332 PM EST Thu Dec 2 2021 The afternoon surface analysis shows High pressure in the Gulf of Mexico and low pressure to the north in Canada. Also given the mostly clear and calm conditions would be expected for many locations at least some ridge/valley splits would be possible, with lows in the low to mid 30s in some of the deeper valleys. Friday will be a split in terms of temperatures with mid to upper 60s in the southwest and northeast looking at highs in the low to mid 60s.
1223 PM EST Thu Dec 2 2021 Scattered showers and windy conditions can be expected today with a crossing cold front.
The only difference between Thursday and Friday will be the presence of a cold front. Because 850 mb temperatures will still linger around 15C and skies will be clear, temperatures behind the front should still be able to rise into the low 60s. Jaja A high pressure system originating from the Canadian Rockies will quickly traverse the northern CONUS.
Otherwise, this will be the warmest day as we experience a series of fronts bringing progressively cooler temperatures in the 7 day period. Highs tomorrow still well above normal in the lower 50s to lower 60s.
High pressure over the Southeast overnight will continue to slide eastward into the North Atlantic. While previous deterministic and ensemble models had some inconsistency in terms of the strength and location of the high over the weekend, there is now much better support for a stronger and southward solution.
A ridge remains over the area causing dry and stagnant conditions.
In the upper levels, a ridge will be over the deep south. A trough will be over the Northeast. At the surface, low pressure over the Northeast will move into the Atlantic tonight. Weak high pressure will be over the Southeast and Ohio Valley.
1015 AM MST Thu Dec 2 2021 Broad, flat upper ridging covers much of the CONUS, with northwest flow over the northern plains. A backdoor cold front is pushing into northeastern portions of the CWA, behind which winds are northerly and temperatures are in the 40s. Tonight, another cold front will cross our region, resulting in noticeably cooler temperatures for Friday (highs in the 40s).
High pressure will bring dry conditions through this weekend. High pressure continued to dominate the weather pattern across the western states during the afternoon hours. Over the next several a jumbled flow pattern of weak low pressure systems and light flow will be the main influence on Arizona weather. A pair of weak low pressure systems will move over or brush Arizona.
153 PM CST Thu Dec 2 2021 What a day! Is this summer? Sunny skies and temperatures soaring into the low 70s for almost everyone (it's always a little cooler on the Plateau). I have gone above guidance for highs tomorrow as a westerly mid-level pattern, coupled with more southerly boundary layer flow, should help us to get even warmer tomorrow.
With gusts now below 50 mph generally, the High Wind Warning is no longer need, and has been cancelled. With the cloud cover and winds overnight, temperatures were warmer than forecast, so have adjusted the temperatures trends today to better fit the observations. A weak cold front has worked into the east and with less wind, the east has cooled into the 30s.
1208 PM CST Thu Dec 2 2021 Today will continue to feel unusually warm for December, but will be a solid 10 degrees cooler than yesterday in most locations, with highs in the upper 30s to the NE and upper 40s in the SW. In addition, P-type could be of concern due to low-level and surface temperatures hovering near freezing. Freezing rain is not expected, but freezing drizzle and light snow could cause for slick roads overnight, particularly in our WI counties.
1144 AM CST Thu Dec 2 2021 (Today and tonight) Weak upper level ridging will remain over the area through tonight.
(This evening through Friday) High temperatures will continue to be well above average tomorrow as the mid-level ridge shifts off to the east. Southerly winds will persist through the day tomorrow until a weak cold front begins to move in tomorrow night across parts of NW Oklahoma. Low temperatures for tonight will be in the low 40s to low 50s across the area.
Tonight: A quick moving/weak clipper-type system is expected to pass to the southwest of the area, leading to a quick moving band of light snow to the northeast of the low. Enough moisture and forcing will be in place ahead of the trough, to produce isolated to scattered precipitation. Friday Night Through Thursday For Friday night, high pressure will build into the region as low pressure northeast of the state moves away.
This will help activate a warm front or like warm sector, as southwesterlies deepen across the PAH FA thru the day on Friday.
