(Today through Sunday) Key Message: - Seasonably warm Upper level ridging passes overhead this weekend.
As the low clouds move into the areas experiencing fog, we hope that conditions improve. The cold front is forecast to drop into the area this morning into the afternoon hours, bringing a lifting mechanism for some shower development today. (Tonight through Sunday night) Cooler and drier air will filter in Saturday night with dew points and temperatures dropping back into the 50s.
- Much warmer weather can be expected for Sunday, along with very small chances for late day severe t-storms. The cold front that passed yesterday morning continues to result in moist upslope easterly winds; and this will persist through tonight. A strong upper level trough will approach the high plains Sunday night.
155 AM EDT Sat Apr 26 2025 An area of low pressure will slide eastward across the Northern Middle Atlantic Saturday and push a cold front through the area by Saturday evening.
Cold front passage occurs this afternoon bringing an end to rain chances. A cold front is well upstream near the Mississippi River. Showers will clear out by early to mid afternoon as the cold front moves through the region. Some showers will linger through the afternoon and early evening near the higher terrain of the East Tennessee mountains as northwest flow aloft adds lift. Tonight, widespread dry weather returns! Clearing skies and northerly winds will allow for cooler temps with lows from the mid 40s to lower 50s in the Tennessee Valley.
High-Res short-range ensembles still placing Central California in the target zone as a the cold- core upper low traverses the area on Saturday.
(Today) A shallow cold front has pushed into southeast Oklahoma this morning bringing slightly drier air and northerly low level flow. High temperatures today will likely be capped by clouds and precipitation in the west, so highs may only reach the low 70s.
Enough ridging looks to remain in place to support continued dry and above normal to near record temps again on Saturday, with highs in the mid to upper 80s coastal where the sea breeze will shave a few degrees off of high temps, and the lower to mid 90s away from the coast and over the interior.
1239 AM CDT Sat Apr 26 2025 (Tonight through Saturday night) Upper level ridging across the Southern Plains looks to persist through the period. Low temperatures tonight and Saturday night are expected to be in the low to mid 70s, with high temperatures Saturday afternoon in the upper 80s to low 90s.
317 AM CDT Sat Apr 26 2025 - Spotty showers (20-30%) will be possible today with cooler temperatures.
141 AM EDT Sat Apr 26 2025 A cold front will cross the region tonight, allowing drier air to prevail as high pressure builds in.
A broken line of showers and thunderstorms developed out ahead of the trough this evening and continues to push east across the CWA this morning. At the surface, a cold front currently stretches from the central Great Lakes back through the mid Mississippi River Valley. High pressure will build in from the NE later Sunday. Not much cooler air expected behind the front.
Ridging aloft will increase its presence across the forecast area today. While this happens, high pressure to the northwest of the region will build into the forecast area. Thus, causing a weak cold front to move into the CWA. Ridging aloft will again increase across the Lower Mississippi River Valley through mid-week. This, while high pressure at the surface wedges itself into the forecast area from the east.
Widespread showers continue tonight around a low pressure system passing over central California, with Coos and Curry counties seeing less activity given the easterly flow pattern. Chances are still slight (~15%) at the highest, with updated guidance showing an expanded area for possible thunderstorms.
(Today through Sunday) This AM, satellite is indicating a large swath of low level moisture on the night fog product, left behind from the now exited to our E upper trough. The highest amounts were in the far W portions of C AL. While there are patches of fog across the NRN parts of the CWA, the lowest vsbys are in the far W toward the MS state line.
714 AM CDT Sat Apr 26 2025 Upper level heights will start to increase today as an upper ridge over the southern plains builds northeast. Lows will range from the low 60s inland to mid/upper 60s near the coast.
656 AM EDT Sat Apr 26 2025 (Today through Sunday) A pair of high pressure systems, one over the NE Gulf and another over the western Atlantic will keep things primarily dry this weekend. Low temps tonight will range from the lower 60s inland to around 70 close to the Atlantic coast.
