Lows will range from the lower 50s over SE GA, to the mid to upper 50s across NE FL. (Tuesday through Wednesday night) High pressure ridging over the area will bring light westerly winds and sunny to mostly sunny skies Tuesday afternoon.
Look for cooler temperatures heading into the weekend.
One is an upper low over NE Mexico and the other is a cold front from the Red River Valley to Kentucky. The upper low will move very slowly NNE and gradually open into a trough by late Wed. The interaction between the upper low and the frontal boundary will help draw and focus some of the moisture over the gulf that should be deep enough to produce some rain in the form of showers at and beyond the coast Wed. Wed will likely be the highest chance of rain through the next several days.
1241 AM CST Tue Feb 4 2025 (Tonight) Upper ridging and warm westerly flow has resulted in above normal temperatures for early February. Overnight lows will range from the upper 40s in the higher terrain of NE AL to mid 50s west of I-65.
(Today through Wednesday) Key Messages: - Patchy dense fog each morning - Unseasonably warm, near record high temperatures for early February A cold front stalls north of our area this afternoon, then lifts back to the north by Wednesday while an upper level low over northeastern Mexico/southern Texas drifts toward the Gulf coast.
1033 PM CST Mon Feb 3 2025 Tomorrow's temperatures are trending cooler with the advent of cold air settling further south.
It has been awhile since we've had a cold front passage. This along with the current wind direction is resulting in above normal conditions with temperatures in the mid 70s and dew points broadly in the lower 70s. Weakening surface ridging will remain draped across the Florida Peninsula through the overnight period.
1111 PM CST Mon Feb 3 2025 (Tonight through Tuesday night) High pressure influence over the eastern Gulf is resulting in southeasterly flow at the surface. There is a weak, meandering closed 500 hPa low in northern Tamaulipas that won't introduce increased PoPs but will continue to, in addition to anti-cyclonic flow around the eastern Gulf high pressure, increase PWATs across the region.
However, land fog has taken longer that anticipated given the low clouds advecting from the south, as showers dissipate.
1057 PM CST Mon Feb 3 2025 - Increasing freezing drizzle chances (peak PoPs of 30-60%) Wednesday. The highest potential for impactful ice accumulation will be in southeast NE into southwest IA.
1002 PM MST Mon Feb 3 2025 - Cooler temperatures persist through the week, with periodic chances for light snow. Tonight into Tuesday morning may see some areas of light freezing drizzle or freezing fog over western SD as soundings show similar thermal profiles compared to last night.
1005 PM MST Mon Feb 3 2025 - Cooler temperatures persist through the week, with periodic chances for light snow. Forecast soundings looking less favorable for freezing drizzle so have removed it from forecast. Tonight into Tuesday morning may see some areas of light freezing drizzle or freezing fog over western SD as soundings show similar thermal profiles compared to last night.
(Tonight) Upper ridging and warm westerly flow has resulted in above normal temperatures for early February. Overnight lows will range from the upper 40s in the higher terrain of NE AL to mid 50s west of I-65.
646 AM EST Tue Feb 4 2025 (Today through Wednesday) The influence of high pressure will remain over the region through the short term forecast period with a warm and humid conditions persisting.
553 AM CST Tue Feb 4 2025 A cold front will cool off portions of the Midsouth north of Interstate 40, while areas in north Mississippi remain in the 70s today.
526 AM CST Tue Feb 4 2025 (Today through Wednesday) Key Messages: - Patchy dense fog each morning - Unseasonably warm, near record high temperatures for early February A cold front stalls north of our area this afternoon, then lifts back to the north by Wednesday while an upper level low over northeastern Mexico/southern Texas drifts toward the Gulf coast.
(Today and tonight) A cold frontal boundary will make it's way into the Big Country and Concho Valley today. This will result in much cooler conditions across the region. Some cloud cover may also make it's way south with the cold frontal boundary. Elsewhere, the highs will be in the upper 70s.
