The cold front has yet to reach some portions of northern West Virginia this morning, keeping temperatures in the low-50s.
- Below freezing overnight temperatures are forecast for tonight across the Panhandles. (This evening through Monday night) Northerly flow prevails over the Panhandles according to the latest H500 RAP analysis as the trough associated with the low pressure system that brought winter weather to the region exits to the east. Given temperatures only reaching the 50s today and with clear skies tonight, temperatures should once again drop down below freezing for overnight lows. Some locations may once again drop down to near freezing on Monday night as we will have good radiational cooling due to clear skies and light winds.
228 PM CDT Sun Apr 6 2025 - Late season freezing temperatures are expected in some locations tonight and all locations Monday night. - Cold front moves through by daybreak Monday with a few clouds.
417 PM EDT Sun Apr 6 2025 One last wave of low pressure will bring precipitation to the Ohio Valley this evening. High pressure briefly builds in late tonight and early Monday, before a cold front moves through the area Monday afternoon.
1216 PM CDT Sun Apr 6 2025 - Near and below freezing temperatures set up early this morning mainly along and north of I-70.
(Rest of today through Monday) Latest model guidance and satellite analyses show a large trough/low complex migrating across the C CONUS with an associates sfc frontal boundary moving into the SE states. Meanwhile, SoFlo remains under the influence of the western periphery of a deep high pressure system centered over the west Atlantic. Higher dew points will translate in warmer conditions with afternoon highs climbing into the low-mid 90s over interior areas, and mid-upper 80s near the coasts.
118 PM MST Sun Apr 6 2025 Ridging aloft entering the area will drive temperatures up well above normal this week starting Monday.
A sunny day with expected highs in the upper 70s will give way to clouds and slightly cooler temperatures by Monday.
Updated at 227 PM CDT Sun Apr 6 2025 - Freeze Warning is in effect tonight into tomorrow morning - Mild and dry conditions are expected this coming work week (Rest of today and tonight) The mid-level trough axis continues to progress across the FA into this evening and expect gradual clearing to occur behind this axis.
High clouds will continue to spread across the region this morning as a Pacific cold front moves into southeast Oregon late tonight.
Updated at 213 PM CDT Sun Apr 6 2025 - Near freezing morning temperatures and below-normal afternoon temperatures on Monday.
Light to occasional moderate rain chances will continue through the period with slightly cooler temperatures Monday. While no significant impacts are expected, upper level divergence associated with the right entrance region of a ~130kt jet and the combination of vort lobes translating through upper troughing will promote precipitation chances continuing tonight and into Monday, though rain chances will generally be best in counties directly along the Appalachian mountains tomorrow.
1258 PM MDT Sun Apr 6 2025 KEY MESSAGES: - Cold front passage on Monday will bring breezy winds and increased clouds/showers.
Troughing /cyclonic flow aloft/ over the central CONUS will be supplanted by an upper level ridge progressing eastward across the Rockies and High Plains Mon-Tue.
1051 AM PDT Sun Apr 6 2025 High pressure will deliver warmer temperatures for Sunday in the mid 60s to mid 70s.
Temperatures will dip near freezing Sunday night. Areas across north-central Texas will dip near to below freezing, primarily along and west of US-281. Even for locations that remain above freezing, temperatures should still drop into the mid-30s. With high pressure building into the region and dry air funneling in from the central Plains, clear skies and light northwesterly winds will allow temperatures to warm considerably Monday afternoon, with highs in the 60s expected.
- A much colder air mass arrives behind a cold frontal passage this evening, and lingers until mid-week.
227 PM EDT Sun Apr 6 2025 - Cooler and breezy with rain and snow showers Monday.
639 PM CDT Sun Apr 6 2025 - Cool tonight with lows near freezing. At the surface, high pressure has built in over Kansas and driven periods of breezy north winds over the forecast area so far today. With little to no cloud coverage anticipated alongside these light winds, radiational cooling is expected to result in temperatures near to below freezing tonight.
938 PM EDT Sun Apr 6 2025 One last wave of low pressure will bring precipitation to the Ohio Valley this evening. High pressure briefly builds in late tonight and early Monday, before a cold front moves through the area Monday afternoon.