627 AM CDT Sat Apr 26 2025 (Today through Sunday) Deep South Texas and the Rio Grande Valley will be under the direct influence of 500 mb high pressure, which will steadily build northeast out of neighboring Mexico during the period. Finally, elevated seas along the Lower Texas Coast will produce a Moderate Risk of rip currents at the local beaches.
Fairly quiet weather is expected today, especially in comparison to the past several days, as ridging builds aloft. Ridging aloft will increase its presence across the forecast area today. While this happens, high pressure to the northwest of the region will build into the forecast area. Thus, causing a weak cold front to move into the CWA. Ridging aloft will again increase across the Lower Mississippi River Valley through mid-week. This, while high pressure at the surface wedges itself into the forecast area from the east.
617 AM CDT Sat Apr 26 2025 - Spotty showers (20-30%) will be possible today with cooler temperatures.
The closed low that was offshore yesterday is now just off the southern California coast and will move onshore between Paso Robles and Santa Barbara (just north of LA) this morning. Morning radar and satellite imagery show clouds and precipitation rotating around this closed low with the orientation/movement from NE to SW across the CWA. The focus for precipitation this morning is from the Cascades southwestward, but as the low moves inland, highest odds for precipitation shift from the Cascades eastward this afternoon and evening. Instability remains on the low side, but CAPE of a few hundred J/KG could initiate a few stronger cells over portions of the east side this afternoon/evening. With the closed low moving away on Sunday, shower chances diminish across SE portions of the forecast area, while the remainder of the area dries out.
Upper level heights will start to increase today as an upper ridge over the southern plains builds northeast. Lows will range from the low 60s inland to mid/upper 60s near the coast.
It is all sponsored by area of high pressure that remains across the peninsula. This will allow afternoon highs to range from the low to mid 90s. Then, high pressure begins to weaken with temperatures peaking on Sunday.
High pressure remains in place through the weekend, with some cooling on Sunday. A weak frontal system will move into the area early in the week for light precipitation, with ridging rebounding in the second half of the week.
A cold front was located from just north of BNA-MEM and will arrive this afternoon. High pressure will build southeast from the western Great Lakes into the OH Valley tonight. This will continue to induce north-northeast flow advecting dew points in the lower 50s into the TN Valley. Overnight lows will thus be in the lower to middle 50s. The cold front that moves through today will orient itself more south to north across our eastern counties late Sunday into Sunday night as high pressure wedges west through the Carolinas into Georgia. This will divide dew points in the 50s east to the lower 60s west.
Water vapor imagery shows a fairly strong closed low moving onshore into California. This low will track eastward over the weekend with its center staying north of Arizona in Nevada and Utah.
This will keep temperatures at coastal locations in the 80s, while inland readings will still climb into the lower and middle 90s with a couple of more record highs possible. It is all sponsored by area of high pressure that remains across the peninsula. This will allow afternoon highs to range from the low to mid 90s. Then, high pressure begins to weaken with temperatures peaking on Sunday.
656 AM CDT Sat Apr 26 2025 (Today through Sunday) This AM, satellite is indicating a large swath of low level moisture on the night fog product, left behind from the now exited to our E upper trough. The highest amounts were in the far W portions of C AL. While there are patches of fog across the NRN parts of the CWA, the lowest vsbys are in the far W toward the MS state line.
616 AM CDT Sat Apr 26 2025 (Today through Sunday) Key Message: - Seasonably warm Upper level ridging passes overhead this weekend.
It will be cooler, with highs ranging from the upper 40s to mid to upper 50s and low 60s.
1227 PM CDT Sat Apr 26 2025 (Today through Sunday) Key Message: - Seasonably warm Upper level ridging passes overhead this weekend.
258 PM EDT Sat Apr 26 2025 A strong cold front pushes through this afternoon and evening, with scattered rain and even a few wet snow showers over the higher elevations tonight into Sunday morning.
(Tonight) A cold front was located in southern TN and will push south through the TN valley during the next couple of hours. Overnight lows should drop into the lower to middle 50s. The cold front that moves through today will orient itself more south to north across our eastern counties late Sunday into Sunday night as high pressure wedges west through the Carolinas into Georgia. This will divide dew points in the 50s east to the lower 60s west.
