633 AM EDT SAT AUG 22 2015 A STATIONARY FRONT WILL REMAIN JUST OFFSHORE TODAY AS HIGH PRESSURE BUILDS IN FROM THE WEST. LOW PRESSURE PASSES THROUGH THE WESTERN ATLANTIC WATERS THIS WEEKEND.
UPPER LEVEL RIDGE WILL CONTINUE OVER THE EASTERN GULF TONIGHT. SHORT WAVES LIFTING NORTHEAST AROUND THIS RIDGE WILL CONTINUE TO KEEP SOME WEAK LIFT ACROSS THE REGION TONIGHT. OVERNIGHT LOWS WILL BE IN THE LOWER 70S. WITH A TROUGH LINGERING OVER THE AREA THE POSSIBILITY FOR SHOWERS AND THUNDERSTORMS WILL BE ON THE INCREASE. USED THE GUIDANCE CONSENSUS FOR THE HIGH TEMPERATURE FORECAST AND WARMER GUIDANCE FOR THE LOW TEMPERATURE BECAUSE OF THE RECENT BIAS AND MOIST AIR MASS. MOISTURE ASSOCIATED WITH THE REMNANTS OF THE TROUGH AND ASSOCIATED FRONT SHOULD CONTINUE TO AFFECT THE AREA THROUGH SUNDAY NIGHT.
412 AM CDT SAT AUG 22 2015 STRONG COLD FRONT CONTINUES TO ADVANCE EASTWARD AND IS NOW INTO THE WESTERN DAKOTAS. AS THE UPPER LOW ROTATES EASTWARD OVER THE AREA THIS EVENING.
LATEST AVAILABLE IR IMAGERY OVERLAID WITH AVAILABLE MODEL STREAMLINE ANALYSIS AS OF 200 AM DEPICTS THE CENTER OF A REGIONAL SCALE ANTICYCLONE SITUATED NEAR DAYTONA BEACH. AT THE SURFACE AND THE LOWER LEVELS. VERY WEAK AND BROAD RIDGING IS EVIDENT ACROSS THE KEYS. LAST EVENINGS SOUNDING REMAINED EXCEPTIONALLY MOIST IN THE LOWER TO MID TROPOSPHERE WITH GENTLE NORTHEASTERLIES FROM OFF OF THE SURFACE UP TO 400 MB.
226 AM EDT SAT AUG 22 2015 HIGH PRESSURE WILL DOMINATE OUR WEATHER THROUGH SUNDAY.
147 AM EDT SAT AUG 22 2015 HIGH PRESSURE WILL BRING SEASONABLE AND PLEASANT WEATHER FOR THE WEEKEND.
1041 PM PDT FRI AUG 21 2015 Low pressure exits and high pressure starts to build in. The cooler air and lighter winds on Saturday should help regional firefighting efforts, but the light winds and strong morning inversions this weekend may create areas of poor air quality due to high concentrations of wildfire smoke. Overall, however, it looks like some of the northeast valleys could become rather chilly with some areas dropping into the lower 40s to upper 30s in sheltered valleys. Cote' 06Z TAFS: High pressure will start to build in as low pressure moves east.
110 AM EDT SAT AUG 22 2015 HIGH PRESSURE WILL START TO BUILD OVER THE REGION RESULTING IN DRIER AND COOLER WEATHER THAN THE LAST FEW DAYS. COOLER AND DRIER WEATHER WILL LAST THOUGH THE WEEKEND.
102 AM EDT SAT AUG 22 2015 HIGH PRESSURE BEGINS TO BUILD EAST FROM OHIO TONIGHT.
128 AM EDT SAT AUG 22 2015 HIGH PRESSURE BUILDS IN FROM THE WEST AS LOW PRESSURE PASSES THROUGH THE WESTERN ATLANTIC WATERS THIS WEEKEND.
532 AM EDT SAT AUG 22 2015 HIGH PRESSURE IS EXPECTED TO BRING DRY WEATHER AND SEASONAL TEMPERATURES THROUGH THE WEEKEND. HIGH PRESSURE CENTERED OVER THE REGION IS EXPECTED TO KEEP SKIES MAINLY CLEAR. HIGH PRESSURE SHOULD GRADUALLY SLIDE EAST THROUGH SUNDAY.
