THE FAR WEST AND NEAR LAKE MICHIGAN WERE MUCH LESS.

THE STRENGTHENING TROUGH DROPPED YET ANOTHER CHILLY AIRMASS INTO THE 
UPPER GREAT LAKES AT MONTH'S END. DAILY TEMPERATURES ON 8/28-8/31 
RAN CLOSE TO 10 DEGREES BELOW NORMAL. THERE WAS QUITE A BIT OF CLOUD 
COVER AND EVEN A FEW SHOWERS DURING THIS TIME...AND A FEW MORE 
RECORD LOW MAXIMUM TEMPERATURES WERE ESTABLISHED ON 8/28 AND 8/29. 
BOTH THE MARQUETTE NWS AND IRONWOOD OBSERVED A HIGH OF 55 ON 
8/28...TYING THE PREVIOUS RECORD LOW MAXIMUM FOR THE DATE AT BOTH 
SPOTS. THE RECORD AT IRONWOOD HAD STOOD ALONE SINCE 1903. THE CLOUD 
COVER TENDED TO HOLD UP MORNING TEMPERATURES...BUT THE MERCURY AT 
IRONWOOD REACHED 36 AT DAWN ON 8/29.

SOME OTHER TEMPERATURE AND PRECIPITATION OBSERVATIONS ACROSS UPPER 
MICHIGAN IN AUGUST 2004 INCLUDE:

IRONWOOD...AVERAGE TEMPERATURE 58.6 (4.9 DEGREES BELOW NORMAL)
           PRECIPITATION 5.44 INCHES (1.72 INCHES ABOVE NORMAL)

WAKEFIELD (GOGEBIC COUNTY)...PRECIPITATION 5.43 INCHES

                       AUGUST WEATHER SUMMARY

TRANQUIL WEATHER WAS THE RULE AS THE CALENDAR CHANGED FROM JULY TO 
AUGUST. A RIDGE OF HIGH PRESSURE PASSED TO THE EAST DURING THE 
MORNING...AND A WARMER AND MORE HUMID SOUTH WIND DEVELOPED ON 8/1. 
THE MERCURY STARTED THE DAY BETWEEN 49 AND 57...THEN ROSE TO 77 TO 
87 DURING THE AFTERNOON...EXCEPT ONLY 70 TO 76 ALONG THE COOLER LAKE 
MICHIGAN SHORE. MORNING SUNSHINE GAVE WAY TO A MIX OF SUN AND 
CLOUDS. ALTHOUGH SOME ISOLATED SHOWERS DEVELOPED WITH THE HEATING OF 
THE DAY OVER SOUTHERN UPPER MICHIGAN...RAINFALL AMOUNTS WERE LESS 
THAN 0.10 INCH. LOWS DURING THE OVERNIGHT ON 8/1-8/2 WERE 55 TO 65. 
THEN A STRONG COLD FRONT PASSED OVER UPPER MICHIGAN ON 8/2. THE 
ARRIVAL OF THIS FRONT AND DAYTIME HEATING TRIGGERED SOME SHOWERS AND 
THUNDERSTORMS...MAINLY OVER SOUTH CENTRAL AND EASTERN UPPER 
MICHIGAN. SOME OF THE STORMS BECAME SEVERE AND PRODUCED TORRENTIAL 
DOWNPOURS. GLADSTONE IN DELTA COUNTY WAS DELUGED BY 3.30 INCHES OF 
RAIN. THIS HEAVY RAIN CAUSED SOME FLOODING...WHICH CLOSED PORTIONS 
OF M-35. LARGE HAIL AND DAMAGING WINDS WERE NOTED AS WELL ACROSS 
PORTIONS OF DELTA AND SCHOOLCRAFT COUNTIES. COOLER AIR ARRIVED 
BEHIND THE FRONT IN THE AFTERNOON OVER THE NORTHWEST AND IN THE 
EVENING ACROSS THE SOUTH CENTRAL AND EAST BEHIND THE FRONT. DAYTIME 
HIGHS REACHED 75 TO 85 AT MOST PLACES...EXCEPT 70 TO 75 OVER THE 
WEST WHERE THE FRONT ARRIVED EARLIER IN THE DAY.

