1229 PM PST Wed Dec 18 2024 The passage of a cold front today will create wind gusts as high as 60 mph across the Spokane Area, Palouse and Columbia Basin. The cold front is passing across the region this morning mixing down much stronger winds aloft that has resulted in widespread wind gusts of 50-60 mph across the Spokane Area, Palouse, and into portions of the Idaho Panhandle. Winds are on track to decrease into the afternoon as the low level jet with stronger winds aloft shift east of the region. Drier air behind the cold front has shut off the precipitation across the Cascades aside from a Puget Sound Convergence Zone (PSCZ) just north of Stevens Pass. /SVH 18Z TAFS: A rigorous cold front will deliver gusty west to southwest winds across the region.
- Cooler and breezy today. - Temperatures at or below freezing late tonight and Thursday morning. (This evening through Thursday) This afternoon, a cold front that move through the region overnight is continuing southward through south Texas. By this evening, a 1032mb high pressure center will move southward and settle in across west central Texas. This combination should result in ideal radiational cooling conditions and cause temperatures to fall to around freezing for most locations. The area of high pressure is expected to move eastward tomorrow with light southwesterly return flow.
110 PM EST Wed Dec 18 2024 High pressure and weak coastal troughing along with unseasonably warm temperatures will be giving way to a cold frontal passage tonight into early Thursday.
This morning met us with warmer-than-expected temps for many areas, and we are adjusting the forecast warmer for the highs today as a result.
1209 PM EST Wed Dec 18 2024 High pressure and weak coastal troughing along with unseasonably warm temperatures will be giving way to a cold frontal passage tonight into early Thursday.
Fast moving clipper trough will move into the Dakotas tonight and then off into MN/IA tomorrow, with a fairly broad swath of snow for our region.
(18Z TAFS) A cold front approaching from the north moves through the area late this afternoon into the evening hours and will be accompanied by mainly isolated showers/storms over a portion of the area. The passage of the eastern states upper trof is quickly followed by another upper trof which advances across the northern/central Plains then amplifies while moving into the eastern states through Thursday night. Highs on Thursday mainly range from the lower 60s inland to the upper 60s/near 70 closer to the coast. Thursday night will be cold with lows ranging from the mid to upper 30s inland to the lower 40s closer to the coast.
1017 AM EST Wed Dec 18 2024 High pressure and weak coastal troughing along with unseasonably warm temperatures will be giving way to a cold frontal passage tonight into early Thursday.
1153 AM CST Wed Dec 18 2024 The main adjustment to the forecast this morning was to adjust temperatures to better reflect current observations with the passing cold front. Recent surface analysis depicts a cold front passing across the local area around 1030AM, with the front located roughly from Nacogdoches to Shreveport to El Dorado. Kovacik (18Z TAFS) A NE to SW band of SHRA will continue to shift SE through the afternoon across NCntrl LA along a cold front, with the rains diminishing at MLU by 20Z.
1110 AM CST Wed Dec 18 2024 Updated at 1107 AM CST Wed Dec 18 2024 - Colder today behind cold front with gusty northerly winds.
As we sit on the south side of the ridge, a slight uptick in moisture will be ushered in tonight helping in the production of more light shallow showers. Overnight, due to the warmer water temperatures being similar to the dew point values, dense fog could appear in the deep Gulf waters reducing visibilities to 1 mile or less. Late tomorrow, a weak cold front is expected to move through the Keys as an upper-level trough becomes negatively titled across Florida.
Temperatures for most end up near freezing with a few spots in the upper 20s.
250 PM CST Wed Dec 18 2024 - Warmer and breezy Thursday.
1143 AM CST Wed Dec 18 2024 - Temperatures will be warmer than average to much warmer than average through this forecast period. Temperatures will warm to slightly warmer than normal for mid-December. Thursday, the previously mentioned weather system will move off to the east sending a cold front into the Panhandles around mid-day, but not before temperatures warm into the upper-50s to low-60s.
121 PM MST Wed Dec 18 2024 KEY MESSAGES: - High pressure bring potential for fog and low clouds to develop Thursday into the weekend.
