331 PM EST Sun Nov 9 2025 Rain showers are moving through the region this evening ahead of a cold front. Cooler temperatures settle in overnight behind the front allowing rain showers to transition to snow.
1033 AM MST Sun Nov 9 2025 - Cooler than normal temperatures are expected for today, with breezy northerly winds on our eastern plains.
The major point of concern/feature frigid cold front, the strongest/reinforcing portion of which has already managed to clear our area of responsibility, and now lingers off the Gulf coast.
Upper ridge will start to nose into the Plains on Monday, with winds shifting back to the south and warm air advection starting up. Warming trend will continue through much of the week with northwesterly flow aloft to ridging eventually transitioning to southwesterly flow by the end of the week. Still a lot of differences in how the trough over the western CONUS comes east into the weekend, with some solutions bringing out a closed low and others more open and progressive.
What can be said with confidence is that any precipitation today will be in the form of light snow/flurries due to the cold airmass overhead and max temperatures sub- freezing this afternoon.
The heart of the giant long wave cyclone makes mid Ohio River Valley passage late tonight into Monday. The strong PVA rotating across the area with the mean trof axis may even squeeze out a few flurries or light snow showers while this occurs, with best chances north and east closest to the center of the cyclone; would not be shocked to see a dusting on grassy surfaces, but no significant accumulations are expected. The parent cyclone responsible for the polar plunge of air makes its Ohio Valley passage late tonight-Monday. Restricted CIGS are most likely early this afternoon, and again during the planning phase hours of the forecast, when a few light snow showers may accompany the Low's passage, particularly for those terminals closer to its track (KMVN-KEVV-KOWB).
- Below freezing temperatures are expected across the entire area for tonight and a Freeze Warning is in effect for tonight for the southeastern Texas Panhandle. - A slight pattern change this weekend may lead to cooler conditions and low chances for precipitation. (This afternoon through Monday night) Below average temperatures are forecast for this afternoon as cooler air remains in place behind the cold frontal passage from yesterday. Clear skies and light winds will lead to below freezing temperatures in the 20s area wide tonight. Breezy southwest surface winds will aid in bringing in warmer air for Monday and highs will warm back up into the upper 50s to mid 60s for the Panhandles. Lows Monday night should stay above freezing as winds will mostly remain around 10 mph or higher all night.
125 PM EST Sun Nov 9 2025 A strong cold front will move through tonight with some showers and a few thunderstorms. Cold, breezy conditions will hold through the middle of the week before temperatures moderate ahead of another, weaker cold front. The long advertised cold front is now pushing through the Western Carolinas and is on schedule to move across the area from about 00 and 06 UTC tonight. The cold front will be well offshore with dry, cold conditions in place through the period.
- Cold temperatures today with highs having a hard time getting above freezing.
1133 AM CST Sun Nov 9 2025 - A Freeze Warning is in effect through tomorrow morning, as low temperatures fall into the middle 20s north to near-freezing south. Low temperatures tonight will plummet into the middle to upper 20s north, while sites to the south straddle the freezing mark by daybreak. The upper level trough has plunged south towards the coast as anticipated, enveloping the entire ArkLaTex in a cold continental airmass.
Low (10-30%) chance of brief freezing temperatures in cold drainage areas stretching across McMullen County to Goliad County. Conditions are developing as expected following this morning's cold front.
804 AM PST Sun Nov 9 2025 Drier and warmer conditions will remain into Sunday as high pressure builds overhead. High clouds continue overhead as an upper- ridge progresses across the PNW.
520 PM CST Sun Nov 9 2025 Updated at 515 PM CST SUN NOV 9 2025 - There is a medium to high chance of freezing temperatures tonight, focused on the northern half of Central Alabama.
Otherwise, dry weather and warmer than normal temperatures are expected across the region through the middle of the upcoming week. * A trough of low pressure will bring gusty winds, cooler temperatures, and increased precipitation chances to the region late in the week. Midday satellite loop showed thin cirrus spilling down the front side of the ridge into our region.