245 PM EDT Sat Apr 26 2025 Updated at 157 PM EDT Sat Apr 26 2025 - Upper level ridging over the Gulf will persist through Thurs resulting in very warm, mostly dry weather and below normal chances for afternoon/evening isolated showers and storms - Scattered strong to possibly severe storms likely on Thurs or Thurs night - Slightly cooler/drier weather likely Fri-Sat (This afternoon through Sunday) Fairly benign weather expected during the short term period with strong upper ridging over the Gulf and Florida panhandle.
High pressure remains in place through the weekend, with some cooling on Sunday. A weak frontal system will move into the area early in the week for light precipitation, with ridging rebounding in the second half of the week. This will likely put a damper to some of the high temperatures expected for today (more mid 60s instead of temps closer to 70).
242 PM EDT Sat Apr 26 2025 Residual storms possible Saturday before as a cold front pushes through. Western Greenbrier may have sub-freezing wind chill values. The timing of the lowest RH values may be during the calmer side of the winds but if the winds were to remain stronger for a longer period of time, there will be a fire weather concern along and east of the Blue Ridge.
1217 PM CDT Sat Apr 26 2025 (Today through Sunday) This AM, satellite is indicating a large swath of low level moisture on the night fog product, left behind from the now exited to our E upper trough. The highest amounts were in the far W portions of C AL. While there are patches of fog across the NRN parts of the CWA, the lowest vsbys are in the far W toward the MS state line.
This is mainly due to the Pacific upper low coming inland across northern california today and across northern Nevada tonight and Sunday. Showers and thunderstorms will increase, especially on the Idaho side, on Sunday as the upper low continues to move east.
Scattered convection may develop by or just before 00Z over portions of extreme NE TX/SE OK/SW AR, along a stationary front and ahead of the parent upper trough as it ejects ENE across Ern OK/Wrn AR, possibly affecting the TXK/ELD terminals.
Cold front exits the area this evening, with cooler and drier weather to follow through Sunday. Discussion: Surface obs indicate that a cold front has started to push into the area from the NW, as dewpoints in the central and southern TN Valley are in the lower 60s, with mid to upper 50s in the northern Plateau and SW VA.
1205 PM CDT Sat Apr 26 2025 - Spotty showers (20-30%) will be possible today with cooler temperatures.
With wx pattern remaining about as-is (mid/upper ridging from Mexico stretching nnewd across eastern TX, llvl onshore flow), one would expect wx to remain about status quo too.
247 PM EDT Sat Apr 26 2025 Residual storms possible Saturday before as a cold front pushes through. Western Greenbrier may have sub-freezing wind chill values. The timing of the lowest RH values may be during the calmer side of the winds but if the winds were to remain stronger for a longer period of time, there will be a fire weather concern along and east of the Blue Ridge.
(Rest of today through Sunday) A pair of high pressure systems, one over the NE Gulf and another over the western Atlantic will keep things primarily dry this weekend. Low temps tonight will range from the lower 60s inland to around 70 close to the Atlantic coast.
Southerly winds will aid in a continuation of unseasonably warm temperatures with overnight lows in the upper 60s to mid 70s and daytime highs in the upper 80s along the coastal areas to the low- mid 90s along and west of IH-69E. Moderate winds and elevated seas along the Lower Texas Coast will produce a Moderate Risk of rip currents at the local beaches.
1153 AM CDT Sat Apr 26 2025 (Today through Sunday) Deep South Texas and the Rio Grande Valley will be under the direct influence of 500 mb high pressure, which will steadily build northeast out of neighboring Mexico during the period. Finally, elevated seas along the Lower Texas Coast will produce a Moderate Risk of rip currents at the local beaches.
As the trough moves across the PacNW, this can strengthen the surface pressure gradients over the Cascade Gaps (KDLS/KRDM/KBDN/KYKM) thus inducing breezy to windy conditions.
- Windy and much warmer Sunday with strong south winds.