Dry, abnormally warm conditions are in place as an unseasonably strong ridge of high pressure builds into our region. The strong ridge with ample sunshine has already helped to boost temperatures into record territory this afternoon as temperatures climb into the upper 70s to low 80s. Unseasonably strong ridging will be in place through the end of the week with 500 mb heights generally ranging between 582-586 dm.
540 PM CST Wed Dec 18 2024 (00Z TAFS) A cold front moving south through the area this evening will be accompanied by a ceiling lowering to IFR/MVFR levels across much of the area, along with a few evening sprinkles. The passage of the eastern states upper trof is quickly followed by another upper trof which advances across the northern/central Plains then amplifies while moving into the eastern states through Thursday night. Highs on Thursday mainly range from the lower 60s inland to the upper 60s/near 70 closer to the coast. Thursday night will be cold with lows ranging from the mid to upper 30s inland to the lower 40s closer to the coast.
740 PM EST Wed Dec 18 2024 A cold front will sweep across our area tonight.
501 PM CST Wed Dec 18 2024 (Tonight through Thursday night) At time of writing, a cold front is currently draped over our northern CWA, bringing isolated rain showers along and ahead of the boundary. Behind today's cold front, cold and dry air will settle into the region, bringing seasonably cool conditions. Overnight lows will fall into the 40s across most areas, with slightly warmer temperatures near the coast, where lows will hover around the low 50s. Northerly winds will continue to reinforce the cooler and drier air. Thursday night, lows will dip into the 40s across the Victoria Crossroads and much of the Coastal Plains, while the Brush Country and immediate coast will see lows in the low 50s.
(Tonight) The surface cold front that brought showers and storms to the Tennessee Valley earlier today is progressing over the southeastern portion of our area at present. Cooler and drier conditions will be ushered into the region in the wake of this cold front, with low temperatures forecast to dip into the mid to upper 30s later tonight.
112 PM PST Wed Dec 18 2024 Gusty north winds will continue along the Lower Colorado River Valley this afternoon, especially in the vicinity of Laughlin and Bullhead City. Winds will gradually diminish this evening as ridging continues building over the area.
516 PM CST Wed Dec 18 2024 Cooler temperatures will remain in place through the weekend with morning lows in the 20s and 30s.
It was also a touch cooler than yesterday, with temperatures as of 3 PM mostly in the mid to upper 30s. Ahead of the low overnight into early Thursday, expect strong southerly winds and warm air advection to help get temperatures into the 40s to lower 50s before noon. However, a strong cold front will push through during the day, bringing even stronger westerly to northwesterly winds (and cooler air) to the area.
543 PM CST Wed Dec 18 2024 - Warmer and breezy Thursday.
428 PM MST Wed Dec 18 2024 - High pressure brings the return of quiet weather along with a warming trend during the remainder of the week and into the weekend.
633 PM CST Wed Dec 18 2024 Through Thursday: A cold front continues to push across the area today, now extending from near Natchez to near Meridian.
517 PM CST Wed Dec 18 2024 (Tonight) A cold front is currently pushing through the area and bringing a more unsettled patterned for the remainder of the day. Tonight, cold air advection following the cold front should help to quickly drop temperatures back to more seasonal levels (in the mid- upper 30s) under mostly cloudy skies.
431 PM MST Wed Dec 18 2024 - Gusty winds will persist over the higher terrain tonight, however, remain below High Wind Warning criteria. With the departure of an upper trough to our east, we have observed a return to more zonal flow today. However, in its wake, a fast moving upper trough and strong jet have been moving east/southeast across the region. Given the higher likelihood of this occurring, don't anticipate the need for any High Wind headlines at this time. Do think a few gusts up to 50 to 60 mph will be observed over the higher terrain tonight, especially the central mountains and Ramparts.
* Cooler temperatures return Thursday and continue into the weekend.
927 PM EST Wed Dec 18 2024 * Cooler temperatures return Thursday and continue into the weekend.
444 PM MST Wed Dec 18 2024 Updated at 414 PM MST Wed Dec 18 2024 - Dry weather will continue with light winds and temperatures well above average A weak cold front arrived this morning with enough cooling to knock our temps down about 5 to 10 degrees, but temperatures will recover for tomorrow. High pressure aloft will gradually build across the Western CONUS through the weekend.
