331 PM EST Sat Feb 22 2025 High pressure remains in control of the area through mid-week.
(This evening through Sunday Night) A coastal low pressure area will bring gusty coastal winds and periodic showers to southeast Texas through Sunday morning. We will see cloud cover decrease from west to east during the afternoon hours on sunday, so will see warmer max temps on Sunday with some afternoon sunshine.
The Key West version of winter weather continues this morning, but it does feel just a little warmer outside! 11 AM local time observations showed temperatures in the lower 70s, roughly 3 to 5 degrees warmer than this time yesterday. From synopsis, expansive high pressure will remain the dominant feature, maintaining fresh to occasionally strong northeast to easterly breezes through most of today. As the high moves offshore into the western North Atlantic, another weaker high will take its place across the Southeastern United States resulting in slackening breezes. An area of weak low pressure is expected to develop over the northwestern Gulf Sunday and Sunday night.
(Tonight) Mid level cloud cover associated with a passing upper trough axis continues to gradually move eastward over the mid TN Valley going into the afternoon hrs this Sat. Mostly clear skies should then prevail tonight as high pressure continues to gradually settle into the region from the west. Lows into early Sun may at least be a few degrees higher compared to the last few mornings, as temps fall more into the lower/mid 20s. With sfc winds becoming light, patchy freezing fog is possible late tonight in more of the fog prone sheltered/valley areas, although the prob is not very high attm.
(This evening through Sunday) A sharp short wave trough was currently moving eastward through southern New Mexico into Far West Texas this afternoon.
157 PM EST Sat Feb 22 2025 High pressure remains in control through the weekend. An expansive area of high pressure currently centered over the southeastern CONUS will remain in control of our weather through the weekend bringing fair weather. It will continue to be a little cooler than average. It won't be as cold as this morning with overnight lows mainly in the mid to upper 20s, except low 20s over the southern Poconos, NW NJ, and the cooler spots of interior southern NJ such as the Pine Barrens. It will remain dry however with temperatures a few degrees warmer than today.
1143 AM MST Sat Feb 22 2025 - Gusty winds up to 50 mph will develop tonight over the higher east slopes of the Front Range.
(Today through Sunday) High pressure over the region will weaken a bit Today allowing increased cloud cover. Things clear out Sat night as another high pressure ridge builds in from MS/AL becoming centered over NW GA buy Sun morning. Temps this morning should bottom out in the lower to mid 20s across the area with some upper 20s across southern central GA.
Current synoptic situation depicts a high pressure system over the southwestern United States. By tonight, a strong upper jet will impinge upon the ridge and suppress it southward. Winds will also develop out of the southwest with gusts to 25 mph, especially over northern Nevada and the higher terrain in the central parts.
/33/ (Saturday through Sunday) An upper-level trough swinging east across Oklahoma and Arkansas has allowed for weak echoes to be observed across much of east and northeast Texas and north Louisiana this morning. Could see a few showers across portions of Deep East Texas and north Louisiana later today as the atmosphere begins to saturate in the lower-levels. Upper-level flow to become southwest ahead of a trough that will swing east across the region overnight. Temperatures are forecast to fall into the 30s across the region overnight with below freezing temperatures expected across mainly south Arkansas, northeast Texas, and southeast Oklahoma. Based on model trends over the past several runs, the chance of wintry precip will be minimal due to the highest pop values remaining south of the freezing line.
Clear skies and light winds will lead to favorable radiational cooling with another cold overnight, albeit, warmer than previous nights. Cold front with widespread rain possible Wed night into Thu.
359 PM EST Sat Feb 22 2025 High pressure will build across the region this evening through tonight.
(Rest of today and tonight) Compressional warming from downslope winds this afternoon will foster high temperatures in the 50s for most locations, and into the low 60s across western Oklahoma.
Temperatures will be largely unchanged or even a bit warmer than today and winds will not be particularly gusty.
(This evening through Sunday night) As an upper trough passes south of our region, southerly flow is left in it's wake. Warm air advection continues for the next couple of days and high pressure prevails at the surface.
1003 AM EST Sat Feb 22 2025 High pressure over central NC this morning will shift offshore tonight.
That tries to thin out a bit Sunday as warmer 850mb air works in. Highs Sunday in the low-mid 30s.
With temperatures near I-20 and northward falling to near and below freezing overnight, automated, blended guidance has intermittently returned the idea of freezing rain in some areas. This appears to be in error; the colder guidance delays or suppresses clouds and rain and the wetter guidance is warmer/cloudier earlier. The spurious freezing rain chances have thus continued to be eliminated from the forecast. To be clear, freezing rain is NOT expected on Sunday. Rain ends later Sunday with some areas around the highway 84 corridor likely seeing 1-1. Another seasonably cool night is then on tap Sunday night with temperatures near freezing north of I-20 and in the mid 30s F to near 40 F to the south.
1131 AM CST Sat Feb 22 2025 A few showers have developed this morning across the region as an H5 upper trough moves east across the Tennessee and mid MS River Valley. This is just enough to help produce lightning with the highest tops that can be produced Sunday. The chance of lightning has moved up but it remains in the isolated category with the highest percentage at 20% mainly along west and south of a line from interstate 55 to Lake Pontchartrain then east along the coast.
Meanwhile, a weak inverted trough off the northeast FL coast will shift off to the NE this evening and this will allow a weak cool front to slide southward through the region tonight and bring a brief round of drier air as PWATs fall below an inch overnight.