317 AM MST Tue Feb 4 2025 - Wide range of temperatures today, with most of the state seeing a surge of warmer south winds. - Warmer temperatures push farther north on Wednesday, before a cold front pushes across the state late Wednesday afternoon. Conditions will be generally quieter across the state today, as a warm front tries to surge northward across the state. Areas from Rock Springs to Casper will reach the low to mid 50s. A little remaining moisture pushing into the western mountains may bring a brief rain/snow mix for the higher elevations today, but any further accumulations will be minimal.
Updated at 327 AM CST Tue Feb 4 2025 - Much cooler today, with drizzle/light rain chances increasing this afternoon and evening.
Highs for today and Wednesday will continue to reach into the upper 70s to low 80s inland and into the low 70s along the coast.
- Warmer-than-average conditions continue. Subtle 500 mb troughing and an attendant cold front are noted from the Northeast to the OH/TN River Valley. High temperatures are forecast to range from the lower 70s to around 80, which is 15-22 degrees above average. Quasi-zonal flow to weak ridging is expected across the eastern CONUS on Wednesday.
- Freezing drizzle is possible (15-30%) Wednesday morning for areas primarily east of highway 281.
From our live 12z sounding, there is some drier air at the lower levels, the snow will have to overcome this. This morning will have the lowest wind chill values with that cold high pressure causing light winds. The incoming low pressure is creating widespread snow in Montana right now, although not sure what is making it to the ground. After 3am CT, a snow band is forecast to Be Legendary and move through the western half of North Dakota, limited by the high pressure center to the north and east.
Temperatures are hovering in the lower to mid 70s, with sticky dewpoints in the lower 70s, and winds on land from the northeast to east at 5 to 10 mph. Surface analysis depicts high pressure over the SW Atlantic and extending westward across the Florida peninsula into the northern Gulf. Aloft, deep ridging continues to dominate our region. We expect little change through the entire forecast period, as deep ridging aloft remains dominant with passing cold fronts diverted well north of our area.
The overall pattern will not change much over the next couple of days with ridging remaining in place over the southern Gulf. The upper low over the southwestern gulf will remain stuck there for the foreseeable future waiting for its turn to merge back into the main flow.
418 AM PST Tue Feb 4 2025 A low pressure system to the north will direct moisture from a weakening atmospheric river into California this week with the most significant rainfall expected from Los Angeles County northward.
239 AM MST Tue Feb 4 2025 The unseasonably strong high pressure impacting the region will again result in near record highs today of around 85 degrees. A very warm air mass has developed across our region over the past couple of days with the help of a near climatological record strength upper level ridge centered over northern Mexico. Yesterday's highs across the lower deserts topped out in the low to mid 80s with Phoenix tying the daily record high of 86 degrees, despite some thin high cirrus. For today, the influence of the ridge will begin to wain a bit as a large Pacific trough centered off the coast of Washington nudges the ridge farther to the southeast.
An additional 5 to 12 inches of snow is likely from 12z this morning until 12z Wednesday from Ketchum to Stanley with up to a foot on the upper slopes and ridges. Temps are too warm to support significant snow in the lower valleys. Temperatures look warm again today with areas around Pocatello approaching 50 and areas around Burley in the low to mid 50s. On Wednesday, a cold front will sweep through the region. Some of the upper slopes and ridges could see up to 6 inches. The probability of exceeding wind advisory gusts in the upper Snake Plain is around 55% but drop off to around 15 to 20 percent for the lower Snake Plain and Magic Valley. Temps on Wednesday are cooler but not significantly so.
Cold wintry weather continues as warmer moist air moves on. Eel river at Fernbridge has gaged higher than what was originally forecasted and is still rising (23. The Eel at Fernbridge is forecasted to drop below Moderate (22ft) flood stage around 4pm today. The next biggest concern will be potential for light convective activity along the northern Humboldt and Del Norte coasts Wednesday as freezing levels plunge across the CWA with the arrival of a cold core upper low.
