316 AM CST Tue Feb 25 2025 Forecast discussion for routine morning forecast issuance - A mix of light snow, drizzle and freezing drizzle could produce hazardous travel late tonight and Wednesday morning. Even though air temperatures may be a little above freezing in central and east central Wisconsin, drizzle may freeze on the pavement that is cold from the below normal temperatures over the last month.
Cloud cover will being to decrease across the southeast region this afternoon allowing for afternoon highs peaking in the low 70s areawide. Sfc ridging will begin to shift east into the region tonight, keeping weather conditions quiet across our forecast area. Our next chance for rain will likely start late Wednesday night as global guidance highlights an upper trough along with an associated sfc cold front over the Central Plains pushing southeast towards the southeast region. This sfc cold front will allow for temperatures to drop back down to seasonal norms for the remainder of the week.
The NBM came in with cooler temperatures than yesterday across the board, ranging from 1 to 6 degrees. While the eastern Panhandles should be cooler than yesterday by a few degrees, thinking that the rest of the Panhandles will see similar temperatures if not a couple degrees warmer. A cold front will move into the Panhandles tonight with current guidance suggesting soon after Midnight. With all that said, if the cold front moves in quicker than currently anticipated, then these strong winds and potentially elevated fire weather conditions would likely be realized further south than the Panhandles since this hinges upon the intersection of the 850mb jet overhead with sunny skies and sufficient mixing. Winds will gradually weaken through the afternoon as clouds move in, the surface pressure gradient slightly weakens, and the low-level jet moves off to the south.
- A weak cold front will bring an area of rain to the Quad State Wednesday afternoon and night. At the surface a weakening trough will move into the Quad State today before washing out. Winds will shift toward the WNW behind the trough mid to late morning. Highs will be a few degrees warmer, generally from the upper 50's across the northeast to the mid to upper 60's south and west. A cold front will bring chances of rain showers Wednesday afternoon and night.
608 AM EST Tue Feb 25 2025 Weak high pressure will continue to foster a warmup over the next few days.
- Slightly cooler Wednesday, but warming to end the week with dry conditions remaining.
Then, weak high pressure will build over NC from the Gulf and Southeast states tonight and Wednesday, before pushing offshore late Wednesday.
- Weak cold front on Wednesday with a chance for a few showers and slightly cooler temperatures. Continued the trend of forecasting warmer than guidance for at least one more day.

1106 AM CST Tue Feb 25 2025 (Rest of Today) Another tranquil/seasonably warm day is expected across the mid TN Valley for this Tue, as high pressure at the sfc remains layered over the western/central Gulf states. Current temp trends have already rebounded into the lower/mid 50s and with low-level flow veering to the west, highs later today should be able to easily climb into the upper 60s/perhaps 70F for most spots.
The one exception continues to be the Malheur River where mild temperatures yesterday flushed out the lower elevation snow pack.
228 PM CST Tue Feb 25 2025 - Early spring weather continues this afternoon, followed by a weak cold front and possible light rain showers overnight. - Above normal temperatures are on tap for the remainder of the week with highs generally in the low 60s.
- Weak cold front on Wednesday with a chance for a few showers and slightly cooler temperatures.

334 PM EST Tue Feb 25 2025 Weak high pressure will continue to foster a warmup over the next few days.
Cloud cover and slightly cooler air from a cold front that moved through last night will keep temperatures mostly at or below 70 today. High pressure builds in and temperatures quickly rebound tomorrow with upper 70s low 80s expected through the end of the week.
A seasonably chilly night is on tap with temps bottoming out in the lower to mid 30s amidst increasing cloud cover. For locales where it stays dry through the afternoon, which is favored across parts of N KY, temps should reach into the lower to mid 60s. Cold frontal boundary will begin to move through the ILN fa Wednesday night.
Light snow will continue to fall along the higher elevations today. -Wilson /Issued 956 AM MST Tue Feb 25 2025/ - Meteorological Overview: A Pacific cold front continues to move from west to east across the CWA this morning. A few scattered snow showers continue tonight, but overall a drying trend begins, as an upper level ridge of high pressure starts to build over the CWA on Wednesday.
1253 PM EST Tue Feb 25 2025 Weak high pressure will continue to foster a warmup over the next few days.
This supports a surface cold front coming in from the northwest to southeast through the morning hours. Some light snow for the western mountains, roughly 2 to 4 inches (60-80%) remaining mainly dry in the lower valleys west of the Divide through Wednesday morning. Otherwise, cooler temperatures Tuesday and Wednesday 5 to 10 degrees across the CWA, especially east of the Divide. Upper level ridging starts to build in into Wednesday with increasing convergence aloft that will give way to dry conditions and a warming trend through the end of the work week and into the weekend.