1239 PM EST Sat Feb 22 2025 High pressure over central NC this morning will shift offshore tonight.
(Rest of Today) Mid level cloud cover associated with a fast moving upper trough axis continues to translate eastward over much of the region this late Sat morning. These clouds should eventually move east of the of the mid TN Valley this afternoon as the upper trough exits the region. Otherwise, high pressure at the sfc will also gradually move into the region later today, with continued dry wx as highs trend predom in the mid/perhaps upper 40s for most spots.
1211 PM EST Sat Feb 22 2025 High pressure remains in control through the weekend.

1226 AM EST Sun Feb 23 2025 A ridge continues to build from the Tennessee Valley and central Appalachians through Sunday.
Given the ongoing/progged track of the upper low across central Texas, most precipitation should remain south of the forecast area this morning. With temperatures expected to be near/just below freezing across southeastern Oklahoma towards sunrise, a brief window for freezing drizzle may also emerge.
118 AM EST Sun Feb 23 2025 High pressure remains in control of the area through mid-week.
At the surface, our forecast area will remain under the influence of a large ridge of high pressure, which will provide calm winds and conditions optimal for radiational cooling given clear skies and dewpoints in the upper teens-lower 20s. Thus, we have indicated lows in the 20-25F range for most of the region, with development of patchy freezing fog possible during the early morning hours in sheltered valleys and near large bodies of water.
Another dry and slightly warmer day is expected with highs reaching well into the 40s to low 50s in the south. WAA in the lower levels will also allow temperatures to rise further into the 40s and even lower 50s in the south.

312 AM EST Sun Feb 23 2025 High pressure will continue to impact the area today before shifting east tonight.
High pressure over the Tennessee Valley continues to be the dominate feature in the atmosphere and will bring mostly clear skies with no chances for precipitation. As the high center shifts eastward into the Carolinas, light southerly winds return and bring some warm air advection with highs today approaching the mid to upper 40s (still a little on the cool side compared to normal). Lows tonight under clear skies are expected to drop into the upper 20s to lower 30s, which is also slightly cooler than average.
1203 AM CST Sun Feb 23 2025 (This evening through Sunday Night) A coastal low pressure area will bring gusty coastal winds and periodic showers to southeast Texas through Sunday morning.

Rainfall will end from west to east Sunday with the low moving east of the area.
Meanwhile, deep layered moisture is rather high as a weak mid and upper level trough migrates eastward through the eastern United States. Despite the moisture, surface dew points are unimpressive in the lower 60s. Short Term Update - Winds will continue to slacken out of the east northeast as the high pushes further east southeastwards and continues to disintegrate. As a result, expect overnight lows to range in the upper 60s with dew points holding in the lower 60s.

520 AM CST Sun Feb 23 2025 (Today through Monday) A 500mb trough swings through Texas into Monday, kicking the coastal low further east across the Gulf and bringing much drier air into Deep South Texas. Light winds and clearing skies tonight will promote efficient radiational cooling, allowing temperatures to free fall after dark back into the low to mid 40s. A cooler day in the 60s is expected on the island with life- threatening rip currents still expected in the chilly surf.
Bascially, south shore areas will have the highest probability out of the entire CWA and isolated lightning is not out of the question.
This ridge is expected to move over southern Arizona by Monday morning, with associated height rises and warmer low-mid level temperatures arriving with it. Into mid-week, this ridge will flatten with flow aloft becoming generally zonal.
Meanwhile an upper level trough currently across west Texas is shifting eastward.
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.

Rain chances increase from the west ahead of this low this evening, overspreading the local area after midnight tonight into Monday, with the higher rain chances south of the Interstate 10 corridor of NE FL and decreasing rain chances northward across SE GA. Despite the increased cloudiness today, still expected near to above normal temperatures with mid level warm air advection pattern under SW winds aloft ahead of the approach low with highs in the low 60s across inland SE GA to the low 70s across our north-central FL zones.
Dry conditions will prevail through at least midweek as a ridge of high pressure dominates. Chances are north of Kern County along the Highway 99 corridor with the highest probabilities at 30 percent from Kingsburg to Traver to Goshen and west to around Hanford. An upper ridge over the region will maintain dry conditions and bring further warming today into Monday. An upper trough is expected to move over the Pacific Northwest on Monday night causing some brief cooling.
- Scattered rain and freezing rain is expected late tonight into Monday evening. While it will mostly be rain, the overnight passage could result in freezing rain mainly along and north of Hwy 2 from late tonight into Monday morning.
A quick moving system clipping the northern tier of the Silver state Sunday afternoon into Monday will be the only bug in the forecast this week as upper ridging brings a Springtime preview as near record high temperatures with quiet conditions move in for the week ahead.
Thinking with increasing winds this morning and the high clouds quickly moving in, the fog will not last more than another couple of hours.
