Today is shaping up to be a gorgeous early spring day across the Northern Rockies, with temperatures running some 5 to 10 degrees above normal under high pressure. This type of flow will also bring a good push of warmer air across the region with temperatures in most locations achieving values warmer than today, despite the increased cloud cover. A variety of impacts will be possible as this cold front passes through the region. Gusts between 40 mph and 50 mph seem likely at this time, though the winds could be a bit stronger depending upon the timing of the approaching cold front. Speaking of the cold front.
UPPER TROUGH DOWN THE EASTERN SEABOARD THIS MORNING WITH DRY AIR ALOFT WRAPPING INTO THE REGION. OVERNIGHT WEAK COLD FRONT JUST MOVED OUT OF SW FL ZONES FOLLOWED BY CLEARING SKIES WHILE LOW STRATUS DECK SINKING INTO N FL ATTM. WEAK HIGH PRESSURE TO FILTER INTO THE AREA KEEPING DAYTIME TEMPS AT OR JUST BELOW CLIMO TODAY THROUGH SATURDAY.
HIGH PRESSURE WILL MOVE OVERHEAD THIS MORNING. A WEAK RIDGE OF HIGH PRESSURE WAS LOCATED OVER CENTRAL TEXAS. THE RIDGE WILL MOVE EAST TODAY AND PRESSURES HAVE BEGUN TO FALL OVER EASTERN NEW MEXICO.
LOW PRESSURE IS CENTERED OVER THE FAR SERN CORNER OF SASKATCHEWAN WITH A FRONTAL BOUNDARY EXTENDING SOUTHWARD ALONG THE ND/MT BORDER. HESITATE TO CALL IT A COLD FRONT BECAUSE TEMPERATURES ARE WARMER BEHIND THE FRONT THAN AHEAD. DRY AIR IN THE LOWER LEVELS IS KEEPING MUCH OF THE PRECIP FROM REACHING THE GROUND THOUGH THERE MAY BE ISOLATED RAIN SHOWERS EARLY THIS MORNING. SFC TEMPERATURES ARE BELOW FREEZING ACROSS PERKINS AND ZIEBACH COUNTIES EARLY THIS MORNING SO THERE REMAINS THE POSSIBILITY OF LCL LIGHT FREEZING RAIN AS THE SHOWERS MOVE THROUGH. SATURDAY WILL BE WARM AND DRY AS THE UPPER RIDGE BUILDS OVER THE HIGH PLAINS.
/issued 416 AM CST FRI MAR 4 2016/ (Today and Tonight) Winds will be from the south today 10 to 20 mph with warmer afternoon highs, mostly in the upper 70s to around 80. Lows tonight will also be warmer with lows generally in the upper 40s.

ANOTHER QUICK MOVING WEAK LOW PRESSURE SYSTEM WILL TRACK SOUTHEAST ACROSS THE GREAT LAKES AND OHIO VALLEY LATE TONIGHT AND SATURDAY BRINGING WITH IT THE CHANCES FOR RAIN AND SNOW.
A BROAD RIDGE AXIS WILL TAKE SHAPE OVER THE CENTRAL CONUS TODAY AND SATURDAY AND KEEP TEMPERATURES WARM. FIRE WEATHER CONCERNS SHOULD BE LOW EVEN WITH AFTERNOON RH VALUES IN THE LOW 20S AND UPPER TEENS IN SOME SPOTS.
416 AM CST FRI MAR 4 2016 (Today and Tonight) Winds will be from the south today 10 to 20 mph with warmer afternoon highs, mostly in the upper 70s to around 80. Lows tonight will also be warmer with lows generally in the upper 40s.
1014 AM EST FRI MAR 4 2016 HIGH PRESSURE WILL GIVE DRY WEATHER WITH COLD TEMPERATURES THIS AFTERNOON. ANOTHER AREA OF LOW PRESSURE CROSSES SATURDAY. MID MORNING UPDATE TO ADJUST POPS AS LAST BAND OF LIGHT SNOW IS INTO THE SOUTHEAST RIDGES. BUT WITH THE OVERALL TREND COOLER. THE EXCEPTION TO THIS WILL BE IN THE HIGH TERRAIN EAST. 1-3" IS POSSIBLE IN THE RIDGES OVER A 24HR PERIOD.
