233 PM CST Wed Nov 18 2020 The region will remain under ridging aloft through the short term. /28/ Tomorrow night through Wednesday: The forecast period starts off tomorrow night with surface ridging across the Southeast States beneath weak quasi-zonal flow aloft. Temperatures will gradually moderate with afternoon highs in the low to mid 70s.
255 PM CST Wed Nov 18 2020 (Issued 255 PM CST Wed Nov 18 2020) Tonight through Thursday night: Gusty winds will continue overnight and into tomorrow as a low pressure system moves to our north and east. Otherwise, expect a mix of sun and clouds tomorrow with highs in the low 60s, owing to the mixing of warm 925mb temperatures down from aloft.
North- northeast winds will help filter cooler air into the region today and Thursday with daytime highs in the low to mid 70's and overnight lows in the low 50's north to low 60's south.
829 AM MST Wed Nov 18 2020 High pressure ridge axis will be shifted east of Montana as a broad trough moves onto the Pacific Northwest coast today and across the northern Rockies Thursday. Pressure gradients will tighten along the Upper Yellowstone and Stillwater Valleys later this morning as lee- side troughing will develop. In addition, a cold front will move across the forecast area tonight and this will allow for some higher winds aloft to mix down ahead of the front today. Highs today will be well above normal with 50s to lower 60s for the lower elevations.
256 PM CST Wed Nov 18 2020 Strong ridging across the Central US and southerly mid-level flow from the Gulf of Mexico has resulted in another stretch of warm days across our region.
235 PM CST Wed Nov 18 2020 The axis of a broad upper level ridge spread across the CONUS has shifted to our east. Southerly surface flow today will veer to the southwest tomorrow, helping lift temperatures across the region into the low 80s by tomorrow afternoon.
Satellite showing cold unstable upper level trough moving into the Pacific northwest. As the cold front moves east clouds will increase and precipitation will overspread the forecast area. Expect a fairly good area of showers along the cold front later this morning into the afternoon.
138 PM MST Wed Nov 18 2020 Lowering heights will lead to cooler temperatures for Thursday. Highs will limited to around 50 degrees behind a cold frontal passage tonight.
A dying cold front may drop a few sprinkles across northern areas through this afternoon. Otherwise cooler and cloudier conditions will persist today, then clear skies and slowly warming temperatures are expected into the weekend. A decaying cold front will continue its trek through area today.
In the wake of the front, dew points have fallen into the lower to mid 60s. A strong high pressure that helped pushed the front across our region, will settle along the Appalachians and remain anchored for the next several days. This strong high pressure is creating an enhanced gradient across the region and leading to strong winds.
128 PM EST Wed Nov 18 2020 High pressure centered overhead slides east tonight into Thursday.
121 PM EST Wed Nov 18 2020 Canadian high pressure will build across the middle Atlantic through tonight. The high will then drift offshore but continue to extend westward across NC, while weakening, through the end of the week. Freeze Warning remains in effect for Cumberland, Wayne, and Ridging and nwly-nnwly flow aloft will prevail across cntl NC through tonight, with associated rising heights and subsidence that will maintain dry, stable, and mainly clear conditions. At the surface, 1038 mb high pressure centered over sern OH at 15Z -- with origins from the Yukon-- will build across the cntl Appalachians today and the middle Atlantic tonight.
103 PM EST Wed Nov 18 2020 Lake effect snow showers come to an end this morning with high pressure pushing into the region. Temperatures remain cold than average today, but trend warmer Thursday and really warm up for the weekend with broad ridging building in. By late afternoon, high pressure/ridging will slide eastward into the area through the day, however with cold NW flow still coming across the lakes, the low clouds will not clear till around sunset. High pressure will be overhead tonight with clear skies, light winds and perfect conditions for efficient radiational cooling. Warm air advection overnight Thursday along with some intermittent cloud cover will keep overnight lows at or above freezing across the region.
230 PM CST Wed Nov 18 2020 High pressure dominating the eastern U.
1140 AM CST Wed Nov 18 2020 (Today and tonight) South winds will continue to increase today as western trough takes shape and pressure falls occur across the high Plains.