COOLER AIR CONTINUED TO PUSH SLOWLY INTO UPPER MICHIGAN DURING THE 
OVERNIGHT ON 8/2-8/3 AS A NORTH FLOW DEVELOPED IN ADVANCE OF A 
CANADIAN HIGH PRESSURE CENTER. TEMPERATURES AT DAWN ON 8/3 RANGED 
FROM 47 AT CHAMPION IN MARQUETTE COUNTY TO 63 AT MENOMINEE UNDER A 
MAINLY CLEAR SKY. BUT THE MORNING SUNSHINE GAVE WAY TO PARTLY SUNNY 
SKIES AS DAYTIME HEATING DESTABILIZED THE COOLER AIRMASS MAKING 
GREATER INROADS INTO THE UPPER GREAT LAKES. AFTERNOON HIGHS REACHED 
BETWEEN 70 ALONG LAKE SUPERIOR AND 82 AT STEPHENSON IN MENOMINEE 
COUNTY AND MCMILLAN IN LUCE COUNTY. THE CLOUDS TENDED TO DISSOLVE 
AFTER THE SUN WENT DOWN ON 8/3...AND THE MERCURY FELL OFF SHARPLY TO 
AS LOW AS 39 AT CHAMPION AND 42 AT WATERSMEET IN GOGEBIC COUNTY BY 
DAWN ON 8/4. THE LOW AT MOST PLACES WAS 45 TO 55...BUT REMAINED AS 
HIGH AS 58 AT STEPHENSON AND IN THE CITY OF MARQUETTE RIGHT ALONG 
THE RELATIVELY WARM NEARSHORE WATERS OF LAKE SUPERIOR. THE AFTERNOON 
OF 8/4 WAS A CARBON COPY OF THE DAY BEFORE WITH A MIX OF SUN AND 
CLOUDS. BUT HIGHS WERE QUITE A BIT COOLER THAN ON 8/3 WITH READINGS 
RANGING FROM 65 ALONG THE LAKE SUPERIOR SHORE TO 79 AT CORNELL IN 
DELTA COUNTY. SKIES BECAME CRYSTAL CLEAR DURING THE OVERNIGHT ON 
8/4-8/5...AND TEMPERATURES PLUMMETED AS LOW AS 33 AT WATERSMEET. 
READINGS WERE IN THE 40S AT MOST OTHER PLACES...EXCEPT THE LOW 50S 
RIGHT ALONG THE LAKESHORES. THE CENTER OF THE HIGH WAS CLOSER ON 8/5 
THAN ON THE PREVIOUS TWO DAYS...SO BRIGHT BLUE SKIES WERE THE RULE 
DURING THE DAY. DESPITE THE BRILLIANT SUNSHINE...A COOL NORTH WIND 
OFF LAKE SUPERIOR HELD MAXIMUM TEMPERATURES IN THE 65 TO 75 RANGE. 
THE OVERNIGHT OF 8/5-8/6 WAS ANOTHER CHILLY ONE WITH CLEAR SKIES 
UNDER THE HIGH PRESSURE SYSTEM. BUT TEMPERATURES DID NOT FALL AS 
SHARPLY BECAUSE THE WIND WAS A BIT STRONGER THAN THE NIGHT BEFORE. 
TEMPERATURES AT THE INTERIOR COOL SPOTS FELL INTO THE 40S AND EVEN 
AS LOW AS 36 AT WATERSMEET BUT REMAINED IN THE 50S AT PLACES WHERE 
THE WIND WAS A LITTLE STRONGER. ALTHOUGH AFTERNOON READINGS ALONG 
THE LAKE SUPERIOR SHORE REACHED ONLY THE UPPER 60S ON 8/6... 
THERMOMETERS PEAKED IN THE 70S OVER MOST INLAND LOCATIONS AND UP TO 
80 AT STEPHENSON AND MCMILLAN. THE OVERNIGHT ON 8/6-8/7 WAS CLEAR 
AGAIN...AND TEMPERATURES FELL TO 35 AT CHAMPION. LOWS ELSEWHERE WERE 
GENERALLY IN THE 40S...EXCEPT 50 TO 55 ALONG THE LAKE SUPERIOR SHORE.