Meanwhile, an inverted trof will push east across the forecast area. Some snow may even mix in late this evening as temperatures fall to around freezing.
High pressure and an offshore flow will bring unseasonably warm temperatures to the area through Friday.
Temperatures will stay mild tonight with areas along and south of Interstate 70 falling into the mid and upper 40s, and locations north of the Interstate seeing lows in the low to mid 40s. A weak front will move through the region tomorrow bringing in slightly cooler air, but still well above normal high temperatures in the 60s.
544 PM CST Thu Dec 2 2021 FORECAST HIGHLIGHTS THE NEXT 7 DAYS: * Above normal temperatures Friday, albeit a bit cooler than today.
Forecast soundings suggest there may be some mixing in the lower-levels to make it more of a very-low stratus layer, but the probabilities for fog are high enough to include in the weather grids and our Hazardous Weather Outlook text and graphics.
The warmth continues with the continues Friday night with the light southerly flow and continued moistening up of the low levels.
655 PM EST Thu Dec 2 2021 High pressure continues to build in from the west. The high pressure center will build over the state through Friday. High pressure in place across the waters through the period will keep winds and seas light.
414 PM MST Thu Dec 2 2021 The broad upper level pattern is quite evident when looking at satellite as some high clouds are seen moving west to east across Wyoming and east to west across Arizona, indicative of high pressure sitting directly overhead. Perfect time to do the last bit of fall clean up before the weather pattern changes to a cooler and more unsettled pattern with hopes of precipitation in the forecast for the coming week. Until then, we remain in this quasi-zonal flow with a broad area of high pressure stretched across the Great Basin and western slope with a cut off low off the Baja coast and an active northern stream across the northern U. This is keeping our area in somewhat of a blocking pattern with not much change at least through the end of the week.
But, with the synoptic setup ill-defined/messy, hence the limiting factors feeding into the low PoPs/low accums.
/Issued 248 PM EST Thu Dec 2 2021/ Upper flow transitions from weak northwesterly through generally zonal to weak ridging as the region remains under the weak and somewhat progressive southern branch.
The cold front that was expected to move through this afternoon, was just north of the area around 1 PM.
304 PM CST Thu Dec 2 2021 FORECAST HIGHLIGHTS THE NEXT 7 DAYS: * Above normal temperatures Friday, albeit a bit cooler than today.
Very quiet tonight with broad high pressure slowly building over the region.
What a day! Is this summer? Sunny skies and temperatures soaring into the low 70s for almost everyone (it's always a little cooler on the Plateau). I have gone above guidance for highs tomorrow as a westerly mid-level pattern, coupled with more southerly boundary layer flow, should help us to get even warmer tomorrow.
210 PM MST Thu Dec 2 2021 The broad upper level pattern is quite evident when looking at satellite as some high clouds are seen moving west to east across Wyoming and east to west across Arizona, indicative of high pressure sitting directly overhead. Perfect time to do the last bit of fall clean up before the weather pattern changes to a cooler and more unsettled pattern with hopes of precipitation in the forecast for the coming week. Until then, we remain in this quasi-zonal flow with a broad area of high pressure stretched across the Great Basin and western slope with a cut off low off the Baja coast and an active northern stream across the northern U. This is keeping our area in somewhat of a blocking pattern with not much change at least through the end of the week.
Winds today will continue to taper off and Friday should be cooler with light winds as a transition to a more normal winter weather pattern gets started.
Minimal impacts on Friday and Friday night with high pressure passing over the area.
517 PM CST Thu Dec 2 2021 (This evening through Friday) High temperatures will continue to be well above average tomorrow as the mid-level ridge shifts off to the east. Southerly winds will persist through the day tomorrow until a weak cold front begins to move in tomorrow night across parts of NW Oklahoma. Low temperatures for tonight will be in the low 40s to low 50s across the area.
