1158 PM CST Fri Jan 24 2025 - Cold front passes through the area tonight with gusty winds and snow showers producing reduced visibility.
1140 PM CST Fri Jan 24 2025 - Cloudy and cooler for the weekend. - Warmer for early and mid week. With high pressure centered off to our east, southerly winds are leading to decent warm air advection across the region. leaving the center of the country under a building ridge.
1030 PM CST Fri Jan 24 2025 (Rest of Tonight) The satellite is clear tonight across AL with light/variable to near calm winds and surface ridging present. A few cumulus clouds will persist through the afternoon generally east of I-65 as the trough axis is now moving into Central Alabama from the west. Otherwise, we'll have to get through another cold night tonight as high pressure moves into the area with very dry air remaining in the region. Lows will be in the upper 10s to the low 20s into tomorrow morning thanks to efficient radiational cooling. The high pressure center will shift to our east by tomorrow afternoon allowing for a more evident warm-up thanks to a light southerly breeze.
225 AM EST Sat Jan 25 2025 High pressure will hold over the Southeast coast over the weekend.
At the surface, cold and very dry high pressure will prevail. Temperatures tonight into Saturday morning will be below freezing for a total of up to 10-15 hours. But keeping in mind that should it occur, with temperatures as cold as they are, this would be defined as freezing fog. Highs on Saturday should reach the low 50s.
1259 AM EST Sat Jan 25 2025 High pressure will weaken as the air mass gradually modifies through the weekend.
1248 AM EST Sat Jan 25 2025 High pressure builds overhead through Saturday.
1239 AM EST Sat Jan 25 2025 High pressure will build east of the area overnight.
Cold front in association with this system drops through the area late day but until then swrly low level flow/mixing expect temps to crack freezing this aftn. Briefly colder tomorrow as plains centered ridge builds in.

Current synoptic set-up of relevance is a developing closed low over northern California.
1112 PM CST Fri Jan 24 2025 - Potential for light snow across western Nebraska this evening through tonight mainly from Hwy 61 westward and especially from the western sandhills toward the Pine Ridge.
Satellite and radar imagery are picking up a shallow cold front that's slowly advancing westward through Idaho.
326 AM EST Sat Jan 25 2025 High pressure over the eastern United States will retreat southward and weaken through tonight while a cold front approaches from the west.
First, the low clouds that have plagued our skies over the past couple of days have finally slid east clearing the skies above the Lower Keys. The clouds are expected to continue following the tail end of a cold front analyzed east of the Bahamas eventually clearing the rest of the island chain overnight. High pressure building along the Gulf coast will continue to fuel fresh to strong winds in our coastal waters. Tomorrow morning's lows will be in the lower 50s across the Lower and Middle Keys, with portions of the Upper Keys possibly sliding into the upper 40s due to CAA. Breezes are expected to slacken tomorrow as the high pressure builds east. From synopsis, breezes will sharply freshen overnight with strong breezes expected into Saturday, as high pressure builds over the Gulf Coast.
High pressure over Georgia and the Carolinas today will send warming southwest winds into the Mississippi and Ohio Valleys.
1225 AM EST Sat Jan 25 2025 High pressure will hold over the Southeast coast over the weekend.
Several consecutive days of temps above freezing should melt remaining snow across the area.
Today: Cold front continues to move across the region this morning, with temperatures in lower teens in the Devils Lake Basin and in the lower 20s in the southern Red River Valley.
Slightly less wind Sunday and a bit cooler. An upper low will close off near San Francisco this afternoon and then wobble down the coastline for the next 24 hours.
- Noticeably cooler behind a cold front Saturday, and continued chilly Sunday.
Starting out the day, zonal flow is in place over the High Plains/Central High Plains. An upper trough is situated over central California. Winds will increase behind a cold front moving across the center of the nation today. The cooler temperatures will settle in on Sunday, with highs once again around normal (mid-30s) and lows in the mid- teens to low 20s.