THE DOMINATING RIDGE OF HIGH PRESSURE BEGAN TO BREAK DOWN ON 8/7 AS 
AN UPPER AIR DISTURBANCE MOVED TOWARD THE UPPER GREAT LAKES. 
ALTHOUGH SOME LIGHT SHOWERS FELL WEST OF A LINE FROM ONTONAGON TO 
IRON RIVER...THE HIGH WAS STILL STRONG ENOUGH TO DRY UP ANY 
PRECIPITATION THAT TRIED TO MOVE FARTHER EAST. EVEN WHERE RAIN 
FELL...AMOUNTS WERE LESS THAN 0.10 INCH. MAXIMUM TEMPERATURES WERE 
72 TO 82 AT MOST SPOTS...BUT ONLY 65 TO 70 OVER THE FAR WEST WHERE 
THERE WAS MORE CLOUD COVER AND SOME LIGHT RAIN. LOWS DURING THE 
OVERNIGHT ON 8/7-8/8 WERE HELD UP BY MORE CLOUD COVER AND MAINLY IN 
THE 50S...EXCEPT 45 TO 50 AT SOME OF THE COOLER INLAND PLACES. THE 
APPROACH OF ANOTHER UPPER AIR DISTURBANCE ON 8/8 WEAKENED THE HIGH 
EVEN MORE...RESULTING IN A GREATER COVERAGE OF SHOWERS AND EVEN A 
FEW THUNDERSTORMS. THE MOST PRECIPITATION FELL ACROSS THE NORTH... 
WHERE MUNISING MEASURED 1.06 INCHES OF RAIN. MOST PLACES ACROSS THE 
SOUTHERN COUNTIES SAW LESS THAN 0.10 INCH. WIDESPREAD CLOUD COVER 
SUPPRESSED THE DIURNAL TEMPERATURE INCREASE...AND HIGHS ON 8/8 WERE 
MAINLY IN THE 70S. SCATTERED SHOWERS AND A FEW THUNDERSTORMS 
CONTINUED DURING THE OVERNIGHT ON 8/8-8/9. WITH THE CLOUD COVER 
REMAINING IN PLACE AND A HUMID SOUTHWEST WIND...LOWS REMAINED 60 TO 
66. THE CLOUDS GAVE WAY TO SOME SUNSHINE BY THE AFTERNOON ON 8/9. 
SOLAR HEATING AND DESTABILIZATION OF THE WARM AND HUMID AIRMASS AS 
WELL AS THE APPROACH OF A STRONG UPPER DISTURBANCE AND COLD FRONT 
WERE MORE THAN ENOUGH TO TRIGGER NUMEROUS SHOWERS AND THUNDERSTORMS 
IN THE AFTERNOON AND EARLY EVENING. SOME OF THESE STORMS EAST OF 
IRON MOUNTAIN AND MARQUETTE BECAME SEVERE...DROPPING LARGE HAIL 
AND/OR CAUSING DAMAGING WINDS IN MENOMINEE...MARQUETTE...AND DELTA 
COUNTIES. HAIL AS LARGE AS GOLFBALLS FELL JUST SOUTH OF HARVEY IN 
MARQUETTE COUNTY UNDER THE MOST INTENSE THUNDERSTORM. ALMOST 
EVERYWHERE EXCEPT THE SOUTHERN HALF OF MENOMINEE COUNTY PICKED UP AT 
LEAST 0.25 INCH OF RAIN...AND AS MUCH AS 1.25 INCH FELL AT PELKIE ON 
THE BARAGA-HOUGHTON COUNTY LINE. IRON MOUNTAIN AND IRONWOOD BOTH 
LOGGED 1.12 INCHES IN THE GAUGE...AND JACOBSVILLE IN HOUGHTON COUNTY 
MEASURED 1.03 INCHES. DAYTIME TEMPERATURES PEAKED BETWEEN 67 AT 
MCMILLAN AND 82 AT STEPHENSON AND SPALDING IN MENOMINEE COUNTY.

COOLER AIR MOVED INTO THE U.P. FOLLOWING A WEAK COLD FRONTAL PASSAGE 
DURING THE OVERNIGHT ON 8/9-8/10...AND LOWS AT DAWN ON 8/10 FELL 
INTO THE 50S WITH READINGS DOWN TO 49 AT PHOENIX IN KEWEENAW COUNTY. 
A STRONGER COLD FRONT...ACCOMPANIED BY SOME SCATTERED SHOWERS... 
PLOWED ACROSS THE AREA IN THE MORNING ON 8/10. THE WIDESPREAD CLOUD 
COVER AND SURGE OF COOLER AIR BEHIND THE FRONT MADE THE DAY FEEL 
MORE LIKE AUTUMN THAN MID SUMMER. ALTHOUGH THE MERCURY REACHED 66 AT 
NEWBERRY AND STEPHENSON...TEMPERATURES WHERE THE FRONT PASSED 
EARLIEST TOPPED OUT AT ONLY 51 AT IRONWOOD AND 52 AT PHOENIX. THE 51 
DEGREE HIGH AT IRONWOOD SMASHED THE PREVIOUS RECORD LOW MAXIMUM 
TEMPERATURE OF 59 FOR 8/10 THAT HAD STOOD SINCE 1903. SHOWERS PICKED 
UP LATER IN THE DAY OVER WESTERN UPPER MICHIGAN WITH THE APPROACH OF 
ANOTHER STRONG UPPER AIR DISTURBANCE...ADDING TO THE GLOOM OF THE 
DAY. THE CLOUDS...SHOWERS...AND AUTUMNAL CHILL CONTINUED THROUGH THE 
DAY ON 8/11. TEMPERATURES AT DAWN ON 8/11 WERE 42 TO 50...AND 
READINGS COULD REBOUND ONLY TO BETWEEN 49 AT IRONWOOD AND WATTON AND 
61 AT STEPHENSON...READINGS MORE NORMAL FOR MID APRIL OR MID 
OCTOBER. FOR THE SECOND DAY IN A ROW...IRONWOOD ON 8/11 SAW ITS 
PREVIOUS RECORD LOW MAXIMUM TEMPERATURE DEMOLISHED...WITH THE 49 
DEGREE HIGH EASILY ECLIPSING THE STANDARD OF 55 LOGGED ON 8/11/1964. 
THE MARQUETTE NWS RECORDED A HIGH OF 52...ALMOST 10 DEGREES LOWER 
THAN THE PREVIOUS RECORD LOW MAXIMUM OF 60 OBSERVED ON 8/11/1992.  
TOTAL RAINFALL ON 8/10-8/11 WAS HEAVIEST ACROSS THE WEST...INCLUDING 
2.20 INCHES AT ATLANTIC MINE IN HOUGHTON COUNTY...2.00 INCHES AT 
PHOENIX...1.48 INCHES AT IRONWOOD...1.40 INCHES AT BIG BAY IN 
MARQUETTE COUNTY...AND 1.37 INCHES AT BRUCE CROSSING IN ONTONAGON 
COUNTY. PRECIPITATION AMOUNTS TAILED OFF SHARPLY FARTHER EAST...0.61 
INCH AT MUNISING...0.55 INCH AT THE MARQUETTE NWS...0.25 INCH AT 
NEWBERRY...0.24 INCH AT STEPHENSON... AND A MINUSCULE 0.01 INCH AT 
IRON MOUNTAIN.