Temperatures dipped into the 20s in most places earlier this morning, with the coolest valleys reaching the low 20s. Winds will remain from the southeast at 5-10 mph with 15 mph gusts today, but even with sunny skies and a southern breeze, temperatures will only make it to the low to mid 50s for most. Temperatures will fall to the low to mid 30s over the eastern half of our CWA and to the mid 30s to near 40 over the western half of the CWA as warm air tries advecting up the Mississippi Valley into the Ohio Valley. On Thursday strong high pressure will be centered over VA/NC as a cold front arcs from Hudson Bay through the upper Great Lakes to the Desert Southwest.
220 PM CST Wed Nov 18 2020 Tranquil weather continues across the Tennessee Valley region this afternoon, with strong subsidence from a high pressure ridge promoting a clear sky once again. After a very chilly start, (with many locations dipping below the freezing mark), winds have veered to the SE and helped to warm us into the lower 60s as of 20z. However, a light southerly flow should help to keep temperatures 5-10 degrees warmer tonight, with lows in the mid to upper 30s being common. High pressure centered over the Ohio Valley will shift east into the central and southern Appalachians including a south to southwesterly flow across the Deep South and Tennessee Valley region.
CMiller (Issued 223 AM CST Wed Nov 18 2020) Today through Thursday: High pressure will continue to slide off to our southeast exiting the Great Lakes Region this afternoon. The light winds early this morning will gradually become southerly as the high exits. As a low pressure system moves through Canada tomorrow, the pressure gradient will tighten across the Great Lakes Region. The strong southerly winds will result in some warm air advection that will bring some warmer temperatures into southern Wisconsin today and Thursday. Today high temperatures are expected to climb into the upper 40s to low 50s and Thursday could bring temperatures into the low 60s for southern Wisconsin.
1023 AM MST Wed Nov 18 2020 High pressure ridge axis will be shifted east of Montana as a broad trough moves onto the Pacific Northwest coast today and across the northern Rockies Thursday. Pressure gradients will tighten along the Upper Yellowstone and Stillwater Valleys later this morning as lee- side troughing will develop. In addition, a cold front will move across the forecast area tonight and this will allow for some higher winds aloft to mix down ahead of the front today. Highs today will be well above normal with 50s to lower 60s for the lower elevations.
115 PM MST Wed Nov 18 2020 Water vapor shows upper ridge over the Upper Midwest with trof moving into the western CONUS. Surface trof is moving through the central Dakotas. Gusty west winds will turn northwest on Thursday as upper wave crosses south central Canada and pushes a cold front through the Northern Plains.
126 PM MST Wed Nov 18 2020 Lowering heights will lead to cooler temperatures for Thursday. Highs will limited to around 50 degrees behind a cold frontal passage tonight.
Warmer temperatures are expected with highs in the 40s. Even warmer temperatures are forecasted for Thursday. Thursday night northern MN has some chance at freezing drizzle.
1239 PM EST Wed Nov 18 2020 High pressure will build into the region from the Ohio Valley today, then will become centered over the Carolinas through the end of the week and over the weekend.
122 PM EST Wed Nov 18 2020 Canadian high pressure will build across the middle Atlantic through tonight. The high will then drift offshore but continue to extend westward across NC, while weakening, through the end of the week. Freeze Warning remains in effect for Cumberland, Wayne, and Ridging and nwly-nnwly flow aloft will prevail across cntl NC through tonight, with associated rising heights and subsidence that will maintain dry, stable, and mainly clear conditions. At the surface, 1038 mb high pressure centered over sern OH at 15Z -- with origins from the Yukon-- will build across the cntl Appalachians today and the middle Atlantic tonight.
1143 AM CST Wed Nov 18 2020 The surface pressure gradient will increase today across the Midwest between the departing high pressure center across the Ohio River Valley and a developing trof of low pressure to the lee of the Rockies. The favorable wind direction should result in most locations topping out in the lower 70s! The current forecast is around the 75th percentile of all the guidance and one could argue to go higher (90-95th percentile) given past performance (verification) of these same conditions this fall season.
It will also bring warmer temperatures today to the areas where strong low level inversions limited temperatures yesterday. Late tonight, surface temperatures will fall below freezing in many areas while temperatures aloft will stay warm enough for a mix of sleet and freezing rain with the potential for enough ice to make roads icy. Somewhat cooler temperatures are expected behind the cold front on Thursday. Winds will be light and variable tonight until a cold front turns the winds to the west late tonight and Thursday morning. ICING: There is a chance of sleet and freezing after 06z tonight that will continue into Thursday morning.