530 PM CST Thu Dec 2 2021 (This evening through Friday) It certainly does not feel like December today across west central Texas, as temperatures have soared into the lower to mid 80s across much of the area. Overnight lows will remain on the mild side, with temperatures ranging from the mid 40s in the Big Country to the lower to mid 50s elsewhere. A few of the high res models do generate some scattered showers across our southeastern counties as this disturbance skirts by.
226 PM PST Thu Dec 2 2021 Strong high pressure over the region maintains dry conditions along with mild afternoons and chilly mornings.
Winds will be light, despite a back door cold front sliding down the plains on Friday, turning winds around to the north and northeast.
341 AM EST Fri Dec 3 2021 Mainly dry weather is expected through Saturday as high pressure builds in.
230 AM CST Fri Dec 3 2021 A cold front will be pushing through the CWA during the day today allowing winds to shift to the north but the CAA will be delayed.
Today, expect a cold front, currently pushing south through Nebraska, to pass through the Panhandles during the daytime hours. That said, with the lowest RH values in the downslope regime south of the front displaced from the breezy winds north of the front, only wind-driven elevated fire weather conditions are expected in the northwestern Panhandles.
A warm front moving east across the area this afternoon has allowed for another warm day for parts of the area albeit not as warm as yesterday. A cold front over southern Alberta early this afternoon will push south and exit to our south tonight. Look for temperatures Friday to be much cooler than today.
Tonight Through Saturday Quiet weather conditions were ongoing across the Mid-South thanks to a large area of high pressure along the northern Gulf Coast. Anyways, warm air will remain in place as high pressure stays situated to the south.
1019 PM MST Thu Dec 2 2021 The broad upper level pattern is quite evident when looking at satellite as some high clouds are seen moving west to east across Wyoming and east to west across Arizona, indicative of high pressure sitting directly overhead. Perfect time to do the last bit of fall clean up before the weather pattern changes to a cooler and more unsettled pattern with hopes of precipitation in the forecast for the coming week. Until then, we remain in this quasi-zonal flow with a broad area of high pressure stretched across the Great Basin and western slope with a cut off low off the Baja coast and an active northern stream across the northern U. This is keeping our area in somewhat of a blocking pattern with not much change at least through the end of the week.
There may be a few sprinkles in the VCNTY of KDRT through 10Z as an upper level trough moves through, but not enough coverage or intensity to mention in the TAF.
1128 PM CST Thu Dec 2 2021 FORECAST HIGHLIGHTS THE NEXT 7 DAYS: * Above normal temperatures Friday, albeit a bit cooler than today.
A cold front will bring briefly cooler temperatures in the 40s Saturday.
The region will be between a trough of low pressure to the northeast, and high pressure over the eastern Gulf this morning. Through the day Today, troughing will be to the north, with high pressure becoming centered over central FL. Readings will be coolest near the coast due to relatively cooler coastal waters. Highs will be a few degrees cooler over inland NE FL as well, due to expected stratus slowing warming. For Tonight, high pressure ridge to the east will extend across the region, with a trough lingering to the north. Lows will range from the middle 40s to upper 40s inland, to the lower 50s along the coast.
/issued 655 PM EST Thu Dec 2 2021/ High pressure continues to build in from the west. The high pressure center will build over the state through Friday. High pressure in place across the waters through the period will keep winds and seas light.
130 AM EST Fri Dec 3 2021 Mainly dry weather is expected through Saturday under high pressure. Dry conditions will persist overnight and Saturday as high pressure remains the main feature.
VFR conditions expected at CHA and TYS through the period as high pressure is in control. There may be a brief period of MVFR fog at TRI later this morning but confidence is on the lower side due to the current temp/dewpoint spread.

High pressure will bring dry conditions through this weekend. Another warm and tranquil weather day on tap for Friday as high pressure continues to be the dominant feature impacting the US Southwest.
The record for MAF today (83F) was set back in 1954 with a very similar setup forecast as thermal ridge placement and magnitude of warm air within the boundary layer (+20C as well for that day as well) mixed efficiently under mostly sunny skies and westerly winds. Saturday will be cooler with highs in the 60s and low 70s for many under a cooler N/NW wind in-lieu of the front. Still, absolutely nothing to speak of regarding precipitation as drier air will actually press south beyond the cold front.
