THERE IS AN UPPER LEVEL LOW THAT SHOULD MOVE THROUGH THE FORECAST AREA AS WELL. WITH CLOUDS AND PRECIPITATION AROUND THE AREA EXPECT TEMPERATURES TO BE A LITTLE COOLER. ONE OF THE MAIN QUESTIONS FOR THE DAY IS AS THE LOW DRIFTS TO THE NORTHEAST.
SFC WINDS WILL REMAIN OUT OF THE NORTHWEST THROUGH 0100Z AS OUR TERMINALS WILL REMAIN ON THE BACK SIDE OF A COLD FRONT, THEN GO LIGHT & VARIABLE FOR TONIGHT. SOME STRATUS REMAINS IN PLACE ACROSS EASTERN AND SOUTHEASTERN OK, BUT EXPECT THIS TO CONTINUE TO SHIFT EAST AS WINDS VEER WITH APPROACHING COLD FRONT NOW NEARING THE I44 CORRIDOR. COLD FRONT WILL MOVE THROUGH THE AREA WITH COOLER TEMPERATURES TODAY.
The next upper low will begin to eject out of the desert southwest later Thursday. with a warm front (along with improving low-level moisture) lifting into southern OK late Thursday into Thursday night.
A WEAK COLD FRONT WILL MOVE INTO THE FCST AREA THIS MORNING WITH WINDS VEERING TO NW. /ISSUED 420 AM CDT WED APR 27 2016/ UPPER LEVEL TROUGH OVER COLORADO AND WYOMING WILL SHIFT SLOWLY EWD ACROSS THE CENTRAL PLAINS TODAY. SHORT WAVE RIDGING IN ITS WAKE WILL MOVE TO 4-CORNERS BY MIDDAY AND ERN NEW MEXICO BY EVENING. A COLD FRONT WILL MOVE INTO THE FCST AREA THIS MORNING WITH WINDS VEERING TO NW AND NORTH.
THOUGH TEMPERATURES SHOULD BE A COUPLE OF DEGREES COOLER THAN TODAY ACROSS THE COASTAL PLAINS AS SE SFC WINDS INCREASE THROUGH THE DAY /GREATER MARINE INFLUENCE THAN TODAY/. IN COMBINATION OF AN APPROACHING H5 S/W TROUGH.
SKIES WILL CLEAR FROM WEST TO EAST THROUGH LATE MORNING AS THE UPPER LEVEL LOW CURRENTLY OVER WESTERN KANSAS MOVES EASTWARD. AHEAD OF THIS LOW.
A WEAK UPPER TROUGH WILL MOVE ACROSS WESTERN WASHINGTON TODAY PRODUCING MAINLY CLOUDY SKIES AND A CHANCE OF LIGHT SHOWERS FOR THE COAST. AN UPPER RIDGE WILL BRING MOSTLY SUNNY WEATHER THURSDAY.

1253 PM EDT WED APR 27 2016 HIGH PRESSURE CENTERED NORTH OF MICHIGAN WILL KEEP DRY NORTHEAST FLOW ENTRENCHED OVER THE REGION FOR THE REMAINDER OF TODAY. APPROACHING LOW PRESSURE WILL CAUSE CLOUDS TO THICKEN AND LOWER STARTING EARLY THURSDAY MORNING. AN ELEVATED FRONTAL BOUNDARY WILL LIFT INTO SOUTHEAST MICHIGAN THURSDAY AS THE LOW TRACKS ACROSS THE OHIO VALLEY. BUT DRY AIR REMAINING IN THE LOW LEVELS MAY KEEP CEILINGS JUST ABOVE 3000 FEET. THIS WILL KEEP CONDITIONS DRY THROUGH THE DAY AS THE LOW OUT TO THE WEST ENCROACHES ON THE AREA LATER TONIGHT.
621 AM CDT WED APR 27 2016 THE MID/UPPER TROUGH RESPONSIBLE FOR THE RECENT ACTIVE WEATHER IS PROGGED TO MOVE SLOWLY EAST/NORTHEAST ACROSS THE CENTRAL PLAINS STATES TODAY.

