By this afternoon, temperature maximums will reach the low-to-mid 70s and continue to be much warmer than normal for this time of the year. Temperatures today to climb into the low to mid 70s with overnight lows in the low to mid 50s. Dewpoints in the upper 40s today are forecast to climb into the lower 60s by Monday.
1012 AM EST Sun Feb 2 2025 High pressure will shift offshore early this week bringing warmer temperatures.
240 PM EST Sun Feb 2 2025 High pressure extending down the East Coast will give way to a lee trough on Monday ahead of a cold front approaching from the northwest.
Monday will be pretty similar to today, just warmer and likely more sunshine starting at daybreak; highs will be in the 65 to 70 range across most of the TN Valley.
114 PM EST Sun Feb 2 2025 Southerly flow will bring very warm temperatures until a cold front moves through late Monday into Monday night.
Water vapor shows upper trof over the Pac NW with broad moist zonal flow extending eastward through the Northern Plains. A mixed bag of precipitation is lifting northeast across the area given temps near or a bit above freezing atop the shallow colder air mass. Mostly snow will fall in the northern zones, with a mixed bag of snow/rain/freezing rain further south given warmer air aloft. Fog/freezing fog will likely remain an issue at least through the evening on the northern/eastern slopes of the Black Hills given the moist upslope flow. A cold front will stall near the SD/NE border today. An arctic cold front will slide into the area tonight with better chances for snow, especially north of Interstate 90. A bit of freezing rain may occur ahead of the arctic front this evening.
Snow, rain, and freezing rain are all possible. DDV Issued 430 AM CST Sun Feb 2 2025 Today through Monday: Light snow has ended, but low clouds and drizzle / freezing drizzle are expected to continue early this morning, tapering off from west to east around 8 AM. Modest southeast winds will decelerate and veer southwest over the next few hours, with daytime highs in the low to mid 40s expected this afternoon.
In the lower elevations, temperatures are warm enough again this afternoon to support rain and we've seen light to moderate rainfall for much of the day.
916 AM MST Sun Feb 2 2025 - Cold front arrives today with much colder air surging into the region late tonight into Monday. Public reports and webcams show some freezing drizzle across the northern Black Hills/foothills area, so have added this to the forecast as well as issue an SPS until 18Z. A surface cold front is analyzed from eastern ND along the ND/SD border and arching back into southern MT. The cold front will settle southward through the day today.
1131 AM CST Sun Feb 2 2025 - Well above normal temperatures, as highs warm well into the 60s today then the lower 70s Monday.
The higher dewpoints and elevated winds will keep temperatures even warmer tonight, with the forecast lows tomorrow morning in the mid 40s to mid 50s. Tomorrow, continued upper ridging and south/southwest winds will bring another day of above normal and potentially record breaking temperatures.
(This afternoon through Monday) Light southeasterly to easterly wind flow as high pressure builds back over the region. A warmer Sunday with dewpoints in the 70s and the retreat of the weakening front's cloud shield has allowed for more convective cloud coverage which will open the door for some showers this afternoon and evening.
1129 AM CST Sun Feb 2 2025 Southerly winds on the back side of high pressure will bring milder temperatures to the Mid-South this week.
(Tonight) High pressure remains layered from the NE Atlantic states into the SE region this Sun afternoon. Seasonably warm/tranquil conditions also prevail across the mid TN Valley, with current temps mainly in the lower/mid 60s. Other than some mid/high clouds out of the NW filtering into the area tonight, quiet wx conditions look to continue into early Mon, as lows fall predom into the lower/mid 40s for most spots.
It's a sunny and mild day around northern Arizona, with well above normal temperatures and breezy southwest winds over the high country. Troughing will continue near the Pac NW through mid week before sliding inland by late week.
230 PM EST Sun Feb 2 2025 (This afternoon through Monday) Key Messages: - Dry and warmer than-average conditions will continue. Main high pressure ridge over the area strengthen a bit tonight as it becomes centered over GA/SC by Mon morning. This ridge slides slowly South becoming centered over central FL Tue. This ridge will keep things dry through the short term but we will begin to see a little moisture return Mon night into Tue. With this ridge right over the area winds will be fairly calm tonight.
(This afternoon through Monday night) A mid-level ridge is currently building its way into the region today. This ridge, along with a strengthening low-level thermal ridge will bring in a very warm, continuous dry weather pattern heading into the upcoming week. Tomorrow morning low temperatures are expected to be mild ranging from the lower 40s to lower 50s, while highs generally reach the 80s regionwide tomorrow afternoon.

257 PM CST Sun Feb 2 2025 - After a mild one today, cooler air coming to the area Monday.
1050 AM MST Sun Feb 2 2025 - Cold front arrives today with much colder air surging into the region late tonight into Monday. Public reports and webcams show some freezing drizzle across the northern Black Hills/foothills area, so have added this to the forecast as well as issue an SPS until 18Z. A surface cold front is analyzed from eastern ND along the ND/SD border and arching back into southern MT. The cold front will settle southward through the day today.