231 PM EDT Sat Apr 26 2025 A strong cold front pushes through this afternoon and evening, with scattered rain and even a few wet snow showers over the higher elevations tonight into Sunday morning.
Upper level heights will gradually increase slightly over our area through Sunday night as an upper ridge becomes more defined over the southern plains states and builds eastward across the central Gulf coast. Temperatures will continue to run above normal with overnight lows ranging from the low 60s inland to mid/upper 60s near the coast (and a few lower 70s possible for the barrier islands) both tonight and Sunday night.
Upper ridging becomes more dominant over the area tomorrow which should further suppress showers.
Despite several numerical models forecasting a sharp dry line to be draped somewhere over the central to eastern Panhandle tomorrow afternoon, along with increased upper level flow precluding an approaching closed low, most CAMs fail to initiate convection due to the presence of capping inversions.
(This evening through Sunday night) The upper level trough that brought yesterday's showers and thunderstorms is now east of the Appalachian Mountains. An upper level ridge has begun to build in behind it. Current obs indicate temperatures in the low to mid 80s which is right in-line with the forecast.
However, the potential for showers and storms will remain through the night as the frontal boundary near the Red River lifts back to the north as a warm front.
- Much warmer on Sunday with a few afternoon thunderstorms possible.
High pressure will hold through Sunday with the warm dry weather continuing and a couple of record highs once again possible away from the coast.
(This afternoon through Sunday) Fairly benign weather expected during the short term period with strong upper ridging over the Gulf and Florida panhandle.
731 PM EDT Sat Apr 26 2025 Residual storms possible Saturday before as a cold front pushes through. Western Greenbrier may have sub-freezing wind chill values. The timing of the lowest RH values may be during the calmer side of the winds but if the winds were to remain stronger for a longer period of time, there will be a fire weather concern along and east of the Blue Ridge.
619 PM CDT Sat Apr 26 2025 Upper level heights will gradually increase slightly over our area through Sunday night as an upper ridge becomes more defined over the southern plains states and builds eastward across the central Gulf coast.

957 PM EDT Sat Apr 26 2025 High pressure overnight through early parts of the work week, becoming unsettled again midweek. Skies continue to clear from the west this evening as high pressure builds into the area. Behind the departing cold front, a broad high pressure over the Great Lakes will extend south into the Ohio valley, and West Virginia for the rest of the weekend. This feature brings a drier airmass and cooler weather conditions Tonight and Sunday. Expect lows in the lower 40s across the lowlands, ranging into the lower 30s northeast mountains. Highs for Sunday will generally be in the 60s across the lowlands, ranging into the lower 50s northeast mountains.
New record high of 92 degrees set at TBW today, with warmth continuing on Sunday as highs once again reach the mid to upper 80s along the immediate coast and the lower to mid 90s elsewhere. High pressure will hold through Sunday with the warm dry weather continuing and a couple of record highs once again possible away from the coast.
A strong low pressure system making its way onshore into California will be heading north of us with a trajectory into the Great Basin this afternoon and evening.
Western Greenbrier may have sub-freezing wind chill values. The timing of the lowest RH values may be during the calmer side of the winds but if the winds were to remain stronger for a longer period of time, there will be a fire weather concern along and east of the Blue Ridge.
A dry weather system will bring cooler temperatures and elevated winds today and tomorrow.
954 PM CDT Sat Apr 26 2025 (This evening through Sunday night) The upper level trough that brought yesterday's showers and thunderstorms is now east of the Appalachian Mountains. An upper level ridge has begun to build in behind it. Current obs indicate temperatures in the low to mid 80s which is right in-line with the forecast.
Meanwhile, mid and upper level ridging are in place across the broader area. Surface ridging will remain in control of Keys weather through the overnight.
859 PM EDT Sat Apr 26 2025 As low pressure tracks across interior New England, a cold front will move through the area by this evening.