SKIES CLEARED OVER WESTERN UPPER MICHIGAN DURING THE OVERNIGHT ON 
8/11-8/12 AND OVER THE EAST DURING THE DAY ON 8/12 AS CANADIAN HIGH 
PRESSURE APPROACHED FROM THE WEST. THE THERMOMETER RESPONDED TO THE 
CLEARING OVER THE WEST BY DROPPING AS LOW AS A FROSTY 32 AT 
WATERSMEET...37 AT PHOENIX...AND 39 AT BARAGA. LOWS FARTHER EAST 
WERE IN THE 40S. ALTHOUGH THE AIRMASS REMAINED QUITE CHILLY...THE 
RETURN OF SUNSHINE HELPED WARM AFTERNOON HIGHS ON 8/12 INTO THE 60S. 
THE OVERNIGHT ON 8/12-8/13 WAS ANOTHER CHILLY ONE AS WINDS 
DIMINISHED AS THE HIGH CLOSED IN ON THE AREA. THERE WAS PATCHY FROST 
OVER INTERIOR WESTERN UPPER MICHIGAN...WHERE THE MERCURY FELL INTO 
THE 30S AND AS LOW AS 31 AT WATERSMEET...33 AT CHAMPION...AND 35 AT 
WATTON. TEMPERATURES NEAR THE SHORE AND FARTHER EAST WERE IN THE 
40S. THE HIGH PRESSURE SYSTEM BROUGHT PARTLY TO MOSTLY SUNNY SKIES 
ON 8/13 AND 8/14 EVEN THOUGH THERE WERE A FEW LIGHT INSTABILITY 
SHOWERS NEAR THE WISCONSIN BORDER ON 8/13. HIGHS ON 8/13 WERE 62 TO 
72...AND 66 TO 75 ON 8/14. TEMPERATURES DURING THE OVERNIGHT ON 
8/13-8/14 BOTTOMED OUT IN THE 30S OVER THE INTERIOR COLDER AREAS AND 
DOWN TO 31 AT CHAMPION BUT REMAINED IN THE 40S NEAR THE GREAT LAKES 
SHORES. THE HIGH REMAINED DOMINANT ON 8/15...BUT THE DAY TURNED  
WARMER ONCE THE CENTER SHIFTED TO THE EAST AND A SOUTHERLY FLOW 
DEVELOPED. THE WARMING TREND BEGAN DURING THE OVERNIGHT ON 8/14-8/15 
WITH THE SOUTH WIND HOLDING MINIMUM TEMPERATURES UP IN THE 44 TO 54 
RANGE AT MOST PLACES EVEN UNDER CLEAR SKIES. A FEW COLD SPOTS LIKE 
CHAMPION DID RECORD LOWS BETWEEN 35 AND 40. THE MERCURY ROSE WELL 
INTO THE 70S EVERYWHERE ON 8/15...BUT REMAINED IN THE 65 TO 70 RANGE 
DOWNWIND OF LAKE MICHIGAN. OVERNIGHT TEMPERATURES ON 8/15-8/16 FELL 
INTO THE 50S...EXCEPT INTO THE 40S OVER SHELTERED INTERIOR 
LOCATIONS.