This is due to sustained southerly onshore flow that picks up on the backside of the ridge axis parked over the southeast U.
Temperatures will continue to warm over the next few days as high pressure continue to build over the region.
1030 AM MST Sun Feb 2 2025 - Snow will continue to fall over the northern Colorado mountains today but with mild conditions moving in impacts will be limited to the highest terrain of the Park Range.
By this afternoon, temperature maximums will reach the low-to-mid 70s and continue to be much warmer than normal for this time of the year.
This will support freezing drizzle and fog on the plains adjacent to the Black Hills with a light glaze to a few hundredths of an inch of ice possible. Water vapor shows upper trof over the Pac NW with broad moist zonal flow extending eastward through the Northern Plains. A mixed bag of precipitation is lifting northeast across the area given temps near or a bit above freezing atop the shallow colder air mass. Mostly snow will fall in the northern zones, with a mixed bag of snow/rain/freezing rain further south given warmer air aloft. Fog/freezing fog will likely remain an issue at least through the evening on the northern/eastern slopes of the Black Hills given the moist upslope flow. As a cold front slowly slides through the region tonight, a mix of fog, snow, and freezing drizzle is expected.
The cloud cover may further impact high temperatures on Monday as a cold front moves across the area through the day. Currently less cloud cover is forecast south of a Fairfield to Galesburg line where the warmest temperatures are forecast ahead of the cold front, A wide range of temperatures is possible with the current forecast showing a range from the lower 40s along the Highway 20 corridor to the upper 50s in far southeast Iowa, far northeast Missouri and west central Illinois.
344 PM CST Sun Feb 2 2025 - Warmer conditions are leading to ice breakup on parts of the Platte and Elkhorn Rivers. Ice jam development remains possible (less than 30% chance) with warmer temperatures sticking around through Monday. - Expect a return to cooler, seasonal temperatures beyond Monday, with highs mostly in the 30s to lower 40s.
A few upper 40s are noted in far NE AL this evening, but otherwise, with high pressure anchored over the Big Bend of FL, calm conditions are expected overnight. Morning lows to start the new work week ahead will remain mild, only bottoming out in the lower/middle 40s tonight.

627 PM EST Sun Feb 2 2025 Southerly flow will bring very warm temperatures until a cold front moves through late Monday into Monday night. Even after the frontal passage, temperatures will remain above normal with the next area of low pressure moving into the region midweek. Southerly flow will increase during the day as low pressure tracks across the Great Lakes and a cold front approaches. Moisture will remain in the low levels but there could enough lift to produce a bit of very light rain or drizzle.
627 PM EST Sun Feb 2 2025 A brief period of cooler temperatures continues this afternoon, before warming begins tomorrow and continues throughout most of the week.
- After a very mild Sunday, cooler air arrives to the area Monday.
621 PM EST Sun Feb 2 2025 (This afternoon through Monday) Light southeasterly to easterly wind flow as high pressure builds back over the region. A warmer Sunday with dewpoints in the 70s and the retreat of the weakening front's cloud shield has allowed for more convective cloud coverage which will open the door for some showers this afternoon and evening.
950 PM EST Sun Feb 2 2025 Southerly flow will bring very warm temperatures until a cold front moves through late Monday into Monday night. Even after the frontal passage, temperatures will remain above normal with the next area of low pressure moving into the region midweek. Cooler temperatures in our northern counties are resulting in lower dewpoint depressions, leading to some patchy fog development already this evening. Southerly flow will increase during the day as low pressure tracks across the Great Lakes and a cold front approaches. Moisture will remain in the low levels but there could enough lift to produce a bit of very light rain or drizzle.
High pressure will remain over the waters keeping winds generally 10 knots or less out of the north and east, except shifting to onshore with the sea breeze each afternoon. The colder waters combined with warmer air temperatures and higher humidity could lead to some sea fog each night into the morning hours. Strong ridging overhead along with zonal flow across much of the United Stated will keep temperatures very warm for next work week. Ridging over the area will keep warm and moist air over the state for all of next work week.
624 PM EST Sun Feb 2 2025 (Through Monday) Surface ridging will be in place emanating from high pressure in the Carolinas which will gradually shift offshore Monday. Patchy dense fog could also develop, which the highest probs favor east of Albany and Tallahassee.
Lows tonight will be mild (3-8 degrees above normal) and range from the low 40s interior communities to around 50 degrees at the beaches.
231 PM MST Sun Feb 2 2025 KEY MESSAGES: - A slow moving upper trough in southern Canada will keep Arctic air in place through the end of the week.