Temperatures dipped into the upper 20s for many Middle Tennessee cities last night, and some areas that hadn't previously hit freezing finally did so.
341 PM EST Wed Nov 18 2020 Canadian high pressure will build across the area through tomorrow, with the high's center settling across the region into the weekend. There will be a threat for freezing temperatures and areas of frost on Thursday morning. Warmer temperatures return late this week and into the weekend.
1056 AM EST Wed Nov 18 2020 Canadian high pressure will build across the middle Atlantic through tonight. The high will then drift offshore but continue to extend westward across NC, while weakening, through the end of the week. Freeze Warning remains in effect for Cumberland, Wayne, and Ridging and nwly-nnwly flow aloft will prevail across cntl NC through tonight, with associated rising heights and subsidence that will maintain dry, stable, and mainly clear conditions. At the surface, 1038 mb high pressure centered over sern OH at 15Z -- with origins from the Yukon-- will build across the cntl Appalachians today and the middle Atlantic tonight.
NW flow will support seasonably cooler temperature through the remainder of the day. Building high pressure should gradually erode cloud cover, with dry conditions expected through tonight.
We extended the warning into Missouri than our what typical Red Flag Warning RH values would suggest, but with the high winds and grass being the main fuels we think they will dry out quickly today. Expect temperatures to climb into the low to mid 70s by the afternoon, making it probably the last day we get to these temperatures for a while.
The cold front has certainly made its presence known. Surface observations show dew points in the low to mid 60s and temperatures are in the mid 70s. Temperatures will be slow to moderate through the end of the week and will hold in the lower 80s for daytime highs and overnight lows in the lower 70s.
1205 PM EST Wed Nov 18 2020 High pressure to our west will slide closer and then sag southeast into the Carolinas on Thursday.
1126 AM CST Wed Nov 18 2020 (Today and tonight) Sunny and breezy today as the surface pressure gradient tightens in response to lee side troughing beneath the upper level zonal flow. With the low clouds returning tonight, lows temperatures should only fall into the lower 50s.
Strong high pressure will move from north northeast of the region this afternoon, to more toward the northeast through Thursday. Temperatures will continue to trend below normal this period, but with the flow more from the east on Thursday, readings will be a little warmer than today.
VFR conditions are expected to continue with high pressure continuing to dominate the forecast.
306 PM EST Wed Nov 18 2020 Lake effect snow showers come to an end this morning with high pressure pushing into the region. Temperatures remain cold than average today, but trend warmer Thursday and really warm up for the weekend with broad ridging building in. Overnight, as high pressure moves off the Mid Atlantic coastline tonight the flow will turn southerly. Warm air advection overnight Thursday along with some intermittent cloud cover will keep overnight lows at or above freezing across the region.
A mid to upper level ridge continues to build over the region through today and into Thursday. Meanwhile, surface ridging located over the Ohio River Valley continues shifting east through this evening eventually settling over the eastern seaboard. High temps today are expected to be in the mid to upper 60s across the CWA considering a cooler start to today with low temps this morning dropping into the upper 30s and low to mid 40s across the region.
225 PM EST Wed Nov 18 2020 Canadian high pressure will build across the middle Atlantic through tonight. The high will then drift offshore but continue to extend westward across NC, while weakening, through the end of the week. Ridging and nwly-nnwly flow aloft will prevail across cntl NC through tonight, with associated rising heights and subsidence that will maintain dry, stable, and mainly clear conditions. At the surface, 1037 mb high pressure centered along the OH/WV border at 19Z --with origins from the Yukon-- will build across the middle Atlantic through 12Z Thu.
Extra caution is advised today given the low humidity values and light to moderate northeasterly winds.
This ridge is bringing a rather dry air mass also into the forecast area. With high pressure in control both sfc/aloft and basically no low-level moisture noted on forecast soundings/time-height sections, expect VFR conditions to continue through the period. High pressure is centered over the Ohio Valley this morning and stretches from the Great Lakes to the northern gulf coast. As the ridge moves east the flow will become more onshore which will warm and moisten the area through the end of the week and into the weekend.