602 PM PST Wed Dec 18 2024 Gusty north winds will continue along the Lower Colorado River Valley this afternoon, especially in the vicinity of Laughlin and Bullhead City. Winds will gradually diminish this evening as ridging continues building over the area.
526 PM CST Wed Dec 18 2024 (Tonight through Thursday night) Key Messages -Breezy and gusty behind the passage of the cold front -Overnight lows in the mid 30s for the Hill Country and southern Edwards Plateau with 40s elsewhere -Dry and cooler for the rest of this afternoon into Thursday night A cold front moved across most of South Central Texas from this morning into early afternoon. The front brought cooler temperatures (50s) across the Hill Country and (60s) the I-35 corridor as the frontal boundary pushed across the local area. Dry and cooler weather conditions are in store for Thursday across South Central Texas. Thursday's night lows are forecast to be warmer than those of Wednesday, ranging from the lower to mid 40s across the Hill Country to upper 40s and lower 50s across the coastal plains and Rio Grande.
532 PM CST Wed Dec 18 2024 - Cooler and breezy today. - Temperatures at or below freezing late tonight and Thursday morning. (This evening through Thursday) This afternoon, a cold front that move through the region overnight is continuing southward through south Texas. By this evening, a 1032mb high pressure center will move southward and settle in across west central Texas. This combination should result in ideal radiational cooling conditions and cause temperatures to fall to around freezing for most locations. The area of high pressure is expected to move eastward tomorrow with light southwesterly return flow. (Thursday night through next Wednesday) A ridge across the southwestern U.
A little lake effect (and even some patchy freezing drizzle over the higher terrain of Cambria and Somerset Counties) will last through about sunrise.
- Some locations across western North Texas will see temperatures near or below freezing Thursday morning.
This is thanks to a backdoor cold front from New Mexico that came through the area late this morning. The above normal temperatures and near to record temperatures are forecasted to stick around thanks to the broad area of high pressure that is dominating the area.
Much cooler temperatures remain on the horizon by the weekend.
404 PM MST Wed Dec 18 2024 - High pressure brings the return of quiet weather along with a warming trend during the remainder of the week and into the weekend.
723 PM EST Wed Dec 18 2024 Rain showers end tonight with drizzle/freezing drizzle across the mountains.
206 PM MST Wed Dec 18 2024 - Gusty winds will persist over the higher terrain tonight, however, remain below High Wind Warning criteria. With the departure of an upper trough to our east, we have observed a return to more zonal flow today. However, in its wake, a fast moving upper trough and strong jet have been moving east/southeast across the region. Given the higher likelihood of this occurring, don't anticipate the need for any High Wind headlines at this time. Do think a few gusts up to 50 to 60 mph will be observed over the higher terrain tonight, especially the central mountains and Ramparts.
521 PM CST Wed Dec 18 2024 - Pleasant conditions tomorrow ahead of a weak cold front later in the day.
935 PM EST Wed Dec 18 2024 Cooler air will move into the region behind a cold front today and into Thursday.
Gradual improvement is expected through the day, but given that the cold front only slowly moves through by tomorrow night, this will be a slow process taking much of the day. Once the front moves through, cooler and drier weather should alleviate any visibility concerns, but winds and seas will gradually build.
Fair weather continues thru the week under high pressure, but becomes more active this weekend as a series of quick moving features bring low probability of precipitaton to northern Nevada. Tonight through Thursday night High pressure under an upper ridge continues to influence the western U. This subsequently flattens the ridge though sensible weather remains unchanged other than an increase in cloud cover along the ID/OR borders with mid level clouds becoming more prevalent.
538 PM CST Wed Dec 18 2024 (This evening through Thursday night) The incoming cold front is knocking on our northwestern doorstep this afternoon.