641 AM EDT SAT AUG 22 2015 HIGH PRESSURE WILL CONTINUE TO EXTEND ACROSS THE AREA THROUGH TONIGHT. A COLD FRONT WILL MOVE ACROSS THE REGION SUNDAY AFTERNOON AND EVENING. HIGH PRESSURE CENTERED OVER WESTERN NEW YORK WILL CONTINUE TO SLOWLY MOVE EAST. BUT RIDGING EXTENDING SOUTHWEST FROM THE CENTER WILL REMAIN ACROSS THE FORECAST AREA. HIGHS SHOULD BE A FEW DEGREES WARMER THAN YESTERDAYS READINGS. THIS WILL CAUSE A COLD FRONT TO SWEEP ACROSS THE REGION SUNDAY AFTERNOON AND EVENING. A WEAK SHORT WAVE OUT AHEAD OF THE PRIMARY UPPER TROUGH AXIS WILL PROVIDE SOME EXTRA LIFT AHEAD OF THE FRONT WITH MOST OF THE STRONGER DYNAMICS BEHIND THE BOUNDARY AND LIFTING NORTHEAST AWAY FROM THE AREA.
FALL-LIKE WEATHER WILL CONTINUE TODAY AS HIGH PRESSURE CENTERED OVER WESTERN PA CONTINUES TO RIDGE DOWN THE OHIO VALLEY. BY TONIGHT THE HIGH WILL HAVE RETREATED TO THE EAST, AND WE'LL MOISTEN UP IN THE SOUTHERLY FLOW AHEAD OF AN APPROACHING COLD FRONT. CHANCES AND TIMING OF PRECIP ARE THE MAIN QUESTION IN THIS FORECAST, AS THE COLD FRONT WILL STILL PUSH THROUGH LATE SUNDAY EVEN AS THE UPPER LOW CLOSES OFF OVER FAR WESTERN ONTARIO.
336 AM CDT SAT AUG 22 2015 Models continue to show an upper level trof moving across the middle Mississippi/lower Ohio River valleys today. Dry conditions are expected this evening, then models show a cold front reaching far western portions of the PAH forecast area by 12z Sunday.
1219 AM CDT SAT AUG 22 2015 AN UPPER LEVEL TROUGH WILL APPROACH FROM THE WEST OVERNIGHT INTO SAT. BETTER CHANCES FOR MORE WIDESPREAD PRECIP WILL COME JUST BEYOND THIS TAF PERIOD AS A COLD FRONT DROPS SOUTH INTO THE REGION.
315 AM MST SAT AUG 22 2015 THUNDERSTORMS WILL BE MOST COMMON IN THE HIGHER TERRAIN OF SOUTHERN AND EASTERN ARIZONA TODAY. HIGH PRESSURE WILL SETTLE FURTHER EAST ACROSS THE FOUR CORNERS BY SUNDAY NIGHT.
MEANWHILE A FAIRLY STRONG LOW PRESSURE AREA WILL TRACK FROM WRN SD INTO WRN ONTARIO CANADA AS A STRONG UPPER TROUGH MOVES FROM MT TO THE UPPER MS RIVER VALLEY. THE LOW PRESSURE AREA WILL INCREASE THE PRESSURE GRADIENT SUFFICIENTLY FOR BREEZY SSELY WINDS TODAY. 925 MB TEMPS AROUND 20C AND FAIRLY LOW RELATIVE HUMIDITY WILL BOOST HIGH TEMPS INTO THE LOWER 80S ONCE AGAIN WITH SLIGHTLY COOLER CONDITIONS OVER FAR ERN WI VIA THE LAKE BREEZE. A SVR LINE OF CONVECTION IS EXPECTED OVER MN AND IA DURING THE EVENING JUST AHEAD OF THE COLD FRONT AND APPROACHING UPPER TROUGH. MOIST ADVECTION JUST AHEAD OF THE COLD FRONT.
A RIDGE OF HIGH PRESSURE WILL BUILD OVER THE REGION ON SATURDAY.
422 AM EDT SAT AUG 22 2015 HIGH PRESSURE WILL CONTINUE TO EXTEND ACROSS THE AREA THROUGH TONIGHT. A COLD FRONT WILL MOVE ACROSS THE REGION SUNDAY AFTERNOON AND EVENING. HIGH PRESSURE CENTERED OVER WESTERN NEW YORK WILL CONTINUE TO SLOWLY MOVE EAST. BUT RIDGING EXTENDING SOUTHWEST FROM THE CENTER WILL REMAIN ACROSS THE FORECAST AREA. HIGHS SHOULD BE A FEW DEGREES WARMER THAN YESTERDAYS READINGS. THIS WILL CAUSE A COLD FRONT TO SWEEP ACROSS THE REGION SUNDAY AFTERNOON AND EVENING. A WEAK SHORT WAVE OUT AHEAD OF THE PRIMARY UPPER TROUGH AXIS WILL PROVIDE SOME EXTRA LIFT AHEAD OF THE FRONT WITH MOST OF THE STRONGER DYNAMICS BEHIND THE BOUNDARY AND LIFTING NORTHEAST AWAY FROM THE AREA.