A LOW PRESSURE TROUGH APPROACHING FROM THE WEST CAUSED AN INCREASE 
IN CLOUDS ON 8/16. SCATTERED SHOWERS ACCOMPANYING THIS SYSTEM 
DEVELOPED OVER WESTERN UPPER MICHIGAN IN THE AFTERNOON...THEN SPREAD 
INTO THE EASTERN U.P. DURING THE OVERNIGHT ON 8/16-8/17 BEFORE 
ENDING BY DAWN ON 8/17. MOST PLACES RECORDED NO MORE THAN 0.10 INCH 
OF RAIN...BUT COOKS IN SCHOOLCRAFT COUNTY MEASURED 0.26 INCH. HIGHS 
ON 8/16 RANGED FROM 61 AT IRONWOOD TO 75 AT CORNELL IN DELTA 
COUNTY...BIG BAY...AND MARQUETTE. TEMPERATURES AT DAWN ON 8/17 FELL 
INTO THE 50S AT MOST PLACES...BUT REMAINED AS HIGH AS 62 AT 
MANISTIQUE. 8/17 TURNED OUT TO BE PARTLY SUNNY AND RATHER HUMID... 
WITH HIGH TEMPERATURES CLIMBING TO BETWEEN 68 AND 76. SOME SHOWERS 
AND THUNDERSTORMS ERUPTED DURING THE AFTERNOON AS ANOTHER LOW 
PRESSURE TROUGH PASSED THE UPPER GREAT LAKES. MANISTIQUE REPORTED 
THE MOST RAIN...0.19 INCH. UNDER A PARTLY CLOUDY SKY...OVERNIGHT 
LOWS ON 8/17-8/18 WERE 43 AT CHAMPION TO 59 ALONG THE LAKESHORE IN 
MARQUETTE. THE MORNING OF 8/18 WAS DRY...BUT A POWERFUL COLD FRONT 
SWEPT ACROSS THE U.P. DURING THE AFTERNOON. SCATTERED SHOWERS AND A 
FEW THUNDERSTORMS ACCOMPANIED THE FRONTAL PASSAGE. A THUNDERSTORM IN 
MENOMINEE COUNTY PRODUCED WIND GUSTS IN EXCESS OF 60 MPH AND FELLED 
LARGE TREES NEAR STEPHENSON. A FEW PLACES GOT BRIEF HEAVY DOWNPOURS 
AS WELL...INCLUDING A 0.91 INCH DELUGE IN 15 MINUTES AT DAGGETT IN 
MENOMINEE COUNTY. BUT THE HEAVIER RAINFALL WAS VERY SPOTTY WITH SOME 
PLACES PICKING UP JUST A FEW HUNDREDTHS OF AN INCH. STRONG WINDS 
WERE THE MOST NOTABLE ASPECT OF THIS SYSTEM. A GUSTY SOUTHWEST WIND 
TURNED SHARPLY TO THE NORTHWEST SOON AFTER THE FRONTAL PASSAGE...AND 
WIND GUSTS APPROACHED 60 MPH OVER THE KEWEENAW PENINSULA. THE STRONG 
WINDS BLEW DOWN SOME TREES AND CAUSED POWER OUTAGES OVER THE 
KEWEENAW. MAXIMUM TEMPERATURES ON 8/18 WERE IN THE 70S AT MOST SPOTS 
BUT UP TO 80 AT STEPHENSON.

AFTER A SECOND UPPER DISTURBANCE TRACKING ACROSS ONTARIO CAUSED SOME 
SCATTERED SHOWERS OVER THE KEWEENAW PENINSULA DURING THE OVERNIGHT 
ON 8/18-8/19 AND DROPPED UP TO 0.19 INCH OF RAIN AT PHOENIX...A COOL 
AND GUSTY WEST WIND BEHIND THE COLD FRONT AND IN ADVANCE OF HIGH 
PRESSURE SINKING SOUTH THROUGH THE CANADIAN PRAIRIES DOMINATED THE 
WEATHER ON 8/19. LOWS AT DAWN BOTTOMED OUT IN THE 30S OVER MOST 
INTERIOR LOCATIONS AND AS LOW AS 33 AT CHAMPION...BUT REMAINED IN 
THE 40S NEAR THE WARMER LAKESHORES. DESPITE PARTLY TO MOSTLY SUNNY 
SKIES IN THE AFTERNOON ON 8/19...THE MERCURY CLIMBED ONLY TO 62 TO 
70 IN THE AFTERNOON. WIND GUSTS UP TO 40 MPH OVER THE KEWEENAW 
PENINSULA MADE THE AIR FEEL EVEN COOLER. THE CANADIAN HIGH PRESSURE 
SYSTEM BROUGHT A MOSTLY SUNNY BUT COOL AND BREEZY DAY TO UPPER 
MICHIGAN ON 8/20. TEMPERATURES STARTED THE DAY BETWEEN 36 AT 
CHAMPION AND 53 AT MANISTIQUE...THEN RECOVERED TO 57 OVER THE 
KEWEENAW PENINSULA TO 68 AT STEPHENSON DURING THE AFTERNOON. THE 
HIGH PRESSURE BROUGHT ANOTHER MOSTLY SUNNY DAY ON 8/21. SINCE THE 
HIGH CENTER PUSHED CLOSER TO THE U.P....THE WIND WAS NOT AS STRONG 
AS ON THE DAYS BEFORE. AT DAWN...THE THERMOMETER READ 35 TO 40 AT 
MOST INTERIOR LOCATIONS AND EVEN A FROSTY 34 AT FORD AIRPORT NEAR 
IRON MOUNTAIN...BUT REGISTERED 40 TO 50 NEAR THE SHORES. HIGHS ON 
8/21 WERE 61 AT MUNISING TO 72 AT BARAGA...STEPHENSON...AND CHAMPION.