1041 AM MST Tue Feb 25 2025 - A cold front moves through today and will bring 2 to 4 inches of snow to the higher elevations of the northern and central mountains and Flat Tops.
(This afternoon through Wednesday) A dry and seasonably warm afternoon is underway as high pressure, centered over the northwestern Gulf, builds eastward across the Southeast. The result is beautiful weather conditions across Central Alabama with a sunny skies, low humidity, and highs in the lower 70s. Expect lows in the lower to mid 40s for most areas with some upper 30s possible in the north. The low-level ridge axis becomes aligned to the east of the area tomorrow with winds shifting to the southwest.
239 PM CST Tue Feb 25 2025 Updated at 234 PM CST Tue Feb 25 2025 -Above normal temperatures will continue through Wednesday with highs in the low to mid 70s areawide.

220 PM EST Tue Feb 25 2025 Dry high pressure with warm temperatures through midweek.
Satellite and available marine-based surface observations indicate a cold front that pushed through the Florida Keys earlier this morning is now sprawled somewhere over the eastern Straits of Florida.
1206 PM CST Tue Feb 25 2025 Updated aviation portion for 18Z TAF issuance - A mix of light snow, drizzle and freezing drizzle could produce hazardous travel late tonight and Wednesday morning. Even though air temperatures may be a little above freezing in central and east central Wisconsin, drizzle may freeze on the pavement that is cold from the below normal temperatures over the last month.
Dry airmass and slightly warmer temperatures will produce lower RHs this afternoon.
(Through Wednesday) An upper level low is located on the east coast on the Florida peninsula pushing east off into Atlantic. With the region on the backside of the upper level low dry conditions begin to move in through the near term. Although airmass from Pacific is cooler, currently in late february, 2 months after the winter solstice,the solar angle has become high enough to allow for temperatures to increase to the upper 70s midday with clear skies and calm winds.
* Small window for wintry mix before transition to all snow, freezing rain chances lessened, but freeze/refreeze on some roads may be possible.
The low pressure system that was responsible for this winter storm has moved off to the east and out of our area. A ridge is starting to build into the region from the west and is causing surface winds to slow. Despite this, winds will remain above 10 kts into the mid- morning and air temperatures will drop into the lower to mid teens. The ridge will help to clear up the sky a bit today, which will allow temperatures to warm into the upper 40s in the southwestern CWA (locations that received less snow) to the lower 30s in the northeastern CWA (where greater snowpack is).
1241 AM CDT Tue Mar 26 2024 (The rest of tonight) The cold front has moved into NW AR where a narrow line of convection has recently developed. Persistent winds and expanding mid cloud will somewhat limit the temp fall, however overnight temps in the lower to mid 30s are expected for much of the local region. (Tomorrow through Monday) The mid and upper level trof axises are progged to push east of the CWA Tuesday afternoon/evening.
Winds then gradually diminish by midday once the cold front departs. - Sub-freezing temperatures arrive tonight behind the cold front, mainly in areas north of a Taylorville-to-Danville line.
Despite very favorable speed and directional wind shear in the region, overall environment (as assessed with 21Z and 00Z KJAN soundings) is lacking the low- level thermodynamics needed to sustain tornadogenesis this evening.
Upper low will continue to move northeast away from the area early this morning with wrap around flurries/drizzle ending by dawn. Otherwise, a cold northerly wind flow will grip central/eastern Kansas today with low clouds slowest to clear southeast Kansas within the moist low level thermal trof.
1231 AM CDT Tue Mar 26 2024 (Rest of tonight) Showers and a few elevated thunderstorms will continue to spread northeastward across the TN Valley over the next couple of hours, within a rapidly strengthening warm/moist advection regime to the south/east of a mid-level trough lifting northeastward from the MO Valley.
- The Winter Weather Advisory has been expanded to include all of eastern Nebraska and southwest Iowa for a mixture of snow and freezing rain/drizzle Tuesday morning.
135 AM EDT Tue Mar 26 2024 Dry high pressure continues with more seasonable temperatures for Tuesday.
Additionally, improving, but still adverse, seas along the Lower Texas Coast will result in a Moderate Risk of rip currents at the local beaches through the period.

