This trough will be slow moving, with rain chances ebbing and flowing for most of the next 24-36 hours. However, no accumulation or impacts would be anticipated, as temperatures will quickly rise above freezing. With that being said, overnight lows will be slower to respond, with lows tonight ranging in the low-30s and 40s.
613 AM EST Sun Feb 23 2025 High pressure will bring dry weather and a slow moderation of temperatures through Monday.
A passing mid-level trough will quickly shunt the last of these light showers east with dry conditions likely around sunrise. Warmer temperatures are expected today with highs in the 70s west and the 60s and upper 50s east. Benign weather is expected Monday with even warmer temperatures across the area in the 70s to low 80s due to the return of southerly flow.
This will be a chilly, soaking rainfall event with one to two inch amounts common along/south of the highway 84 corridor, up to one inch amounts along the I-20 corridor, and lighter amounts farther north.
Fair dry weather will continue today as high pressure holds on as it moves east away from the southeast U. Tonight into Monday we'll see quick deterioration as developing low pressure over the western gulf moves east spreading clouds and rain across the region.
(Today through Monday) Key Messages: - Much warmer today and Monday! The inverted trough that brought in our chilly rain yesterday will continue to move offshore today as a mid-level trough swings east through north Texas, ending rain chances through midday. Lows will once again be chilly overnight as high pressure builds in tonight. Fog is expected to lift by midday Monday and even warmer temperatures are expected with highs in the 70s to around 80 degrees across the Rio Grande Plains.
413 AM MST Sun Feb 23 2025 - Gusty winds from 50 to 60 mph today over the higher east slopes of the Front Range.
243 PM EST Sun Feb 23 2025 Dry high pressure remains over the region early this week.
1136 AM CST Sun Feb 23 2025 (Today through Monday) Key Messages: - Much warmer today and Monday! The inverted trough that brought in our chilly rain yesterday will continue to move offshore today as a mid-level trough swings east through north Texas, ending rain chances through midday. Lows will once again be chilly overnight as high pressure builds in tonight. Fog is expected to lift by midday Monday and even warmer temperatures are expected with highs in the 70s to around 80 degrees across the Rio Grande Plains.
Sufficient radiational cooling will help bring Monday morning low temperatures down to near freezing.
There is some dry air in the low levels that will act to keep most of the snow to flurries or a brief period of light snow. We'll also see a warming trend Monday due to south winds increasing ahead of the trough.
By the middle of the week, an amplified ridge will build and move into the intermountain west.
310 PM EST Sun Feb 23 2025 High pressure exits tonight with southwesterly winds taking hold Monday.
This is supported by wind observations along the Reef with east northeast winds near the Lower Keys and north northeast winds near the south edge of the Upper Keys. Mostly clear skies have allowed temperatures to quickly jump up to the lower to mid 70s after upper 60s were observed shortly after sunrise. While this trouble brews, high pressure across the southeast CONUS will maintain gentle to moderate northeast to east breezes across the Florida Keys and its coastal waters. An area of weak low pressure is expected to develop over the northwestern Gulf later today and tonight.
Away from the keys, a nebulous low churns off the northwest Gulf coastline with an upper level trough gradually associating itself with the surface system as it moves east into Louisiana. A cold front will form with this development but the majority of the action is expected ahead of its passage.
250 PM EST Sun Feb 23 2025 High pressure remains in control of the weather tonight and into Monday night.
Rainfall totals will generally stay under an inch, with the higher totals and thunderstorms likely staying offshore. Low temperatures tonight will be in the mid 40s to low 50s tonight, with highs tomorrow in the low to mid 60s.
1253 PM EST Sun Feb 23 2025 High pressure will bring dry weather and a slow moderation of temperatures through Monday.
1251 PM EST Sun Feb 23 2025 A cold front will cross the region today through early tonight. High pressure will cross the region Monday.
1246 PM EST Sun Feb 23 2025 A cool morning across the peninsula with temperatures in the low 40s to around 60 degrees south. Afternoon highs today will warm up into the low 70s to near 80s.