534 AM EST FRI MAR 4 2016 ARCTIC HIGH PRESSURE WILL CREST OVER THE AREA LATE TONIGHT INTO FRIDAY. LOW PRESSURE MOVING OFF THE MID ATLANTIC STATES WILL PASS WELL SOUTH OF THE AREA FRIDAY INTO FRIDAY NIGHT. TEMPS SHOULD RECOVER TO AFTN HIGHS ABOUT 10 DEG WARMER THAN YSTDY WITH NRN PTNS OF THE FA REMAINING MCLR. CLDS WILL BEGIN TO DECREASE ACROSS E CNTRL AND DOWNEAST PTNS OF THE FA LATE TNGT AS THE LOW TRACKS TO S OF ERN NOVA SCOTIA. WHATS LEFT OF THE SFC HI WILL CONT RIDGING ACROSS THE N TNGT ALLOWING ONE MORE NGT OF RADIATIONAL COOLING AND LOW TEMPS WELL BELOW ZERO OVR BROAD VLY AREAS. HIGH PRESSURE DOMINATES WITH SLOWLY MODERATING TEMPERATURES.
A RIDGE OF HIGH PRESSURE WILL MOVE IN FOR LATER TODAY INTO EARLY SATURDAY.
High pressure will drift southeast into the OH Valley today.
AS QUIET AND MUCH COOLER CONDITIONS HAVE SETTLED INTO THE REGION AS SFC RIDGING IS ANCHORED FROM CNTRL TX NE ACROSS THE REGION INTO THE MID MS VALLEY THIS MORNING.
NEAR CRITICAL FIRE WEATHER CONDITIONS POSSIBLE ACROSS FAR UPPER TROF MOVING ACROSS THE NORTHERN U. ROCKIES WILL SEND A DRY COLD FRONT THROUGH THE PLAINS TODAY. WHICH IS A FEW DEGREES WARMER THAN YESTERDAY. LOW LEVEL FLOW SHIFTS AROUND FROM THE EAST TO SOUTHEAST TONIGHT ACROSS THE PLAINS WHICH MAY ALLOW A SCATTERED LOW CLOUD LAYER TO DEVELOP ALONG THE LOWER EASTERN SLOPES OF THE SOUTHEAST MOUNTAINS TOWARDS SATURDAY MORNING.
612 AM CST FRI MAR 4 2016 High pressure will progress across IL today from NW to SE. Northeast areas will on the lower end of our temp range today, with around 40 for highs near Danville.
THEN CLEAR SKIES AND UPPER LEVEL RIDGING WILL DOMINATE OUR WEATHER TODAY. UPPER RIDGE WILL CONTINUE TO DOMINATE THE AREA SATURDAY AND THIS WILL ALLOW FOR CONTINUED DOWNSLOPE WARMING. LEE SIDE PRESSURE TROF WILL DEEPEN SOMEWHAT.
THIS TROUGH WILL DEVELOP INTO A COLD FRONT AND ACCELERATE SOUTHWARD LATER TODAY.
THE LOW LEVEL MOISTURE WILL SLOWLY ERODE THROUGHOUT THE DAY AND AFTER CONDITIONS IMPROVE TO VFR.
330 AM MST FRI MAR 4 2016 WARM AND DRY CONDITIONS WILL PREVAIL THROUGHOUT THE SHORT TERM PERIOD AS A LOW AMPLITUDE HIGH PRESSURE RIDGE PASSES OVER THE CENTRAL ROCKIES. DUE TO THE /DIRTY/ NATURE OF THE RIDGE. THIS WAVE MAY ALSO PRODUCE A FEW LIGHT SHOWERS OVER THE HIGHER MOUNTAINS DURING THE AFTERNOON. THE MORE INTERESTING WEATHER FEATURE WILL BE IN THE FORM OF A SIGNIFICANT PACIFIC LOW PRESSURE SYSTEM. FLOW ACROSS THE REGION VEERS TO THE SOUTHWEST ON SATURDAY NIGHT AHEAD OF A SHORT WAVE TROUGH EJECTED FROM THE DEEPER SYSTEM OFF THE WEST COAST.
A STRENGTHENING SURFACE PRESSURE TROUGH WILL ALLOW WINDS TO BECOME SUSTAINED BETWEEN 15 AND 20KTS THIS AFTERNOON OUT OF THE SOUTH-SOUTHWEST. A COLD FRONT WILL BRING NORTHERLY BUT LIGHTER WINDS EARLY SATURDAY MORNING. A SURFACE PRESSURE TROUGH WILL STRENGTHEN IN THE LEE OF THE ROCKIES WHICH WILL LEAD TO BREEZY SOUTH TO SOUTHWEST WINDS LOCALLY. ANOTHER COLD FRONT WILL BEGIN TO PUSH ITS WAY THROUGH THE REGION BEGINNING THIS EVENING.