Dry conditions will also continue through the end of the week thanks to the ridge of high pressure building over the Western US.
712 PM EDT Sun Apr 6 2025 - Brief Burst of Snow Monday Morning - Rain/Snow Chances Midweek - Brief Burst of Snow Monday Morning A quick moving cold front will swing through Monday morning.
Today's late afternoon seabreeze collision even produced some light low topped showers over the Lake Wales Ridge into this evening. Another warm and humid night expected locally as the persistant upper longwave trough from Hudson Bay down through the Plains states and into Mexico has started to slowly move eastward pushing the complex system storm system through the North Gulf Coast and the Deep South tonight.
622 PM CDT Sun Apr 6 2025 Updated at 543 PM CDT Sun Apr 6 2025 - Freeze Warning is in effect tonight into tomorrow morning - Mild and dry conditions are expected this coming work week (Rest of today and tonight) The mid-level trough axis continues to progress across the FA into this evening and expect gradual clearing to occur behind this axis.

244 PM PDT Sun Apr 6 2025 High pressure will deliver warmer temperatures for Sunday in the mid 60s to mid 70s.
506 PM CDT Sun Apr 6 2025 (Tonight through Monday night) A rather potent cold front for early April has kept temperatures in the low 60s for most locations, with MFE nudging into the mid 60s.
353 PM PDT Sun Apr 6 2025 High pressure will deliver warmer temperatures for Sunday in the mid 60s to mid 70s.
611 PM CDT Sun Apr 6 2025 - Below freezing overnight temperatures are forecast for tonight across the Panhandles. (This evening through Monday night) Northerly flow prevails over the Panhandles according to the latest H500 RAP analysis as the trough associated with the low pressure system that brought winter weather to the region exits to the east. Given temperatures only reaching the 50s today and with clear skies tonight, temperatures should once again drop down below freezing for overnight lows. Some locations may once again drop down to near freezing on Monday night as we will have good radiational cooling due to clear skies and light winds.
550 PM CDT Sun Apr 6 2025 (This evening through Monday Night) Main story this short term period is the chilly weather expected as breezy northwesterly winds usher in cooler than normal temperatures. Skies are beginning to clear out along and south of I-10, so temperatures there will be getting into the low 60s.
741 PM EDT Sun Apr 6 2025 (Rest of today through Monday) Latest model guidance and satellite analyses show a large trough/low complex migrating across the C CONUS with an associates sfc frontal boundary moving into the SE states. Meanwhile, SoFlo remains under the influence of the western periphery of a deep high pressure system centered over the west Atlantic. Higher dew points will translate in warmer conditions with afternoon highs climbing into the low-mid 90s over interior areas, and mid-upper 80s near the coasts.
903 PM CDT Sun Apr 6 2025 (This evening through Monday Night) A dreary and cooler day continues this evening, accompanied by occasional light drizzle with these low cloud decks. Luckily, the perpetual trough that has been over the Great Plains will finally begin to push eastward tonight. Skies will remain clear on Monday night, contributing to a cooler night for the Ark-La-Tx.
931 PM EDT Sun Apr 6 2025 - Brief Burst of Snow Monday Morning - Rain/Snow Chances Midweek No changes to the going forecast at this time but it should be noted that the new 00Z HRRR has backed off considerably on tomorrow morning's quick snow burst with the cold frontal passage. - Brief Burst of Snow Monday Morning A quick moving cold front will swing through Monday morning.
741 PM EDT Sun Apr 6 2025 - Cooler and breezy with rain and snow showers Monday.
632 PM CDT Sun Apr 6 2025 (Tonight through Monday night) A midlevel trough will continue to move east across and north of the area tonight through Monday night. As the trough axis moves to the east, the pressure gradient will relax, diminishing our winds to a more light to moderate flow over land.
Thicker cumulus has been settling in and showers have been moving in today along a cold front. Since it was a warmer morning due to extra cloud cover, highs will still be above normal later this afternoon. With that, ridges will have stronger southerly/southwesterly flow tonight and continuing into tomorrow.