This low will spin off upper level disturbances which will travel across a ridge axis situated over Texas and eject out on the downstream side. These disturbances will pick up some latent potential energy as they exit the ridge, and before making their way into our area.
539 AM CST Sat Jan 25 2025 (Today) Temperatures have dropped into the upper teens to lower 20s this morning under clear skies throughout the TN Valley, leading to a couple spots of patchy freezing fog formation along river bodies. Increases in cloud cover will likely result late in the afternoon into the overnight hours as a response to southwesterly flow resulting in increased moisture ahead of a cold front.
At the surface, associated cold front is pushing through eastern ND. Today, expect the aforementioned upper disturbance and cold front advance southeastward through our forecast area. With a 35/45kt 850/700mb jet overspreading the area, winds should be on the increase today, particularly after the cold front pushes through given progged sfc pressure rises of greater than 1 mb/hr.
Temperatures this morning are already down in the teens in some areas, but afternoon highs will be close to 30 degrees warmer than our morning lows. There are low rain chances tomorrow and tomorrow night mainly near the TN/AL border as a trough of low pressure tracks along the Gulf Coast and brings additional moisture to the mid state.
(Today and tonight) A cold front has moved into northwestern Oklahoma this morning and will move slowly southeast through the day. Cool air filtering in behind the front will keep high temperatures cooler than yesterday north of the front with highs generally in the 40s, while temperatures will be warmer than yesterday south of the front with highs in the 50s. Once the front reaches southeast Oklahoma late tonight or very early Sunday, there is at least some low chances of showers in southeast Oklahoma, although the higher chances will be farther southeast.
- A ridge of high pressure will push into the area, so a warming and drying trend is expected to begin Sunday. WEATHER PATTERN OVERVIEW: A Winter Weather Advisory is in effect in response to the cold front aiding in producing snow showers and strong winds, but this activity will eventually end this morning. Although a high pressure system moving in from Saskatchewan will bring temperatures down slightly today, an upper ridge will build in slowly from the west. The pattern will remain the same most of the week due to an upper trough lingering over the western United States.
This trough axis will continue to slide southeast throughout the day today.
537 AM CST Sat Jan 25 2025 (Today through Sunday) Dry conditions expected for the next 24 hours as high pressure briefly sets up over the area. A warm front will pass to our north with an approaching cold front Sunday morning. The high pressure to our east holds firm for much of the day on Sunday, keeping the front just to our north and west. Highs today will be in the low 50s for much of the area with generally sunny skies. Highs on Sunday will be in the 40s across the 50s in the northwest as cloud cover and rain chances keep them on the cooler side.
These SRLY winds will allow for warmer temps and increasing moisture across the state for this Sat. Rain chances look to remain low through this afternoon until a cold front approaches from the N/NW tonight into Sun. mainly by drier air starting to push back south behind the cold front. Temps will drop for Sun as a result of the cooler/drier air.
616 AM EST Sat Jan 25 2025 High pressure building across the Southeast will maintain dry weather with slowly warming temperatures through Sunday.
(Today) Temperatures have dropped into the upper teens to lower 20s this morning under clear skies throughout the TN Valley, leading to a couple spots of patchy freezing fog formation along river bodies. Increases in cloud cover will likely result late in the afternoon into the overnight hours as a response to southwesterly flow resulting in increased moisture ahead of a cold front.
655 AM EST Sat Jan 25 2025 Clouds will increase and thicken ahead of a weak cold front which is forecast to pass southeast across the area tonight into Sunday.
Above normal temperatures will continue tonight, with lows only dropping into the lower to upper 40s, much warmer than what we have seen the past week. With the passing cold front and widespread rain chances on Sunday, temperatures will be slightly cooler than today, but still be in the the 50s across the region.
Areas where winds became calm have dipped to the lower 20s. High pressure is located over the Southeastern U. Southwesterly winds become breezy today ahead of a dry cold frontal passage tonight. High pressure drops from the Dakotas towards the region Sunday bringing a temporary cooling to near normal temperatures for Sunday. Troughing digs in the east early week though local 500mb levels remain fairly steady.