1049 AM EST FRI MAR 4 2016 HIGH PRESSURE WILL BUILD ACROSS THE REGION TODAY. A MID/UPPER LVL TROUGH AXIS WILL CONTINUE TO SHIFT OFF THE SOUTHEAST COAST AND OVER THE WESTERN ATLANTIC IN WAKE OF DEEPENING LOW PRESSURE LIFTING TO OUR NORTHEAST. THE SETUP WILL ALLOW DRY AND COOLER HIGH PRESSURE TO BUILD OVER THE AREA THIS AFTERNOON AND A DEEP WEST/NORTHWEST DOWNSLOPING WIND TO ERODE CLOUDS FROM NORTHWEST TO SOUTHEAST AS TIME PROGRESSES INTO AFTERNOON HOURS. TEMPS SHOULD PEAK AROUND 60 DEGREES WITHIN THE TRI-COUNTY AREA AND INTO THE LOWER 60S IN SOUTHEAST GEORGIA. LOCAL CO-OP TEMP GUIDANCE SHOWS A POTENTIAL FOR MID 30S IN NORMALLY COOLER SPOTS ACROSS NORTHWEST ZONES AND WE CANNOT RULE OUT SOME PATCHY FROST IF OPTIMAL CONDITIONS ARE REALIZED.
With the passage of a cold front earlier today, temperatures will drop into the upper 50s for our northwest zones and the lower to mid 60s elsewhere by daybreak.
DEWPOINTS HAD FALLEN RATHER QUICKLY INTO THE LOWER TO MID 50S EARLIER BUT NOW HAD BUMPED UP AND STABILIZED IN THE MID 50S NORTH TO THE UPPER 50S TO NEAR 60 SOUTH. HIGH PRESSURE CONTINUES TO BUILD INTO THE AREA WITH LIGHT NORTHERLY WINDS. COLD FRONT HAS ADVANCED WELL INTO THE COASTAL WATERS. SOMEWHAT COOLER HIGH PRESSURE IN THE WAKE OF THE FRONT EXTENDS FROM SOUTHWEST TEXAS TO THE EASTERN GREAT LAKES.
HIGH PRESSURE SITS TO THE NORTHWEST TONIGHT AS THE MID LEVEL TROUGH AXIS MOVES SOUTHEAST OF THE AREA. BASED ON THE COOLER DEWPOINTS AND LESS CLOUD COVER.
748 PM EDT SAT OCT 10 2015 HIGH PRESSURE DRIFTS ACROSS THE FORECAST AREA TONIGHT THROUGH SUNDAY NIGHT.
COLD FRONT CURRENTLY SITUATED NEAR BURNS AND BAKER CITY WILL MOVE THROUGH SE OREGON THIS EVENING. WIND GUSTS TO 35 MPH ARE EXPECTED WITH THE FRONTAL PASSAGE IN SE OREGON AND THE HIGHER ELEVATIONS OF SW IDAHO. A WEAK HIGH PRESSURE RIDGE WILL BUILD IN FROM THE WEST. TEMPERATURES WILL BE 15-20 DEGREES COOLER. COLD FRONT MOVING INTO KBKE/KBNO AT 0230Z WILL MOVE THROUGH KBOI/KMYL AROUND 06Z AND KTWF/KJER AROUND 09Z.
CLEARING SKIES AND LIGHT WINDS ARE EXPECTED TONIGHT AS HIGH PRESSURE ARRIVES. COLD FRONT HAS MOVED WELL TO OUR EAST NOW WITH HIGH PRESSURE BUILDING IN FROM THE WEST AND SIGNIFICANTLY COOLER, DRIER AIR NOW WORKING ITS WAY INTO MIDDLE TENNESSEE.
835 PM MST SAT OCT 10 2015 A LOW PRESSURE SYSTEM ACROSS NORTHERN MEXICO WILL CONTINUE DRIFTING WESTWARD.
A DRY COLD FRONT WILL THEN REACH NORTHEAST NEW MEXICO SUNDAY NIGHT.
EVEN WITH WARMER OVERALL AIRMASS. INTERESTING SUNDAY EVENING AFTER THE INITIAL SURGE OF COOL AIR FILTERS IN BEHIND THE COLD FRONT. IN THAT SOME SUBTLE SURFACE RIDGING TAKES OVER WHICH WILL LIKELY DECREASE THE WINDS A BIT RELATIVELY SPEAKING. DECIDED TO HEDGE TOWARD THE WARMER GUIDANCE READINGS WITH SLIGHTLY MIXED AIR.