As a low pressure system tracks to our southeast, precipitation will likely be ongoing late this evening into early Monday morning. Some Hi-Res model soundings depict a sleet sounding (warm nose near 800mb) with cooler temperatures between 850mb to 875mb between 10pm to 2am tonight. With surface temperatures and dew points staying above freezing, hazardous impacts impacts will likely remain low. The highest amount will likely be in northern Jefferson County PA or Forest County, where cooler conditions reside; this region may see up to an inch of snow.
751 PM EDT Sun Apr 6 2025 One last wave of low pressure will bring precipitation to the Ohio Valley this evening. High pressure briefly builds in late tonight and early Monday, before a cold front moves through the area Monday afternoon.
Cooler weather is on the way. Temperatures behind this cold front will be much cooler than what we have been experiencing. Highs today will range from the lower 50s NW to middle to upper 60s on the plateau. Overnight lows will be in the lower to middle 40s area wide. (Monday Night through next Sunday) High pressure builds in and temperatures will "stay steady and slightly warm" through the work week.
Meanwhile, amplified troughing pressing into the eastern United States and Gulf will displace eastward the mid to upper level ridge currently located across Florida and the Bahamas. Even so, deep layered ridging will cling to control of our area with precipitable water remaining near seasonal norms, limited CAPE, and weak inhibition. Expect overnight lows to range in the upper 70s with dew points broadly in the lower 70s. An Atlantic surface pressure ridge stretches westward across South Florida and the Straits and well into the Gulf.
Northerly flow is currently in place over our region between a large upper low near Hudson Bay and 570DM mid level ridging building into the Northern Rockies. The main result will be cooler temperatures while we remain under northerly flow (a bit below average for early April) before ridging slides east through midweek. A mid level wave rotates through the region on the back side of this ridging bringing light precipitation (less than 20% chance for 0.
412 PM CDT Sun Apr 6 2025 Updated at 411 PM CDT Sun Apr 6 2025 - Near freezing morning temperatures and below-normal afternoon temperatures on Monday.
Aside from this, clouds should keep temperatures mild, even with the cooler air filtering in. KNAPP (This evening through Monday Night) A dreary and cooler day continues this evening, accompanied by occasional light drizzle with these low cloud decks. Luckily, the perpetual trough that has been over the Great Plains will finally begin to push eastward tonight. Skies will remain clear on Monday night, contributing to a cooler night for the Ark-La-Tx.
Ridging aloft entering the area will drive temperatures up well above normal this week starting Monday.
High pressure will bring warmer than normal, dry conditions most of Monday.
Freezing temperatures are expected west of I-35 with widespread frost areawide. /NEW/ /Through Monday Night/ The trough that brought our inclement weather conditions over the weekend will continue shifting eastward through the rest of the night. The latest guidance did slide the freezing line slightly to the east, therefore minor modifications will be made to the current Freeze Warning.
In the upper levels, a potent trough will dig into the southeastern US today, pulling a cold front across the central Gulf.
1201 AM CDT Mon Apr 7 2025 (This evening through Monday Night) Main story this short term period is the chilly weather expected as breezy northwesterly winds usher in cooler than normal temperatures. Skies are beginning to clear out along and south of I-10, so temperatures there will be getting into the low 60s.
- The week ahead looks quiet for our area weather-wise, with temperatures much warmer overall and dry conditions. (Today and tonight) We have a chilly start to the day with temperatures around freezing across west central Texas. The 850mb thermal ridge should strengthen from the west, which should result in high temperatures in the upper 60s to around 70 this afternoon.
1211 AM CDT Mon Apr 7 2025 - Below freezing overnight temperatures are forecast for tonight across the Panhandles. (This evening through Monday night) Northerly flow prevails over the Panhandles according to the latest H500 RAP analysis as the trough associated with the low pressure system that brought winter weather to the region exits to the east. Given temperatures only reaching the 50s today and with clear skies tonight, temperatures should once again drop down below freezing for overnight lows. Some locations may once again drop down to near freezing on Monday night as we will have good radiational cooling due to clear skies and light winds.