HOWEVER THE INFLUENCE OF THIS LARGE HIGH PRESSURE SYSTEM WILL REMAIN STRONG ENOUGH TO KEEP DRY AND QUIET WEATHER ACROSS THE REGION THROUGH THE DAY. WITH TEMPS RISING SLIGHTLY FROM YESTERDAY TO THE LOW AND MID 80S. AN UPPER LEVEL LOW WILL DEEPEN THROUGH THE DAY TODAY AS IT MOVES EASTWARD ACROSS THE NORTHERN CONUS. THIS COLD FRONT WILL HAVE SHIFTED EASTWARD. NEARING THE LOWER MISSISSIPPI VALLEY. ESPECIALLY AS THE COLD FRONT CONTINUES TO SHIFT EASTWARD INTO THE REGION THROUGHOUT THE DAY. THE MODELS ARE IN PRETTY GOOD AGREEMENT ALOFT WITH A UNSEASONABLY DEEP TROUGH CROSSING THE GREAT LAKES EARLY IN THE EXTENDED.
As forcing associated with the upper trough pushes east, the whole area of convection will follow as the cold front pushes to the southeast. The low level jet will strengthen as the sun sets and this will enhance the low level shear and helicity for for storms to work with. Much cooler and drier air will move into the area in the wake of the cold front. The next chance for precipitation may then come by the end of the week as the upper ridge flattens out over the west.
128 AM EDT SAT AUG 22 2015 HIGH PRESSURE WILL SETTLE OVERHEAD THROUGH THIS MORNING. MOISTURE SHOULD RETURN AHEAD OF AN APPROACHING COLD FRONT THIS WEEKEND.
530 AM EDT SAT AUG 22 2015 HIGH PRESSURE WILL DOMINATE OUR WEATHER THROUGH SUNDAY.
200 AM EDT SAT AUG 22 2015 HIGH PRESSURE CURRENTLY CENTERED OVER THE OHIO VALLEY WILL SHIFT EASTWARD OVER THE WEEKEND. THIS WILL OPEN THE DOOR FOR A COLD FRONT LATE SUNDAY WHICH WILL BRING SOME STORMS BACK TO THE AREA. HIGH PRESSURE IS DOMINATING THE AREA. MEANWHILE A REASONABLY STRONG MID/UPPER LEVEL TROUGH WILL MOVE OUT OF THE NORTHERN ROCKIES AND OVER THE UPPER LAKES SUNDAY. THE SHARP COLD FRONT THAT WILL MOVE INTO THE REGION LATE SUNDAY/SUNDAY NIGHT WILL BE SUFFICIENT TO TRIGGER SOME STORMS. THE WIND FIELDS WILL BE PEAKING AFTER 00Z ASSOCIATED WITH THE MID LEVEL TROUGH. DEW POINTS IN THE LOW 50S.
DRY UPPER RIDGE WILL QUICKLY REBUILD OVER THE FORECAST AREA THIS WEEKEND. TEMPERATURES TODAY WILL BE ABOUT 5 DEGREES BELOW NORMAL IN THE WAKE OF YESTERDAYS TROUGH PASSAGE.
221 AM EDT SAT AUG 22 2015 HIGH PRESSURE WILL DOMINATE OUR WEATHER THROUGH SUNDAY.
ANOTHER COLD FRONT IS EXPECTED TO DROP INTO THE LOWER MISSISSIPPI VALLEY SUNDAY AFTERNOON INTO SUNDAY NIGHT.
245 AM EDT SAT AUG 22 2015 HIGH PRESSURE IS EXPECTED TO BRING DRY WEATHER AND SEASONAL TEMPERATURES THROUGH THE WEEKEND. HIGH PRESSURE CENTERED OVER THE REGION IS EXPECTED TO KEEP SKIES MAINLY CLEAR. HIGH PRESSURE SHOULD GRADUALLY SLIDE EAST THROUGH SUNDAY.
416 AM EDT SAT AUG 22 2015 A COLD FRONT WILL CROSS THE REGION AND STALL ACROSS DOWNEAST MAINE THIS AFTERNOON WHILE HIGH PRESSURE BUILDS IN BRIEFLY ACROSS THE NORTHERN AREAS.

