The highest rainfall totals have been in the northwest with some locations including Clarksville picking up around 3 inches. Additional scattered showers and storms are expected to develop this afternoon as the trough moves through the area. Low level lapse rates will be steep with the cooler temperatures aloft which is conducive for some low top storms. The trough will clear the area this evening leading to a drier pattern. Saturday will be about 10 degrees cooler than today.
By daybreak, the W to NW winds will be more uniform over these eastern counties, and the high cloud canopy will have shifted east. Surface ridging settles over the area tonight, and the efficient radiational cooling and low dew points could send a few protected valleys briefly to the freezing mark. A general light west wind should keep most exposed areas comfortably above freezing and even into the low 40s.
This will slowly shift east through midday and early afternoon with the low level jet axis. The 5h trof and secondary surface trof will pivot into the region this afternoon.
646 AM EST Fri Jan 31 2025 (Today through Saturday) High pressure centered off the Mid Atlantic coast will move off to the east today, while a cold front associated with a system forecast to move across the northeast US will approach the area on Saturday, eventually stalling over the Lake Okeechobee region.
At 09z the cold front has made it south thru the entire forecast area.
A closed low at the 500 mb level will move east across the Plains today, with a vort max cutting across SE Texas as it does so. Winds will take a more southerly component in the lower levels going into Saturday, making highs a few degrees warmer. Lows will be a touch warmer on Saturday night. Inland areas will be in the 40s with the coast in the low 50s.
409 AM EST Fri Jan 31 2025 A low pressure system will bring rain to the area today. A cold front will bring an end to the rain this evening and usher in cooler air for Saturday. As the low level jet shifts east the widespread rain will taper off this morning - with a threat for scattered showers continuing thru the day. On the warm side of the system - highs to range from the upper 40s northwest to the lower 60s south of the Ohio River. Areas along and north of I-70 should bottom out in the mid and upper 20s while areas along and south of the Ohio River drop to the lower and middle 30s. Northwest to west mid level flow with a large area of high pressure passing thru the Great Lakes Saturday.
531 AM CST Fri Jan 31 2025 (Friday through Saturday) Surface based convection along a cold front continues to depart east of the FA this morning as a band of mid and high clouds remains situated across the region, virtually splitting the CWA in two.

(This evening through Saturday) Rain showers are ongoing across much of Central Alabama behind a cold front, which is currently working through southeastern Central Alabama.
(Rest of today through Saturday) An area of high pressure centered off the Mid-Atlantic will move eastward today. A weakening cold front associated with an area of low pressure forecast to move across the northeast US will approach the area on Saturday, eventually stalling around the Lake Okeechobee region.
Through this Evening: Rain showers associated with an passing trough and associated cold front will continue to affect north and central Georgia through this evening.
(This evening through Saturday Night) Dry and warmer than normal conditions will remain in place as the weekend begins across the Four State Region. This is due to post- frontal surface ridging making its way across Texas. As the ridge axis shifts east into the area, winds will slacken overnight tonight, allowing for some radiational cooling and enhanced fog development potential areawide.
7AM Update: Across the Spokane metro area, air temperatures and dewpoints have warmed above freezing, likely ending any chance for snow early this morning. Pockets of freezing rain will still be possible especially across the west plains of Spokane.
Have a wonderful Friday morning! (Today through Saturday) High pressure centered off the Mid Atlantic coast will move off to the east today, while a cold front associated with a system forecast to move across the northeast US will approach the area on Saturday, eventually stalling over the Lake Okeechobee region.
- Patchy fog will develop tonight into early Saturday morning, with the highest chances (30-60%) of visibilites less than 1 mile generally along and west of the I-49 corridor and into west- central Missouri.
1142 AM CST Fri Jan 31 2025 (Tonight through Saturday night) North to northwesterly flow will continue through today as high pressure builds in from the west. High temperatures today will be in the low 70s along the coast to around 80 over the Brush Country. Conditions will be much the same for Saturday as for today, though the high pressure will slide to the east resulting in light onshore flow by Saturday afternoon.
350 PM EST Fri Jan 31 2025 High pressure will build into the region bringing cooler air for Saturday. Eventually, a cold front will push south of the area overnight thereby ending shower chances and warm conditions later tonight. High pressure skirts by to the north of the Ohio Valley on Saturday. Northeasterly flow south of the high will keep temperatures near seasonal averages under a mix of sun and clouds.
