CURRENTS & TONIGHT: A cooler day continues! Taking a look across the area, high level cirrus continues to filter into the region this afternoon mainly in response to the increasing mid-level warm air advection (WAA) progressing across the Dakotas. With this in mind and a deeper snowpack of 2-4 inches across the area, tried to trend temperatures a bit cooler for the day using a combination of the BCCONSRaw and CONSShort. This would have highs peaking in the low 30s east of the James River Valley and mid 30 to low 40s west of there with the mildest conditions closer to southcentral SD which is a bit more reasonable given the conditions. From here, we'll likely see a non-dirunal temperatures trend overnight as a warm front progresses across the area.
-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 big weather story for the Keys today is the passage of the previously mentioned cold front. These northerly winds will bring in a dry and cooler air mass to our CWA with dew points plunging into the 40s and low temperatures extending below 60 degrees. 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.
- Marine hazards are expected behind the strong cold front for Monday and Tuesday. A strong cold front pushed through overnight bringing with it record breaking cold air. Most of us will be seeing record cold temperatures for tomorrow morning with the Nature Coast getting at or below freezing.
108 PM 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.
Updated at 1133 AM CST Mon Nov 10 2025 -A High Risk of Rip Currents and High Surf Advisory are in effect into this evening along the Lower Texas beaches. -Overnight low temperatures tonight will fall into the upper 30s across portions of the Ranchlands with upper 40s in the lower to mid Valley. -Small Craft Advisories are in effect for the waters off the lower Texas coast into this afternoon. The cooler (and refreshing) conditions will continue to through Tuesday. Afternoon high temperatures today will be in the upper 60s to low 70s across the region, finally feeling like fall! Tonight will be the coolest night of the forecast period with lows ranging from the upper 30s in portions of the northern Ranchlands to upper 40s across the lower Valley.
- An elevated wildfire threat will materialize west of I-35 on Tuesday due to low humidity, breezy south winds, and warmer temperatures. (This afternoon through Tuesday) Another cool day is in store across the region in the wake of this weekend's cold front. Another chilly morning is expected on Tuesday, but most locations will remain above freezing with lows in the upper 30s to mid 40s. The main exception will be our East Texas zones where isolated areas may experience a light freeze in the low 30s. Warmer but breezy weather is expected the remainder of the day, with afternoon highs in the mid 60s to mid 70s. The warmer temperatures, low humidity, and breezy 15-20 mph southerly winds will result in an elevated wildfire threat west of the I-35 corridor.
There is a low probability of exceeding 1" at the highest elevations.
- A widespread freeze is expected across the forecast area tonight, with temperatures as much as 5 to 10 degrees below freezing. MSLP values with this high are near the max in this region for mid-November. Typically colder spots like the hilly northeast Mississippi or could see lows in the lower 20s. Tomorrow into the weekend: The deep upper-level trough and closed low pressure centered over the Midwest today will quickly pivot eastward and be followed by a slower building upper-level ridge over much of the country through late week.
One more night (and day) of this chilly plunge of polar air and the warmup ensues thereafter, but not before we continue our endurance of freezing temperatures with teens and 20s wind chills, which will persist tonight into Veterans Day.
Our region is under the influence of an upper level ridge, with the deep trough that impacted us over the weekend now over the eastern US. Tonight, an area of low pressure well to our north in Canada will swing a warm front through. While the better forcing for precipitation will be to our north closer to the low in Canada or east deeper into MN where better frontogenetical forcing exists, there should be just enough lift to get a little light precipitation to form on the MN side of the FA. If there were to be any pockets of freezing drizzle, duration between when it occurs and when temperatures get above freezing would be short, resulting in little to no impacts.
- A weather system for the weekend brings cooler conditions and low chances for precipitation. (This afternoon through Tuesday night) A ridge of higher pressure is actively building across the southern plains with only a slight interruption on Tuesday from a small upper level weather system. The small weather system on Tuesday has a high chance of pushing a weak cold front across the panhandles during the afternoon hours of Tuesday.
Water vapor imagery this afternoon shows a convectively-enhanced meso-low rapidly moving south of the Ohio River Valley, followed by a pronounced ridge nosing into the central US.
1054 AM CST Mon Nov 10 2025 - One more round of freezing temperatures across the Four State Region Monday night, into Tuesday morning.
Even with a sunny sky, temperatures are slow to climb today with Arctic high pressure overhead.