313 AM CDT SAT AUG 22 2015 06Z SFC DATA HAD HIGH PRESSURE OVER THE EASTERN GREAT LAKES WITH SOUTHERLY FLOW ACROSS THE PLAINS. A STRONG LOW PRESSURE WAS OVER WESTERN SOUTH DAKOTA. AS THE COLD FRONT MOVES INTO THE WESTERN PARTS OF MINNESOTA AND IOWA LATE THIS AFTERNOON. THE LINE OF STORMS ALONG THE APPROACHING COLD FRONT SHOULD BEGIN MOVING INTO THE FAR WESTERN AREAS SHORTLY AFTER SUNSET AND PROGRESS EASTWARD ACROSS THE AREA OVERNIGHT. HIGHS SHOULD STRUGGLE TO REACH THE LOWER TO MID 70S.
415 AM EDT SAT AUG 22 2015 HIGH PRESSURE CURRENTLY CENTERED OVER THE OHIO VALLEY WILL SHIFT EASTWARD OVER THE WEEKEND. A COLD FRONT WILL MOVE THROUGH THE AREA LATE SUNDAY. HIGH PRESSURE WILL GRADUALLY FILL BACK IN ACROSS THE REGION THROUGH THE REST OF THE WEEK. HIGH PRESSURE CONTINUES TO CONTROL THE LOCAL WEATHER. SUNDAY WILL BE A FEW DEGREES WARMER THAN SATURDAY AS SOUTH TO SOUTHWEST FLOW INCREASES AHEAD OF A COLD FRONT. THE COLD FRONT WILL MOVE ACROSS THE REGION LATE SUNDAY AFTERNOON/NIGHT AS THE HIGH SHIFTS NE INTO NEW YORK. MOST OF SUNDAY WILL BE DRY WITH A FAIR AMOUNT OF DRY AIR LINGERING BEHIND THE HIGH. DEW POINTS WILL ONLY GET INTO THE LOW 60S BY MID TO LATE AFTERNOON. BEHIND THE FRONT TEMPERATURES FALL BACK INTO THE 70S AND DEW POINTS DROP INTO THE LOW 50S.
339 AM EDT SAT AUG 22 2015 DRY CONDITIONS WILL PREVAIL INTO EARLY SUNDAY AS HIGH PRESSURE MOVES EAST OF THE REGION. THE CHANCE OF SHOWERS AND THUNDERSTORMS WILL ACCOMPANY A COLD FRONT AS IT SWEEPS ACROSS THE AREA SUNDAY. CLOSED UPPER LOW WILL BE LOCATED IN NORTHERN MINNESOTA TOWARDS THE END OF THE PERIOD WITH A COLD FRONT DRAPED SOUTH INTO EASTERN IOWA. NARROW PLUME OF MOISTURE WILL MOVE NORTH ON SUNDAY IMMEDIATELY AHEAD OF FRONT AS NOSE OF THETA E RIDGE AND PWATS OF 1.
LATEST SATELLITE IMAGERY SHOWS UPPER LEVEL LOW DROPPING FROM BRITISH COLUMBIA INTO NORTHWEST MONTANA. MAIN CONCERN WILL BE THE STRONG WINDS EXPECTED TO DEVELOP BEHIND A COLD FRONT LATE TONIGHT. SUNDAY MORNING THE STRONG LOW PRESSURE SYSTEM ASSOCIATED WITH STRONG WINDS AND SHOWERS AND THUNDERSTORMS WILL HAVE MOVED EAST TOWARDS ONTARIO AND INTO THE GREAT LAKES REGION. NORTHWEST FLOW ALOFT AND COOL HIGH PRESSURE WILL PERSIST OVER NORTH DAKOTA SUNDAY. HIGH TEMPERATURES SHOULD RANGE FROM THE 60S OVER CENTRAL NORTH DAKOTA TO THE LOWER 70S IN THE SOUTHWEST.
347 AM EDT SAT AUG 22 2015 HIGH PRESSURE WILL BUILD INTO THE AREA THIS WEEKEND.
Area radars show a line of convection extending from the South Plains to the Diablo Plateau, courtesy of an upper trough moving thru Texas.
200 AM EDT SAT AUG 22 2015 HIGH PRESSURE WITH DRY AIR INTO THE WEEKEND.
THE NEXT CHANCE FOR PRECIPITATION WILL OCCUR LATE SUNDAY AND SUNDAY NIGHT WITH THE APPROACH AND PASSAGE OF A SURFACE COLD FRONT. EXPECT LOWS FROM THE LOWER 50S NE TO THE MID/UPPER 50S SW. HIGHS TO RANGE FROM NEAR 80 NORTH TO THE LOWER 80S SOUTH. MID LEVEL DIGGING TROF ACRS THE NRN PLAINS WILL ALLOW THE FLOW TO BACK OVER THE OHIO VALLEY. DIGGING MID LEVEL TROF OVER THE NRN PLAINS TO CLOSE OFF AND PUSH INTO THE GREAT LAKES SUNDAY/SUNDAY NIGHT.