427 AM MST Tue Feb 4 2025 - Wide range of temperatures today, with most of the state seeing a surge of warmer south winds. - Warmer temperatures push farther north on Wednesday, before a cold front pushes across the state late Wednesday afternoon. Conditions will be generally quieter across the state today, as a warm front tries to surge northward across the state. Areas from Rock Springs to Casper will reach the low to mid 50s. A little remaining moisture pushing into the western mountains may bring a brief rain/snow mix for the higher elevations today, but any further accumulations will be minimal.
After that, zonal flow aloft transitions to more northwesterly through the day as the axis of a ridge builds to our west. Highs may be in the low to mid 50s in the northern portion of the FA while temperatures in the CSRA may break into the 70s. Much of the temperature forecast will depend on the southernmost extent of the cold air wedge boundary and any possible erosion of the low clouds on the southern end.
533 AM CST Tue Feb 4 2025 Updated at 531 AM CST Tue Feb 4 2025 - Much cooler today, with drizzle/light rain chances increasing this afternoon and evening.
518 AM CST Tue Feb 4 2025 - Freezing drizzle could lead to slick roads Wednesday morning into early Wednesday evening (40-60% chance). The highest potential for travel impacts will be in southeast NE into southwest IA.
(Today and tonight) A cold frontal boundary will make it's way into the Big Country and Concho Valley today. This will result in much cooler conditions across the region. Additionally, some cloud cover may also make it's way south with the cold frontal boundary. Elsewhere, the highs will be in the upper 70s.
518 AM CST Tue Feb 4 2025 Updated at 506 AM CST Tue Feb 4 2025 - Cold front brings slightly cooler temperatures to the Permian Basin today with record highs expected again out west.
A cold front will cool off portions of the Midsouth north of Interstate 40, while areas in north Mississippi remain in the 70s today.
331 AM CST Tue Feb 4 2025 - Freezing drizzle could lead to slick roads Wednesday morning into early Wednesday evening (40-60% chance). The highest potential for travel impacts will be in southeast NE into southwest IA.
1125 AM CST Tue Feb 4 2025 (Today through Wednesday) Key Messages: - Patchy dense fog each morning - Unseasonably warm, near record high temperatures for early February A cold front stalls north of our area this afternoon, then lifts back to the north by Wednesday while an upper level low over northeastern Mexico/southern Texas drifts toward the Gulf coast.
Southwest flow aloft will remain over the desert southwest as a Pacific Northwest trough sits to the north. While the broad ridge that has brought unseasonably warm temperatures continues to shift east, the region remains under strong positive mid- upper level height anomalies.
- Patchy light freezing drizzle possible southeast of Dodge City Wednesday morning.
239 PM EST Tue Feb 4 2025 - Freezing rain is expected Wednesday night, but some uncertainty remains with duration and accretion amounts.
349 PM EST Tue Feb 4 2025 High pressure will provide dry conditions tonight into Wednesday. Low pressure will approach the Ohio Valley Wednesday night, bringing precipitation to the region.
1133 AM CST Tue Feb 4 2025 A cold front will cool off portions of the Midsouth north of Interstate 40, while areas in north Mississippi remain in the 70s today.
Highs will reach the mid 80s across southwest FL, while the moderating influence of the light sea breeze will help keep temperatures along the East Coast in the low 80s.
From synopsis, gentle to moderate easterly breezes will persist across the Florida Keys coastal waters through the rest of this week, as several areas of high pressure move across the eastern United States and into the western North Atlantic.
