622 PM CDT Mon Apr 14 2025 (Tonight through Tuesday night) Key Message: - Unseasonably warm today, cooler on Tuesday. A cold front is draped across northern and central Texas this afternoon, expected to move south over the area overnight before stalling in the southern portion of the CWA south of the San Antonio metro tomorrow. Cooler temperatures in upper 70s and 80s are forecast Tuesday with partly cloudy skies.
625 PM CDT Mon Apr 14 2025 Tonight and Tuesday: A cold front will bring a few light showers across the area but with a lack of substantial upper forcing and limited moisture, amounts will be light and many areas likely remain dry. Primary impacts will be on highs tomorrow-- about 10 degrees cooler than today, topping out in the 70s F.
1115 PM EDT Mon Apr 14 2025 A strong cold front will bring the chance for showers and isolated storms tonight.
Scattered convection ahead of incoming cold front will produce some strong wind gusts through daybreak. Discussion: Scattered convection continues over the far northern TN valley and southwest Virginia, and back into middle TN, just ahead of an incoming cold front. Otherwise, the cold front should move into the Appalachians by 7-8am or thereabouts.
857 PM PDT Mon Apr 14 2025 Low pressure will keep us cool and breezy this week.
121 AM EDT Tue Apr 15 2025 High pressure will hold off the Southeast coast, producing a warm southwest flow over our area. A cold front will push southeast through the region this morning, bringing gusty northwest winds by this afternoon.
- Cooler temperatures will return to the region today and tomorrow.
239 AM EDT Tue Apr 15 2025 A strong cold front will bring the chance for showers and isolated storms tonight.
1150 PM CDT Mon Apr 14 2025 (Rest of tonight and Tuesday) A cold front continues to slowly move southeast toward northern Alabama at this time. Lows tonight will eventually drop some behind the front into the low to mid 50s around daybreak on Tuesday. This should crater dewpoints into the lower to mid 20s in many areas (maybe a few upper teens as well).
1011 PM CDT Mon Apr 14 2025 The mid-evening sfc analysis indicates that our cold front extends near or just NW of the I-30 corridor of NE TX/SW AR, and into Cntrl AR to near LIT. Despite the presence of the front, the mid-evening moisture profile remains shallow and mostly confined to the lowest 6kft, but any convergence along the attendant H925-850 trough remains weak and given the absence of deeper moisture and forcing aloft, isolated -SHRA development has been hard to come by so far this evening. Also removed mention of slight chance pops across portions of Deep E TX shortly after daybreak Tuesday, with a decrease in low and elevated cigs expected through the day giving way to slightly cooler and less humid conditions. But over the next several hours conditions will begin to deteriorate with an incoming cold front.
1245 AM CDT Tue Apr 15 2025 A cold front is currently pushing through the Memphis to Texarkana area and will continue southeastward across our area overnight. /DL/ Tonight and Tuesday: A cold front will bring a few light showers across the area but with a lack of substantial upper forcing and limited moisture, amounts will be light and many areas likely remain dry. Primary impacts will be on highs tomorrow-- about 10 degrees cooler than today, topping out in the 70s F.
444 AM EDT Tue Apr 15 2025 An upper level trough of low pressure will move through the area today leading to clouds and a chance for showers.
111 AM EDT Tue Apr 15 2025 (Rest of today through Tuesday) High pressure will continue to move slowly eastward from the Florida Peninsula into the Western Atlantic waters.
328 AM EDT Tue Apr 15 2025 Showers and windy conditions are expected today with a trough of low pressure.
(Rest of tonight and Tuesday) A cold front continues to slowly move southeast toward northern Alabama at this time. Lows tonight will eventually drop some behind the front into the low to mid 50s around daybreak on Tuesday. This should crater dewpoints into the lower to mid 20s in many areas (maybe a few upper teens as well).
Quiet weather is forecasted for both today and tomorrow as high pressure and ridging dominates.
225 AM CDT Tue Apr 15 2025 Latest water vapor imagery shows an upper trough digging into the Mid Mississippi Valley, with a ridge building into the Desert Southwest. At the surface, a cold front was extending southwestward from it's parent low over New England through the TN Valley and into the Southern Plains. The trough is expected to quickly move eastward today, with the cold front sliding southward and through the local area by this afternoon. The remainder of the work week will be dry and fairly pleasant as high pressure settles in the wake of the cold front. Upper ridging will build eastward through the end of the week and strengthen over the weekend.