Temperatures are generally a little cooler this morning than yesterday, except for the northern Sacramento Valley, where it is a few degrees warmer.

427 AM EDT SAT AUG 22 2015 COOLER AND DRIER WEATHER WILL LAST THOUGH THE WEEKEND.
THE MAIN ANTI-CYCLONIC CIRCULATION OVER BAJA CALIFORNIA TO SOUTHWEST CONUS AND A WEAKNESS/TROUGH AXIS FROM WEST ARKANSAS TO EAST TEXAS. ANOTHER TROUGH AXIS WAS NOTED IN THE NORTHERN STREAM OVER IDAHO AND WESTERN MONTANA. WAVE IN THE NORTHERN STREAM WILL PUSH EAST AND ALLOW THE RIDGE OVER SW CONUS TO AMPLIFY LATER TODAY INTO SUNDAY.
646 AM EDT SAT AUG 22 2015 COOLER AND DRIER WEATHER WILL LAST THOUGH THE WEEKEND.
A WEAK INVERTED 500MB TROUGH ACROSS NORTHEAST MEXICO MAY ALLOW ISOLATED SHOWERS TO DEVELOP ACROSS PORTIONS OF THE RIO GRANDE VALLEY SAT MORNING. HIGH RESOLUTION MODELS SUGGEST A MODERATE CHANCE OF MVFR A FEW HOURS EITHER SIDE OF SUNRISE ALONG THE HIGHWAY 69C/281 CORRIDOR. UPPER LEVEL TROUGH REMAINS OVER THE AREA PUMPING IN HIGH LEVELS OF MOISTURE INTO THE AREA. EARLY MORNING MID/HIGH CLOUDS STUNTED DIURNAL TEMPERATURE RISE IN THE MID/LOWER VALLEY SO ADJUSTED HOURLY TEMPERATURE GRIDS DOWN AND SHAVED A DEGREE OF THE HIGHS. UPPER TROUGH WEAKENS SATURDAY AND BEING REPLACED BY EXPANDING UPPER LEVEL RIDGING AND LOWER PWATS LEADING TO LOWER CHANCES FOR PRECIPITATION SATURDAY AND SATURDAY NIGHT. HIGH TEMPERATURES WILL BE WARMER AS WELL WITH HIGHS AROUND 100 IN THE FAR WEST TO MID 90S IN THE LOWER VALLEY.
212 AM EDT SAT AUG 22 2015 HIGH PRESSURE IN THE MID ATLANTIC STATES WILL BUILD INTO THE AREA TONIGHT THEN DISSIPATE SUNDAY.

246 PM CST MON FEB 8 2016 UPPER TROUGH DEEPENS OVER THE MID STATE TONIGHT, AS LOW CENTER MOVES SLOWLY EASTWARD FROM INDIANA TO OHIO. DEEP MOISTURE AND SCATTERED TO NUMEROUS SNOW SHOWERS CONTINUE TO ROTATE AROUND THE BACKSIDE AND UNDERSIDE OF THIS LOW CENTER, ACROSS MIDDLE TN, TONIGHT AND TUESDAY. TEMPERATURES ALSO CONTINUE TO TURN COLDER, WITH LOWS BY SUNRISE TUESDAY EXPECTED TO BE IN THE LOWER AND MIDDLE 20S.
COLD FRONT IS SOUTH OF OUR CWA AND GUSTY NORTHWEST WINDS HAVE DEVELOPED IN ITS WAKE. A COLD FRONT IS MOVING THROUGH THE REGION WHICH IS RESULTING IN A WIND SHIFT OUT OF THE NORTH AND BREEZY CONDITIONS. WATER VAPOR IMAGERY THIS MORNING SHOWING IMPRESSIVE MID LEVEL TROF AXIS DIVING RAPIDLY SE INTO THE AREA. PRECIP SHOULD COME TO AN END BY MIDNIGHT AS DRIER AIR FILTERS INTO THE LOWER LEVELS.
327 PM CST MON FEB 8 2016 LATEST WATER VAPOR LOOP AND RAP 500 MB ANALYSIS SHOW REGION IN STRONG NORTHWESTERLY FLOW WITH DEEP TROUGH EXTENDING ACROSS THE MIDWEST WHILE AN AMPLIFIED RIDGE EXTENDS ACROSS THE WEST COAST.