252 PM EST Wed Nov 18 2020 An upper-level ridge and associated subsidence will remain in place across much of the U.
549 PM EST Wed Nov 18 2020 High pressure to our west will slide closer and then sag southeast into the Carolinas on Thursday.
524 PM CST Wed Nov 18 2020 High pressure centered across the southeast to maintain southerly winds across the region through the terminal forecast period ending 20/00Z. /Tonight through Thursday night/ Nice warmer day for us with low 70s for an average. It will be a little warmer trend each morning especially climbing from 40s to 50s in the short term.
542 PM CST Wed Nov 18 2020 Strong ridging across the Central US and southerly mid-level flow from the Gulf of Mexico has resulted in another stretch of warm days across our region.
705 PM EST Wed Nov 18 2020 Latest RAP model has mid/upper ridging over the eastern US through Thu. Robust high pressure easing eastward across the Mid-Atlantic will keep a tight gradient across the waters overnight and into early Thu morning.
/Tonight through Thursday night/ Nice warmer day for us with low 70s for an average. It will be a little warmer trend each morning especially climbing from 40s to 50s in the short term.
409 PM MST Wed Nov 18 2020 Water vapor shows upper ridge over the Upper Midwest with trof moving into the western CONUS. Surface trof is moving through the central Dakotas. Gusty west winds will turn northwest on Thursday as upper wave crosses south central Canada and pushes a cold front through the Northern Plains.
The region will remain under ridging aloft through the short term. /28/ Tomorrow night through Wednesday: The forecast period starts off tomorrow night with surface ridging across the Southeast States beneath weak quasi-zonal flow aloft. Temperatures will gradually moderate with afternoon highs in the low to mid 70s.
It looks like the high will be at least 91 degrees, which breaks the old record from way back in 2019 of 86 degrees. Don't worry, cooler weather is on the way.
754 PM CST Wed Nov 18 2020 High pressure dominating the eastern U.
High pressure from the surface through the midlevels will remain in control of our weather tonight, and shift to our east tomorrow. Generally went with a persistence forecast, apart from yesterdays breezy winds, with temperatures expected to be just a degree or two cooler today compared to yesterday.
528 PM CST Wed Nov 18 2020 A Pacific cold front moving through WY this afternoon will move through wrn and ncntl Nebraska overnight tonight.
AN UPPER LEVEL TROUGH WAS WELL TO THE WEST-NORTHWEST. WITH A COLD FRONT TRAILING OFF SOUTHWESTERLY. CURRENTLY THE BULK OF THE CLOUDS AND PRECIPITATION WERE ALONG AND NORTH OF THE WARM FRONT AND WITH THE COLD FRONT. SOUTHEAST WINDS THIS MORNING WILL BECOME MORE SOUTHERLY AS THE DAY PROGRESSES AND A COLD FRONT APPROACHES THE REGION.
529 AM CST Fri Jan 23 2015 Issued update to extend the Winter Storm Warning and Winter Weather Advisory across eastern and central portions of the Permian Basin, the Western Low Rolling Plains, and the Lower Trans Pecos through 9 am CST. /ISSUED 415 AM CST Fri Jan 23 2015/ Snow continues to move across the Permian Basin and the Trans Pecos this morning with temperatures near or below freezing. The upper trough that is over the region and contributing to the snow is expected to move over eastern TX this afternoon. A broad upper trough will be over the eastern conus and Upper Midwest with a closed low taking shape off the coast of Mexico south of California beginning on Saturday.
632 AM EST FRI JAN 16 2015 A COLD FRONT WILL SLIDE ACROSS THE REGION TODAY. WEAK LOW PRESSURE CURRENTLY IN THE GULF OF MAINE WILL MOVE NORTHEAST INTO THE MARITIMES THIS MORNING. A STRONG COLD FRONT IS ALSO APPROACHING THE STATE FROM THE NORTHWEST AND WILL MOVE ACROSS THE AREA THIS MORNING. SNOW SHOWERS AND SNOW SQUALLS ARE ALSO POSSIBLE BEHIND THE COLD FRONT. HIGH PRESSURE BUILDING IN FROM THE WEST WILL BRING A MOSTLY SUNNY BUT BITTER COLD AND BREEZY DAY ON SATURDAY WITH HIGHS FROM JUST BELOW ZERO IN THE NORTH TO THE LOW TEENS ALONG THE DOWNEAST COAST. WINDS WILL DIMINISH AND CLOUDS WILL BEGIN TO INCREASE LATE IN THE DAY AS LOW PRESSURE APPROACHES FROM THE WEST.