746 PM EST Sun Feb 2 2025 High pressure will shift offshore early this week bringing warmer temperatures.

As a cold front slowly slides through the region tonight, a mix of fog, snow, and freezing drizzle is expected.
The hottest days will be Monday and Tuesday, with lower desert high temperatures in the low to mid eighties. Noon temperatures around the region were running around 5-10 degrees warmer than noon temperatures yesterday. Unseasonably strong high pressure over the region and clear skies are driving the warmer temperatures. This will translate to lower desert high temperatures in the low to mid 80s.
129 AM EST Mon Feb 3 2025 Southerly flow will bring very warm temperatures until a cold front moves through late Monday into Monday night. Even after the frontal passage, temperatures will remain above normal with the next area of low pressure moving into the region midweek. Cooler temperatures in our northern counties are resulting in lower dewpoint depressions, leading to some patchy fog development already this evening. Southerly flow will increase during the day as low pressure tracks across the Great Lakes and a cold front approaches. Moisture will remain in the low levels but there could enough lift to produce a bit of very light rain or drizzle.
Surface ridging stretching from the southeastern United States to the adjacent Atlantic Ocean is resulting in gentle largely easterly breezes across the Keys this evening. Temperatures are still in the mid 70s with dew points in the lower 70s. Deep layered ridging is in place and this evenings sounding indicated strong inhibition based around 800 mb with considerable dry air above. Expect overnight lows to be in the lower 70s, not far from the dew point. High pressure aligned over the southeastern United States and adjacent Atlantic Ocean will maintain gentle to moderate mostly easterly breezes on Keys waters through the overnight period.
1146 PM CST Sun Feb 2 2025 (Tonight through Tuesday night) High pressure has shifted to the Atlantic coast this afternoon and it extends back into the north central gulf coast.
It's a sunny and mild day around northern Arizona,Mwith well above normal temperatures and breezy southwest winds over the high country. Troughing will continue near the Pac NW through mid week before sliding inland by late week. As the low moves inland later in the week, a few of the model ensemble members bring the trough and moisture far enough south for a light shower in northwest Arizona.
An impressive upper level trough remains off the Pacific NW coast this afternoon. Temperatures reach the low to mid 50s near Twin Falls this afternoon and Monday afternoon.
A few areas across far southwestern Kansas may reach 80 degrees - A cold front moving through by this evening will usher in seasonably colder air tomorrow An unseasonably warm airmass will be in place today with west to northwest downslope winds and mostly clear skies. The exception to this will be across our northeast zones where a backdoor cold front will move through early enough for only 60s to be observed for highs. This cold front will sweep through the remainder of the forecast area this evening shifting winds to the east to northeast.
(Today through Tuesday afternoon) Mid level ridging continues to expand across TX today along with strengthening downslope flow at the surface. Subtle changes occur Tuesday with winds remaining more southerly across the Permian Basin helping to keep temperatures slightly cooler due to the extra moisture.
(This afternoon through Monday night) A mid-level ridge is currently building its way into the region today. This ridge, along with a strengthening low-level thermal ridge will bring in a very warm, continuous dry weather pattern heading into the upcoming week. Tomorrow morning low temperatures are expected to be mild ranging from the lower 40s to lower 50s, while highs generally reach the 80s regionwide tomorrow afternoon. Similar Tuesday morning lows are anticipated being just a touch warmer compared to Monday morning lows.
Broad ridging aloft continues to sit over the desert southwest. Impressive positive height and temperature anomalies are associated with this ridge via NAEFS climatology guidance, with 700mb temperatures exceeding the ceiling of the data set.
Otherwise, high pressure will be offshore today with strengthening ridging over the central US. While winds at the surface will be mostly light, they will increase out of the southwest between 5 to 10 mph with high pressure offshore leading to warm advection. Tonight, a cold front will approach the forecast area from the northwest with a strengthening low level jet and surface winds.
Typically, the NBM seems to under perform in the shallow cold air and we continue to trend cooler in the Tue-Wed periods. We continue to see considerable uncertainty with respect to low level saturation and the low level thermal profile but some low pops were maintained.
1051 PM CST Sun Feb 2 2025 Overnight low temperatures tonight have been bumped up a few degrees to account for the high cloud cover across most of the region. This is due to sustained southerly onshore flow that picks up on the backside of the ridge axis parked over the southeast U.
-A backdoor cold front could keep the northeast half of the Panhandles in low clouds on Tuesday and create a large temperature gradient across the region.
Roads may take a while to become slick due to antecedent rain and road temps above freezing, but continuous snow and temps at or near freezing will eventually allow roads to become snow-covered and slick. An impressive upper level trough remains off the Pacific NW coast this afternoon. Temperatures reach the low to mid 50s near Twin Falls this afternoon and Monday afternoon.