ANOTHER COOL FRONT IN THE PERSISTENT NORTHWEST FLOW ALOFT CROSSED 
UPPER MICHIGAN ON 8/22...BRINGING SCATTERED SHOWERS TO THE AREA. THE 
SOUTHERLY FLOW AHEAD OF THIS FRONT DURING THE OVERNIGHT ON 8/21-8/22 
PREVENTED TEMPERATURES FROM FALLING ANYWHERE NEAR AS LOW AS AT DAWN 
8/21...BUT THE MERCURY STILL REACHED 37 AT CHAMPION EARLY IN THE 
NIGHT BEFORE THE ARRIVAL OF THE STRONGER WINDS. MOST PLACES SAW LOWS 
IN THE 45 TO 55 RANGE...BUT THE THERMOMETER NEVER FELL BELOW 58 AT 
MANISTIQUE. THE HEAVIEST RAIN ON 8/22 FELL OVER NORTHERN UPPER 
MICHIGAN...WHERE MOST PLACES LOGGED AT LEAST 0.25 INCH. CALUMET 
MEASURED 0.72 INCH...BUT LOCATIONS ACROSS THE SOUTH PICKED UP 
NOTHING TO JUST A FEW HUNDREDTHS OF AN INCH. MAXIMUM TEMPERATURES 
TOPPED OUT BETWEEN 66 AT MANISTIQUE AND 82 AT STEPHENSON. COOL AIR 
WAS SLOW TO FILTER IN BEHIND THE COOL FRONT...AND LOWS AT DAWN ON 
8/23 WERE 43 TO 52. HIGH PRESSURE BUILDING ACROSS ONTARIO BROUGHT A 
PARTLY SUNNY AND COOL DAY TO THE AREA ON 8/23. HIGHS REACHED 70 AT 
STEPHENSON...BUT REMAINED IN THE UPPER 50S NEAR LAKE SUPERIOR.

THE UPPER AIR PATTERN BEGAN SHIFTING TO A RIDGE OVER THE GREAT LAKES 
BY 8/24. READINGS DURING THE OVERNIGHT ON 8/23-8/24 FELL AS LOW AS  
39 AT CHAMPION BEFORE INCREASING CLOUDS AHEAD OF AN APPROACHING WARM 
FRONT HALTED THE DIURNAL FALL IN TEMPERATURE. THE MERCURY REACHED 
THE 40S AT MOST PLACES...BUT REMAINED AS HIGH AS 58 AT MANISTIQUE 
AND 57 AT ESCANABA AND MENOMINEE WHERE THE CLOUD COVER MOVED IN 
FASTER CLOSER TO THE WARM FRONT. SOME SHOWERS ASSOCIATED WITH THE 
WARM FRONT DEVELOPED ON 8/24...AND SOME OF THE RAIN OVER CENTRAL AND 
EASTERN UPPER MICHIGAN WAS HEAVY BEFORE ENDING DURING THE OVERNIGHT 
ON 8/24-8/25 WITH THE PASSAGE OF THE WARM FRONT. MOST LOCATIONS FROM 
MARQUETTE AND IRON MOUNTAIN EAST SAW 0.50 TO 1.00 INCH OF RAIN...BUT 
MANY PLACES OVER THE FAR WEST RECORDED ONLY A FEW HUNDREDTHS OF AN 
INCH. SOME OF THE MORE SIGNIFICANT PRECIPITATION REPORTS INCLUDE 
1.57 INCHES AT COOKS AND 1.53 INCHES AT THE MARQUETTE NWS. THE 
CLOUDS AND RAIN HELD HIGH TEMPERATURES ON 8/24 BETWEEN 65 AND 75 
DESPITE THE ARRIVAL OF THE WARM FRONT. THIS FRONT PASSED DURING THE 
OVERNIGHT ON 8/24-8/25...AND MINIMUM TEMPERATURES FELL TO ONLY 57 TO 
64 WITH THE ARRIVAL OF THE WARMER AIR. THE WEATHER ON 8/25 WAS WARM 
AND RATHER HUMID...BUT HIGH TEMPERATURES WERE HELD DOWN A BIT BY 
CLOUD COVER. READINGS RANGED FROM 68 BY THE LAKE MICHIGAN SHORE AT 
MANISTIQUE AND 83 AT BARAGA. THE SURFACE HEATING RESULTED IN SOME 
ISOLATED THUNDERSTORMS OVER THE WESTERN U.P. DURING THE AFTERNOON... 
AND THESE SHOWERS BECAME MORE WIDESPREAD DURING THE OVERNIGHT ON 
8/25-8/26 OVER ALL BUT CENTRAL UPPER MICHIGAN. RAINFALL OVER THE 
WEST FROM IRONWOOD TO BARAGA BECAME EXCESSIVE IN SOME AREAS...WITH 
UP TO 5 INCHES FALLING NEAR BOB LAKE IN HOUGHTON COUNTY...3.88 
INCHES AT BARAGA...2.25 INCHES AT PELKIE NEAR THE BARAGA-HOUGHTON 
COUNTY LINE...1.60 INCHES AT IRONWOOD AND 1.52 INCHES AT MASS CITY 
IN ONTONAGON COUNTY. MOST PLACES FROM MENOMINEE TO NEWBERRY LOGGED 
0.25 TO 0.50 INCH OF RAIN...BUT THE AREA BETWEEN THIS SWATH AND THE 
AXIS OF HEAVY RAIN IN THE WEST SAW NO MORE THAN 0.10 INCH. LOWS AT 
DAWN ON 8/26 WERE A HUMID 58 TO 66. WARM AND HUMID WEATHER CONTINUED 
ON 8/26 AS UPPER MICHIGAN REMAINED IN A SOUTHWEST FLOW UNDER THE 
UPPER RIDGE. AFTERNOON TEMPERATURES PEAKED IN THE 73 TO 83 RANGE... 
BUT REMAINED 65 TO 73 FROM MANISTIQUE TO NEWBERRY WHERE MORE CLOUD 
COVER LINGERED THROUGH THE DAY DOWNWIND OF LAKE MICHIGAN. SCATTERED 
SHOWERS AND THUNDERSTORMS DEVELOPED DURING THE DAY AND CONTINUED 
DURING THE OVERNIGHT OF 8/26-8/27 WITH THE APPROACH OF A LOW 
PRESSURE TROUGH. SOME OF THE THUNDERSTORMS DROPPED HEAVY RAIN AND 
TURNED SEVERE. IN MARQUETTE COUNTY...ONE STORM BOMBARDED A LOCATION 
JUST SOUTHEAST OF HARVEY WITH GOLFBALL-SIZED HAIL. AT LEAST AN INCH 
OF RAIN FELL ALONG A LINE FROM NORWAY IN DICKINSON COUNTY TO 
MUNISING...AND SKANDIA IN EASTERN MARQUETTE COUNTY LOGGED 1.61 
INCHES OF PRECIPITATION. MOST PLACES FROM IRONWOOD THROUGH THE 
KEWEENAW PENINSULA AND AROUND MANISTIQUE SAW NO MORE THAN 0.10 INCH 
OF RAIN. DRIER AIR ARRIVED OVER THE WESTERN COUNTIES OF UPPER 
MICHIGAN BEHIND THE LOW PRESSURE TROUGH DURING THE OVERNIGHT ON 
8/26-8/27...AND TEMPERATURES AT DAWN ON 8/27 FELL OFF INTO THE 50S 
OVER THE WEST AND AS LOW AS 53 AT WATERSMEET. READINGS OVER THE EAST 
REMAINED 60 TO 65.