Nonetheless, with air temperatures still near or just below freezing, will continue with the current Winter Weather Advisory into early afternoon. However, as the low level flow becomes more northwesterly heading into tonight, we will begin to see a fetch off of Lake Michigan set up across northern/eastern portions of our area overnight. With temperatures dropping into the lower 20s overnight, this could lead to some additional slick spots on area roadways later tonight. Highs on Tuesday will range from the mid 30s north to the lower 40s south. Lows Tuesday night will be in the low to mid 30s.
- An upper-level system brings cooler temperatures, gusty winds, and low (10-25%) rain chances this weekend. (This afternoon through Tuesday night) Water vapor imagery depicts upper-level ridging building in from the west as forecast, leaving our area under northwest flow aloft. This coupled with southerly return flow at the surface allows for afternoon highs to be a little warmer than yesterday's. The upper-level ridge axis moves closer to our area Tuesday and surface winds become southwesterly. Downslope flow continues Tuesday night, leading to lows being 3-6 degrees warmer than previous night.
1215 PM CST Mon Nov 10 2025 - One more round of freezing temperatures across the Four State Region Monday night, into Tuesday morning.
as morning lows tended to drop into the upper teens in rural areas while urban areas tended to stay a little warmer in the lower 20s. The large parent trough/cut-off mid-upper low responsible for the Arctic airmass outbreak continued to gradually shift eastward today, allowing for general cold and uncomfortable conditions to ease. This general story continues through the remainder of the work week as the large scale pattern gradually shifts from an elongated western ridge - eastern tough pattern.
(This evening through Tuesday) Lee trough will strengthen Tuesday, with strong gusty southwest winds developing toward sunrise in the Big Country and mid morning farther south. Wind gusts of 25 to 35 mph expected, with the higher gusts in the Big Country. (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.
Currently, a deep upper level trough is digging across the eastern U. with ridging building over the Desert Southwest. At the surface this translates to a 1038mb high pressure centered over the Central and Southern Plains. Afternoon high temperatures today will top out in the lower to middle 40s with light and variable winds. As we move forward into tonight and tomorrow, the upper level trough to the east will begin to lift out over the East Coast and ridging from the west will build over the Plains. A warming trend will commence beginning tonight with overnight lows only falling into the lower to middle 30s. With high pressure dominating the weather patter this week, mostly sunny and dry conditions are expected.
1122 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. Light and variable wind will continue until this evening as high pressure remains overhead.
1250 PM 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.
Mild and dry conditions are expected today with high level clouds across the area as a weak upper level trough moves across the Idaho Panhandle. This trough should weaken the upper level ridge significantly enough by this evening to scour out much of the valley inversion that has been in place over the weekend. The inversion will hold highs near normal across the lowest elevations, where temperatures will be slightly lower but still above normal. The ridge rebuilds northward again on Tuesday, with the axis positioned east of the area, allowing for increased southwesterly flow and warming aloft. A temperature inversion will keep mixing heights below 2kft today for the lower valleys. Tuesday will see some improvement in the wake of a passing upper trough that cools temperatures aloft.
Heading into the latter half of the week, upper level ridging builds back into the region allowing temperatures to gradually warm each day and help melt the remaining snowpack.
Cooler conditions expected for the middle to end of the week.
653 PM CST Mon Nov 10 2025 - One more round of freezing temperatures across the Four State Region Monday night, into Tuesday morning.
Nonetheless, with air temperatures still near or just below freezing, will continue with the current Winter Weather Advisory into early afternoon. However, as the low level flow becomes more northwesterly heading into tonight, we will begin to see a fetch off of Lake Michigan set up across northern/western portions of our area overnight. With temperatures dropping into the lower 20s overnight, this could lead to some additional slick spots on area roadways later tonight. Highs on Tuesday will range from the mid 30s north to the lower 40s south. Lows Tuesday night will be in the low to mid 30s.
709 PM EST Mon Nov 10 2025 - Lake effect snow continues tonight - Another round of rain/snow Tuesday - Milder conditions ahead PATTERN SYNOPSIS/FORECAST: Elongated N-S oriented high pressure across the central US on downstream side of ridge axis stretching from Nevada into the central Canadian Prairies. Upper low to our south. with upstream ridging to build in tonight.
High pressure will remain in place through midweek continuing dry stable conditions.
323 PM 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, much cooler temperatures, and increased precipitation chances to the region late this week.