125 AM EDT Tue Apr 15 2025 - Cooler and windy on Tuesday.
Gusty northerly winds under a thermal trough continue tonight, sustaining steep seas in area waters. The thermal trough strengthens and northerly winds increase late tonight int Tuesday morning, with the strongest winds south of Cape Blanco.
259 AM CDT Tue Apr 15 2025 - Clearing today and staying cooler, then warming trend Weds/Thurs.
220 AM EDT Tue Apr 15 2025 A cold front will move across the area this evening. A secondary trough of low pressure will swing through the area on Tuesday. High pressure will build in midweek. A cold front will continue to make its way east and out of the forecast area this evening/early morning. It will be drier and cooler. Lows will range from the lower 40s northwest to the upper 40s southeast.
143 AM MDT Tue Apr 15 2025 KEY MESSAGES: * Warm and dry conditions are expected today with upper ridge moving through Montana.
141 AM MDT Tue Apr 15 2025 - High pressure will produce warm, dry weather today.
The overnight shift has had the pleasure of monitoring calm conditions across the region as high pressure is still in place. As of 430 AM EDT, temperatures were mostly in the lower 70s, but the real star was dew points in the low 60s. With this high in place, today will look a lot like yesterday with highs near 80, plenty of sunshine, and light breezes out of the east becoming variable. The combination of GOES-19 Water Vapor imagery, and surface observations show low pressure centered to the north of the Great Lakes with a lengthy cold front that extends from New York to Texas. Over the next couple of days, the parent low is going to lift to the northeast, and drag the cold front through the southeast toward the North Atlantic.
(Today and tonight) We will temporarily move away from the recent deep layer high pressure regime today as a short wave trough moves from the Mississippi Valley across the Southeast before moving east of the area tonight. This trough will help usher a cold front through the forecast area. It will be a cooler night behind the front will morning lows in the mid 40s north to lower 50s near the coast.
A fairly quiet and slightly warmer start to the day compared to yesterday.
357 AM EDT Tue Apr 15 2025 A cold front will finish crossing the region this morning.

Cooler temperatures in upper 70s and 80s are forecast Tuesday with partly cloudy skies.
1007 PM MDT Mon Apr 14 2025 - High pressure will produce warm, dry weather into midweek. It's a beautiful Spring day across eastern as high pressure is in full control of the weather. Lower valleys will likely top out in the low to mid 60s before the afternoon is up. The ridge will amplify further overnight and into the day Tuesday allowing for even warmer weather tomorrow where low 70s will be commonplace in the lower valleys with low to mid 60s across the high country.
1058 AM EDT Tue Apr 15 2025 Now that a cold front has pushed throug hthe region. Compact low pressure tracking from Ontario into Quebec will circulate increasing amounts of synoptic moisture over our region as well. While up to an inch of wet snow will be possible on elevated surfaces across the higher terrain, travel impacts are not expected. Additional snow showers will coat elevated surface below 1000 feet, while overnight amounts will range from 1 to 3 inches across the higher terrain of the Southern Tier to 4 to 7 inches across the Tug Hill plateau where a winter weather advisory remains in effect. Snowfall accumulations will be light with 1 to 2 inches across the higher terrain (S. The mid-level trough exits off into the Canadian Maritimes Wednesday night.
Early morning surface analysis had the cold front across our northwest most zones. Local radars were showing a rather narrow line of very light returns over our northwest along the cold front. Sprinkles to very light showers will remain possible early this morning until the cold front shifts far enough southeast of our CWA. A >1028mb high will build into our CWA from the west today in the wake of the cold front.
High pressure will allow dry conditions and above normal temperatures to persist through the end of the work week as our stretch of pleasant weather continues.
520 AM MDT Tue Apr 15 2025 - High pressure will produce warm, dry weather today.
609 AM CDT Tue Apr 15 2025 (Rest of tonight and Tuesday) A cold front continues to slowly move southeast toward northern Alabama at this time. Lows tonight will eventually drop some behind the front into the low to mid 50s around daybreak on Tuesday. This should crater dewpoints into the lower to mid 20s in many areas (maybe a few upper teens as well).