644 AM CDT Tue Mar 26 2024 (Today through Wednesday afternoon) Current surface observations show the weak cold front has nosed into the Permian Basin, bringing light northeasterly winds and a notable chill in the air. Temperatures behind the front have fallen into the 40s and 30s with even below freezing temps at Tatum. The worst of the winds are behind us now that the large upper trough has positioned itself overhead with its base and associated speed max nudged all the way down into Mexico. With this, have extended the High Wind Warning for the Guadalupe zones through 01z. Temperatures this afternoon remain on the cool side due to the lowered thickness with the trough overhead and added cloud cover.
Breezy and milder conditions move in mid- week before another series of weather systems bring cooler temperatures and areas precipitation for the second half of the week. - Fogleman ï»¿Montana remains under a cyclonic northwest flow aloft on the southwest periphery of an upper level trough over central Canada. NW flow pattern favors better chances for repetitive snow showers across the Little/Big Belts, Bridger and Gallatin ranges this afternoon where there is a 50-60% probability of snow accumulation around an inch at Bozeman pass and similar probability for 2 inches over Deep Creek Pass and Kings Hill. Upper level ridging then shifts east across the Rockies Tuesday night and Wednesday for a drier period with temperatures warming back to seasonal levels.
632 AM CDT Tue Mar 26 2024 (Today through Wednesday) An upper level trough covers much of the country with its axis extending over west TX. At the surface, a cold front is stretched across the region from near Giddings to San Marcos to Rocksprings. It will bring some cooler air to the eastern half of the CWA with highs near ten degrees cooler than yesterday. Lows Wednesday will be a few degrees warmer than Tuesday. Wednesday the upper trough axis will move across our CWA and a dryline will move into the area.
Otherwise, drier and warmer into Wednesday but with high temperatures remaining a few to around 5 degrees below average.
A nearly hemispheric length long wave trough covers the western US, while an equally high amplitude upper level ridge reaches north to Quebec. The Western Caribbean holds the core of the mean layer ridge, but may be losing ground to the lower heights spreading into the Gulf of Mexico. The low-level gradient is holding strong this morning across the Keys. Southeast winds at the Reef average 15 to 20 knots, although locations west of the Seven Mile Bridge are a few knots higher. High pressure bulging off the Carolina and Georgia Coasts will maintain fresh east to southeast breezes through early afternoon.
A fast moving upper level ridge will dry things out tonight and Wednesday with the next system quickly allowing Pacific moisture back into Idaho with rain and snow moving back into southeast Idaho. High temperatures again in the 30s mountains to 40s low elevations today with warmer conditions Wednesday as flow aloft turns southwesterly and mainly 40s with some low elevations reaching the low 50s.
(Today and tonight) A broad trough will continue moving across the central US today.
Currently, the low is centered across far northeast Kansas. Some light precipitation (mainly drizzle) continues to wrap-around the backside of the low. Several inches of snow accumulated across isolated portions of far north central Kansas as a deformation band of snow set up and pivoted around basically one point (Republic County) as the low slowly transitioned eastward. Further to the south and east, warmer temperatures and a lack of ice aloft have led to mainly drizzle. Once the sun comes up, ground temperatures should rise quickly above freezing and melt whatever frozen precipitation fell/accumulated. With clear sky and light wind, temperatures are expected to quickly fall well below freezing Wednesday morning.
Light freezing also looks possible in far northwestern Missouri as there remains an elevated layer of air above freezing. Forecast lows Wednesday morning are in the lower to middle 20s.
The only weather impact expected today will be gusty winds with a tight pressure gradient between high pressure east of Florida and a cold front moving through LA/MS. A tight pressure gradient between high pressure east of Florida and a cold front moving through LA/MS will produce gusty southerly winds over the eastern gulf waters through the day.
- Dry and warmer weather is predicted for Wednesday and through the weekend. Some cloud remained across central Kansas where temperatures were slightly warmer due to limited radiational cooling. Meanwhile, an upper level disturbance will approach the high plains by early Wednesday, bringing some mid level cloud to far southwest Kansas. Expect lows in the teens to lower 20s in central Kansas, with warmer lows in the mid 20s farther southwest at Elkhart and Liberal. The aforementioned upper level trough will bring some mid level cloud and possibly a shower or two to southern sections Wednesday.
(Today through Wednesday afternoon) Current surface observations show the weak cold front has nosed into the Permian Basin, bringing light northeasterly winds and a notable chill in the air. Temperatures behind the front have fallen into the 40s and 30s with even below freezing temps at Tatum. The worst of the winds are behind us now that the large upper trough has positioned itself overhead with its base and associated speed max nudged all the way down into Mexico. With this, have extended the High Wind Warning for the Guadalupe zones through 01z. Temperatures this afternoon remain on the cool side due to the lowered thickness with the trough overhead and added cloud cover.