The convection is relatively shallow, as 50 dbZ echoes are struggling to reach the freezing level. Skies should clear by sunset or shortly thereafter, as much cooler and drier air moves into the area, with mostly clear/sunny skies for the rest of the overnight hours and on Tuesday. Overnight lows will be in the lower and middle 40s across much of the area. Areas immediately downwind of Lake Pontchartrain might remain in the lower 50s, and a few of the normally colder locations could briefly touch the upper 30s if winds go calm just before sunrise. Highs Tuesday should be in the lower 70s for most of the area, with guidance in pretty good agreement.
1229 AM CDT Mon Apr 7 2025 - Temperatures fall near or below freezing Monday and Tuesday mornings. A positively tilted, longwave trough extends from the Mid- Mississippi Valley into the Southern Plains this afternoon. Light winds and clear skies within the trough axis will allow for good radiational cooling, but low-level winds increase from the southwest behind this feature and ahead of a southward advancing cold front. Uncertainty remains in how quickly temperatures will drop and the degree of mixing within the boundary layer, but HREF and NBM probabilities show a 40-80% chance of temperatures at or below freezing for a few hours overnight. The aforementioned cold front pushes south through the area during the day on Monday.
- Freezing temperatures are expected west of I-35 tonight with widespread frost areawide. Light winds and clear skies will allow temperatures to drop to or just below freezing across parts of the region, especially west of I-35. Low level winds will become southerly Monday night and overnight lows will be 5-10 degrees warmer with no freezing concerns. Southerly winds will increase to 10 to 15 mph on Tuesday with sunny skies continuing and temperatures climbing back into the low to mid 70s which is near normal for this time of year.
Dry conditions will prevail as well thanks to the ridge of high pressure building over the Western US.
Min temps reflect the skycover grids, with the cooler spots located where expected clearing will be across southern IN, with low 30s and patchy frost possible. Upper trough axis and secondary cold frontal boundary will push through the region early Monday night. Lows Tuesday night will drop back into the lower 30s, with a possible light freeze, especially in the Bluegrass region.
Another strong cold front will bring rain and snow late today and tonight. This wave will at first eject the lingering moisture from the weekend, but will also drag a strong cold front through the region late this afternoon and evening. Precipitation associated with the cold front will be behind it in the strong cold advection.
Springlike temperatures continue - cooler Monday and near average Tuesday.
1142 PM CDT Sun Apr 6 2025 - Late season freezing temperatures are expected in some locations tonight and all locations Monday night. - Cold front moves through by daybreak Monday with a few clouds.
Clear skies with the light winds will allow temperatures to fall into the 30s with the exception of the Canadian River Valley and areas off the Caprock that may remain in the low 40s. Much warmer overnight temperatures, in the mid 40s across the FA, expected Tuesday night as H85 temperatures stay warm and winds stay closer to 10 mph allowing for some mixing.
333 AM EDT Mon Apr 7 2025 - Brief period of light snow this morning possible, chilly - Mid week mixed rain/snow - Brief period of light snow this morning possible, chilly Low pressure moving across northern Lower will pull a cold front south across the region today, ushering in another round of winter weather.
239 AM EDT Mon Apr 7 2025 A cold front will slowly progress east across the area through tonight. A much colder airmass arrives Tuesday, and overnight lows below freezing are likely by the middle of the week.
1202 AM CDT Mon Apr 7 2025 Updated at 1201 AM CDT Mon Apr 7 2025 - Near freezing morning temperatures and below-normal afternoon temperatures on Monday. (This afternoon through Monday night) WV imagery this afternoon shows the upper trough directly over West Texas and Southeast New Mexico. However, northwest winds are forecast to back to southwest, ending CAA and keeping temperatures a little warmer than they otherwise would be. Monday, flow aloft will be meridional in the wake of the exiting trough, and thicknesses will increase substantially under sunny skies.
(Today through Tuesday) Deep South Texas and the Rio Grande Valley, initially under the influence of a zonal mid-level flow, will increasingly be dominated by 500 mb high pressure that will build over the northwest coast of Mexico.
A rather nebulous forcing regime currently exists across the region, with an upper ridge establishing across the Intermountain West. Under mostly clear skies with light winds, efficient radiational cooling is beginning to foster sub-freezing early morning temperatures (and wind chills) for many areas.