541 AM MDT WED APR 27 2016 HAVE ISSUED AN UPDATE TO ALL PORTIONS OF THE FORECAST TO REDUCE POPS ACROSS THE AREA NOW THAT THE UPPER LOW HAS SHIFTED FAR ENOUGH EAST AWAY FROM THE CWA TO ALLOW FOR LITTLE AREAL COVERAGE OF SHOWERS REMAINING. THE AREA OF LOW PRESSURE THAT BROUGHT SHOWERS AND STORMS TO THE REGION OVER THE LAST COUPLE OF DAYS WILL SLOWLY EXIT OFF TO THE NORTHEAST THROUGH THE DAY TODAY. ANOTHER AREA OF LOW PRESSURE WILL APPROACH THE REGION LATE THURSDAY AFTERNOON AND INTO THE EVENING HOURS.
637 AM CDT WED APR 27 2016 12Z TAF CYCLE A BRIEF UPPER RIDGE WILL BUILD IN OVER THE PANHANDLES TODAY AND TONIGHT. WITH THE NAM BEING NOTABLY FASTER WITH THE UPPER LOW AND DRIER FOR OUR REGION. A REINFORCING ROUND OF COOLER AIR WILL FILTER INTO THE PANHANDLES. THOUGH BREEZY NORTHWEST WINDS MAY HELP IT FEEL A LITTLE COOLER. AS THE ACTIVE UPPER AIR PATTERN BRINGS THE NEXT CLOSE UPPER-LEVEL LOW PRESSURE SYSTEM INTO THE FOUR CORNERS REGION. THIS WILL TURN FLOW ALOFT OUT OF THE SOUTHWEST AND DEVELOP AN AREA OF LOW PRESSURE AT THE SURFACE OVER EASTERN NM AND WEST TX BY TOMORROW EVENING.
ISSUED BY NATIONAL WEATHER SERVICE CARIBOU ME 1221 PM EDT WED APR 27 2016 AN UPPER TROUGH WILL PROVIDE A FEW CLOUDS OVER NORTHERN NEW HAMPSHIRE AND THE WESTERN MAINE MOUNTAINS LATE TODAY. OTHERWISE A RIDGE OF COOL. CANADIAN HIGH PRESSURE WILL SETTLE IN THROUGH EARLY THIS WEEKEND.
1100 AM MDT WED APR 27 2016 HAVE ISSUED AN UPDATE TO ALL PORTIONS OF THE FORECAST TO REDUCE POPS ACROSS THE AREA NOW THAT THE UPPER LOW HAS SHIFTED FAR ENOUGH EAST AWAY FROM THE CWA TO ALLOW FOR LITTLE AREAL COVERAGE OF SHOWERS REMAINING. THE AREA OF LOW PRESSURE THAT BROUGHT SHOWERS AND STORMS TO THE REGION OVER THE LAST COUPLE OF DAYS WILL SLOWLY EXIT OFF TO THE NORTHEAST THROUGH THE DAY TODAY. ANOTHER AREA OF LOW PRESSURE WILL APPROACH THE REGION LATE THURSDAY AFTERNOON AND INTO THE EVENING HOURS.
TROUGH MOVING IN FROM THE WEST WILL BE THE DOMINANT FEATURE FOR THE NEXT THREE DAYS. THEN AN UPPER LOW FROM THE NORTHWEST. STRONGER THAN THE TROUGH. THIS SHOULD INCREASE THE SHOWER AND THUNDERSTORM THREAT FOR THE HIGHEST PROBABILITY OF THIS NEAR TERM PERIOD. BUT IT IS VERY LIGHT UNTIL THE LOW APPROACHES FRI.
1128 AM CDT WED APR 27 2016 Upper level low pressure was centered near the KS/NE border late this morning. At the surface, low pressure was located near Lincoln, NE with a Pacific cold front extending south of the low across E OK. The next upper low will begin to eject out of the desert southwest later Thursday. with a warm front (along with improving low-level moisture) lifting into southern OK late Thursday into Thursday night.
750 AM EDT WED APR 27 2016 HIGH PRESSURE OVER THE LAKES WILL WEAKEN INTO TONIGHT. LOW PRESSURE WILL MOVE UP THE OHIO VALLEY THURSDAY AND THURSDAY NIGHT.