Winds will remain light and turn southerly before 06Z, as surface lee troughing to our north gets organized. On Sunday, as the lee troughing strengthens, south to southwest winds will increase and become gusty. /ISSUED 335 PM CDT SAT OCT 10 2015/ (Tonight and Sunday) Expect hot and dry conditions on Sunday due to a low level thermal ridge and gusty southwest winds. The high temperatures will be 10 to 15 degrees above normal. Upper level ridge over the West Coast will create dry northwest flow across the southern plains.
AS WELL AS OVER OFFSHORE GULF OF MEXICO WATERS NORTHWEST OF THE LOWER KEYS. TEMPERATURES ARE IN THE LOWER TO MID 80S. AN AREA OF LOW PRESSURE WILL BE LOCATED NEAR THE SOUTHEAST COAST OF THE UNITED STATES OVERNIGHT.
/ISSUED 352 PM CDT SAT OCT 10 2015/ Hot ridge builds into northeast Oklahoma and northwest Arkansas on Sunday.
LEE TROUGHING AND LOW-LEVEL THERMAL RIDGING WILL INCREASE BY SUNDAY.
THEN TEMPERATURES WILL BE WARMER THAN CURRENTLY FORECAST.
/ISSUED 352 PM EDT SAT OCT 10 2015/ A PRE-FRONTAL TROUGH OF LOW PRESSURE WAS LOCATED OVER LAKE OKEECHOBEE EARLY THIS AFTERNOON WITH A COLD FRONT LOCATED OVER NORTHERN FLORIDA. THE PRE-FRONTAL TROUGH WILL MOVE EAST INTO THE WESTERN ATLANTIC WATERS TONIGHT. AS THE COLD FRONT MOVES SOUTHWARD INTO CENTRAL FLORIDA.
703 PM EDT SAT OCT 10 2015 HIGH PRESSURE OVER THE REGION WILL MOVE EAST OF NEW ENGLAND BY SUNDAY. THE RESULT WILL BE CONTINUED DRY CONDITIONS ALONG WITH MARKEDLY WARMER TEMPERATURES.
HIGH CLOUDS AND LOCALLY BREEZY CONDITIONS OVER THE HIGHER ELEVATIONS OF THE SIERRA THIS WEEKEND.
A LOW PRESSURE SYSTEM TO THE SOUTH MAY BRING A CHANCE OF SHOWERS TO THE AREA FOR MUCH OF THE WEEK ALONG WITH A WARM AND HUMID WEATHER PATTERN. ANOTHER WARM DAY FOR THE SOUTHLAND BUT COOLER FOR THE CENTRAL COAST. HIGH PRESSURE IN PLACE OVER THE REGION WILL START TO WEAKEN OVER THE NEXT SEVERAL DAYS AS A TROUGH OF LOW PRESSURE TO THE SOUTH OF THE AREA MOVES NORTH. HUMIDITY WILL BE A DIFFERENT STORY THOUGH AS SUBTROPICAL MOISTURE WILL BE EMBEDDED IN THE TROUGH OF LOW PRESSURE.
THE FRONTAL TROUGH WILL BECOME STATIONARY ACROSS SOUTHERN PENINSULA. THE OVERALL REDUCTION IN MOISTURE WILL LOWER RAIN CHANCES COMPARED TO SAT BUT COOLER TEMPERATURES ALOFT (AROUND -8C) WILL COMBINE WITH SFC HEATING AND A SEA BREEZE BOUNDARY TO PRODUCE ISOLATED STORMS DURING THE AFTN.
1159 PM EDT SAT OCT 10 2015 HIGH PRESSURE WILL MOVE SOUTH OF THE REGION TONIGHT THROUGH SUNDAY.
NAM MOS GUIDANCE FOR MCCOOK CAME IN 6 DEGREES WARMER AT AN EVEN 100. WITH COMPRESSIONAL WESTERN COMPONENT WINDS DEVELOPING AHEAD OF APPROACHING COLD FRONT. NOT SURE IF WILL MATTER IN THE END BUT IT MAY TAKE A COUPLE DEGREES OFF TEMPERATURES IN SOME AREAS IF THE LOW LEVEL MOISTURE DOES REMAIN HIGHER. A FIRE NOT TO MENTION AN APPROACHING COLD FRONT IN THE EVENING SHIFTING WINDS. COOLER AIR WILL BE ON THE DOOR STEP BY SUNSET SUNDAY AND PROBABLY ALREADY MOVING INTO THE NORTHERN PART OF THE FORECAST AREA AROUND ORD AND GREELEY.