A break in the low-lvl cloud cover was evident over S/Ern KS. As the clearing trend continues S/Ewrd into N/Wrn and Nrn AR, frost potential should incrs as temps fall below or to near freezing. This wl promote settled wx locally, w/ cooler and more seasonable temps over the FA, and no rain chances to mention.
1240 AM CDT Mon Apr 7 2025 (This evening through Tuesday) Trailing H500 trough across the Southern Plains will continue to push east across the state from tonight through Monday morning. At the sfc, ridging in place to the NW will shift southeastward into the state. Across these areas the coldest temperatures are expected, with some spots possibly falling below freezing Monday morning. Below normal temperatures will persist across the area through Tuesday as steep N/NW flow at the mid-levels will be seen across much of the middle of the country in the wake of a much stronger Great Lakes cyclone. This could provide another period of near-freezing temperatures and possible frost development Tuesday morning.
Expect slightly warmer temps each day with beautiful weather all week.
1215 AM CDT Mon Apr 7 2025 (Tonight through Monday night) A rather potent cold front for early April has kept temperatures in the low 60s for most locations, with MFE nudging into the mid 60s.
1109 PM CDT Sun Apr 6 2025 (Tonight through Monday night) A midlevel trough will continue to move east across and north of the area tonight through Monday night. As the trough axis moves to the east, the pressure gradient will relax, diminishing our winds to a more light to moderate flow over land.
Upper trough axis is sliding across the forecast area this evening. High temps today were already nearly 20 degrees below average for this time of year, so with a good head start overnight lows will drop to near or below freezing over much of the forecast area by Monday morning. Clearing skies and light winds are on tap for the area later tonight as high pressure builds into the region. This will allow temperatures to fall to near freezing or below freezing as we move into early Monday.
Low confidence in any widespread fog development this morning as the low level moisture isn't really there to support it.
High pressure moving through will cause light winds and mostly clear skies for much of the Northland and we expect nearly ideal radiational cooling.
High pressure builds across Arizona this week, leading to well above-normal temperatures and dry conditions. Heights continue to rise as high pressure builds into Arizona from the west. Warmer temperatures and dry conditions ensue as a result. High pressure begins its push eastward and into the Desert Southwest through much of this week with dry conditions expected. This will bring in much warmer air with increasing temperatures each day.
- This week will be quiet for our area weather-wise, with overall temperatures much warmer and dry conditions. (Today and tonight) We have a chilly start to the day with temperatures around freezing across west central Texas. The 850mb thermal ridge should strengthen from the west, which should result in high temperatures in the upper 60s to around 70 this afternoon.
This includes expected freezing temperatures the coldest night, tonight, with a Freeze Watch now upgraded to a Freeze Warning. Finally we're seeing the end to endless rain as drier/colder air settles in with the arrival of high pressure. The heart of the cold comes tonight, when freezing temperatures are forecast at some location in every one of our 58 counties.
Troughing /cyclonic flow aloft/ over the central CONUS will be supplanted by an upper level ridge progressing eastward across the Rockies and High Plains Mon-Tue. will rapidly erode/undercut the central CONUS ridge late Tue-Tue night. as the Tri-State area finds itself situated between an amplifying western CONUS ridge and an amplifying eastern CONUS trough. Long range guidance suggests that the aforementioned ridge will shift eastward across the central CONUS this weekend. as an upper level trough amplifies along the Pacific Coast and Intermountain West.
Another strong cold front will bring rain and snow late today and tonight. This wave will at first eject the lingering wintry mix south and east of Pittsburgh this morning, and will also drag a strong cold front through the region late this afternoon and evening. Precipitation associated with the cold front will be behind it in the strong cold advection.
The coldest areas will be over the southern Edwards Plateau and Hill Country where some locations, such as low lying areas along rivers, may see brief freezing temperatures or a light freeze before sunrise. Lows will be warmer tonight into Tuesday with no freezing concerns. High pressure moves east off the coast for Tuesday bringing back southerly flow to the area. This will allow for warmer highs on Tuesday back into the 70s and 80s.