A COLD FRONT MOVING THROUGH WILL BRING SCATTERED SHOWERS AND A FEW THUNDERSTORMS TO OUR REGION TODAY AND THIS EVENING. A COLD FRONT IS FORECAST TO MOVE THROUGH OUR REGION LATER TODAY AND BRING SCATTERED SHOWERS PLUS A FEW THUNDERSTORMS TO OUR REGION. MODELS HAVE CONTINUED TO FOCUS THE MAJORITY OF MOISTURE FOR TODAY OFF TO OUR EAST HOWEVER WITH THE LOW FORECAST TO PASS NEAR THE NORTH BAY OR SF BAY THIS AFTERNOON PLUS FAVORABLE CONVECTIVE PARAMETERS WE SHOULD SEE SHOWERS FIRING UP. A RIDGE OF HIGH PRESSURE WILL BUILD TO THE COAST LATER IN THE WEEK WITH DRY CONDITIONS ALONG WITH WARMER TEMPERATURES FORECAST.
657 AM CDT WED APR 27 2016 NEGATIVELY TILTED AND ELONGATE UPPER TROUGH AXIS CURRENTLY EXTENDS FROM SOUTHEASTERN MONTANA INTO NORTHEAST COLORADO TO THE BASE IN THE OKLAHOMA PANHANDLE/SOUTHWESTERN KANSAS. THE COLD CLOSED UPPER LOW WILL TIGHTEN UP AND SHIFT NORTHEAST. COOLER AIR. WRAP INTO THIS LOW TONIGHT WITH DEFORMATION BAND SETTING UP ACROSS NORTHEAST NEBRASKA. UPPER LOW EXITS EAST OF THE CWA THURSDAY AFTERNOON ENDING ANY REMAINING PCPN CHANCES OVER OUR NORTHERN COUNTIES.
STIFF NORTHEAST WINDS WILL CONTINUE TO ADVECT DRY AIR INTO THE LOW LEVELS WHICH COMBINED WITH THE VERY SLOW MOVEMENT OF THE APPROACHING UPPER LOW WILL LIKELY KEEP MOST OF THE AREA DRY THROUGH EARLY TO MID AFTERNOON. UPPER LOW SHOULD MOVE ACROSS THE CWA THURSDAY AND SHOULD BE ENOUGH TO SUPPORT ISOLD TO SCTD SHOWERS EVEN THOUGH IT WILL BE WEAKENING QUICKLY.
941 AM EDT WED APR 27 2016 HIGH PRESSURE BUILDING ACROSS THE EASTERN GREAT LAKES SHOULD BRING DRY WEATHER TO MOST LOCATIONS TODAY.
522 AM MDT WED APR 27 2016 THE AREA OF LOW PRESSURE THAT BROUGHT SHOWERS AND STORMS TO THE REGION OVER THE LAST COUPLE OF DAYS WILL SLOWLY EXIT OFF TO THE NORTHEAST THROUGH THE DAY TODAY. ANOTHER AREA OF LOW PRESSURE WILL APPROACH THE REGION LATE THURSDAY AFTERNOON AND INTO THE EVENING HOURS.
AN UPPER LEVEL LOW PRESSURE OFF THE SOUTHWEST COAST OF OREGON IS DROPPING INTO NORTHERN CALIFORNIA TODAY. ANOTHER AREA OF PRECIPITATION THIS MORNING IS OVER SOUTHWEST OREGON DIRECTLY UNDER THE LOW PRESSURE CENTER.
THE NAM/GFS ARE NOT AS FAR EAST AND NORTH WITH THE HIGHER QPF AMOUNTS. THE POP CHANGES ALSO RESULTED IN WARMER TEMPERATURES NORTH AND EAST WITH MID 50S NORTH CENTRAL. WHEN THE HIGHEST QPF AMOUNTS ARE EXPECTED. GIVEN THE HIGHER ELEVATIONS AND FORECAST HIGHS IN THE MID 30S.

SOME STRATUS REMAINS IN PLACE ACROSS EASTERN AND SOUTHEASTERN OK, BUT EXPECT THIS TO CONTINUE TO SHIFT EAST AS WINDS VEER WITH APPROACHING COLD FRONT NOW NEARING THE I44 CORRIDOR. COLD FRONT WILL MOVE THROUGH THE AREA WITH COOLER TEMPERATURES TODAY.
SPC HAS LOWERED AR TO ONLY A MARGINAL THREAT THIS AFTERNOON TO EVENING WITH THE COLD FRONT. ISOLATED/SCATTERED STORMS COULD POP UP IN THE EASTERN HALF OF THE STATE AS A COLD FRONT CROSSES THE REGION.
HIGH PRESSURE OVER THE WESTERN ATLANTIC WILL BUILD IN SOME ACROSS THE FLORIDA PENINSULA THE NEXT FEW DAYS. EXCEPT COOLER NEAR THE WATER.