827 PM EDT SAT OCT 10 2015 CURRENT SURFACE ANALYSIS SHOWS A COLD FRONT OVER NE FL PUSHING TO THE SOUTHEAST. 500 MB ANALYSIS SHOWS AN INTENSIFYING LOW PRESSURE SYSTEM OVER THE CAROLINAS MOVING TO THE SOUTHEAST. AS THIS LOW PUSHES SLOWLY TO THE EAST EXPECT LOW LEVEL MOISTURE TO WRAP AROUND THE BACKSIDE OF THE LOW AND PRODUCE INCREASING LOW STRATUS CLOUDS OVER THE NORTHERN PART OF THE CWA EARLY TOMORROW MORNING. CLEARING SKIES OVER MOST OF THE AREA AND A COOLER AIR MASS BEHIND THE FRONT WILL ALLOW US TO DROP INTO THE LOW TO MID 60S OVER GA AND NORTHERNMOST FLORIDA. PREVAILING VFR AT LEAST FOR THE NEXT SEVERAL HOURS UNTIL COLD FRONT PUSHES SWD WITH A CORRESPONDING INCREASING IN LOW CLOUD POTENTIAL THROUGH SUNDAY MORNING.
AS THE TROUGH APPROACHES ON SUNDAY THE GRADIENT WILL TIGHTEN AND SURFACE WINDS WILL INCREASE ESPECIALLY ALONG THE WYOMING BORDER.
716 PM EDT SAT OCT 10 2015 HIGH PRESSURE BUILDS SOUTH OF NEW ENGLAND TONIGHT AND SUNDAY.
THE AFOREMENTIONED SOLUTIONS DEPICT STRONG POST FRONTAL WESTERLY WINDS DEVELOPING BEHIND A COLD FRONT THAT WILL PROPAGATE THROUGH THE AREA BY MIDDAY SUNDAY. TRANSFER OF THIS HIGH MOMENTUM AIR SHOULD EASILY BE ACHIEVED. SELFRIDGE.
805 PM EDT SAT OCT 10 2015 DEWPOINTS CURRENTLY RANGE FROM THE LOW TO MID 40S IN OUR NORTHERN COUNTIES TO THE LOW 50S OVER OUR SOUTHEAST COUNTIES. EASTERN KY WILL BE MEET WITH CLEARING SKIES AND COOL TEMPS OVERNIGHT WITH DECENT 5 DEGREE OR SO RIDGE/VALLEY SPLIT. WITH TEMPS DROPPING INTO THE LOWER 40S AND EVEN A FEW UPPER 30S IN THE VALLEYS. AS HIGH PRESSURE BUILDS ACROSS THE OH AND TN VALLEYS. GIVEN THAT THE CLOUD COVER HAS BEEN MORE ROBUST OVERALL KEEPING DEW POINTS A BIT ON THE HIGH SIDE. UPPER LEVEL RIDGING AND HIGH PRESSURE WILL BUILD INTO THE AREA BRINGING MOSTLY SUNNY AND CALM CONDITIONS ACROSS THE REGION. MODELS REMAIN IN GOOD AGREEMENT WITH HIGH PRESSURE MOVING SE OF THE REGION SUNDAY NIGHT AHEAD OF A WEAK COLD FRONT.
COLD FRONT HAS MOVED WELL TO OUR EAST NOW WITH HIGH PRESSURE BUILDING IN FROM THE WEST AND SIGNIFICANTLY COOLER, DRIER AIR NOW WORKING ITS WAY INTO MIDDLE TENNESSEE.
A LOW PRESSURE SYSTEM CURRENTLY LOCATED OVER THE BAJA PENINSULA WILL MOVE WEST OUT OVER THE PACIFIC WATERS AND MAY BE A FACTOR IN OUR WEATHER BY MIDWEEK. THIS SEEMS REASONABLE GIVEN THE LINGERING CLOUDS AND THE LATEST MODEL GUIDANCE SHOWS RATHER HIGH MOISTURE CONTENT IN THE LOW LEVEL. BUT TEMPS WILL BE SLIGHTLY COOLER THAN TODAY.
COLD FRONT HAS ADVANCED WELL INTO THE COASTAL WATERS. SOMEWHAT COOLER HIGH PRESSURE IN THE WAKE OF THE FRONT EXTENDS FROM SOUTHWEST TEXAS TO THE EASTERN GREAT LAKES.
THIS EVENING THROUGH SUNDAY NIGHT UPPER RIDGING IS DOMINATING THE CENTRAL CONUS WITH THE MAIN RIDGE ACROSS THE DAKOTAS. A STRONG COLD FRONT WILL ENTER THE NWRN PTNS OF THE CWA LATE SUN MRNG. BUT GENERALLY BEHIND THE FRONT ACROSS NE WY/NW SD TEMPS WILL REACH THE LOW 70S.