Pattern Synopsis and Forecast: Upper trough dives south tonight and then shifts east through the Ohio Valley on Monday. As the winds shift a little more northwest due to the changes in the trough orientation, some of the lake bands will shift eastward bringing some inland, and thus Benzie and Grand Traverse county could get in on the accumulating snows. Cold Temperatures: Temperatures will tank to the lowest of the season tonight, with teens and 20s likely across much of the area.
The ridge set up over the western CONUS will persist as we enter the work week.
Surface temperatures are around freezing which is allowing snow to largely melt on roads. The orientation on the lake along with support from the upper level low and lake temperature/850 mb temperature differences around 20-25 C will support moderate to heavy accumulations in far southwest Michigan while the band remains overhead. - Another Round of Lake Effect Snow Monday into Monday Night As the trough axis begins to shift east of the lake tomorrow, northwest flow will take over and push the ongoing lake effect band onshore and inland.
The heart of the giant long wave cyclone makes mid Ohio River Valley passage late tonight into Monday. The strong PVA rotating across the area with the mean trof axis may even squeeze out a few flurries or light snow showers while this occurs, with best chances north and east closest to the center of the cyclone; would not be shocked to see a dusting on grassy surfaces, but no significant accumulations are expected. An upper low will slide south through the area with a chance of MVFR or lower snows and MVFR or lower ceilings at KEVV and KOWB around 15Z.
514 PM CST Sun Nov 9 2025 - Below freezing temperatures are expected across the entire area for tonight and a Freeze Warning is in effect for tonight for the southeastern Texas Panhandle. - A slight pattern change this weekend may lead to cooler conditions and low chances for precipitation. (This afternoon through Monday night) Below average temperatures are forecast for this afternoon as cooler air remains in place behind the cold frontal passage from yesterday. Clear skies and light winds will lead to below freezing temperatures in the 20s area wide tonight. Breezy southwest surface winds will aid in bringing in warmer air for Monday and highs will warm back up into the upper 50s to mid 60s for the Panhandles. Lows Monday night should stay above freezing as winds will mostly remain around 10 mph or higher all night.
Updated at 725 PM CST Sun Nov 9 2025 - Chilly tonight into Monday morning, with freezing temperatures expected across portions of the northern Permian Basin and in the higher terrain.
622 PM CST Sun Nov 9 2025 - A Freeze Warning is in effect through tomorrow morning, as low temperatures fall into the middle 20s north to near-freezing south. Low temperatures tonight will plummet into the middle to upper 20s north, while sites to the south straddle the freezing mark by daybreak. The upper level trough has plunged south towards the coast as anticipated, enveloping the entire ArkLaTex in a cold continental airmass.
505 PM CST Sun Nov 9 2025 Updated at 504 PM CST Sun Nov 9 2025 - Chilly tonight into Monday morning, with freezing temperatures expected across portions of the northern Permian Basin and in the higher terrain.
- Moderate to heavy lake effect snow is expected this afternoon and overnight in the higher elevations of Iron and Ashland counties, with 3 to 8 inches of new snow possible.
640 PM EST Sun Nov 9 2025 Rain showers are moving through the region this evening ahead of a cold front. Cooler temperatures settle in overnight behind the front allowing rain showers to transition to snow.
- An atmospheric river storm system mid to late week will bring widespread precipitation, gusty winds, cooler temperatures, and mountain snow.
Later tonight, that should aid in dropping temperatures to the lower to mid 20s as currently forecast. The thermal trough will actually be dragged further over the area tonight by a strong short wave over western Wisconsin embedded in the broader long wave trough. The turnaround in temperatures will be quite pronounced with a fast-paced pattern in the wake of the long wave trough's departure.
1052 PM CST Sun Nov 9 2025 Updated at 1051 PM CST Sun Nov 9 2025 - Chilly tonight into Monday morning, with freezing temperatures expected across portions of the northern Permian Basin and in the higher terrain.
Low (10-20%) chance of brief freezing temperatures. Expect today to be much cooler behind the front with highs only topping out in the 60s across South Texas.