DUE TO A TIGHT PRESSURE GRADIENT IN WAKE OF A STRONG COLD FRONT. ANOTHER COLD FRONT WILL ENTER THE FOUR STATE REGION ON TUESDAY RETURNING STRONG BUT SLIGHTLY LOWER NORTHWEST WINDS OF 10-20 KNOTS WITH HIGHERGUSTS TO 17-25 KNOTS THROUGH 10/00Z.
/ISSUED 526 AM CST MON FEB 8 2016/ A FAST MOVING STRONG DRY COLD FRONT WILL MOVE THROUGH SE TX THIS MORNING AND EXIT SOUTH CENTRAL LOUISIANA AROUND THE NOON HOUR. THIS SHOULD ALLOW TEMPERATURES TO DROP BELOW THE FREEZING MARK OVER EAST TEXAS AND CENTRAL LOUISIANA.
322 PM CST MON FEB 8 2016 AN UPPER LEVEL RIDGE WILL PERSIST ACROSS THE WESTERN UNITED STATES WHILE AN UPPER TROUGH HANGS ON OVER THE EASTERN UNITED STATES. WITH LONGWAVE TROFS OVER THE E PAC AND ERN N AMERICA. WITH A RIDGE OVER WRN N AMERICA. ITS EASTWARD PROGRESSION WILL FORCE THE E PAC TROF ONSHORE SAT AND IT'S FCST TO ARRIVE HERE SUN.

SURFACE INVERSIONS IN THE LOWER VALLEYS AND SNAKE PLAIN WILL INCREASE IN STRENGTH THE NEXT FEW DAYS UNDER A STRONG RIDGE OF HIGH PRESSURE ALOFT. TEMPERATURES ON THE MOUNTAIN SLOPES WILL WARM INTO THE LOWER 40S.
229 PM EST MON FEB 8 2016 A COLD FRONT WILL MOVE THROUGH LATE THIS AFTERNOON AND EVENING.
HIGH AMPLIFIED UPPER RIDGE AXIS CENTERED ALONG THE WEST COAST NORTH INTO CANADA IS FORECAST TO SLOWLY MOVE VERY SLOWLY EAST TOWARD LAS VEGAS NORTH THROUGH THE PERIOD.
GUSTY NORTH WINDS CONTINUE BEHIND A COLD FRONT THAT PASSED THIS MORNING. WINDS WILL GRADUALLY RELAX THIS EVENING AS HIGH PRESSURE SETTLES FURTHER OVER THE REGION.
NOT MUCH HAPPENING WEATHER-WISE AS HIGH PRESSURE RIDGING WILL KEEP DRY CONDITIONS OVER OUR AREA FOR NEXT SEVERAL DAYS. CURRENT FORECAST IN GOOD SHAPE; JUST MADE A FEW MINOR ADJUSTMENTS TO SKY COVER TO BETTER MATCH LATEST SATELLITE IMAGERY WHICH SHOWS BROAD AREA OF HIGH CLOUD SPILLING OVER THE EAST SIDE OF THE RIDGE PATTERN INTO MONTANA.
CURRY COUNTY COASTAL TEMPERATURES ARE IN THE LOWER 70S. DOESN'T LOOK LIKE THE LOW CLOUDS ARE TOO THICK SO WE EXPECT MOSTLY SUNNY SKIES PREVAILING BY EARLY AFTERNOON AREA- WIDE. A THERMAL TROUGH ALONG THE COAST WILL MOVE NORTH AND PUSH INLAND BY THIS EVENING. WINDS WILL REMAIN LIGHT BUT BECOME SOUTHERLY THIS EVENING AS LOW PRESSURE DEEPENS BEYOND 130W.
EVEN THOUGH SURFACE TEMPERATURES REMAIN IN THE LOW 40'S MOST AREAS, THE FREEZING LEVEL IS NOT VERY HIGH, AND LARGE DEW POINT SPREADS AT THE SURFACE DO LEAVE SOME ROOM FOR EVAPORATIVE COOLING.
331 PM CST MON FEB 8 2016 CURRENT SURFACE ANALYSIS PLACES LOW OVER THE GREAT LAKES WITH RIDGE RUNNING THROUGH THE WESTERN PLAINS. UPPER LEVEL ANALYSIS PLACES RIDGE OVER THE WESTERN CONUS WITH LOW NEAR LAKE MICHIGAN WHILE FAST NORTH-NORTHWESTERLY FLOW REMAINS OVER OUR AREA. BUT CHANCES SWITCH TOWARDS RAIN OVER PORTIONS OF THE WEST AS WARMER AIR TRIES TO WORK EASTERLY.