659 AM CDT Tue Apr 15 2025 (Today through Wednesday Night) Highs today will be a few degrees cooler, courtesy of a FROPA moving through Southeast Texas this morning.
625 AM CDT Tue Apr 15 2025 (Today through Wednesday) Cold front has entered northwest Alabama, and is forecast by models to push through the CWA this morning.
425 AM PDT Tue Apr 15 2025 Drier and warmer conditions will continue through today.
957 AM EDT Tue Apr 15 2025 Only minor changes to the forecast this morning which involved increasing forecast wind gusts for this afternoon as a cold front moves through the region. (Today and tonight) We will temporarily move away from the recent deep layer high pressure regime today as a short wave trough moves from the Mississippi Valley across the Southeast before moving east of the area tonight. This trough will help usher a cold front through the forecast area. It will be a cooler night behind the front will morning lows in the mid 40s north to lower 50s near the coast.
Quiet weather is forecasted for both today and tomorrow as high pressure and ridging dominates. Ridging is most pronounced on Wednesday, which will result in the warmest temperatures that afternoon.
(This afternoon through Wednesday) Cooler air and drier dew points are advecting into our Four-State area this morning with the cool front now well to our south. /24/ (Wednesday Night through Tuesday) Dry conditions will prevail through the remainder of the work week with upper ridging over the region.
Leaving behind clearing skies, but cooler temperatures. Scattered convection ahead of incoming cold front will produce some strong wind gusts through daybreak. Discussion: Scattered convection continues over the far northern TN valley and southwest Virginia, and back into middle TN, just ahead of an incoming cold front. Otherwise, the cold front should move into the Appalachians by 7-8am or thereabouts.
(Today through Wednesday Night) Highs today will be a few degrees cooler, courtesy of a FROPA moving through Southeast Texas this morning.
610 AM EDT Tue Apr 15 2025 - Much cooler today with light showers.
620 AM CDT Tue Apr 15 2025 (Today through Wednesday) A cold front has moved into the northern Hill Country and southern Edwards Plateau and will continue south into the I-35 corridor this morning, stalling just south of the U. High temperatures cooler today, ranging from the low to mid 80s across the Hill Country, I-35 corridor, and Coastal Plains, to upper 80s to lower 90s along the Rio Grande. Highs a couple of degrees warmer Wednesday across the Hill Country and I-35 corridor.
621 AM CDT Tue Apr 15 2025 Latest water vapor imagery shows an upper trough digging into the Mid Mississippi Valley, with a ridge building into the Desert Southwest. At the surface, a cold front was extending southwestward from it's parent low over New England through the TN Valley and into the Southern Plains. The trough is expected to quickly move eastward today, with the cold front sliding southward and through the local area by this afternoon. The remainder of the work week will be dry and fairly pleasant as high pressure settles in the wake of the cold front. Upper ridging will build eastward through the end of the week and strengthen over the weekend. Overnight lows tonight and on Wednesday night will be on the cooler side, as radiational cooling allows for temps to fall into the 40s.
The overall synoptic pattern of mid-level ridging will maintain dry and warm conditions overall.
Additionally, a trough will start to drop through the Intermountain West, placing our forecast area in a convergence zone. Rainfall amounts will generally be low, but will favor the higher terrain with occasional lightning possible.
313 AM PDT Tue Apr 15 2025 Drier and warmer conditions will continue through today.
A fairly quiet and slightly warmer start to the day compared to yesterday. Light and variable winds will increase through the day as cold front approaches the peninsula late tonight into Wednesday. Upper level ridge begins to build across the region helping to filter in drier and cooler air (at least for a night or two) over the state. Area of high pressure continues to build with moisture gradually increases towards the end of the period. Area pf high pressure over the waters for light winds today.
519 AM MDT Tue Apr 15 2025 - Warm conditions across the state today and Wednesday under high pressure. - Winter tries to reassert itself Wednesday night, as a cold front bring much colder temperatures and snow to most areas east of the Divide. Today and Wednesday will be marked by a return of much warmer temperatures as a high-amplitude ridge sweeps past. Then the bottom falls out from under temperatures as a late- season cold front races through Wednesday night. The approaching system brings along ample moisture into the region, which will get tapped by the cold front.