(Today through Sunday night) Our weekend cold front is currently progressing through the CWA this morning. Subfreezing highs are expected for the far northwest (Dallam, Cimarron, and parts of Hartley county), while the rest of the CWA will range in the 30's to lower 40's.
- Benign high pressure/air quality degrading this coming week.
With many areas at or even below freezing. This afternoon will warm up to the low to mid 60s and the frigid temperatures of the morning will just be a memory.
High pressure over Georgia and the Carolinas today will send warming southwest winds into the Mississippi and Ohio Valleys. Tonight a weak, dry cold front will enter the region from the northwest, lined up from Cleveland to Louisville to Dallas by dawn Sunday.
- A cold front passes this afternoon, with west winds gusting to around 30 MPH.
A few snow squalls will be possible, with the highest chances across the Arrowhead this afternoon.
928 AM EST Sat Jan 25 2025 Clouds will increase and thicken ahead of a weak cold front which is forecast to pass southeast across the area tonight into Sunday.
In the lower-levels, light SSW flow (around a high situated across southern GA) is anticipated at the surface, with WSW flow predicted to increase to 15-25 knots at the 850-mb level. Resultant warm advection within the boundary layer, combined with abundant sunshine (prior to the onset of thicker high-level clouds) will allow temperatures to climb into the u40s-l50s in the valley (mid 40s in the higher terrain of northeast AL/southern TN).
Currently - Strong high pressure moving through the far southeastern United States, along with nocturnal effects brought about fresh northerlies through the night. This brought about a very cool morning in the Keys with temperatures ranging broadly in the lower 50s with dew points ranging in the upper 40s. The shallow Florida Bay waters have also cooled further, falling over 5 degrees into the lower to mid 50s. Strong high pressure driving steadily southeastward through the southeastern United States to the Carolina Coast. Expect winds to be slower to fall and faster to veer over the warmer Atlantic side waters, while the converse is true over the very cool gulf and bay side waters.
- Cold front moving through between midnight and 5 am tonight.
Mid morning surface analysis had a >1030mb high centered over the Florida panhandle that will continue to ridge back across the southern portions of our CWA today. This low will spin off upper level disturbances which will travel across a ridge axis situated over Texas and eject out on the downstream side. These disturbances will pick up some latent potential energy as they exit the ridge, and before making their way into our area.
Overnight lows will be warmer than past nights due to increased cloud cover. East Texas and Northwestern Louisiana will likely drop to the mid to upper 40s tonight, with other areas expecting to cool more into the low 40s. Sunday high temperatures will be slightly cooler than today due to the rainfall, with lows following suit in the upper 30s to low 40s.
At the surface, a strong (1030mb) ridge of high pressure was positioned over the southeast while a quasi-stationary front was draped over the southern Plains. An attendant wave of frontal low pressure along the boundary was positioned over western OK. As southern plains front slips southeast to the Lower MS Valley later in the day Sunday and into Sunday night, forecasters begin to see the probability of showers re-entering the forecast. With the high off to the east and an evolving light onshore flow off the Gulf, overnight lows are favored to trend more modified than what we have seen over the past several nights. Highs Sunday warm mostly into the lower to mid 60s.
Despite slow approach of cold front and decent upper level energy, precipitation has yet to reach the ground as high cloud bases (10,000 ft or so) and dry layer below are resisting even flurries at this point. Thinning/clearing of the cloud cover is noted upstream, which should allow temperatures to warm somewhat, reaching the low to mid 30s. Cold front in association with this system drops through the area late day but until then swrly low level flow/mixing expect temps to crack freezing this aftn. Briefly colder tomorrow as plains centered ridge builds in. After 12z Sun, cigs will temporarily lower to around 5000 ft with a weak upper level trough axis passage and begin improving towards the end of this period.
With the increasing temperatures to near or above freezing, fog and stratus will likely become an issue through the work week.
Slightly less wind Sunday and a bit cooler. Extensive mid and high clouds are moving into the region this morning, ahead of the upper low dropping down the California coast. An upper low will close off near San Francisco this afternoon and then wobble down the coastline for the next 24 hours.