The tail end of this weakening cold front will pass across the region tonight, accompanied by a broken line of showers and a few embedded thunderstorms, mainly across inland SE GA and Suwannee Valley.
Saturday's highs are forecasted to reach the lower 70s across the Hill Country, mid 70s across the I-35 corridor and coastal plains and lower 80s over the southern part of the Rio Grande. Expect another clear night for Saturday evening with southerly flow throughout the period that will result in overnight lows in the lower to upper 40s.
However, confidence is low as there is still a lot of variability that could impact temps and precip types, particularly later in the week as high pressure and colder air finally make a southward return. Low pressure center will track over or just south of KFWA this afternoon with drizzle and times of fog.
Meanwhile, inland locations climb up into the low to mid 80s with a breeze.
7AM Update: Across the Spokane metro area, air temperatures and dewpoints have warmed above freezing, likely ending any chance for snow early this morning. Pockets of freezing rain will still be possible especially across the west plains of Spokane. Temperatures for GEG/SFF have warmed above freezing with rain expected to continue through the morning. A mix of freezing rain and snow will be possible for the the Basin and the Palouse this morning before transitioning to rain late morning.
Lastly, winds remain from the southeast for now as a sprawling ridge centered east of Bermuda continues to exert its influence across our area. Meanwhile, an attendent cold front that extends into the northeast Gulf will slowly slide southward. The combination of the approaching front and the retreating ridge will result in winds going briefly light and variable on Saturday. Moisture will continue to get pulled up from the western Caribbean as a new, weaker ridge develops across the extreme southeastern Gulf and Florida Peninsula. Breezes will then shift to the northeast to east as a decaying cold front approaches from the north. High pressure will once again build in over the Eastern Seaboard by the start of the work week allowing breezes to gradually freshen and veer back to the east.
1109 AM CST Fri Jan 31 2025 - A bit cooler with highs in the upper 30s and 40s today but well above normal temperatures in the 40s and low 50s on Saturday.
- Stronger Arctic front late week with much cooler weather returning.
1137 AM CST Fri Jan 31 2025 As of 10:15 AM CST, temperatures continue to rise into the lower 60s under some isolated mid-level cloud decks. By this afternoon, temperature maximums will reach the upper 60s (warmer than normal for this time of the year) with westerly winds at 10-15 mph. A weak cu field is expected to develop this afternoon generally along and N of the I-20 corridor this afternoon, with some additional areas of AC associated with the cold core upper trough that will swing through the region. While the AC should diminish by 00Z as the trough exits the region, a few cu may linger into the evening across portions of SW AR on the backside of the trough before diminishing.
1034 AM CST Fri Jan 31 2025 As of 10:15 AM CST, temperatures continue to rise into the lower 60s under some isolated mid-level cloud decks. By this afternoon, temperature maximums will reach the upper 60s (warmer than normal for this time of the year) with westerly winds at 10-15 mph. /16/ (Friday through Saturday) Surface based convection along a cold front continues to depart east of the FA this morning as a band of mid and high clouds remains situated across the region, virtually splitting the CWA in two.
Another round of showers, and perhaps a few thunderstorms, are expected to develop as the upper-level trough axis swings across the region. Cold temperatures aloft will enhance mid-level instability, yielding steep laps rates in the lowest 10-12 kft. Southwest winds will gust up to 20 mph, shifting northwest this evening in the wake of a weak Pacific cold front. An upper-level trough will bring the potential for the development of isolated to scattered showers across portions of the Mid-South this afternoon.
A weak cold front moves through the area meanwhile, with southerly winds at 5 to 10 knots briefly switching to the northwest as the showers move through, then returning to a south/southwest direction before becoming a light northwest flow tonight.
THe highest rain chances should stay north and west of the TAF sites. Meanwhile, inland locations climb up into the low to mid 80s with a breeze.
(Tonight) An upper trough will pivot quickly east this evening through the OH and TN valleys. Showers are expected to develop this afternoon in northern MS and western TN which will also move through this evening with the trough. Overnight lows will be in the lower 40s for most areas, with upper 30s in a few valleys.
(Tonight through Saturday night) There's a Mid-level Low centered near the TX/OK border this morning with a trough extending over northern Mexico to the Baja peninsula. Recent model runs have the low further south resulting in no rain chances for the short term. However, should the low track further north over our CWA, PoP's would increase this weekend. Overnight lows tonight will range in the low 40s (inland) to 50s (along the coast) and will range in the mid 40s to 50s tomorrow night.