COOLER AIR BEGAN FILTERING INTO UPPER MICHIGAN ON 8/27 AS A GUSTY 
WEST WIND THAT EXCEEDED 40 MPH AT HOUGHTON FOLLOWED THE PASSAGE OF A 
COLD FRONT. THERE WAS A MIX OF SUN AND CLOUDS...BUT MAXIMUM 
TEMPERATURES REACHED ONLY 65 TO 70 OVER THE WEST. HIGHS ROSE TO 80 
TO 85 OVER THE EAST WHERE THE COOLER AIR WAS LAST TO ARRIVE. BY DAWN 
ON 8/28...THERMOMETERS HAD FALLEN OFF TO BETWEEN 46 AND 54. A NORTH 
WIND OFF LAKE SUPERIOR BETWEEN HIGH PRESSURE IN THE PLAINS AND A LOW 
PRESSURE SYSTEM TRACKING THROUGH THE CENTRAL GREAT LAKES DELIVERED 
MUCH COOLER DAYS ON 8/28 AND 8/29. SKIES WERE MOSTLY CLOUDY AND 
THERE WERE SOME SHOWERS...ESPECIALLY OVER THE EAST CLOSER TO THE LOW 
PRESSURE PATH AND JUST DOWNWIND OF LAKE SUPERIOR. RAINFALL AMOUNTS 
WERE 0.10 INCH OR LESS. HIGHS REACHED ONLY THE 50S TO 65...AND SOME 
RECORD LOW MAXIMUM TEMPERATURES WERE TIED OR BROKEN. BOTH THE 
MARQUETTE NWS AND IRONWOOD OBSERVED A HIGH OF 55 ON 8/28...TYING THE 
PREVIOUS RECORD LOW MAXIMUM FOR THE DATE. THE RECORD AT IRONWOOD HAD 
STOOD ALONE SINCE 1903. MORNING LOWS ON 8/29 WERE 36 AT IRONWOOD TO 
52 AT THE LAKESHORE IN COPPER HARBOR.