Rain, snow, mixed precipitation, and freezing rain all appear possible at this time. (Today through Sunday night) Our weekend cold front is currently progressing through the CWA this morning. Subfreezing highs are expected for the far northwest (Dallam, Cimarron, and parts of Hartley county), while the rest of the CWA will range in the 30's to lower 40's.
1233 PM EST Sat Jan 25 2025 Clouds will increase and thicken ahead of a weak cold front which is forecast to pass southeast across the area tonight into Sunday.
203 PM CST Sat Jan 25 2025 - A dry cold front tonight will cool temperatures back down to near to slightly below normal for Sunday and Sunday night.
With high pressure moving into North Dakota, skies have cleared out. With the cold frontal passage well behind us, winds are calming down to gusting 15-20 mph. Aloft the pattern is a weak northerly flow, with a tilted ridge to our west. Stronger northwest flow will setup over the northern Plains, but warmer air at 850mb and breezy winds will mix the warmer temperatures to the surface.
(Rest of today and tonight) Cold front located just north and west of I-44 early this afternoon will continue to move south and east into this evening. Otherwise, slightly cooler air will filter south across the area with overnight lows dropping back below freezing across all but far southeast Oklahoma. There the front will be slower to move through, thicker cloud cover will be present and temperatures are expected to remain above freezing, in the middle 30s.
245 PM EST Sat Jan 25 2025 A weak cold front will move through the Ohio Valley tonight with high pressure then building into the region through the first part of the upcoming week. Otherwise, a weak cold front will move east across the region tonight. With some CAA developing behind the front late, lows tonight will range from the lower 20s northwest to the upper 20s southeast. The cold front will move off to our east through the day on Sunday with some weak CAA continuing across the area.
Despite slow approach of cold front and decent upper level energy, precipitation has yet to reach the ground as high cloud bases (10,000 ft or so) and dry layer below are resisting even flurries at this point. Thinning/clearing of the cloud cover is noted upstream, which should allow temperatures to warm somewhat, reaching the low to mid 30s. Cold front in association with this system drops through the area late day but until then swrly low level flow/mixing expect temps to crack freezing this aftn. Briefly colder tomorrow as plains centered ridge builds in.
(Tonight through Sunday night) High pressure to the east has kept onshore flow over South Texas, increasing our temperatures and moisture. Meanwhile, a cold front has begun to push south through Texas this afternoon.
- Meteorological Overview: A somewhat stagnant but overall mild and dry weather pattern develops through much of the week ahead as a large upper level ridge centered offshore of the Pacific coast gradually tilts east into western Canada and the NW US while troughing undercutting the ridge across the SW US sets up short term blocking pattern.
- Warmer for early and mid week. The cold frontal boundary will continue to shift southeast through this evening, bringing those cooler temperatures to locations further southeast by Sunday when highs in the 30s will be seen areawide. High pressure will build over the region leading to clearing conditions and diminishing winds.
(Through Sunday) High pressure across the southeast US dominates throughout the near term. Expect daytime highs generally in the low to mid 60s with overnight lows generally in the upper 20s to mid 30s.
Updated at 1201 PM CST Sat Jan 25 2025 - Warmer temperatures in the days ahead. This morning was our last dip into the teens for the foreseeable future! Tonight might see comparatively warm, with lows only in the low 30s. Expect highs to be just a couple of degrees cooler than today.
- Warmer Today, with a cold front coming through tonight.
1135 AM CST Sat Jan 25 2025 - Warmer Today, with a cold front coming through tonight.
(Today through Sunday) Dry conditions expected for the next 24 hours as high pressure briefly sets up over the area. A warm front will pass to our north with an approaching cold front Sunday morning. The high pressure to our east holds firm for much of the day on Sunday, keeping the front just to our north and west. Highs today will be in the low 50s for much of the area with generally sunny skies. Highs on Sunday will be in the 40s across the 50s in the northwest as cloud cover and rain chances keep them on the cooler side.