ANOTHER UPPER TROUGH HAS ENTERED THE WEST COAST. WITH A CLOSED LOW EMBEDDED IN THE TROUGH DIGGING INTO NORTHERN CALIFORNIA. SUPPORTED BY THE APPROACHING TROUGH. LATEST GFS/MAV HAS TRENDED WETTER AND COOLER WITH INCOMING TROUGH FOR TODAY. YESTERDAY/S GFS DUG THE TROUGH FARTHER SOUTH INTO SRN CALIF AND ARIZONA FOR TODAY. MAV/S HIGHEST POPS AND LARGEST QPF ARE IN OUR NRN-MOST MOUNTAINS WHERE AN INCOMING SURFACE COLD FRONT IS STRONGER. MAV MAX TEMPS HAVE ALSO TRENDED A LITTLE COOLER. AND ALSO COOLER THAN LATEST MET. LOCAL TEMPERATURE SCHEME FAVORS THE COOLER MAV.
WITH AMPLE SUNSHINE AND DEWPOINTS IN THE LOWER 60S. SHOWER ACTIVITY PRECEDING AN APPROACHING COLD FRONT COULD BEGIN AFFECTING THE TERMINALS LATER THIS AFTERNOON AND EVENING.
ISOLATED TO SCATTERED AFTERNOON SHOWERS INTERIOR/WEST COAST REST OF THIS WEEK BEFORE DRY CONDITIONS THIS WEEKEND OVER ALL HIGH PRESSURE WILL REMAIN NEARLY STATIONARY OVER THE WESTERN ATLANTIC WATERS TODAY INTO THURSDAY. AS LOW PRESSURE OVER THE CENTRAL UNITED STATES WEAKENS WHILE MOVING INTO THE TENNESSEE VALLEY.
COLD FRONT WILL MOVE THROUGH THE AREA WITH COOLER TEMPERATURES TODAY.
AND GET TO 25-30 OVERNIGHT BUT THEN LEVEL OFF AND START VEERING AS THE UPPER TROUGH RIDES ACROSS TO OUR NORTH. STORMS ARE STILL POSSIBLE TONIGHT AS MORE AND MORE MOISTURE PUSH INTO THE AREA AHEAD OF THE WEAK COLD FRONT.

A WARM FRONT HAS DEVELOPED NORTH OF MIDDLE TENNESSEE, WITH A WARM, MOIST SOUTHERLY FLOW INCREASING THIS MORNING. A COLD FRONT APPROACHING FROM THE WEST WILL PROVIDE SUFFICIENT LIFT FOR WIDESPREAD THUNDERSTORM DEVELOPMENT, WITH THE MOST ACTIVE PERIOD BEING THE AFTERNOON THROUGH EARLY EVENING.
624 AM CDT WED APR 27 2016 /12Z TAFS/ Drier air in the wake of a Pacific cold front will continue to advect into the CWA this morning with winds becoming westerly at 8-12 kts. /issued 419 AM CDT WED APR 27 2016/ (Today and tonight) The Pacific cold front has moved through West Central TX and much drier air is being advected into the CWA by west winds around 10 mph. Max temperatures were kept closer to the cooler NAM MOS, with highs in the mid 80s across most of the CWA. Despite south winds of 5-10 mph tonight, relatively dry air and mostly clear skies will allow temperatures to fall into the low/mid 50s.
THE WESTERN ATLANTIC SUBTROPICAL RIDGE EXTENDS WEST ACROSS THE FLORIDA PENINSULA TO THE GULF OF MEXICO. TEMPERATURES ARE IN THE LOWER 80S WITH DEWPOINTS APPROACHING 70.
922 AM PST Sun Nov 13 2016 Warmer through Monday under strengthening high pressure.
Then tonight a narrow ridge will be followed zonal flow on Monday.
1032 AM MST Sun Nov 13 2016 The upper trough currently moving east of the Rockies and across the northern high plains today kicks the low out of the southern plains. The trough and low continue east over the eastern plains tonight and the Mississippi Valley region on Monday. This allows a ridge to redevelop over the western U.
A high pressure system is going to control Indiana weather into Monday.
For Monday, isolated patches of light rain are forecast for the central and eastern portions of the BRO CWFA, where available moisture will be best, as a weak 500 mb trough swings through from west to east. Drier weather will set in Monday night as a more pronounced mid- level trough approaches from the west, and a more robust influx of drier air occurs at the surface.