Warm and dry conditions will persist today under high pressure. By midweek, scattered rain showers and isolated thunderstorms are possible Wednesday afternoon ahead of a cold front.
212 AM PDT Tue Apr 15 2025 * Warmer weather continues through Wednesday with snowmelt resulting in streams running fast and cold.
Temperatures are in the upper 70s, nearing 80 degrees, dew points in the lower to mid 60s. This is weakening the area of high pressure across the region and bifurcating it into two cells. Day time highs will reach into the lower 80s with plenty of sunshine. High pressure is still stretched across the region, allowing for breezes to become light and variable. The decaying tail end of a cold front will clip the local waters Wednesday, but the only change in weather conditions will be breezes assuming a northerly direction.
Behind the front today, NNE winds will bring much lower humidity values and slightly cooler temps into the region. /20/ (Wednesday Night through Tuesday) Dry conditions will prevail through the remainder of the work week with upper ridging over the region.
629 AM EDT Tue Apr 15 2025 (Today and tonight) We will temporarily move away from the recent deep layer high pressure regime today as a short wave trough moves from the Mississippi Valley across the Southeast before moving east of the area tonight. This trough will help usher a cold front through the forecast area. It will be a cooler night behind the front will morning lows in the mid 40s north to lower 50s near the coast.
611 AM CDT Tue Apr 15 2025 - Clearing today and staying cooler, then warming trend Weds/Thurs.
- Wintry weather returns from north-to-south Wednesday night as a cold front pushes south through areas east of the Continental Divide.
146 PM MDT Tue Apr 15 2025 - High pressure will produce warm, dry weather today.
106 PM CDT Tue Apr 15 2025 (Today through Wednesday Night) Highs today will be a few degrees cooler, courtesy of a FROPA moving through Southeast Texas this morning.
1209 PM CDT Tue Apr 15 2025 (Today through Wednesday) A cold front has moved into the northern Hill Country and southern Edwards Plateau and will continue south into the I-35 corridor this morning, stalling just south of the U. High temperatures cooler today, ranging from the low to mid 80s across the Hill Country, I-35 corridor, and Coastal Plains, to upper 80s to lower 90s along the Rio Grande. Highs a couple of degrees warmer Wednesday across the Hill Country and I-35 corridor.
1218 PM CDT Tue Apr 15 2025 In the wake of the overnight cold front passage, there's an interesting observation to make regarding this air mass. While cooler than yesterday's air mass for sure (about 10 degree lower highs this afternoon), the frontal boundary itself was marked by a very minimal temperature difference. Early morning surface analysis had the cold front across our northwest most zones. Local radars were showing a rather narrow line of very light returns over our northwest along the cold front. Sprinkles to very light showers will remain possible early this morning until the cold front shifts far enough southeast of our CWA. A >1028mb high will build into our CWA from the west today in the wake of the cold front.
High pressure will build back in fairly quickly behind the front, providing a return to an easterly flow component with not only the sea breeze on Tuesday but through the rest of the short term forecast period.
Isolated cold spots may read a few degrees cooler if the boundary layer can decouple.
(Rest of Today and Tonight) In wake of a cold front that pushed through the Tennessee Valley last night, a cooler and drier air mass to the region has moved into the area. Otherwise, notably cooler conditions, with highs struggling to climb above the mid 60s in most locations despite the ample sunshine. After sunset, winds will quickly decouple as the pressure gradient decouples and lows will drop into the lower 40s in this cool/dry air mass under a clear sky.
/24/ (This afternoon through Wednesday) Cooler air and drier dew points are advecting into our Four-State area this morning with the cool front now well to our south. /24/ (Wednesday Night through Tuesday) Dry conditions will prevail through the remainder of the work week with upper ridging over the region.
327 PM EDT Tue Apr 15 2025 Showers drop in coverage and transition to snow north of I-80 and in the ridges tonight.
Today continues to look pleasant with the upper level ridge staying overhead, bringing us the warmest day of the week. Highs today will be in the low to mid 70s barring higher elevations in the mountains. This ridge begins to break down tomorrow.