The low stratus will likely continue to surge SSW into the region and encompass much of west Tennessee during the overnight hours. The enhanced cloud cover would act to stabilize temperatures from falling to the freezing mark and also limit fog potential. Temperatures will fall into the 30s areawide, but should remain just above freezing. AC3 Cooler temperatures will remain in place through the weekend with morning lows in the 20s and 30s.
Line is associated with a front strung out ahead of a positively tilted mid level trof swinging through the MS valley. With no real forcing associated with the trof or front, expecting a slow decrease in both coverage and intensity of any showers/storms with the front through the evening. Surface winds will switch around to the NW behind the line but given the orientation of the trof, winds aloft will remain out of the SW which will serve to slow the moisture scour thus clouds may hang in through Thu AM. Main dry push will occur through the morning on Thursday as the cooler and drier airmass filters in. Dewpoints will begin to drop overnight and through the day tomorrow as the upper trof sets up over the Great Lakes and arctic high shifts Southeast headed into the weekend.
1115 PM CST Wed Dec 18 2024 (This evening through Friday) To begin the period, rainfall associated with a cold front has now moved east and south of the state bringing calm and drier conditions to state.
Temperatures will continue to fall behind the departing cold front to around freezing by Thursday morning.
1036 PM MST Wed Dec 18 2024 - Gusty winds will persist over the higher terrain tonight, however, remain below High Wind Warning criteria. This event looks brief as the trough axis passes to the north and downward forcing is helping to spread winds down the eastern slopes. -KT With the departure of an upper trough to our east, we have observed a return to more zonal flow today. However, in its wake, a fast moving upper trough and strong jet have been moving east/southeast across the region. Given the higher likelihood of this occurring, don't anticipate the need for any High Wind headlines at this time. Do think a few gusts up to 50 to 60 mph will be observed over the higher terrain tonight, especially the central mountains and Ramparts.
Warmer air will return to the region on Thursday. Below normal daytime highs are expected for Kansas on Friday followed by a warmer temperatures as upper ridging quickly builds over the region for the weekend.
Most locations see morning temperatures fall into the 30s with areas of below freezing temperatures across the northern half of the area. A weak upper-level trough passes to the north of the region late this afternoon and evening. This trough acts to push a weak cold front south through the region tonight. Despite the front, Friday morning temperatures start near to slightly warmer than they did this morning. Light north winds and sunny skies during Friday afternoon will push in cooler weather.
1021 PM MST Wed Dec 18 2024 Updated at 956 PM MST Wed Dec 18 2024 - Dry weather will continue with light winds and temperatures well above average A weak cold front arrived this morning with enough cooling to knock our temps down about 5 to 10 degrees, but temperatures will recover for tomorrow. High pressure aloft will gradually build across the Western CONUS through the weekend.
1120 PM CST Wed Dec 18 2024 - Warmer and breezy Thursday. As these features move eastward Thursday we'll see southerly flow increase ahead of the upper trough leading warm advection across the area. This will help Thursday high temperatures climb into the low to mid 50s across eastern KS and western MO. This will lead to temperatures climbing into the lower 50s by the 25th. This leads to the low probabilities of precipitation which are mainly confined to our eastern/ southern zones.
We'll monitor for the potential of very localized elevated fire weather conditions with the combination of the lower humidity and these modest northeasterly breezes.
1035 PM CST Wed Dec 18 2024 - Pleasant conditions tomorrow ahead of a weak cold front later in the day.
126 AM EST Thu Dec 19 2024 A mix of freezing drizzle, drizzle, or light snow showers in/near the mountains overnight. This precipitation will fall as drizzle, freezing drizzle, or some light snow. With a light glaze of ice possible in the higher terrain of the northern West Virginia mountains, will continue with the Winter Weather Advisory. A high pressure system will build in later this morning, bringing an end to the upslope precipitation. A weak clipper system will drop into the area from the lower Great Lakes Friday, bringing support for snow showers across the region, with upslope snow showers expected in the mountains.
The cold front has moved south of the area this evening, but a few very light showers continue mainly in the southeast.
- Strong cold front late week will bring below normal temps for Friday into the weekend with dry weather persisting. If fog does happen to develop, will also need to monitor for freezing fog for locations that drop below freezing early tomorrow morning.