A 125 KT JET ANCHORED BETWEEN AN UPPER RIDGE OVER THE WESTERN STATES AND AN UPPER LOW OVER THE GREAT LAKES WILL PUSH EAST INTO THE GREAT PLAINS TODAY. WARM ADVECTION WITH SLIGHT DOWNSLOPING IS EXPECTED TODAY TO BRING WARMER TEMPERATURES TODAY ACROSS THE AREA WITH THE WARMEST AREAS FOUND OVER THE FOOTHILLS AND METRO AREAS. IT COULD STAY COOLER. GUSTS TO 60 MPH WILL BE POSSIBLE IN THE HIGHER TERRAIN AND INTO SOUTH PARK. THOUGH IT WILL BE A WARMER NIGHT UNDER THE WARM ADVECTION AND BREEZY NORTHWEST WIND PATTERN. A HIGH AMPLITUDE RIDGE CENTERED OVER THE WESTERN U. WILL BRING DRY AND WARMER WEATHER TO THE FORECAST AREA FOR THE REST OF THE WEEK.
DRY AND MUCH WARMER THIS WEEK WITH AFTERNOON HIGHS WELL ABOVE AVERAGE FOR FEBRUARY. STRONG HIGH PRESSURE WILL DOMINATE OUR WEATHER INTO THE COMING WEEKEND. DRY AND MORE DRY WITH ONLY SOME PATCHES OF CIRRUS ON THE NORTHERN FRINGE OF A WEAK DISTURBANCE DIRTYING UP THE BASE OF THE RIDGE TO OUR SOUTH. HIGH PRESSURE WILL BRING DRY CONDITIONS WITH WELL ABOVE AVERAGE HIGH TEMPERATURES THIS WEEK.
FORECAST SOUNDINGS FOR THE BOISE AREA DIFFERENT THAN YESTERDAY IN THAT THE LOWER AIRMASS IS NOT SATURATED LIKE IT WAS INDICATING YESTERDAY. RIDGE CONTINUE TO AMPLIFY AND WARMER AIR STILL EXPECTED TO MOVE IN AROUND 700MB KEEP INVERSION IN PLACE.
MAX TEMPS ON TUESDAY WILL BE SIMILAR TO TODAY WITH A RIDGE OF HIGH PRESSURE EXTENDING FROM CANADA INTO NORTHERN MEXICO. THE HIGH SHIFTS EAST TUESDAY NIGHT AND LOW PRESSURE SHOULD BEGIN TO DEVELOP OVER THE WESTERN HIGH PLAINS. THIS WILL ALLOW FOR ONSHORE WINDS AND A RETURN TO WARMER TEMPERATURES WED-FRI. UPPER LEVEL RIDGING OVER THE DESERT SW WILL FLATTEN A BIT AS A S/WV OVER THE CENTRAL ROCKIES MOVES EAST ON FRI NIGHT.
146 PM PST MON FEB 8 2016 HIGH PRESSURE AND GUSTY OFFSHORE WINDS WILL BRING WELL ABOVE NORMAL TEMPERATURES THIS WEEK WITH POSSIBLE RECORD TEMPERATURES TODAY AND TUESDAY. THE HIGH WILL WEAKEN AT THE END OF THE WEEK FOR A COOLING TREND.
with temps running some 6-9 degrees warmer than yesterday over the N Valley. Omega Block/Strong high pressure along the W Coast will shift inland as the deep cyclone over the Great Lakes/Ohio Valley swings up to the NE. Energy from the Gulf of AK trof will weaken as it encounters the blocking ridge so a dry and unseasonably warm week of wx is ahead for Norcal.
TEMPERATURES HAVE RISEN ABOVE FREEZING FOR MOST LOCATIONS AT THIS POINT. SO HAVE GONE AHEAD AND CANCELLED THE WINTER WEATHER ADVISORY FOR FREEZING RAIN IN THE EAST. LIGHT RAIN IS MOVING IN FROM THE WEST OUT AHEAD OF A COLD FRONT. UNTIL A VIGOROUS SHORT WAVE TROUGH ROTATES THROUGH THIS AFTERNOON. THE ONLY EXCEPTION TO THIS WILL BE THE HIGHER ELEVATIONS ALONG THE SOUTHEAST AS THE COLUMN COOLS QUICKER ALOFT. AS AN UPPER LEVEL TROUGH GRADUALLY DEEPENS ACROSS THE OHIO VALLEY AND SEVERAL EMBEDDED WAVES ROTATE THROUGH EASTERN KENTUCKY. WITH 4 TO 6 INCHES FOR THE HIGHEST TERRAIN IN THE SOUTHEAST. WITH READINGS FALLING BELOW FREEZING BY THIS EVENING. BROAD MEAN TROUGH WILL REMAIN ANCHORED OVER THE EASTERN HALF OF THE CONUS THROUGH THE PERIOD AS SEVERAL IMPULSES ROTATE THROUGH THE BASE.