Temps this morning may start off near or just below freezing for a couple hrs to see some potential for a rain/FZRA mix across the far south. A new cold front will move SE through the state on Wed/Wed night. This clearing will be significant to aviation as it will allow the temperature to cool into the lower 30s overnight.
(This evening through Monday) A short wave trough was currently passing overhead and will move east of the area this evening. Upper level ridging will replace the trough through the day on Monday leading to warmer temperatures. Weak surface cyclogenesis will develop in eastern New Mexico with several surface pressure troughs draped across West Texas.
Farther south along the US-395 corridor from Lassen County southward to Reno-Carson City, we could see a shorter period of wind gusts around 55 mph in wind prone areas Monday afternoon, but overall the strongest winds look to remain farther north with the main trough passage across southern Oregon occurring Monday evening-night. Snow levels remain above 7500 feet but a couple flurries along the highest Sierra peaks can't be ruled out. Wind prone areas will likely see gusts upwards of 50 mph while ridgetops will see gusts from 65-85 mph, with the strongest gusts north of Tioga Pass.
1257 PM EST Sun Feb 23 2025 High pressure will weaken over the Southeast through mid-week.
Monday will feature more sunshine by late morning after mixing dissipates the low clouds and fog. Warmer temperatures are on tap as well with highs generally in the 60s with some lowers 70s extreme southwest areas.
The rest of this afternoon will feature more mild temperatures above to well above freezing along with increasing winds out of the southwest. Guidance also continues to keep temperatures just above freezing (owing to warm air advection with increased winds helping mix above freezing temperatures aloft toward the surface), which favors rain as the dominate precipitation type, albeit a cold rain with temperatures in the mid 30s. Will still need to keep an eye on potential for icing with sub-surface temperatures below freezing, but this is a low chance scenario (10%). Thinking with increasing winds this morning and the high clouds quickly moving in, the fog will not last more than another couple of hours.
High pressure builds back into the area from the south late tonight into Monday.
329 PM EST Sun Feb 23 2025 High pressure will bring dry weather and a slow moderation of temperatures through Monday.
The exception being Wed, where near average temperatures are expected behind a cold front.
1159 AM CST Sun Feb 23 2025 The forecast remains on track with rain being reported at most sites at and south of I-20 in response to a low amplitude trough moving through the area. Highs will crest in the high 40s for sites south of Highway 82 and peak just above 50 north of Highway 82. This will be a chilly, soaking rainfall event with one to two inch amounts common along/south of the highway 84 corridor, up to one inch amounts along the I-20 corridor, and lighter amounts farther north.
Monday morning lows will remain above freezing for the bulk of the CWA given dense cloud cover and light rain in Middle Georgia. Lingering clouds will clear north to south on Monday with mostly clear skies likely for most by afternoon as the trough axis shifts eastward. Highs will warm into the lower 60s areawide, right at normal values for late February.
Skies should be mostly to completely sunny by this afternoon with much warmer temperatures in the mid 50s in our eastern counties up to the low 70s in our west. This will begin a period of significantly warmer weather for our forecast area which will continue through this week.

1222 PM EST Sun Feb 23 2025 (Today and tonight) An upper level trough currently progressing through Texas has spawned a weak area of low pressure in the western Gulf.
Warm and dry weather is expected much of the coming week as a strong ridge of high pressure builds into Arizona.
A warmer afternoon Monday with highs generally a bit above normal. After another cold night tonight, Monday will feature plenty of sunshine with a warmer afternoon as high temperatures reach just above seasonal normals in most locations.
126 PM EST Sun Feb 23 2025 - Slight chance of snow today - Wet and warmer through mid week, then cooler - Slight chance of snow today Skies are currently partly cloudy with high clouds moving across the region. We'll also see a warming trend Monday due to south winds increasing ahead of the trough.
155 PM EST Sun Feb 23 2025 High pressure will continue to impact the area today before shifting east tonight.
1039 AM EST Sun Feb 23 2025 High pressure will bring dry weather and a slow moderation of temperatures through Monday.
Trace amounts are most likely with this activity as conditions remain dry in the lowest levels of the atmosphere.