VFR to MVFR conditions are expected to prevail through the valid period with the lower ceilings becoming more common later tonight into Monday morning.
Otherwise, the weak inverted coastal trough in the north will weaken and a high pressure ridge over the Atlantic will provide a light east/southeast wind flow.
Southwest winds still look to be gusting around 25 knots this afternoon, quickly subsiding early this evening, but sustained winds should hold in the 5-10 knot range overnight as cold front approaches.
1254 PM EST Sun Nov 13 2016 High pressure and a dry airmass will remain in place across the region through the first part of the week as temperatures remain slightly above normal. After earlier addition of river valley steam fog, the only subsequent very slight changes made to the forecast were to slightly increase the sw surface wind flow as the center of the high slowly sinks south and especially the western forecast area with warm air advection beginning in earnest.
233 PM EST Sun Nov 13 2016 A ridge of high pressure will remain across the area through Monday night with dry air and seasonably mild temperatures.
325 PM CST Sun Nov 13 2016 For the 13/18Z terminals, high pressure across the region to maintain VFR conditions through the terminal forecast period. /issued 1126 AM CST Sun Nov 13 2016/ The region remains in a weak omega block pattern this morning as a closed upper low begins to fill over central Oklahoma and troughing lifts northeastward. The ridge axis just downstream over much of our region will continue to be the main influence on our weather today as southwest flow aloft continues to supply mid and high clouds over much of the area. High pressure at the surface will continue to drift southeast, and light winds will veer slightly to the east and southeast with time.
1023 AM EST Sun Nov 13 2016 Canadian high pressure will move just to our south today.
242 PM CST Sun Nov 13 2016 High pressure has shifted south of the cwa while a weak cold front (more of a wind shift line) extended from western MN to northern Nebraska. Tonight: High level cirrus clouds will gradually increase and along with southwest winds, temperatures will be warmer than the past couple of nights. Monday: An upper level trough and weak cold front moves across the cwa during the day. However, forcing is weak and this system is moisture-starved due to high pressure across the southern states. Maximum temperatures should range from the mid 50s to the lower 60s.
A warm front will drag across the northern portion of the forecast area today producing a low chance of light precipitation. This will be followed by a cold front slowly sagging southward overnight and on Monday bringing a higher chance of precipitation to the entire forecast area. Temperatures will be cooler today due to cloud cover and less wind mixing while the overnight temperatures will stay warm due to the cloud cover.
1047 AM EST Sun Nov 13 2016 High pressure will continue across region today resulting in sunny skies and mild temperatures. High pressure will continue to settle slowly east out of the Ohio Valley providing clear skies today. Using blended MOS pops yields a small chance so confidence is high that most of the region will remain controlled by the sprawling high pressure and remain dry.
The first short wave trough will come across tonight through Monday. Only some very weak pv advection in the 500-300 mb layer is expected Monday with the passage of the short wave trough. The frontogenesis along the weak cold front, looks to be very weak and disorganized and only about 1 ubar/s of up glide should occur on the 290K isentropic surface tonight ahead of the front.
1101 AM EST Sun Nov 13 2016 High pressure will bring fair weather to the region to start off the new week, with temperatures warming into the 50s. High pressure nosing into the northeastern U.
349 PM EST Sun Nov 13 2016 High pressure will result in another night with clear skies and cool temperatures by morning.
439 PM EST Sun Nov 13 2016 A ridge of high pressure will remain across the area through Monday night with dry air and seasonably mild temperatures.
330 PM EST Sun Nov 13 2016 High pressure remains in control across eastern KY this afternoon. We also get brushed by the upper low and enough moisture in place will being some clouds to the far east by the afternoon. This as a dry cold front approaches form the west.
Just how widespread the low clouds will be is always difficult on the first night, but have increased cloud cover to mostly cloudy for late tonight and early Monday morning. For Monday, low level winds will swing a little more southwest and west during the morning, in response to a weak cold front approaching. This will both drive the low clouds away and boost afternoon temperatures. The front is weak, more of a wind shift than anything else, with afternoon highs still in the low to mid 70s across the area.
Meanwhile, an associated cold front observed over the western Dakotas as of 08z will advance southeast through the mid Missouri Valley this afternoon and tonight. The cold front will not reach our forecast area until mid afternoon, allowing high temperatures to warm into the mid to upper 60s ahead of it. Weak low-level cold advection in the wake of the frontal passage Monday morning will transition to downslope warming by afternoon with highs generally in the lower 60s.