Upper level ridging will remain in place through the short term period. At the surface an elongated area of high pressure will slowly slide across the region through Sunday night. With high pressure over the region bringing mostly clear skies and light winds, conditions will be good for radiational cooling. Temperatures are expected to fall into the lower to mid 40s. Highs tomorrow will be warmer than today, topping out in the lower to mid 70s.
AN UPPER LEVEL LOW WILL TRACK FROM GEORGIA TO THE CAROLINA COAST TONIGHT.
A LIGHT NORTH WIND WILL PERSIST IN THE WAKE OF A COLD FRONT MOVING SOUTH OVER THE GULF OF MEXICO. AS AN UPPER LOW BECOMES APPOSED TO THE GA/NC/SC ATLANTIC SEABOARD. GUIDANCE IS PRETTY CONSISTENT IN ADVERTISING ANY SIGNIFICANTLY COOLER TEMPS BEING REALIZED TO THE EAST OF THE AREA.
UPPER LEVEL RIDGE WILL BUILD OVER THE REGION FOR SUNDAY LEADING TO ABOVE NORMAL TEMPERATURES AND MAINTAIN DRY CONDITIONS.
909 PM EDT SAT OCT 10 2015 WATER VAPOR SATELLITE IMAGERY AND REGIONAL 00Z SOUNDINGS ARE SHOWING DRIER AIR MOVING INTO THE STATE AS A COLD FRONT MOVES SOUTHEAST THROUGH THE REGION. HIGH PRESSURE BUILDING INTO THE WESTERN GULF WILL EXPAND INTO THE COASTAL WATERS THROUGH THE END OF THE WEEKEND.
751 PM EDT SAT OCT 10 2015 HIGH PRESSURE WILL SETTLE ACROSS THE OHIO VALLEY TONIGHT ALLOWING FOR A COLD START TOMORROW MORNING. THE HIGH WILL THEN MOVE EAST OF THE REGION ON SUNDAY.
A RIDGE AXIS REACHED FROM TX TO THE OHIO RIVER VALLEY WITH A RESULTING LOW LEVEL SW FLOW OVER IA AND IL. A RIDGE AXIS WAS CENTERED OVER THE NORTHERN ROCKIES WITH A DOWNSTREAM NW FLOW ACROSS THE MIDWEST AND OHIO VALLEY TO LOW PRESSURE OVER THE MID ATLANTIC. UNDER THIS RIDGE THERE WAS A LARGE AREA OF 20 PLUS C TEMPERATURES AT 850 MB OVER THE NORTHERN ROCKIES AND NORTHERN PLAINS. HOLDING TEMPERATURES MUCH WARMER THAN LAST NIGHT. THE DRY AIR AND AMBIENT CONDITIONS BACK GUIDANCE LOWS FROM AROUND 50 TO THE LOWER 50S. THE SURFACE PRESSURE GRADIENT TIGHTENS CONSIDERABLY AHEAD OF THE DEEPENING TROUGH UPSTREAM IN THE PLAINS. EVEN PARTIALLY TAPPING INTO THIS BY MIXING TO 900 MB WOULD PUSH TEMPERATURES INTO THE LOWER TO MID 80S.
AN UPPER LEVEL RIDGE OF HIGH PRESSURE OVER THE NORTHERN PLAINS AND CANADA WILL SHIFT INTO THE WESTERN GREAT LAKES REGION BY SUNDAY MORNING. SCATTERED/BROKEN CIRRUS ON THE EASTERN SIDE OF THE RIDGE WILL CONTINUE TO MOVE THROUGH THE NORTHLAND THROUGH AT LEAST LATE THIS EVENING. SO LEANED ON THE SLIGHTLY WARMER THAN AVERAGE MODEL GUIDANCE FOR OVERNIGHT LOW TEMPERATURES. THE LOWER LEVEL THERMAL RIDGE WILL BUILD INTO THE NORTHLAND FROM THE WEST AND SOUTH SUNDAY. THE AMOUNT OF SUNSHINE FOR A MIDDLE OCTOBER DAY WILL NOT LIKELY BE ABLE TO RESULT IN ENOUGH SURFACE HEATING TO ALLOW THE LOWER LEVELS TO MIX OUT WELL AND TAP INTO THE MUCH WINDIER AND WARMER AIR ALOFT. A LOW PRESSURE SYSTEM WILL PASS THROUGH SOUTHERN PORTIONS OF MANITOBA INTO NORTHWEST ONTARIO SUNDAY NIGHT.