Only the NAM saturates the lower atmosphere but still has the lowest kilometer quite dry.
Updated at 1129 PM CST Sun Nov 9 2025 - Only a bit warmer today with most locations seeing highs in the lower 60s with a steady south to southwest breeze.
1231 AM EST Mon Nov 10 2025 Rain showers are moving through the region this evening ahead of a cold front. Cooler temperatures settle in overnight behind the front allowing rain showers to transition to snow.
Elsewhere, we should fall into the teens, albeit more slowly for cloudy areas which may remain in the lower 20s depending on how slowly stratus clears. Wind chills this morning drop to near zero and into the lower teens so bundle up as you head out the door.
resulting in widespread freezing to hard-freezing conditions. -Wind chills will drop to the lower teens Monday morning for portions of northern Arkansas and the the higher terrain of the Ozarks.
High clouds will move overhead tonight into Monday as an upper level trough moves into southern British Columbia and flattens the ridge over our area. Temperatures on Monday will continue to warm, especially across the southern half of the area as the flow aloft transitions from northwesterly to west-southwesterly bringing in a warmer air mass. Highs will reach the 60s across the south, but warming will be more muted across the lower Snake Basin (including the Treasure Valley) and in northern areas, where temperatures will only increase by a few degrees. Inversion will strengthen over the area through Monday as an upper ridge brings warming aloft. Some improvement is expected Tue/Wed after the passage of an upper trough brings in cooler air aloft. A pattern change later in the week will replace the stagnant air mass with cooler and wetter conditions Thur/Fri.
Main impacts are expected to be reduced visibility and some slick spots on mainly bridges and overpasses. Secondary disturbance dropping southeast across the back side of the deep upper low affecting the tonight. Expect cold lows in the lower 20s with wind chill readings in the lower teens. The mid level trof shift off to the east with northwest flow in its wake. Temperatures reach highs in the upper 30s to the lower 40s.

The strong PVA rotating across the area with the mean trof axis may even squeeze out a few flurries or light snow showers while this occurs, with best chances north and east closest to the center of the cyclone; would not be shocked to see a dusting on grassy surfaces, but no significant accumulations are expected. 4-5kft ceilings may come and go some overnight, but an upper low is still expected bring another area of MVFR ceilings through KEVV and KOWB in the morning. Northwest winds will be gusty overnight, but will increase early in the morning approach of the upper low.
1117 PM CST Sun Nov 9 2025 Updated at 1116 PM CST SUN NOV 9 2025 - There is a medium to high chance of freezing temperatures tonight, focused on the northern half of Central Alabama.
1230 AM PST Mon Nov 10 2025 * Dry weather and warmer than normal temperatures are expected across the region through the middle of the week. * A trough of low pressure will bring gusty winds, cooler temperatures, and increased precipitation chances to the region late this week.
519 AM CST Mon Nov 10 2025 - Cold today but warmer through the rest of the week. Early morning satellite/sfc analysis shows 1036mb high centered across KS/NE with the unusually cold (-41C)and compact upper low across IL/IN region. The high shifts east of the region tonight with return flow/LLJ developing which should aid in strong WAA just above the sfc with some gusty winds likely after midnight into sunrise Tues. A weak cold front will sag into the area during the day Tuesday however most areas will see much warmer temps in the 60s. Both ECMWF and GFS show the next longwave trough approaching by the weekend with various ideas on how the energy will evolve within the trough itself.
High temperatures peak today with our ridge still sitting over us. Start preparing now for this storm, like bringing in any decorations, preparing vegetation for freezing temperatures, or if you're in the mountains, preparing for our first decent snow of the season.
High pressure will bring dry and mild conditions to Utah and southwest Wyoming through midweek.
503 AM CST Mon Nov 10 2025 Updated at 503 AM CST Mon Nov 10 2025 - Only a bit warmer today with most locations seeing highs in the lower 60s with a steady south to southwest breeze.