An upper level low over northeastern Mexico and deep south Texas should remain far enough south for little or no impacts to our area.
It's a sunny and mild day around northern Arizona, with well above normal temperatures and breezy southwest winds over the high country. Troughing will continue near the Pac NW through mid week before sliding inland by late week. As the low moves inland later in the week, a few of the model ensemble members bring the trough and moisture far enough south for a light shower in northwest Arizona.
(Tonight through Tuesday night) Key Messages: - Patchy to areas of dense fog this morning and again Tuesday morning High pressure will continue our southeasterly flow today through Tuesday, streaming moisture and warm air into the area.
1232 AM EST Mon Feb 3 2025 (This afternoon through Monday) Light southeasterly to easterly wind flow as high pressure builds back over the region.
With zonal flow aloft, there is no significant synoptic-scale forcing to advance the cold front southward. Instead, the cold front will move southward primarily due to a density gradient since colder air is relatively denser. Temperatures near the Kansas/Oklahoma border will have to be monitored carefully as there could be the potential for freezing drizzle.
A few upper 40s are noted in far NE AL this evening, but otherwise, with high pressure anchored over the Big Bend of FL, calm conditions are expected overnight. Morning lows to start the new work week ahead will remain mild, only bottoming out in the lower/middle 40s tonight. Low-level flow out of the SW/W should again translate into seasonably warm temps Mon/Tue, as highs both days climb into the lower 70s/near 70F, while lows Mon night trend in the lower 50s/near 50F.
959 PM CST Sun Feb 2 2025 Overnight low temperatures tonight have been bumped up a few degrees to account for the high cloud cover across most of the region. This is due to sustained southerly onshore flow that picks up on the backside of the ridge axis parked over the southeast U.
A deep layer ridge will continue to build over the area, and this will keep rain chances suppressed due to subsidence and dry air aloft remaining in place.
(Today through Tuesday) Light southeasterly to easterly wind flow will continue through the short term period as high pressure builds back over the region. A warmer beginning of the week is expected with dewpoints in the mid-upper 60s and high temperatures in the low to mid 80s. Temperatures will remain slightly cooler near the immediate coasts due to sea breeze development.
This will support freezing drizzle and fog on the plains adjacent to the Black Hills with a light glaze to a few hundredths of an inch of ice possible. Water vapor shows upper trof over the Pac NW with broad moist zonal flow extending eastward through the Northern Plains. A mixed bag of precipitation is lifting northeast across the area given temps near or a bit above freezing atop the shallow colder air mass. Mostly snow will fall in the northern zones, with a mixed bag of snow/rain/freezing rain further south given warmer air aloft. Fog/freezing fog will likely remain an issue at least through the evening on the northern/eastern slopes of the Black Hills given the moist upslope flow. As a cold front slowly slides through the region tonight, a mix of fog, snow, and freezing drizzle will continue.
By tonight, a weak trough is over the Northeast and a ridge is building into the Southeast. At the surface, high pressure is over the Southeast today and low pressure is over the Northeast. A weak cold front will slowly move through the Ohio Valley tonight.
Attendant cold front currently draped across the central U. Expansive high pressure looks to build from south-central Canada and the northern Great Plains toward the Great Lakes tonight. Forecast soundings show the lowest ~700mb of the profile around -5 C, which will promote some smaller flake sizes and relatively wet snowfall. Lesser amounts are expected across the far southern CWA and near the immediate lakeshores where rain may mix in with snow at times as temperatures hover close to/just above freezing into this afternoon.
Ridge axis aloft sits over the S FL peninsula/FL Straits this morning, while at the surface weak high pressure ridges into the state from the W Atlantic replacing the lingering frontal boundary that washed out over the area over the past 24 hours.

315 AM MST Mon Feb 3 2025 KEY MESSAGES: - A slow moving upper trough in southern Canada will keep Arctic air in place through the end of the week.
929 AM EST Mon Feb 3 2025 Warm and breezy conditions will be in place for today before a cold front moves through tonight. High pressure and dry conditions will be in place for Tuesday.
Moisture associated with a 500mb low over northeast Mexico will continue streaming northward over Deep South Texas and the Lower Texas Coastal waters through Tuesday. Highs today and Tuesday are expected to range from the 70s at the beaches to the low to mid 80s inland under a mix of sun and clouds.
610 AM CST Mon Feb 3 2025 (Today through Tuesday Night) The near term will begin with low level moisture increasing ahead of a cold front approaching from the Plains. North of the front, temperatures will be cooler than today, and may be lower than what is indicated in the going forecast. This will happen as a large area of high pressure advances from the upper Midwest to the Ohio Valley and the mid-Atlantic states.
* A strong cold front will move through the region today.
357 AM CST Mon Feb 3 2025 * A strong cold front will move through the region today.