310 PM EDT Tue Apr 15 2025 Very gusty winds and cooler temperatures are in store for today through Wednesday night.
248 PM MDT Tue Apr 15 2025 KEY MESSAGES: * Warm and dry conditions are expected today with an upper ridge moving through Montana. * Beginning Wednesday, an upper trough will bring cooler temperatures and chances for rain to the area mainly south of the Missouri River. WEATHER PATTERN OVERVIEW: The broad upper ridge moves across Montana today with mostly clear skies.
1200 PM CDT Tue Apr 15 2025 (Rest of Today and Tonight) In wake of a cold front that pushed through the Tennessee Valley last night, a cooler and drier air mass to the region has moved into the area. Otherwise, notably cooler conditions, with highs struggling to climb above the mid 60s in most locations despite the ample sunshine. After sunset, winds will quickly decouple as the pressure gradient decouples and lows will drop into the lower 40s in this cool/dry air mass under a clear sky.
1217 PM EDT Tue Apr 15 2025 - Much cooler today with light showers.
(This afternoon through Wednesday) Behind this morning's cloudy but rain-free frontal passage, an area of dry high pressure is advancing on the region.
High clouds are moving up from the south ahead of an upper low, but they are rather thin, and the perception is it will be sunny to mostly sunny today. The thermal trough strengthens and northerly winds increase this morning, with the strongest winds south of Cape Blanco.
1220 PM CDT Tue Apr 15 2025 (Today through Wednesday) Cold front over SE Arkansas this morning will continue moving SE reaching our area by 8ish AM today for northern areas and should be at the coast by 8pm.
Latest water vapor imagery shows upper trough axis over southeast CONUS is moving steadily eastward, and model data indicates that the trough will be off the east coast by early Wednesday with ridging, both surface and aloft, building over our local area through Wednesday night. Surface front has moved south across the area this morning and much drier and somewhat cooler air will be building into the region tonight through Wednesday night. Daytime highs on Wednesday will be in the low to mid 70s across the entire area (but with much lower dewpoints and less humidity). Overnight lows both tonight and Wednesday night will be in the 40s for all inland locations and in the low to mid 50s closer to and along the coast.
126 PM CDT Tue Apr 15 2025 Latest water vapor imagery shows an upper trough digging into the Mid Mississippi Valley, with a ridge building into the Desert Southwest. At the surface, a cold front was extending southwestward from it's parent low over New England through the TN Valley and into the Southern Plains. The trough is expected to quickly move eastward today, with the cold front sliding southward and through the local area by this afternoon. The remainder of the work week will be dry and fairly pleasant as high pressure settles in the wake of the cold front. Upper ridging will build eastward through the end of the week and strengthen over the weekend. Overnight lows tonight and on Wednesday night will be on the cooler side, as radiational cooling allows for temps to fall into the 40s.
1131 AM MDT Tue Apr 15 2025 - High pressure will produce warm, dry weather today.
As the high shifts off to the east late tonight into Wednesday, winds will turn to the southeast across the entire FA, getting a little gusty by mid to late Wednesday morning on through the afternoon.
430 PM EDT Tue Apr 15 2025 * Numerous SHRA and isolated TSRA accompany the passage of an upper level trough this afternoon. * Become windy and turning much cooler with rain showers changing to snow showers over the Laurel Highlands and Northwest Mountains this afternoon and continuing into Wednesday morning. * A light accumulation of 1 to 2 inches of snow is likely across the higher terrain near and to the West of Route 219. Mixing heights up to 10k feet are tapping robust bulk shear and low freezing levels to produce strong sfc wind gusts over 40 kts and pea sized hail.
In the wake of the overnight cold front passage, there's an interesting observation to make regarding this air mass. While cooler than yesterday's air mass for sure (about 10 degree lower highs this afternoon), the frontal boundary itself was marked by a very minimal temperature difference. Early morning surface analysis had the cold front across our northwest most zones. Local radars were showing a rather narrow line of very light returns over our northwest along the cold front. Sprinkles to very light showers will remain possible early this morning until the cold front shifts far enough southeast of our CWA. A >1028mb high will build into our CWA from the west today in the wake of the cold front.
314 PM EDT Tue Apr 15 2025 A passing light shower may accompany a cold front this afternoon through early this evening.
Look for highs in the low to mid 80s inland and the upper 70s along the immediate coast.