1208 PM EST Fri Jan 31 2025 A cold front will bring an end to the rain this evening and usher in cooler air for Saturday. Eventually, a cold front will push south of the area overnight thereby ending shower chances and warm conditions later tonight. High pressure skirts by to the north of the Ohio Valley on Saturday. Northeasterly flow south of the high will keep temperatures near seasonal averages under a mix of sun and clouds.
(Now through Saturday Night) An upper trof over the eastern states weakens and exits off into the western Atlantic through Saturday morning. Showers currently over the easternmost portion of the area, associated with a pre-frontal surface trof, exit to the east by late this afternoon. Lows tonight range from the lower 40s inland to the mid to upper 40s at the coast, then Saturday night will be a bit cooler and range from around 40 well inland to the mid 40s at the coast.
/Issued 1253 PM CST Fri Jan 31 2025/ /Through Saturday Afternoon/ As an area of low pressure continues to depart our region, leading to breezy westerly winds throughout North and Central Texas.
634 PM EST Fri Jan 31 2025 High pressure will build into the region bringing cooler air for Saturday. Eventually, a cold front will push south of the area overnight thereby ending shower chances and warm conditions later tonight. High pressure skirts by to the north of the Ohio Valley on Saturday. Northeasterly flow south of the high will keep temperatures near seasonal averages under a mix of sun and clouds.
Southerly winds will return Saturday in response to deepening low pressure across the Plains. 79 Previous Discussion: /Through Saturday Afternoon/ An area of low pressure continues to depart our region, leading to breezy westerly winds throughout North and Central Texas.
A trough feature extending south of an area of low pressure over IN/OH should sweep to the east, helping to end shower chances from west to east during the course of the mid and late evening.
High pressure pushes east of the state Saturday afternoon, ushering in onshore flow and WAA.
However the difference will be that the low temperatures are expected to be mostly in the 50s for all of Deep South Texas and the Rio Grande Valley. With mostly clear skies, the high temperatures for tomorrow are expected to be in the mid to upper 70s. Afterwards, the risk of rip currents becomes low as the wave heights decrease along the Lower Texas Coast.
558 PM CST Fri Jan 31 2025 (00Z TAFS) Cold front has cleared the area with all convective activity now well east of the TAF sites. (Now through Saturday Night) An upper trof over the eastern states weakens and exits off into the western Atlantic through Saturday morning. Showers currently over the easternmost portion of the area, associated with a pre-frontal surface trof, exit to the east by late this afternoon. Lows tonight range from the lower 40s inland to the mid to upper 40s at the coast, then Saturday night will be a bit cooler and range from around 40 well inland to the mid 40s at the coast.
523 PM CST Fri Jan 31 2025 (This evening through Saturday Night) Dry and warmer than normal conditions will remain in place as the weekend begins across the Four State Region. This is due to post- frontal surface ridging making its way across Texas. As the ridge axis shifts east into the area, winds will slacken overnight tonight, allowing for some radiational cooling and enhanced fog development potential areawide.
525 PM CST Fri Jan 31 2025 (Tonight through Saturday night) There's a Mid-level Low centered near the TX/OK border this morning with a trough extending over northern Mexico to the Baja peninsula. Recent model runs have the low further south resulting in no rain chances for the short term. However, should the low track further north over our CWA, PoP's would increase this weekend.

1048 AM CST Sun Nov 9 2025 Updated at 1128 PM CST Sat Nov 8 2025 - Significantly colder temperatures behind a strong cold front Sunday through Monday. (Sunday) A strong cold front has entered northeast Oklahoma late this evening and will continue south across the rest of the forecast area overnight. Afternoon high temperatures will mostly be in the lower 40s to lower 50s.
resulting in most areas seeing sub-freezing conditions -Wind chills dropping into the lower teens tonight/Mon morning for some locations in the higher terrain of the Ozarks -Mainly dry conditions for the next several days -Warming conditions for the middle to latter half of the week. with temps back in the 60s and 70s for highs The strong cold front has moved SE through the state as of early this Sun morning. with wind chills dipping into the lower teens across NWRN sections.