311 PM EST Sun Nov 13 2016 High pressure dominating the US will provide the North Country with dry and quiet weather through most of this week.
143 PM PST Sun Nov 13 2016 Warmer through Monday under strengthening high pressure.
1131 AM CST Sun Nov 13 2016 High pressure extending west from the lower Ohio Valley continues to influence our region this morning. with nothing but clear skies seen over the Lower Missouri Valley. expect warmer temps than yesterday. Nice and warm day on tap for tomorrow despite the passage of a weak cold front during the late morning and afternoon hours. Highs tomorrow should be a few degrees warmer than today.
The gradient will tighten between the front over northern Florida and high pressure to the north causing an increase in the winds to around 15 knots, and some stronger gusts over the northern waters. Winds will be on the decrease by Monday as another area of high pressure settles into the area.
H50 Omega high centered over the mid MS River Valley will slowly shift east and weaken during the next 24 to 48 hours, eventually allowing a mid lvl trof to ease eastward into the region on Monday. The trof will be moisture-starved at first with little surface reflection. However, a secondary short wave will drop southeast into the west side of the main trof later Monday/Monday evening, along with an associated surface front.
Closer to home, low level flow was relatively weak and primarily influenced by the ridge to the north. Otherwise, skies have generally cleared this morning as the influence from the upper low are shifting east. The sheared trough/circulation shifts east tonight clearing the sky.
High High pressure south of the state will continue to nudge southward as a trough approaches tonight and moves through on Monday. Low level moisture is progged to increase form the south later tonight into Monday ahead of the trough. Given the extent of dry air current in the low levels though, trended the forecast toward less clouds and higher cloud bases. Looks like a dry trough passage tomorrow.
1022 AM EST Sun Nov 13 2016 High pressure will maintain dry weather into the mid week. No changes were needed for the late morning update as insolation and weak warm advection on the extended flank of a Southeast Canadian trough will support moderating temperature today. Forecast lows are about 5 degrees below average, but a few degrees warmer than this mornings lows at most locations. Model world has not been consistent with this feature, but effects on the immediate area should be limited to an increase in cloud cover, more so over the ridge zones.
Otherwise weak cold front is on schedule to begin its push through our CWA later tonight and then stall across the southern Rolling Plains by early Monday morning. Mondays highs should be similar to today despite shift to northerly surface winds behind the weak cold front due to height rises associated with upper level ridging working it way toward West Texas from our west. Relatively small changes were needed once again through mid week as a stout progressive upper level high pressure ridge passes through the area. Temperatures will climb 10 to 15 degrees warmer than normal.
334 PM CST Sun Nov 13 2016 With the upper level low moving off to the east, temps have risen 10 degrees higher than yesterday. Winds have started turning northerly in the northwestern Panhandles as a weak cold front moves through. Winds will continue turning northerly for the remaining counties overnight but temps will remain above freezing. Ridging will begin building in tomorrow and lead to dry and warm conditions for the beginning of the work week. By midweek, a negatively tilted longwave trough approaches the Rockies. This will all depend on timing and if the stronger winds line up with the lower dewpoints.
Tonight into Monday, a cold front draped from northeast to southwest across the northern Gulf will push slowly towards south Florida.
254 PM EST Sun Nov 13 2016 Scattered cumulus was noted over the Florida Straits and Hawk Channel, otherwise skies were sunny with temperatures in the lower 80s, and dewpoints 63-68F. A flat upper ridge continues over the northwest Caribbean with a mid level low pressure over Georgia lifting slowly northeast. Over the next 24-36 hours, the lifting east coast trough and attendant developing surface wave will keep the Florida pressure gradient relatively weak but intact, resulting in continued light to gentle northeast to east winds.
Post frontal west winds bringing good mixing causing unusually mild temperatures across the northwest with Williston, Minot and vicinity in the low to mid 50s this morning. The short term begins with a flattened h500 ridge over the central CONUS with progressive flow moving onshore across the Pacific northwest. A modified Pacific cold front will move through the state today as a dry frontal passage. This afternoon and tonight an area of strato-cu will move south with the cooler air behind the front and linger across the north and east. There should be enough wind to mix the air and cloud cover to hold temperatures up in the mid 30s most areas but lowed mins to lower 30s south and southwest where past few nights it has gotten cooler than expected.
157 PM EST Sun Nov 13 2016 High pressure weakens today.