This will continue through sunrise with multiple areas dropping to near or below freezing. Warm up will be rapid later this morning and have no issues with the model blend high temperatures this afternoon in the low to mid 60s. This will effectively keep temperatures much warmer with lows mainly in the 40s overnight. (Tuesday night through next Monday) High pressure across the western U. As this higher pressure develops overhead, we will see temperatures across the region increase and lead to highs in the 80s by the middle of this week. Overnight lows will be above freezing in the lower to middle 40s.
Low probability for exceeding 1 inch at the highest elevations.
Broken to overcast low-level clouds remain across far western and central Minnesota, allowing Morrison and Todd counties to remain four or five degrees warmer than surrounding locations. Elsewhere, temperatures have dropped into the low 20s and upper teens with mostly clear skies. As the system that brought us this burst of cold air exits towards the Great Lakes, ridging will build and bring our temperatures back to near normal by Tuesday. This will also contribute to a benign weather pattern through the workweek with high pressure overhead.
Main impacts are expected to be reduced visibility and some slick spots on mainly bridges and overpasses. Secondary disturbance dropping southeast across the back side of the deep upper low affecting the tonight. Expect cold lows in the lower 20s with wind chill readings in the lower teens. The mid level trof shift off to the east with northwest flow in its wake. Temperatures reach highs in the upper 30s to the lower 40s. Surface ridging will briefly build into the middle Ohio Valley Tuesday.
308 AM PST Mon Nov 10 2025 * Dry weather and warmer than normal temperatures are expected across the region through the middle of the week. * A trough of low pressure will bring gusty winds, cooler temperatures, and increased precipitation chances to the region late this week.
307 AM CST Mon Nov 10 2025 * Well-below normal/seasonal temperatures through Tuesday morning * Warmer temperatures expected Tuesday afternoon.
Today through Tuesday night: Strong cold advection is underway and will continue through today as unusually cold and amplified upper level trough swings across the eastern CONUS. Near record lows in the low to mid 20s will be common outside of the Delta region. The thermal trough will exit quickly to the east Tuesday, and this will result in quick moderation of the temperatures as wind shifts to a more southerly direction.
Below freezing morning lows are possible in valleys east of Tucson including the Sulphur Springs Valley.
- An elevated wildfire threat will materialize west of I-35 on Tuesday due to low humidity, breezy south winds, and warmer temperatures.
405 AM PST Mon Nov 10 2025 Continued warmer inland today with areas of dense fog for coastal areas early this morning.
623 AM EST Mon Nov 10 2025 A broad trough will be over the region through Tuesday with several disturbances bringing snow showers and lake effect snow to the region.
One thing that has changed slightly is that hi-res models now show this band anchoring to the east side of the lake a bit more, likely due to lake-induced pressure trough and enhanced convergence as flow remains a bit more northerly than previously expected. Cass County Michigan will be in the cross-hairs for some of the highest totals and a warning may very well be needed there. A warm front is still slated to swing through the area on Tue and this could bring some additional, very light snow. A stronger warm front lifts through the region late Fri into Sat and may bring a few light rain showers. Rain then becomes likely along the associated cold front due to arrive late Sun.
Spotty flurries have been moving south across the forecast area this morning, driven by the center of the mid-level trough dropping south from the Great Lakes region through the mid- Mississippi Valley. These will end around sunrise as the low moves into the Southeast US. The mid-level trough will begin sliding east overnight and into tomorrow morning, causing mid-level flow to become northwesterly. Delia Mid-level northwesterly flow will persist through the work week as the exiting trough stalls over the East Coast and a ridge sits over the West Coast.
Low (10-20%) chance of brief freezing temperatures. Expect today to be much cooler behind the front with highs only topping out in the 60s across South Texas. There will be a low chance that we will see widespread freezing temperatures, though in our usual drainage areas it will definitely be possible.
We are eventually anticipating lows in the mid 20s will be common just before sunrise -- though temperatures are trending just a little warmer, thanks to mixing from the winds. The combination of this cold and the gusty winds will make it tough for wind chill values to climb above the freezing mark.