- Warmer and breezy today. Turning colder tonight into Friday night behind a cold front.
- Temperatures at or below freezing late tonight and Thursday morning. (Today and tonight) A cold morning across the area with temperatures at or below freezing across much of the area, the coldest being Sterling City at 25. However, expect warmer temperatures today with highs in the mid 60s to lower 70s. Another chilly night with lows in the 30s, with low lying areas and river valleys in the lower 30s.
We will likely see some pockets of freezing fog and/or low clouds. Temperatures will be a bit cooler the next couple of days especially where inversions and/or low clouds are slow to mix out.
Dry day today with cooler temperatures. We will be transitioning from the small trough that gave us yesterday's weather to the larger trough system whose center axis will be directly over Tennessee by Friday morning. We'll be transitioning from the mild 60s and rain showers the last several days to a drier and cooler pattern to come. Expectation is for the low clouds to scatter out around noon time giving us a bit of sunshine before sunset.
- Warm with another weakening cold front moving through the region today.
1256 AM CST Thu Dec 19 2024 The cold front has moved south of the area this evening, but a few very light showers continue mainly in the southeast.
Tonight: Ridge of high pressure will be over the area but then quickly shifts off to the east. Lows will be in the lower to mid 20s. The NAM is a bit farther north taking the low across southern WI. In our forecast area, light snow accumulations of around an inch in nw IL along the Highway 20 corridor, with less than one-half inch elsewhere across roughly our northeast half. Highs will range from the lower 30s in far nw IL to the lower 40s south. Thursday night: Cold front sweeps across our area with light snow or flurries gradually ending in our east.
242 AM CST Thu Dec 19 2024 - Cooler weather is expected for the end of the week and weekend.
Cloud cover that developed in the wake of last night's cold front continues to erode. Breezy southerly wind develops late tonight and becomes westerly by tomorrow afternoon as yet another cold front moves through the area.
1140 PM CST Wed Dec 18 2024 (06Z TAFS) A cold front moving south through the area will be accompanied by a ceiling lowering to IFR/MVFR levels across much of the area. The passage of the eastern states upper trof is quickly followed by another upper trof which advances across the northern/central Plains then amplifies while moving into the eastern states through Thursday night. Highs on Thursday mainly range from the lower 60s inland to the upper 60s/near 70 closer to the coast. Thursday night will be cold with lows ranging from the mid to upper 30s inland to the lower 40s closer to the coast.
Cooler air will continue to ooze in on a weak north wind overnight under persistent cloud cover. Anticipate temperatures slowly dropping into the lower and mid 30s by dawn, coolest northwest. A cold front is located in southeast KY late this afternoon and will exit into VA shortly. However, even with a ridge building in, it might be difficult to shake the low clouds. With warm air advection underway, this will probably allow for at least some modest ridge/valley temperatures differences. The upper flow pattern across the CONUS to begin the extended will feature strong troughing in place over the eastern quarter of the country, with strong ridging situated over the Rocky Mountains and desert southwest.
924 PM MST Wed Dec 18 2024 - High pressure brings the return of quiet weather along with a warming trend during the remainder of the week and into the weekend.
- Risk for freezing drizzle in the mountains of WV overnight.
Breezes have taken on a northerly component along the Lower Keys with east to southeast breezes still transitioning along the Middle and Upper Keys. This weakly cyclonic flow has allowed temperatures to already approach observed dewpoints in the lower 70s making for a muggy start to the night. The big story in the short term is the developing fog threat ahead of the incoming cold front. 41 inches (easily surpassing the highest recorded for this evening). In fact, in the absence of ground truth, satelitte observations would suggest its already ongoing in the western Straits of Florida and outer Gulf waters with another wave approaching the distant Gulf waters north of the Lower Keys. From synopsis, high pressure over the North Atlantic will continue sliding farther east loosening its grip across the Florida Keys.
- Strong cold front late week will bring below normal temps for Friday into the weekend with dry weather persisting.
High pressure will continue to build into the area through tonight. Quiet weather Thursday with high pressure in control. High pressure and dry weather return for the weekend.