1005 AM MST Tue Feb 4 2025 Updated Aviation Unseasonably strong high pressure will continue to impact the region today resulting in near record high temperatures. A very warm air mass has developed across our region over the past couple of days with the help of a near climatological record strength upper level ridge centered over northern Mexico. The influence of this ridge will begin to wane a bit as a large Pacific trough centered off the coast of Washington nudges the ridge farther to the southeast.
pdf Warmer than seasonable temps continue this afternoon with mostly clear skies, while high pressure dominates the region at the surface and aloft. The mean ridge aloft around 500 mb is located over the Gulf and will shift slightly eastward through tonight. Meanwhile, at the surface, high pressure centered south of the FL panhandle in the Gulf will shift to be over north central FL by sunrise on Wednesday.
259 PM EST Tue Feb 4 2025 High pressure builds in tonight through Wednesday along with the arrival of a colder airmass.
Updated at 145 PM CST Tue Feb 4 2025 - Freezing drizzle possible across northern Oklahoma tonight. Temperatures have actually been steady and/or slowly rising across most locations this afternoon--shifting the freezing line back to the northwest. Temperatures across northwest into north central Oklahoma are most likely to be at or below freezing. Therefore, there area has the potential for freezing drizzle.
1000 AM MST Tue Feb 4 2025 - Wide range of temperatures today, with most of the state seeing a surge of warmer south winds. - Warmer temperatures push farther north on Wednesday, before a cold front pushes across the state late Wednesday afternoon. Conditions will be generally quieter across the state today, as a warm front tries to surge northward across the state. Areas from Rock Springs to Casper will reach the low to mid 50s. A little remaining moisture pushing into the western mountains may bring a brief rain/snow mix for the higher elevations today, but any further accumulations will be minimal.
Considering the min temperatures in lower 60s this morning and again tonight, temperatures today are about 15 to 25 degrees warmer than normal for early February. Model consensus from both the GFS and the NAM still supports quasi-zonal flow that will continue across much of the CONUS with a subtropical ridge centered over the Bahamas/Cuba.
1104 AM CST Tue Feb 4 2025 Updated at 1101 AM CST Tue Feb 4 2025 - Cold front brings slightly cooler temperatures to the Permian Basin today with record highs expected again out west.
1134 AM CST Tue Feb 4 2025 Updated at 1035 AM CST Tue Feb 4 2025 - Much cooler today, with areas of drizzle and also light rain chances.
300 PM CST Tue Feb 4 2025 - Light snow and freezing drizzle are possible overnight into early Wednesday morning across the Sandhills and northern Nebraska.
* Much cooler today with a cloudy start and partial clearing this afternoon.
1100 AM EST Tue Feb 4 2025 Post frontal fog and drizzle this morning will give way to high pressure building into the region.
243 PM CST Tue Feb 4 2025 - High confidence (>90%) om freezing drizzle for much of central and southern Iowa on Wednesday. Possibly light snow or freezing drizzle north.
300 PM EST Tue Feb 4 2025 High pressure builds in tonight through Wednesday along with the arrival of a colder airmass.
(This evening through Wednesday) A cold front has moved south into the southern Concho Valley, roughly along a line from Mertzon to Christoval, east to near San Saba. North of the front, temperatures ranged from the lower 50s to mid 60s, while to the south, temperatures were in the mid 70s to lower 80s. This front will lift back to the north as a warm front tonight into tomorrow morning. Highs will range from the low to mid 70s in southern areas that will be contending with cloud cover into the afternoon hours, to near 80 degrees in the Big Country where mostly sunny skies will allow for more warming.
Updated at 1035 AM CST Tue Feb 4 2025 - Much cooler today, with areas of drizzle and also light rain chances.
For the rest of the week, similar patterns are expected with high pressures continuing to dominate our area.
117 PM PST Tue Feb 4 2025 A low pressure system to the north will direct moisture from an atmospheric river into California this week, with the most significant rainfall expected from Los Angeles County northward.
241 PM MST Tue Feb 4 2025 - Warmer temperatures for Wednesday, however uncertainty remains on the spread of temperatures across the region.