1221 PM EST Sun Feb 23 2025 Weakening high pressure moving offshore will continue to foster a warmup over the next several days.
(This evening through Monday) High pressure remains over the southern half our region while the North Bay is being impacted by a pair of weather systems. Temperatures this afternoon will warm into the low-to-upper 60s across the North Bay and San Francisco Bay Area with upper 60s to near 80 degrees across the Central Coast. If the North Bay and San Francisco Bay Area stay under cloud cover, temperatures may be a few degrees cooler.
Some areas in southern AR may see visibilities below 1/4 mile with patches of freezing fog. Ridging will build into the area on the backside of the system today and help bring our temperatures to 10-15 degrees above normal for this time of year.
Sunday and Monday Showers are moving across Nevada this afternoon as an upper trough passes to our north.
Some light freezing rain or snow could mix in, but little to no accumulation of snow or ice is expected. Temperatures have warmed above freezing across the state with temperatures ranging from the upper 30s to the upper 40s melting snow. High temperatures could touch the lowers 50s in the south central as clouds continue to clear. Freezing rain is possible in the northwestern half of the state in the morning as the surface will near freezing, but temperatures aloft will remain above freezing melting any snow. Majority of the precipitation will fall as rain as temperatures will warm above freezing.
215 PM EST Sun Feb 23 2025 High pressure will weaken over the Southeast through mid-week.
(This evening through Monday Night) Showers continue to move through the Ark-La-Tx today as an upper- level trough pushes eastward. Rain chances will dissipate by this evening as the trough moves out of the area. Overnight lows will be warmer than they have been, with much of the area being in the 30s. Westerly zones could see afternoon temperatures in the upper 60s while easterly zones will likely remain in the low 60s.
(This evening through Monday) A benign forecast is in store for West Central Texas tonight and Monday, with warmer temperatures continuing. Weak ridging to our west will keep our area in northwest flow aloft through tomorrow. A low level thermal ridge will strengthen by tomorrow, which will result in above normal temperatures areawide.
Valley locations this afternoon have seen temperatures ranging from the mid 60s to the low 70s, highest over the northern San Joaquin Valley.
647 PM CST Sun Feb 23 2025 (This evening through Monday Night) Showers continue to move through the Ark-La-Tx today as an upper- level trough pushes eastward. Rain chances will dissipate by this evening as the trough moves out of the area. Overnight lows will be warmer than they have been, with much of the area being in the 30s. Westerly zones could see afternoon temperatures in the upper 60s while easterly zones will likely remain in the low 60s.
With clear skies temperatures will be allowed to drop back into the lower 40s tonight wit a few locations north potentially dipping below 40. Monday after fog burns off should be a pretty pleasant day with light winds, low humidity and highs in the 70s for much of the area, maybe into the lower 80s west.
229 PM MST Sun Feb 23 2025 - Even warmer Monday, breezy at times, mainly across the mountains.
459 PM MST Sun Feb 23 2025 - Even warmer Monday, breezy at times, mainly across the mountains.

710 PM EST Sun Feb 23 2025 High pressure will bring dry weather and a slow moderation of temperatures through Monday.
Tomorrow, this area is not where we area expecting the lowest, as the lowest RH and strongest winds will be west of the MO River (22- 30%), while more solidly in the 30% range in our area of concern. A few pockets of light freezing rain accumulating to 0.
- The warmer weather is expected to lead to ice movement on area rivers and streams.
641 PM EST Sun Feb 23 2025 Dry high pressure remains over the region early this week.
442 PM MST Sun Feb 23 2025 - Winds will increase over the mountain ridges and east slopes of the Front Range tonight.
541 PM CST Sun Feb 23 2025 (Remainder of today and tonight) There have been no significant changes to the forecast for the remainder of the afternoon since the update earlier this morning, as current radar data indicates the leading edge of light stratiform rainfall (associated with an area of low pressure south of LA) spreading slowly northeastward across central MS. Over the course of the night, a neutrally-tilted mid-level trough (initially across the Lower MS Valley) will turn southeastward into the central Gulf Coast while phasing with an upstream vort max digging across south TX. Abundant mid/high-level cloudiness will initially prevent a rapid nocturnal drop in temperatures, but as skies begin to clear prior to sunrise, temps will descend into the u20s-l30s with patchy freezing fog possible in a few locations.