Updated at 215 PM CST Sat Jan 25 2025 - Clearing and cooler for Sunday.
Upper level flow is set to become zonal today and into tomorrow with high pressure setting up just off the coast. Overnight lows tonight will dip below freezing one final time for the foreseeable forecast.
A strong high pressure system over the Southeast will bring warmer, rain free conditions through most of the week, with each day warmer than the last. By midweek the high pressure will shift east and weaken as another cold front attempts to pass over the area. Low temperatures increase from the low 40s/50s to start the week, to the low 50s/60s by the end of the week.
High pressure will weaken as it shifts south and east over the area resulting in a slow warming trend and continued dry conditions.
1139 AM CST Sat Jan 25 2025 Mid morning surface analysis had a >1030mb high centered over the Florida panhandle that will continue to ridge back across the southern portions of our CWA today. This low will spin off upper level disturbances which will travel across a ridge axis situated over Texas and eject out on the downstream side. These disturbances will pick up some latent potential energy as they exit the ridge, and before making their way into our area.
1043 AM CST Sat Jan 25 2025 - Noticeably cooler behind a cold front Saturday, and continued chilly Sunday.
Associated with this trough is some frontogenesis between 700 and 500mb. That combined with the lower-level clouds out there will provide enough light to have snow showers this afternoon and early evening. Due to the low QPF from these showers, guidance does not have a good handle on this so we have raised PoPs through the afternoon following the area of snow showers across the central portions of the CWA. Similar to today, we will likely need to raise PoPs due to the low QPF nature of this flow regime.
300 PM EST Sat Jan 25 2025 High pressure will remain to the south through Sunday.
1109 AM CST Sat Jan 25 2025 (Today through Sunday) Dry conditions expected for the next 24 hours as high pressure briefly sets up over the area. A warm front will pass to our north with an approaching cold front Sunday morning. The high pressure to our east holds firm for much of the day on Sunday, keeping the front just to our north and west. Highs today will be in the low 50s for much of the area with generally sunny skies. Highs on Sunday will be in the 40s across the 50s in the northwest as cloud cover and rain chances keep them on the cooler side.
High pressure gives way to zonal flow tonight as a weak disturbance approaches from the southwest.
The low level pressure gradient and wind fields keep the winds weak tonight and Sunday with normal diurnal patterns to prevail before sunrise Sunday morning. I will leave the highlights going, as is, for this update. The high mountain valleys will not get extreme cold tonight with all the cloud cover expected.
908 PM EST Sat Jan 25 2025 High pressure will remain to the south through Sunday.
333 PM CST Sat Jan 25 2025 Tonight and Sunday: Warmer through the period with widespread rain after dry weather tonight. Mid afternoon surface analysis still had a >1030mb high centered over the Florida/Georgia border that will continue to ridge back across the southern portions of our CWA through Sunday. This will maintain in a return flow that will work to increase low level moisture back across our region ahead of an approaching low pressure system.
(Tonight) After a near climatological normal day with afternoon highs in the lower 50s, temperatures have fallen quickly this evening down into the upper 20s to lower 30s. In fact, overnight forecast lows are not much lower than the current (02z) temperatures, which are nearly 10 degrees warmer than this morning lows.
An area of high pressure situated across the southeastern U. High pressure will weaken as it shifts south and east over the area resulting in a slow warming trend and continued dry conditions.
305 PM CST Sat Jan 25 2025 - A bit cooler tomorrow, then milder temperatures to start the work week, with periods of breezy winds. - A cold front passes through the rest of the afternoon, with flurries and light snow showers possible, mainly north of I-94.
During the late evening and early morning hours on Sunday, showers and perhaps a few thunderstorms will expand in coverage from south-central TX northeastward into the Mid-South region, with this activity occurring in the vicinity of a cold front that will drop slowly southeastward through the southern Great Plains.
602 PM CST Sat Jan 25 2025 - A dry cold front tonight will cool temperatures back down to near to slightly below normal for Sunday and Sunday night.