Lows tonight range from around 50 inland to the lower/mid 50s at the immediate coast, then lows Friday night will be just a bit warmer. Highs on Friday and Saturday will be in the lower to mid 70s.
1056 PM CST Thu Dec 2 2021 (This evening through Friday) It certainly does not feel like December today across west central Texas, as temperatures have soared into the lower to mid 80s across much of the area. Overnight lows will remain on the mild side, with temperatures ranging from the mid 40s in the Big Country to the lower to mid 50s elsewhere. A few of the high res models do generate some scattered showers across our southeastern counties as this disturbance skirts by.
Temperatures were mainly around 70 or the lower 70s, with the interior of Big Pine already haivng dipped to 64F before a northerly breeze of 3 mph kicked up the temperature a few degrees. 3 feet, which will are keeping the current higher high tide below any coastal flood statement thresholds in the lower and middle Keys. Continuing from the previous synopsis, a weak ridge of high pressure will continue to straddle the Florida Peninsula over the next several days.
But, with the synoptic setup ill-defined/messy, hence the limiting factors feeding into the low PoPs/low accums. At that point though, focus then turns to the next trough dipping into the Upper Midwest.
The elongated area of high pressure that has been in control for the last several days will continue to sit overhead through Saturday night, with generally zonal flow aloft.
Tonight: A quick moving/weak clipper-type system is expected to pass to the southwest of the area, leading to a quick moving band of light snow to the northeast of the low. Enough moisture and forcing will be in place ahead of the trough, to produce isolated to scattered precipitation.
High pressure centered to our south shifts slightly further east today. This allows the flow to become more west-southwest which in turn allows temperatures to be even warmer than yesterday. With the high shifting east the pressure gradient won't be as strong as yesterday so winds should be lighter through the day today.
The prolonged period of valley inversions will continue for southeast Oregon and southwest Idaho as high pressure supports calm and dry conditions. Surface wind speeds will begin to increase mid-day Saturday, along with showers for Baker County and west-central Idaho, as a low pressure system influences the forecast area.

911 PM CST Thu Dec 2 2021 (This evening through Friday) High temperatures will continue to be well above average tomorrow as the mid-level ridge shifts off to the east. Southerly winds will persist through the day tomorrow until a weak cold front begins to move in tomorrow night across parts of NW Oklahoma. Low temperatures for tonight will be in the low 40s to low 50s across the area.
What a day! Is this summer? Sunny skies and temperatures soaring into the low 70s for almost everyone (it's always a little cooler on the Plateau). I have gone above guidance for highs tomorrow as a westerly mid-level pattern, coupled with more southerly boundary layer flow, should help us to get even warmer tomorrow. Models hint at this idea of a weak boundary trying to slip southward into the region, potentially sparking a few showers on Saturday, before lifting northward again as a warm front.
Look for overnight lows to range from the lower to upper 50s across the area, which is around 15 to 20 degrees above seasonable normals.
At the surface, cold front is making its way through the region, with low pressure over southeastern NE and high pressure pushing in from northern MT. Cold high pressure will sink into the northern plains today, resulting in daytime highs near or below current temperatures across northwestern SD. Overnight, strong 650-750 mph frontogenesis will develop between the exiting high pressure and incoming low across ND and northwestern SD. HRRR is hinting at fog around the Black Hills Saturday morning, which is supported by the easterly surface winds, and would be freezing fog with temperatures then in the 20s.
Snow levels will start to lower and combine with incoming moisture off the Pacific to bring snow to valleys and mountains alike (most likely along and north of the Highway 2 corridor).
Upper-level flow across the CONUS is nearly zonal early Friday morning, with the exception of trough moving off the East Coast. Despite the front sliding south through the day, temperatures still look well above normal, with highs in the low to mid 60s, and a close to normal diurnal temperature trend. For Saturday, cooler and drier high pressure will build into the Great Lakes area. Since this is really just giving us a glancing hit of cooler/drier air, temperatures for Saturday still look slightly above normal. Highs should top out in the low to mid 50s for most areas but far northern and northeastern MO may be stuck in the upper 40s.