A SE-MOVG COLD FRONT SHOULD REACH KRSL ~08Z BUT NO MORE THAN SW-NW WSHFT W/ ~13KT/15MPH SPEEDS WOULD SIGNAL THE FRONT'S ARVL.
HIGH PRESSURE OVER CENTRAL TEXAS THIS MORNING WILL BE MOVING OVERHEAD BY SUNDOWN.
919 AM EST FRI JAN 16 2015 A COLD FRONT WILL BRING SNOW SHOWERS TO THE REGION TODAY.
553 AM EST FRI JAN 16 2015 HIGH PRESSURE BUILDING INTO THE REGION TODAY WILL MOVE OFFSHORE SATURDAY.
1006 AM EST FRI JAN 16 2015 MID/UPPER LEVEL TROUGH IS MOVING OFF THE SOUTHEAST U. AREAS OF LOW CLOUDS REMAIN TRAPPED UNDER THE LOW LEVEL INVERSION. NORTHERLY WINDS WILL SHIFT TO NORTHEAST TONIGHT AND THEN EASTERLY SATURDAY AS HIGH PRESSURE MOVES BY TO THE NORTH.
Winds at ridge top level could reach up to 55 kts from the west today, with gusty winds up to 25 kts developing in some of the larger valleys by this afternoon, including airfield KBTM and possibly KMSO. A rain/snow mix is likely, though there is the potential for west central Montana valleys to see light freezing drizzle this morning, which could be a sneaky travel impact.
RIDGING INFLUENCES SFC/ALOFT SHOULD PROVIDE FOR VFR/SKC CONDITIONS WITH LIGHT SW-NW SFC WINDS THRU 17/12Z.
526 AM CST FRI JAN 16 2015 FOR 12Z TAFS /ISSUED 454 AM CST FRI JAN 16 2015/ WATER VAPOR SATELLITE DATA INDICATES THAT THE MID/UPPER-LEVEL TROUGH WHICH WAS LARGELY RESPONSIBLE FOR YESTERDAY'S WINTRY PRECIPITATION CONTINUES TO SHIFT EASTWARD OFF THE SOUTHEAST ATLANTIC COAST. THIS -- ALONG WITH THE ADVECTION OF DRIER AIR INTO THE REGION -- HAS ALLOWED FOR THE EROSION OF LOW STRATUS CLOUDS AND SUBSEQUENT DEVELOPMENT OF AREAS OF FREEZING FOG. HAVE ADDED PATCHY FREEZING FOG TO THE FORECAST FOR LOCAL RIVER VALLEYS ONCE AGAIN TONIGHT. EVEN WARMER TEMPERATURES ARE EXPECTED SATURDAY.
1045 AM EST FRI JAN 16 2015 HIGH PRESSURE BUILDING INTO THE REGION TODAY WILL MOVE OFFSHORE SATURDAY.
/ISSUED 410 AM EST FRI JAN 16 2015/ LATEST WATER VAPOR SATELLITE SHOWS THE MID LEVEL TROUGH AXIS ACROSS THE CAROLINAS STRETCHING SOUTHWARD INTO NORTHERN FLORIDA. AS THIS TROUGH PUSHES OFFSHORE THROUGH THE DAY. IT WILL ALLOW THE ASSOCIATED SURFACE COLD FRONT TO PUSH DOWN THE FLORIDA PENINSULA AND INTO THE AREA. SKIES SHOULD BEGIN TO CLEAR FROM NORTH TO SOUTH ACROSS THE AREA LATE TODAY AS DRY HIGH PRESSURE BUILDS ACROSS NORTHERN FLORIDA. EASTERLY FLOW WILL THEN QUICKLY RETURN WITH ATLANTIC COASTAL SHOWERS POSSIBLE FOR SATURDAY AS HIGH PRESSURE PUSHES EAST AND INTO THE WESTERN ATLANTIC.