Warmer than normal conditions will continue through Monday.
627 PM EST Sun Feb 23 2025 High pressure remains in control of the weather tonight and into Monday night.
Overnight lows will be "warmer" than last night owing to increased insulating cloud cover, dropping into the 30s to lower 40s. Monday morning lows will remain above freezing for the bulk of the CWA given dense cloud cover and light rain in Middle Georgia. Lingering clouds will clear north to south on Monday with mostly clear skies likely for most by afternoon as the trough axis shifts eastward. Highs will warm into the lower 60s areawide, right at normal values for late February.
High pressure will keep winds calm and allow for lows 20s to low 30s across the forecast area tonight. A warmer afternoon Monday with highs generally a bit above normal. After another cold night tonight, Monday will feature plenty of sunshine with a warmer afternoon as high temperatures reach just above seasonal normals in most locations.
925 PM EST Sun Feb 23 2025 High pressure remains in control of the weather tonight and into Monday night.
Light precipitation will end this morning across the southeast highlands as a weak ridge of high pressure builds in. Temperatures fall behind the front with highs in the low 40s across most of the Snake Plain and Magic Valley with 30s in the high country.
The first chance for light precipitation returns by early Tuesday as a warmer weather pattern develops through midweek.
This low will advance further eastward through the night. While dew points initially remain broadly in the lower 60s, they are expected to climb into the mid 60s through the night as we tap into increasingly tropical air. Meanwhile, an area of low pressure continues to consolidate over the northern Gulf of Mexico.
Ongoing high wind event will continue to be the focus for the duration of the short term forecast period, alongside notably warmer than average temperatures.
Temperatures will remain warmer than normal through Monday.
1005 PM EST Sun Feb 23 2025 A relatively zonal flow is expected through the middle of the week, with a weak cold front moving across the region late Tuesday.
317 AM EST Mon Feb 24 2025 Weakening high pressure shifting offshore will continue to foster a warmup over the next few days.
Some light freezing rain or snow could mix in, but little to no accumulation of snow or ice is expected.
1030 PM MST Sun Feb 23 2025 - Even warmer Monday, breezy at times, mainly across the mountains.
- These warmer temperatures will support melting of the existing snowpack.
As the disturbance moves further away from the Middle Texas Coast, ridging will take its place as high pressure builds from the south over mainland Mexico. Further promoting clear skies and warmer temperatures. Overnight lows tonight will be a bit warmer, dipping into the mid 40s to low 50s.
343 AM EST Mon Feb 24 2025 High pressure remains in control of the weather today into tonight.
Lows tonight will hover around freezing, which will support further snowmelt overnight. Locations that still have any lingering snowpack will experience slightly cooler temperatures (upper 50s), but will melt most if not all the remaining snow. Tuesday looks to be the warmest day of the forecast period as highs soar into the 60s and even the low 70s across southwestern portions of the area. There is a low chance (15-25%) for rain Tuesday night as a cold front moves through the area.
These showers are associated with the main low pressure system centered over the central gulf. Things clear out Tonight as a large developing high pressure ridge begins to build into the state from the west. This Ridge will keep things dry into the extended periods. Temps are definitely warming with highs Today in the lower to middle 60s and middle 60s to middle 70s Tues.
/26/ (This evening through Monday Night) Showers continue to move through the Ark-La-Tx today as an upper- level trough pushes eastward. Rain chances will dissipate by this evening as the trough moves out of the area. Overnight lows will be warmer than they have been, with much of the area being in the 30s. Westerly zones could see afternoon temperatures in the upper 60s while easterly zones will likely remain in the low 60s.