531 AM EST Fri Dec 3 2021 Mainly dry weather is expected through Saturday as high pressure builds in.
The ample sunshine, and persistent southwest downsloping/warming winds will give us another very warm day for this time of year with highs mainly in the low to mid 80s. Record heat is again possible at both San Angelo and Abilene, although not a slam dunk as the records today are a few degrees warmer with 87 at Abilene, and 88 at San Angelo.
After a fairly mild start with readings in the 30s, should see temps top out from the lower-mid 40s north of I-90, to the lower 50s south of Highway 18. Moisture is somewhat limited below 5kft through late tonight, but several models point to a potential for a few flurries working into the Highway 14 corridor west of Brookings by daybreak Saturday.
early this morning, high pressure over the Gulf of Mexico has begun to contract and shift more toward the eastern gulf. Aloft, mid and upper low shifting into the Panhandles Region has allowed for more southwesterly flow, with a fetch of moisture moving in. As the high shifts away today, moisture will continue to increase out ahead of a frontal boundary approaching from the plains.
Models are fairly consistent in bringing an approaching cold front through parts of northeast Oklahoma to the north of I-44 mid to late afternoon.
Today we are looking to remain dry and unseasonably warm once again as high pressure dominates.
317 AM CST Fri Dec 3 2021 Relatively cooler conditions set in through the weekend, although above normal temperatures are expected to continue before more seasonal air arrives to start the next work week. The upper air pattern features broad northwesterly flow across the northern half of the CONUS with the ridge firmly in place over the Desert Southwest.
High pressure and an offshore flow will bring unseasonably warm temperatures to the area once again today.
This means a chance for rain and snow showers and much cooler temperatures. High pressure is evident on satellite this morning and this system will bring nice weather to the area.
919 AM EST Fri Dec 3 2021 Mainly dry weather is expected through Saturday as high pressure builds across the Ohio Valley.
522 AM CST Fri Dec 3 2021 High pressure builds in from the northwest today bringing dry but cooler conditions. Winds will become breezy out of the southeast Saturday afternoon on the edges of the aforementioned warm front. The period begins Saturday night with an area of low pressure over the CWA with WAA snow mostly impacting most of ND.
Winds will increase and become northwesterly by late this morning as a high approaches from the west with temperatures about the same as or just a few degrees cooler than yesterday. Saturday's highs will be right around average in the low to mid 30s for the first weekend of December after a relatively warm week.
Primary aviation concern is the arrival of a cold front which will cause winds to veer to north-northeasterly at all sites Friday afternoon, with DHT and GUY also likely to see gusts above 25 knots as well. Today, expect a cold front, currently pushing south through Nebraska, to pass through the Panhandles during the daytime hours. That said, with the lowest RH values in the downslope regime south of the front displaced from the breezy winds north of the front, only wind-driven elevated fire weather conditions are expected in the northwestern Panhandles.
650 AM EST Fri Dec 3 2021 Mainly dry weather is expected through Saturday as high pressure builds in.
Low pressure passing by well to the north will drag a cold front through southern Wisconsin later today, breezy northwest winds bring cooler conditions tonight into Saturday.
Weak high pressure situated over the northern Gulf Coast has kept winds out of the north to northeast.
Much weaker flow aloft across the southern half of the country with a cut off (dry) upper low located across the desert southwest. A cooler day is in store today post frontal with the airmass a mix of Canadian and Pacific air. Cooler. Despite the return to southerly surface flow, a temperature warm up will be offset as cooler air is recycled back northward from the previous days cold front.
410 AM CST Fri Dec 3 2021 High pressure builds in from the northwest today bringing dry but cooler conditions. Winds will become breezy out of the southeast Saturday afternoon on the edges of the aforementioned warm front. The period begins Saturday night with an area of low pressure over the CWA with WAA snow mostly impacting most of ND.