A warmup and dry conditions with gusty winds are expected Wednesday ahead of another low pressure system that will bring cooler temperatures and more rain and snow to the area for the remainder of the week. A mid-level ridge will build over the area tonight into Wednesday bringing dry conditions and a switch in wind direction. The next Pacific low pressure system will follow the short term ridge bringing more rain and snow to northern Nevada late Tuesday night.
646 AM CDT Tue Mar 26 2024 Showers and isolated thunderstorms will move through northeast Mississippi this morning ahead of a cold front which will exit the Mid-South by this afternoon. Cooler and drier air will start to move into the region behind the front.
Breezy and milder conditions move in mid- week before another series of weather systems bring cooler temperatures and areas precipitation for the second half of the week. ï»¿Montana remains under a cyclonic northwest flow aloft on the southwest periphery of an upper level trough over central Canada. NW flow pattern favors better chances for repetitive snow showers across the Little/Big Belts, Bridger and Gallatin ranges this afternoon where there is a 50-60% probability of snow accumulation around an inch at Bozeman pass and similar probability for 2 inches over Deep Creek Pass and Kings Hill. Upper level ridging then shifts east across the Rockies Tuesday night and Wednesday for a drier period with temperatures warming back to seasonal levels.
Winds then gradually diminish by midday once the cold front departs. - Sub-freezing temperatures arrive tonight behind the cold front, mainly in areas north of a Taylorville-to-Danville line. Confidence in areawide sub-freezing temperatures is higher Wednesday night (60% chance or greater).
651 AM EDT Tue Mar 26 2024 Dry high pressure continues with more seasonable temperatures for today.
The actual surface front and cooler air will lag behind the rainfall, and not arrive until this evening in the northwest. If skies clear this afternoon, could see highs in the low to mid 70s across the west. Cooler air arrives tonight as high pressure spreads southeastward through the Plains. Lows will range from the lower 40s northwest to lower 50s southeast.
A cold front will then cross into the area this afternoon from the west in the wake of the exiting rainfall.
610 AM CDT Tue Mar 26 2024 (Today and tonight) A broad trough will continue moving across the central US today.
634 AM CDT Tue Mar 26 2024 (Today through Wednesday) Upper negative tilt trough from Saskatchewan to near Kansas City early this morning. Low pressure over Iowa this morning has a cold front southward that is very close to Interstate 55 at 3 AM CDT. Temperatures were in the lower and middle 70s ahead of the front, but in the 50s well behind the front at 3 AM.
Drier and warmer weather returns the latter half of the week. Longwave trough over much of the country today with the polar jet stream dipping south over northern Mexico. Rain coverage in the lowlands will be quite spotty and with low-end totals but a few isolated thunderstorms may contribute to a quick burst of rain in some areas this evening.
Cooler, but seasonable temperatures return for Wednesday into the weekend.
Behind the boundary, a drier and cooler airmass will prevail. Highs will generally be from the upper 60s (far inland) into the low 70s elsewhere. A quiet and slightly cooler night is expected with lows into the low 40s to low 50s. A broad upper-level trough will make its way to the Plains on Wednesday, increasing vorticity/forcing aloft.
1015 AM EDT Tue Mar 26 2024 Dry high pressure continues with more seasonable temperatures for today.
CUrrent satellite analysis shows a broad H500 trough over the Four Corners Region. This aforementioned trough will move slowly from west to east across the Panhandles later today. High temperatures tomorrow will range from the lower 50s to near 60 degrees with low temperatures tomorrow night from the mid 20s to lower 30s.
The brunt of this cold air advection scenario behind this surface frontal passage later today into tonight will be felt on Wednesday, as high pressure influences out of southern Canada that are diving into the plains push eastward into our area.
Breezy and milder conditions move in mid- week before another series of weather systems bring cooler temperatures and areas precipitation for the second half of the week. ï»¿Montana remains under a cyclonic nrothwest flow aloft on the southwest periphery of an upper level trough over central Canada. NW flow pattern favors better chances for repetitive snow showers across the Little/Big Belts, Bridger and Gallatin ranges this afternoon where there is a 50-60% probability of snow accumulation around an inch at Bozeman pass and similar probability for 2 inches over Deep Creek Pass and Kings Hill.