SOME SCATTERED SHOWERS DEVELOPED DURING THE EARLY MORNING HOURS ON 
8/30 AS A LOW PRESSURE TROUGH SWUNG THROUGH THE NORTHWEST GREAT 
LAKES. THESE SHOWERS ENDED BY NOON OVER THE WEST AND DURING THE 
AFTERNOON ACROSS THE EAST. ALTHOUGH MOST PLACES SAW 0.10 INCH OF 
RAIN OR LESS...MANISTIQUE MEASURED 0.32 INCH AND IRONWOOD 0.24 INCH. 
LOWS AT DAWN ON 8/30 WERE GENERALLY 40 TO 50...BUT AS HIGH AS 54 AT 
MANISTIQUE. MAXIMUM TEMPERATURES ON 8/30 RANGED FROM 61 AT MCMILLAN 
TO 75 AT IRON MOUNTAIN AND STEPHENSON. THE MERCURY FELL AS LOW AS 39 
AT CHAMPION AND REMAINED AS HIGH AS 56 AT MANISTIQUE AT DAWN ON 
8/31...BUT REACHED 43 TO 53 AT MOST PLACES. MORNING SUNSHINE ON 8/31 
GAVE WAY TO MORE CLOUDS AND SCATTERED SHOWERS DURING THE DAY ON 8/31 
AS ANOTHER QUICK-MOVING LOW PRESSURE TROUGH MOVED ACROSS THE U.P. 
RAINFALL WAS GENERALLY JUST A FEW HUNDREDTHS OF AN INCH. AFTERNOON 
HIGHS WERE 57 AT COPPER HARBOR TO 75 AT STEPHENSON.

                        SEPTEMBER CLIMATOLOGY
 
AVERAGE TEMPERATURES IN SEPTEMBER BEGIN TO FALL SHARPLY...ABOUT 8 TO 
9 DEGREES LOWER THAN IN AUGUST...AS SUMMER TRANSITIONS TO AUTUMN AND 
DAYLIGHT GROWS SHORTER. THE AUTUMNAL EQUINOX THIS YEAR ARRIVES AT 
1225 AM EDT ON 9/22. POSSIBLE SUNSHINE IN SEPTEMBER DECLINES FROM 
800 MINUTES ON 9/1 TO 706 MINUTES ON 9/30...A DECREASE OF 3 TO 4 
MINUTES EACH DAY.

ALTHOUGH THE DAYS GROW SHORTER DURING THE NINTH MONTH...MID SUMMER  
LIKE WARMTH CAN STILL GRIP UPPER MICHIGAN DURING SEPTEMBER. ON 
9/12/98...RESIDENTS OF IRON MOUNTAIN SIZZLED IN 98 DEGREE HEAT. BOTH 
IRON MOUNTAIN AND IRONWOOD RECORDED HIGH TEMPERATURES ABOVE 90 FIVE 
DAYS IN A ROW DURING A TORRID MID SEPTEMBER HEATWAVE BETWEEN 9/8 AND 
9/12 IN 1931. WITH TEMPERATURES AVERAGING 7 TO 8 DEGREES ABOVE 
NORMAL...SEPTEMBER 1931 GOES DOWN IN THE RECORD BOOKS AS THE WARMEST 
SEPTEMBER EVER OBSERVED AT IRON MOUNTAIN AND IRONWOOD. RECENT 
SEPTEMBERS HAVE AVERAGED ON THE WARM SIDE. IN FACT AT THE MARQUETTE 
NWS...NEWBERRY...AND MANISTIQUE...SEPTEMBER 2002 IS THE WARMEST 
SINCE RECORDS BEGAN AT THOSE SITES. MUNISING...ONTONAGON...AND 
MICHIGAN TECH UNIVERSITY RECORDED THEIR SECOND WARMEST SEPTEMBER IN 
2002...AND IRON MOUNTAIN LOGGED THE FIFTH WARMEST.

BUT WINTER OFTEN MAKES ITS FIRST RETURN BY LATE IN THE MONTH. THE 
GROWING SEASON ENDS EVERYWHERE EXCEPT ALONG THE WARMER GREAT LAKES 
SHORES DURING SEPTEMBER WITH AN INCREASED PROBABILITY OF KILLING 
FROST. RECORD LOW TEMPERATURES OVER INLAND AREAS FALL INTO THE 20S 
DURING THE MONTH AND EVEN INTO THE UPPER TEENS AT MANY LOCATIONS 
TOWARD MONTHS END. ON 9/22/95...THE WESTERN UPPER PENINSULA WAS 
STRUCK WITH AN EARLY SEASON SNOWSTORM. IRONWOOD PICKED UP 6.5 
INCHES...AND HOUGHTON ALSO SAW 3 INCHES OF THE WHITE STUFF THAT DAY. 
AT LEAST AN INCH OF SNOW HAS FALLEN ON PORTIONS OF UPPER MICHIGAN 
DURING LATE SEPTEMBER IN 1965...1974...1989...AND 1993.

AS THE JET STREAM SINKS FARTHER SOUTH DURING SEPTEMBER AND INTERACTS 
WITH FAIRLY WARM AND HUMID AIRMASSES STILL RESIDENT OVER THE UNITED 
STATES...AVERAGE MONTHLY PRECIPITATION OVER MUCH OF UPPER MICHIGAN 
PEAKS AT A YEARLY MAXIMUM BETWEEN 3.5 AND 4.0 INCHES. ALTHOUGH 
CONVECTION OCCURS LESS FREQUENTLY THAN DURING MID SUMMER... 
THUNDERSTORMS STILL PRESENT A SEVERE WEATHER AND HEAVY RAIN THREAT. 
IRONWOOD WAS INUNDATED WITH 10.74" OF RAIN DURING SEPTEMBER 1926.