1022 PM EDT SAT OCT 10 2015 HIGH PRESSURE OVER THE REGION WILL MOVE EAST OF NEW ENGLAND BY SUNDAY. THE RESULT WILL BE CONTINUED DRY CONDITIONS ALONG WITH MARKEDLY WARMER TEMPERATURES.
940 PM EDT SAT OCT 10 2015 A FEW SHOWERS STILL CIRCULATING OVER NORTH GA AROUND THE UPPER LOW AS IT MOVES SLOWLY ACROSS THE CAROLINAS. 41 MODELS INITIALIZE WELL AT 18Z WITH THE UPPER LOW CURRENTLY SPINNING ACROSS NORTHEAST GA.
In addition, southerly winds at 10 to 14 kts result in highs from the lower 90s over north central areas, to the mid and upper 80s over east central and northeast KS. Elsewhere, minimum RH in the low to mid 30s is likely.
Warmer readings are expected to the west, with middle 50s near Joplin and Pittsburg.
949 PM EDT SAT OCT 10 2015 THE NEAR TERM SECTION HAS BEEN UPDATED BELOW DRY WEATHER IS EXPECTED THROUGH THE REST OF THE WEEKEND AS STRONG HIGH PRESSURE OVER ILLINOIS SLOWLY DEPARTS TO THE EAST.
1052 PM EDT SAT OCT 10 2015 HIGH PRESSURE WILL SETTLE ACROSS THE OHIO VALLEY TONIGHT ALLOWING FOR A COLD START TOMORROW MORNING. THE HIGH WILL THEN MOVE EAST OF THE REGION ON SUNDAY.
A WEAK UPPER LEVEL RIDGE WILL CROSS THE AREA SUNDAY FOR DRY WEATHER AND A LITTLE AFTERNOON SUNSHINE.
710 PM PDT SAT OCT 10 2015 HIGH PRESSURE WILL GRADUALLY WEAKEN.
800 PM EDT SAT OCT 10 2015 HIGH PRESSURE OVER THE REGION WILL MOVE EAST OF NEW ENGLAND BY SUNDAY. THE RESULT WILL BE CONTINUED DRY CONDITIONS ALONG WITH MARKEDLY WARMER TEMPERATURES.
A COLD FRONT IS MOVING INTO THE BLUE MOUNTAINS THIS EVENING. EXPECT WINDS TO SUBSIDE IN 2-3 HOURS WITH HIGHER WINDS PERSISTING AT RIDGETOPS.
MOST LOCATIONS SHOULD BE SOME 10 TO 15 DEGREES WARMER. MOST RECORD HIGHS FOR OCTOBER 11TH ARE IN THE LOWER TO MIDDLE 80S.
THE LOW CONDITIONS WILL CLEAR BACK OFFSHORE EARLY SUNDAY MORNING. A COLD FRONT IS NOW MOVING ONSHORE.
AS HIGH PRESSURE CENTER SHIFTS FROM ARKANSAS INTO ALABAMA. THIS WILL RESULT IN FALL LIKE TEMPS TONIGHT AS SFC RIDGING BUILDS OVERHEAD.
654 PM CDT SAT OCT 10 2015 WAA WILL CONTINUE THROUGH THE OVERNIGHT INTO SUNDAY MORNING AND IS ANTICIPATED TO KEEP TEMPERATURES IN THE LOWER TO MIDDLE 50S ACROSS CENTRAL IOWA. LEANED TOWARD THE WARMER GFS/ECMWF FOR LOWS. LARGE RIDGE WILL PERSIST ACROSS MIDWEST THROUGH THE END OF THE WEEKEND ALLOWING FOR WELL ABOVE NORMAL TEMPERATURES ACROSS THE AREA. AND HAVE KEPT FORECAST TEMPS IN THE LOW TO MID 80S.
THIS AFTERNOON AND TONIGHT HIGH PRESSURE WILL SETTLE SOUTHWARD LATE TODAY INTO TONIGHT AS WEAK POSITIVE TILTED UPPER TROUGH SHIFTS THROUGH THE NEW ENGLAND STATES INTO THE NORTHERN ATLANTIC OCEAN. THIS WILL ALLOW A DECENT PRESSURE GRADIENT TO DEVELOP WITH TIME TONIGHT BETWEEN THIS DEPARTING HIGH PRESSURE AND DEVELOPING LOW PRESSURE OVER THE CANADIAN PRAIRIE PROVINCES. SUNDAY THROUGH SATURDAY THE UPCOMING WEEK WILL BE FAIRLY QUIET WEATHER WISE AS A LACK OF MOISTURE CONTENT PREVENTS A SERIES OF COLD FRONTS FROM DOING MUCH OUTSIDE OF PRODUCING CLOUDS AND DROPPING TEMPS.