1220 AM EST Mon Feb 24 2025 High pressure remains in control of the weather tonight and into Monday night.
- Mostly warmer than average temperatures is expected through this forecast period. (Today through Tuesday night) With a trough off to the southeast of the CWA, the Panhandles will be under northwesterly flow aloft today. The cyclonic flow around the low will introduce northerly winds to progressively more of the Panhandles through the day which will help keep temperatures somewhat in check. A cold front will move in from the north Tuesday night and breezy northerly winds will accompany it.
The exception being Wed, where near average temperatures are expected behind a cold front. Monday and Tuesday will be warmer compared to today by 5 to 10 degrees as subsidence warming increases.
Tonight, subsidence will allow for another cool night but definitely warmer than some we've seen recently.
Updated at 225 AM CST Mon Feb 24 2025 - Even warmer today under full sun. (Today and tonight) Height rises in NW flow were well in hand this morning on the heels of a compact upper low shifting southeast across the Hill Country. Barring a few streaks of cirrus today, net subsidence with a dearth of moisture will keep skies sunny all the while lee troughing keeps downslope winds in check. Given NBM's underperformance with highs lately and its moist dewpoint bias evident this morning, opted to run with the warmer and driest model solutions for this pattern.
1055 PM EST Sun Feb 23 2025 Dry high pressure remains over the region early this week.
Will also note some areas could see temps hover around freezing where the fog is ongoing. which may lead to some patchy freezing fog at times. so don't think a Freezing Fog Adv is necessary at this time. a cold front will approach the state from the NW.
Cold front has pushed across the region with the upper level trough and vorticity maximum shifting across northeast Washington into the Northern Panhandle late this evening. Steepening mid level lapse rates ahead of the upper level trough is resulting in developing convection with a handful of lightning strikes occurring.
1054 PM EST Sun Feb 23 2025 A relatively zonal flow is expected through the middle of the week, with a weak cold front moving across the region late Tuesday.
Water vapor imagery shows a broad trough extending from the Ozarks down into Texas and eastward into the mid-Mississippi River valley at this hour. This disturbance will continue to move east through the overnight hours with mid level ridging expected to build in through Tuesday. The warmest locations will be west of I-35 where the lower humidity will enhance the afternoon diurnal cycle.
Low pressure over the northern gulf will drift east southeast today along the stalled boundary and then east across the southern Florida peninsula tonight before moving out into the western Atlantic Tuesday. A few showers could linger Tuesday morning, mainly over the interior, but for the most part drier air will be returning as high pressure builds in from the northwest during the day helping to gradually clear skies.
338 AM EST Mon Feb 24 2025 Quiet conditions continue today along with warmer temperatures. A weak low pressure system brings a mix of rain and some wet snow showers to the region late Monday night into Tuesday.
Warm and dry weather is expected much of the coming week as a strong ridge of high pressure builds into Arizona. This warming trend will continue Monday and Tuesday as high pressure remains over the region.
1254 AM EST Mon Feb 24 2025 High pressure will prevail today.
(Today through Tuesday) A 500mb trough swings off the Texas coast today, with high pressure building at the surface, maintaining very comfortable conditions through the short term period. A slightly cooler day in the upper 60s to near 70 is expected on the island.
Another wave will bring a cold front on Tuesday, along with chances for light rain and gusty winds.
pdf A warm front will extend across central FL from a low over the eastern Gulf this morning. The low will track east along frontal boundary this afternoon. As the low moves over land, drier air will begin to advect south into SE GA this afternoon.
524 AM EST Mon Feb 24 2025 Quiet conditions continue today along with warmer temperatures. A weak low pressure system brings a mix of rain and some wet snow showers to the region late Monday night into Tuesday.
938 AM EST Mon Feb 24 2025 High pressure remains in control of the weather today into tonight.
There are some upstream clouds in Manitoba which will drop into parts of NW MN this morning/aftn associated with a weak cold front and a wind shift to the northwest. Melt all night as temps all areas holding above freezing thru 09z with dew pts also around or just above freezing. Tuesday will see another short wave and low pressure track east-southeast across the area, mainly aftn/eve.
The 00 UTC model runs have some good frontogenesis developing along a fairly sharp cold front.
Another disturbance and cold front move through the region on Tuesday, bringing another shot for light precipitation and gusty winds.