- Freezing drizzle is possible tomorrow morning and afternoon, primarily for portions of northern Missouri. With the cloud cover and some very modest theta e advection, temperatures overnight are not expected to drop much, with overnight lows ranging from the mid 20s to the lower 30s. Freezing drizzle will be possible across portions of northern Missouri, with up to one tenth of an inch of ice accumulation possible. As far as the KC Metro is concerned, the NAM NEST continues to suggest the potential for freezing drizzle early tomorrow morning, but its low level moisture seems too high to be realistic, and with only modest lift, seems more likely to result in stratus rather than freezing drizzle. At this time, no other model is suggesting a freezing drizzle threat for KC tomorrow morning.
- High confidence (>90%) om freezing drizzle for much of central and southern Iowa on Wednesday. Possibly light snow or freezing drizzle north.
525 PM CST Tue Feb 4 2025 (Tonight through Wednesday night) Key Messages: -Unseasonably warm and humid for early February -Clouds a bit more stubborn during the day on Wednesday A cold front is pushing southward today across the state but is forecast to stall into this evening towards our CWA boundary with the San Angelo and Fort Worth CWAs.
Drizzle, freezing drizzle, and fog are possible in the southeastern Panhandles tonight, while also extending up to the eastern Oklahoma Panhandle.
523 PM CST Tue Feb 4 2025 Updated at 519 PM CST Tue Feb 4 2025 - Freezing drizzle possible across northern Oklahoma tonight. Temperatures have actually been steady and/or slowly rising across most locations this afternoon--shifting the freezing line back to the northwest. Temperatures across northwest into north central Oklahoma are most likely to be at or below freezing. Therefore, there area has the potential for freezing drizzle.
303 PM CST Tue Feb 4 2025 - There remains a very small chance for some light freezing drizzle Wednesday morning (~10%) for areas primarily east of highway 281.
- Warmer-than-average conditions continue. At the surface, we are expecting a weak high pressure ridge/wedge to build into NE GA which will help to keep things fairly stable over the area.
550 PM EST Tue Feb 4 2025 - Freezing rain is expected Wednesday night, but some uncertainty remains with duration and accretion amounts.
639 PM EST Tue Feb 4 2025 High pressure will provide dry conditions tonight into Wednesday. Low pressure will approach the Ohio Valley Wednesday night, bringing precipitation to the region.
A cold front expected to move through the state tonight, bringing in cooler temperatures and increasing chances for rain and snow showers. This is due to a closed low pressure system that has not moved much over the Pacific Northwest. For tonight, a cold front is expected to cross into Humboldt county, slowly working its way eastward through the early morning hours into the afternoon. Precipitation is expected to remain mostly rain showers in the valleys, though some of the higher valleys above 6000 feet could see up to a half inch. Highs tomorrow will be much cooler with readings in the 40s and 50s.
359 PM CST Tue Feb 4 2025 - Freezing drizzle is possible tomorrow morning and afternoon, primarily for portions of northern Missouri.

Much cooler air has filtered into the area behind a strong cold front, which now resides across portions central and north TX. At this hour temperatures range from the low 20s across central KS to the upper 30s across southeast KS. This has resulted in occasional light drizzle and freezing drizzle. As a stronger midlevel trough ejects into the Plains late tonight into Wednesday, stronger low-level WAA will overspread the area. At this point, areas along and northwest of the KS Turnpike stand the greatest potential for receiving ice accumulation with freezing drizzle. Regardless if a Winter Weather Advisory is issued, at least patchy slick spots are probable, especially on elevated surfaces (bridges and overpasses). By Wednesday afternoon, considerable uncertainty remains with the placement of a warm front and associated temperatures.
(This evening through Wednesday night) A relatively flat upper level flow pattern that has been in place is transitioning to increasing heights as a trough begins to dip into the northeastern CONUS and upper ridging develops along an axis right on the eastern side of the Rocky Mountains.