641 PM CDT Sat Apr 26 2025 (Tonight) A cold front was located in southern TN and will push south through the TN valley during the next couple of hours. Overnight lows should drop into the lower to middle 50s. The cold front that moves through today will orient itself more south to north across our eastern counties late Sunday into Sunday night as high pressure wedges west through the Carolinas into Georgia. This will divide dew points in the 50s east to the lower 60s west.
645 PM EDT Sat Apr 26 2025 (Rest of today through Sunday) A pair of high pressure systems, one over the NE Gulf and another over the western Atlantic will keep things primarily dry this weekend. Low temps tonight will range from the lower 60s inland to around 70 close to the Atlantic coast.
96 (This afternoon through Sunday) Fairly benign weather expected during the short term period with strong upper ridging over the Gulf and Florida panhandle.
716 PM EDT Sat Apr 26 2025 A cold front will cross the region overnight with drier and somewhat cooler air spreading over the area for Sunday. Key Message(s): - Any lingering showers dissipate quickly this evening as a cold front sweeps through the forecast area. A cold front sweeps through the region tonight ushering in cooler and drier air for Sunday. It may take time for the CAA to take over so low temperatures will likely vary with forecast temperatures ranging from the mid to upper 50s across the northern Midlands and the lower 60s elsewhere.
709 PM EDT Sat Apr 26 2025 High pressure overnight through early parts of the work week, becoming unsettled again midweek. Behind the departing cold front, a broad high pressure over the Great Lakes will extend south into the Ohio valley, and West Virginia for the rest of the weekend. This feature brings a drier airmass and cooler weather conditions Tonight and Sunday. Expect lows in the lower 40s across the lowlands, ranging into the lower 30s northeast mountains. Highs for Sunday will generally be in the 60s across the lowlands, ranging into the lower 50s northeast mountains.
342 AM EDT Sun Apr 27 2025 (Today through Monday) 500mb analysis shows ridging across Mexico that extends into the northern Gulf. A low pressure system is across southern NV. The low pressure system will move east and fill through Monday. The ridging across Mexico and the northern Gulf will build northeastward into the southeast states. This boundary will slowly move south through the day as high pressure builds in from the north. The high center currently across the western Great Lakes will move east through the day and then offshore the mid Atlantic coast by early Monday with a wedge building in from the NE. The highest pops should be across the southern quarter of the CWA.
There is a low chance this could be expanded northwestward into more portions of the area, however, this is where the highest confidence in any fog formation remains due to lingering moisture accompanied by mostly clear skies as well as calm winds early Sunday morning. Otherwise, low temperatures are forecast to reach the low to mid 50s.
1205 AM CDT Sun Apr 27 2025 - Much warmer on Sunday with a few afternoon thunderstorms possible.
1225 AM CDT Sun Apr 27 2025 Upper level heights will gradually increase slightly over our area through Sunday night as an upper ridge becomes more defined over the southern plains states and builds eastward across the central Gulf coast. Temperatures will continue to run above normal with overnight lows ranging from the low 60s inland to mid/upper 60s near the coast (and a few lower 70s possible for the barrier islands) both tonight and Sunday night.
This will be it for a while as we trend a little warmer and drier to unfold during Sunday and into the start the new week. Lows again tomorrow night will see mid to upper 60s as the ridging builds over Mexico and expands out over the western Gulf of America through the short term and early long.
316 AM EDT Sun Apr 27 2025 Dry and slightly cooler high pressure moves in today and Monday.
Thru the remainder of Sun and into Mon, amplifying H500 ridging over the Cntrl US wl promote drier and warmer condns, w/ temps set to climb to the mid to upper 80s at most sites on Mon.
351 AM EDT Sun Apr 27 2025 High pressure will keep dry conditions across the region through Monday.
- Cooler and wetter pattern anticipated this afternoon into Monday. A closed low pressure system currently centered over Nevada will move northeastward today, while a north-northeast wind shift is expected as a front drops southward from Canada. By tonight, the closed low will stall over southeast Idaho into Monday morning. 00" in the higher terrain.
High pressure remains overhead tonight and winds will be light to calm. Tonight will be the coldest night this week and could see areas bottom out in the upper 30s across the higher elevations.