647 AM EST FRI JAN 16 2015 HIGH PRESSURE BUILDING INTO THE REGION TODAY WILL MOVE OFFSHORE SATURDAY.
533 AM CST FRI JAN 16 2015 WATER VAPOR SATELLITE SHOWS A COUPLE OF SHORT WAVE TROUGHS THAT WILL TRACK ACROSS THE UPPER MIDWEST THROUGH SATURDAY. THIS WILL PRESENT PRECIPITATION TYPE PROBLEMS AS THE TOP LAYER THROUGH SATURDAY MORNING WILL HAVE ICE IN THE CLOUDS BUT THE SEPARATION FROM THE LOWER SATURATED LAYER WILL BE TOO FAR TO ALLOW A SEEDER/FEEDER MECHANISM TO WORK. THIS WILL LEAVE THE LOWER SATURATED LAYER WITHOUT ICE MAKING FREEZING DRIZZLE A POSSIBILITY. THIS WILL RESULT IN HAVING FREEZING DRIZZLE MENTIONED WITH BOTH OF THESE WAVES. THE PRECIPITATION CHANCES SATURDAY WILL TRANSITION OVER TO MAINLY DRIZZLE FOR MUCH OF THE AREA AS TEMPERATURES ARE EXPECTED TO CLIMB ABOVE FREEZING WITH UPPER 30S ACROSS THE SOUTHERN PARTS OF THE AREA.
245 AM PST FRI JAN 16 2015 HIGH PRESSURE AND OFFSHORE FLOW WILL CONTINUE THE ABOVE NORMAL TEMPERATURES THROUGH AT LEAST THE WEEKEND.
TROUGH STILL EXPECTED TO COME IN THIS AFTERNOON AND DRAG A FRONT THROUGH TONIGHT. TEMPERATURES WILL BE MILD WITH 40 DEG THRESHOLD NOT FAR FROM BEING REACHED ON SAT AND EVEN WARMER ON SUN IN SPITE OF PRECIPITATION AND CLOUD COVER.
THE FIRST OF THESE WAVES IS SET TO ARRIVE OVER THE HIGH PLAINS LATER TODAY. THE LACK OF ICE CRYSTALS IN THE FORECAST SOUNDINGS SUGGEST THAT FREEZING DRIZZLE IS ALSO POSSIBLE THIS AFTERNOON.
The biggest influence will be the thin layer of high clouds associated with a 100 kt west-to-east oriented subtropical jet on the southern flank of the trough. Temps at 850 mb are progged to warm by 3-4C from yesterday afternoon, which should yield surface temps 5-7F warmer today. We should not see temperatures dipping too far below the freezing mark across the CWA, even in the favored cold spots in low-lying areas and river valleys.
1011 AM EST FRI JAN 16 2015 A COLD FRONT WILL CROSS THE AREA TODAY.
1007 AM EST FRI JAN 16 2015 COLD FRONT PUSHED THROUGH SOUTH FLORIDA EARLIER THIS MORNING. AS THIS BOUNDARY AT THE LEADING EDGE OF HIGH PRESSURE PUSHES THROUGH THE REGION LATER THIS AFTERNOON INTO THE EVENING. IT WILL BE MOSTLY CLOUDY AND COOLER. /ISSUED 410 AM EST FRI JAN 16 2015/ LATEST WATER VAPOR SATELLITE SHOWS THE MID LEVEL TROUGH AXIS ACROSS THE CAROLINAS STRETCHING SOUTHWARD INTO NORTHERN FLORIDA. AS THIS TROUGH PUSHES OFFSHORE THROUGH THE DAY. IT WILL ALLOW THE ASSOCIATED SURFACE COLD FRONT TO PUSH DOWN THE FLORIDA PENINSULA AND INTO THE AREA. SKIES SHOULD BEGIN TO CLEAR FROM NORTH TO SOUTH ACROSS THE AREA LATE TODAY AS DRY HIGH PRESSURE BUILDS ACROSS NORTHERN FLORIDA. EASTERLY FLOW WILL THEN QUICKLY RETURN WITH ATLANTIC COASTAL SHOWERS POSSIBLE FOR SATURDAY AS HIGH PRESSURE PUSHES EAST AND INTO THE WESTERN ATLANTIC.