SNYDER HIGH PRESSURE WILL BRING GENERALLY LIGHT WINDS AND UNSEASONABLY MILD DAYTIME TEMPERATURES THIS WEEK. STRONG VALLEY INVERSIONS WILL CONTINUE TODAY, THEN WEAKEN DURING THE NEXT FEW DAYS AS WEAK LOW PRESSURE SLOWLY APPROACHES THE WEST COAST. /ISSUED 309 AM PST MON FEB 8 2016/ THE MAIN SHORT TERM WEATHER ISSUE IS THE GUSTY EAST RIDGE LEVEL WINDS ALONG THE SIERRA CREST AND CARSON RANGE, GENERALLY RANGING FROM 50-60 MPH SINCE YESTERDAY WITH A MAXIMUM GUST OF 74 MPH AT ALPINE MEADOWS SUMMIT. OTHERWISE, AS THE RIDGE AXIS MOVES EAST OF THE SIERRA CREST BY THIS EVENING, OVERALL WIND SPEEDS WILL DECREASE WITH RIDGE LEVEL GUSTS BELOW 30 MPH.
WEATHER ACROSS THE AREA WILL REMAIN DRY AND UNSEASONABLY WARM THIS WEEK AS STRONG HIGH PRESSURE HOLDS FIRM OVER THE WESTERN U. MORNING SOUNDING DOES INDICATE SOME SUBTLE LOW LEVEL COOLING SO WE MAY TOP OUT A DEGREE OR TWO COOLER THAN YESTERDAY.
1248 PM EST MON FEB 8 2016 COLD FRONT ARRIVES TONIGHT WITH LITTLE FANFARE.
357 PM CST MON FEB 8 2016 THE UPPER-AIR PATTERN FOR MOST OF THIS FORECAST PACKAGE WILL FEATURE A STRONG RIDGE ANCHORED OVER THE INTER-MOUNTAIN WEST AND A DEEP TROUGH OVER THE EASTERN CONUS. WITH AN AREA OF LOW PRESSURE PARKED OVER THE BAJA PENINSULA. THE RIDGE WILL WEAKEN SOME BY THE MIDDLE OF THIS WEEK. AS THE RIDGE WEAKENS AND SHIFTS EAST HEADING INTO THE WEEKEND. A WEAK COLD FRONT MAY EDGE INTO THE PANHANDLES AND KNOCK TEMPERATURES A LITTLE CLOSER TO NORMAL.
1039 AM MST MON FEB 8 2016 18Z TAF CYCLE STRONG RIDGE OF HIGH PRESSURE OVER WRN STATES WILL KEEP A DRY NLY FLOW ALOFT ACROSS NM WITH VFR CONDITIONS AND LIGHT SFC WINDS EXPECTED AT ALL TAF SITES DURING THE NEXT 24 HOURS. WARM AND DRY CONDITIONS WILL BE THE RULE THIS WEEK AS AN UPPER LEVEL RIDGE OVER THE WEST COAST INCHES EASTWARD.
A COLD FRONT CONTINUES TO PASS THROUGH DEEP SOUTH TEXAS AND THE RIO GRANDE VALLEY AT THIS TIME. MODERATE WINDS BEHIND THE COLD FRONT WILL BECOME LIGHT AROUND SUNSET. COLD FRONT WILL BE MOVING INTO THE REGION JUST BEFORE NOON. THE COLD FRONT IS DROPPING SOUTHWARD THROUGH SOUTH TEXAS. TEMPS BEHIND THE FRONT WILL BE A TOUCH COOLER TODAY. WITH TEMPS DROPPING INTO THE LOWER 40S.
1000 AM PST MON FEB 8 2016 HIGH PRESSURE AND GUSTY OFFSHORE WINDS WILL BRING WELL ABOVE NORMAL TEMPERATURES THIS WEEK WITH POSSIBLE RECORD TEMPERATURES TODAY AND TUESDAY. THE HIGH WILL WEAKEN AT THE END OF THE WEEK FOR A COOLING TREND.
SLOW COOLING AND SLIGHTLY HIGHER RELATIVE HUMIDITY BY THE WEEKEND AS HIGH PRESSURE ALOFT WEAKENS. WATER VAPOR SATELLITE IMAGERY DISPLAYED A LARGE UPPER-LEVEL RIDGE ALONG THE WEST COAST.
AFTER A FEW HOURS OF DRY CONDITIONS WITH A CEILING ON THE LOWER END OF THE VFR RANGE.