1122 AM CST Sun Nov 9 2025 - A Freeze Warning is in effect through tomorrow morning, as low temperatures fall into the middle 20s north to near-freezing south. Low temperatures tonight will plummet into the middle to upper 20s north, while sites to the south straddle the freezing mark by daybreak. The upper level trough has plunged south towards the coast as anticipated, enveloping the entire ArkLaTex in a cold continental airmass.
A high amplitude pattern continues across CONUS, with a strong 588- dm ridge of high pressure over the Western US, and a 528-dm trough over Western Ontario. Rain showers continue through the afternoon with the high for the day already occurring earlier this morning. Cold air from behind the cold front will continue to move into the region through the afternoon and evening. Lows tonight will bottom out in the low to mid 20s across the area.
Cold, breezy, and downright raw conditions are being observed over central Illinois this afternoon with temperatures sitting in the low to middle 30s and wind chills in the 20s. Overnight lows will be a solid 10-15 degrees cooler than normal with values dipping down into the low to mid 20s. Cold and breezy weather remains through Monday, with daytime highs in the low to middle 30s.
1252 PM CST Sun Nov 9 2025 - Moderate to heavy lake effect snow is expected this afternoon and overnight in the higher elevations of Iron and Ashland counties, with 3 to 8 inches of new snow possible.
1249 PM CST Sun Nov 9 2025 Updated at 1247 PM CST SUN NOV 9 2025 - There is a medium to high chance of freezing temperatures tonight, focused on the northern half of Central Alabama.
1116 AM CST Sun Nov 9 2025 - Gusty north-northeast winds and much cooler temperatures are expected today in the wake of a strong cold frontal passage.
- Cold and blustery on Sunday with highs in the low 30s and northwest winds gusting 25-30+ mph.
A deep and anomalous upper-level trough is digging across the western Great Lakes this afternoon. This trough, combined with strong high pressure building in from the Dakotas, has tightened the pressure gradient across the region, leading to gusty northwest winds to 25 mph. However, a slight backing of the low-level winds has since pushed this main band east of the peninsula. As the upper trough shifts east tonight, lake effect parameters will become less favorable.
Yesterday's cold front has moved through the area and temperatures are dropping as the anomalously cold airmass surges into the region. The tight surface pressure gradient is resulting in elevated winds and a continuation of the 20-30 mph gusts that entered the region immediately behind the cold front.
114 PM EST Sun Nov 9 2025 Low pressure tracking through the Great Lakes will bring rain showers today.
- Warm and dry beginning Monday with highs 10-15F above average The Northern US Plains remains in northwesterly mean flow aloft at 500 mb height analysis as a deep low pressure sits over the Upper Great Lakes to the east and a notable high pressure centered over the Southwest extends a high amplitude ridge into the Pacific NW. While the low-level airmass aloft does warm through tonight, seasonable chilly temperatures will occur into early Monday morning over mainly the SD Plains. Forecast minimum wind chills tonight drop into the low-single digits above zero closer the Missouri River valley region, while closer to the mid- teens towards the WY/MT stateline region on the Plains. These conditions will help to create forecast surface temperatures Monday daytime in the low-50s along the Missouri to mid-60s in northeast Wyoming and downslope of the Hills.
A warming and drying trend will continue into Monday as a ridge of high pressure continues to build aloft and offshore flow at the surface continues. Models are still indicating a slight increase in offshore flow Monday but still with very minimal upper support so for the most part a very similar day as today except likely a few degrees warmer.
Water vapor this afternoon shows a deep trough over eastern portions of CONUS. This cold snap will be short lived, as ridging will start building in on Monday.
The thermal trough will actually be dragged further over the area tonight by a strong short wave over western Wisconsin embedded in the broader long wave trough. The turnaround in temperatures will be quite pronounced with a fast-paced pattern in the wake of the long wave trough's departure.
This ridge will bring not only dry conditions, but also a much colder airmass into the region. Cold air advection on the leading edge of the ridge will usher in 850 mb temperatures in the -6 to -10 C range across central and western Nebraska. This will result in surface temperatures ranging from the low 30s in north central Nebraska to the mid 40s in southwest Nebraska today. As upper level ridging continues to build across the western US, temperatures will gradually rise back to above normals bringing an end to the couple days of colder temperatures. Highs on Monday will be on the cooler side across the east (low 40s) as warmer air slowly pushes in to the west (upper 50s to low 60s).
Updated at 133 PM CST Sun Nov 9 2025 - Chilly tonight into Monday morning, with freezing temperatures expected across portions of the northern Permian Basin and in the higher terrain.