357 AM CST Mon Nov 10 2025 - Cold today but warmer through the rest of the week. Early morning satellite/sfc analysis shows 1036mb high centered across KS/NE with the unusually cold (-41C)and compact upper low across IL/IN region. The high shifts east of the region tonight with return flow/LLJ developing which should aid in strong WAA just above the sfc with some gusty winds likely after midnight into sunrise Tues.

536 AM CST Mon Nov 10 2025 * Well-below normal/seasonal temperatures through Tuesday morning * Warmer temperatures expected Tuesday afternoon.
- Robust warm-up Tuesday with highs well into the lower to mid 70s.
A ridge of high pressure at the surface was sprawling over Kansas early this morning. Under the ridge we have calm winds, clear conditions and very dry air allowing for excellent radiational cooling. Below average temperatures will persist today as the area of high pressure translates slowly southeastward away from the area. A trough of low pressure will bring southwest low level flow to the area on Tue allowing temperatures to quickly moderate. a mid/upper ridge is progged to amplify and move eastward over the central CONUS.
High pressure center is moving into western MN early this morning with surface winds turning light southerly in E ND with a NW light wind in MN. This should help push the lower clouds that cover all but the far western fcst area gradually out as winds drier airmass at 850 mb should mix more toward the surface. Temps will be a bit warmer today, especially west of the valley where warmer air will begin to reach the suface. Most areas into the low-mid 30s today with near 40 possible Devils Lake. Also this early morning areas of fog is forming in more areas along the low cloud, clear interface roughly from Jamestown area north thru Devils Lake, Lakota, to Langdon.
518 AM CST Mon Nov 10 2025 - One more round of freezing temperatures across the Four State Region Monday night, into Tuesday morning. By the morning, temperatures at or below freezing will be spread across the region.
* Well-below normal/seasonal temperatures through Tuesday morning * Warmer temperatures expected Tuesday afternoon.
High pressure centered over the southern Plains and lower Mississippi Valley will continue weakening as it settles along the Gulf Coast.
This will continue through sunrise with multiple areas dropping to near or below freezing. Warm up will be rapid later this morning and have no issues with the model blend high temperatures this afternoon in the low to mid 60s. This will effectively keep temperatures much warmer with lows mainly in the 40s overnight. (Tuesday night through next Monday) High pressure across the western U. As this higher pressure develops overhead, we will see temperatures across the region increase and lead to highs in the 80s by the middle of this week. Overnight lows will be above freezing in the lower to middle 40s. Strong gusty south to southwest winds are expected Tuesday morning, with the highest gusts 30 KTS at KABI, and 27 KTS at KSJT and KBBD.
-A significant cold front will continue to blast through the Florida Keys today. This will result in much cooler temperatures along with windy conditions developing for the first part of the work week. -Temperatures expected to return to slightly below normal by the end of the week as a high pressure system sets up over the northern Gulf. The leading edge of a strong cold frontal passage continues to push through the Florida Keys at this late morning hour. From synopsis, potent cold front will continue push through the Florida Keys marine zones this afternoon, bringing fresh to strong northerly breezes in its wake, peaking overnight. (15Z TAFS) A strong cold front will continue to push through the island terminals this afternoon.
155 PM CST Mon Nov 10 2025 - Subfreezing temperatures are expected again tonight with lows in the mid 20s.
910 AM PST Mon Nov 10 2025 * Dry weather and warmer than normal temperatures are expected across the region through the middle of the week. * A trough of low pressure will bring gusty winds, cooler temperatures, and increased precipitation chances to the region late this week.
Combined with low relative humidity, an increased fire danger will exist, especially from the highway 80 corridor southward where a Red Flag Warning is in effect through 6 pm. -Temperatures will drop into the lower 20s tonight, ending the growing season for all of Central Alabama.
- Warmer weather this week. This high will move southeast toward Louisiana/Mississippi tonight while lee troughing develops across the High Plains, so south/southwesterly winds will increase overnight. Temperatures will generally remain above freezing except perhaps in some sheltered areas across north central and southeastern Oklahoma.