Spectacular fall weather will continue through the weekend as high pressure prevails. The high will pass through the area tonight. A few degrees cooler and frost would be a concern, but we think that should not be the case at least for tonight.
HOWEVER A DEGREE OR TWO OF COOLING IS LIKELY OVER THE FAR NORTH AS A WEAK PUSH OF COOLER AIR ARRIVES LATE IN THE DAY. SLIGHTLY COOLER AIR ACROSS THE NORTHERN AND CENTRAL PORTION OF THE FORECAST AREA WILL CAUSE LOWS TO FALL A FEW DEGREES BUT READINGS SHOULD STAY ABOVE NORMAL. DURING THIS TIME PERIOD AND ANOMALOUSLY STRONG LOW PRESSURE SYSTEM TAKES HOLD OF EASTERN NOAM. BLOCKING THE UPSTREAM FEATURES BACK TO THE EASTERN PACIFIC. THIS INCLUDES A CUT OFF LOW THAT WILL SLOWLY ROTATE CLOCKWISE AROUND A STRONG RIDGE CENTERED OVER THE NORTHERN MEXICO DESERTS.
Dry conditions are expected to continue despite a series of cold fronts moving through the region.
639 PM CDT SAT OCT 10 2015 HIGH PRESSURE HAS SETTLED IN AND VFR CONDITIONS ARE EXPECTED FOR THIS TAF PERIOD AT ALL TERMINALS.
as ridging dominates the central part of the country. /ISSUED 352 PM CDT SAT OCT 10 2015/ Hot ridge builds into northeast Oklahoma and northwest Arkansas on Sunday.
DRY WEATHER IS EXPECTED THROUGH THE REST OF THE WEEKEND AS STRONG HIGH PRESSURE OVER ILLINOIS SLOWLY DEPARTS TO THE EAST.
740 PM EDT SAT OCT 10 2015 MODELS INITIALIZE WELL AT 18Z WITH THE UPPER LOW CURRENTLY SPINNING ACROSS NORTHEAST GA.
917 PM CDT SAT OCT 10 2015 COOL AND DRY HIGH PRESSURE SETTLING ACROSS THE REGION TONIGHT TO ALLOW FOR LOW TEMPERATURES TO FALL INTO THE UPPER 40S ACROSS PORTIONS OF SE OKLAHOMA. AND NORTH CENTRAL LOUISIANA TO THE LOWER 50S ACROSS THE REMAINDER OF THE FOUR STATE REGION.
LATEST WATER VAPOR AND 500 MB HEIGHTS SHOWS THE CLOSED LOW THAT WAS RESPONSIBLE FOR THE ACTIVE WEATHER YESTERDAY HEADING FURTHER WEST INTO THE PACIFIC WHILE THE ANTICYCLONIC FLOW BEGINS TO ESTABLISH ACROSS THE TEXAS REGION. AS THIS RIDGE BUILDS TODAY AND TOMORROW THE CHANCES OF RAIN BECOME VERY LIMITED. DEWPOINTS WILL REMAIN IN THE LOW 70S WHICH WILL BE CLOSE TO THE LOW TEMPERATURES EXPECTED TONIGHT.
511 PM MDT SAT OCT 10 2015 EARLY AFTERNOON SATELLITE AND RAP UPPER LEVEL ANALYSIS SHOWS RIDGE EXTENDING FROM MEXICO ACROSS EH SOUTHERN PLAINS AND CENTRAL ROCKIES. WARMER END OF GUIDANCE NOW SUPPORTS HIGHS 95 (GOODLAND) TO 100F (MCCOOK) WHICH WOULD BE ABOVE MONTHLY RECORDS FOR MOST LOCATIONS IN OUR CWA. TEMPS ALOFT SEEM TO SUPPORT THE LOWER END OF THIS SPECTRUM AND MODEL CONSENSUS. UPPER FLOW WILL BE WESTERLY SUNDAY NIGHT ACROSS THE CENTRAL PLAINS AS A TROUGH MOVES EAST ACROSS THE NORTHERN PLAINS.
703 PM EDT SAT OCT 10 2015 A COLD FRONT WILL MOVE THROUGH THE AREA THIS EVENING BRINGING SHOWERS AND A FEW THUNDERSTORMS. ANOTHER COLD FRONT.