519 PM CST Mon Nov 10 2025 Updated at 517 PM CST Mon Nov 10 2025 -A High Risk of Rip Currents and High Surf Advisory are in effect into this evening along the Lower Texas beaches. -Overnight low temperatures tonight will fall into the upper 30s across portions of the Ranchlands with upper 40s in the lower to mid Valley. -Small Craft Advisories are in effect for the waters off the lower Texas coast into this afternoon. The cooler (and refreshing) conditions will continue to through Tuesday. Afternoon high temperatures today will be in the upper 60s to low 70s across the region, finally feeling like fall! Tonight will be the coolest night of the forecast period with lows ranging from the upper 30s in portions of the northern Ranchlands to upper 40s across the lower Valley.
517 PM CST Mon Nov 10 2025 Updated at 508 PM CST MON NOV 10 2025 -Temperatures will drop into the lower 20s tonight, ending the growing season for all of Central Alabama.
530 PM CST Mon Nov 10 2025 - A widespread freeze is expected across the forecast area tonight, with temperatures as much as 5 to 10 degrees below freezing. MSLP values with this high are near the max in this region for mid-November. Typically colder spots like the hilly northeast Mississippi or could see lows in the lower 20s. Tomorrow into the weekend: The deep upper-level trough and closed low pressure centered over the Midwest today will quickly pivot eastward and be followed by a slower building upper-level ridge over much of the country through late week.
Then an overall ridging pattern will keep temperatures above average this week.
Issued 354 PM CST Mon Nov 10 2025 Tonight through Tuesday night: Increasing clouds tonight with lows in the low 20s and northwesterly winds diminishing and becoming southwesterly by Tuesday morning as a weak warm front lifts west to east across southern Wisconsin. Very dry air in the low levels will prevent the majority of snow from reaching the surface; but still expecting at least general coverage of 15-30 percent through the overnight hours into Tuesday morning. Any lingering precipitation will move offshore into Lake Michigan by midday, with highs reaching the low 40s in the afternoon hours. Winds become less gusty and shift to westerly overnight Tuesday as low pressure pushes southeastward into the eastern Great Lakes region.
212 PM 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, much cooler temperatures, and increased precipitation chances to the region late this week.
High pressure extended from the Southern Plains to the Upper Midwest and northwestern Ontario this afternoon. As the ridge axis aloft shifts eastward this evening, a trough will move from the Northern Plains into the Upper Midwest overnight. Light snow showers associated with an eastward moving warm front are expected starting this evening and pushing east of the region by sunrise Tuesday morning.
Temperatures are currently below freezing, but will slowly rise above freezing in the late morning. Even though temperatures aloft will be cold enough to support flurries, previously mentioned warming surface temperatures above freezing will mitigate any impacts or accumulations. A broad upper level ridge is expected to grow through mid week and slowly move eastward into the weekend. West-southwest winds will continue to pull in warmer and drier air from the southern Plains for a gradual warming trend through the end of the week.
Temperatures prior to sunrise will range from the mid 20s to low 30s, with wind chills in the low 20s. Temperatures as of midnight are already in the upper 20s across interior counties, with freezing temperatures already reaching as far south as the I-10 corridor. Forecast remains on track for the remainder of the night, with most interior areas dropping a few more degrees into the mid 20s, and even a few areas within a mile or two of the immediate coastline dropping to below the freezing mark. The anomalously deep upper trough that resulted in this early season arctic airmass will quickly lift away from the local region later today.
1256 AM PST Tue Nov 11 2025 * Dry weather and warmer than normal temperatures are expected across the region through the middle of the week. * High confidence that a trough of low pressure will bring gusty winds and increased precipitation chances to the region the second half of the week, but low confidence in details and expected impacts.
235 AM CST Tue Nov 11 2025 - Much warmer today with high fire danger in northeast Nebraska.
(Tonight through next Monday) Lingering CAA in the wake of a strong cold front has kept temperatures mainly in the 30s for the last several hours, continuing to drop. Current forecast lows are in the low 20s by sunrise Tuesday, but a northwest breeze will put a chilly bite on the air and send wind chills into the teens.
1141 PM CST Mon Nov 10 2025 - A widespread freeze is expected across the forecast area tonight, with temperatures as much as 5 to 10 degrees below freezing. MSLP values with this high are near the max in this region for mid-November. Typically colder spots like the hilly northeast Mississippi or could see lows in the lower 20s. Tomorrow into the weekend: The deep upper-level trough and closed low pressure centered over the Midwest today will quickly pivot eastward and be followed by a slower building upper-level ridge over much of the country through late week.
Low pressure over southern Canada has a north/south oriented warm front associated with it. The Wisconsin precipitation is oriented along the warm front and that will move across the cwa today.
213 AM EST Tue Nov 11 2025 An upper level low will be over the region today, with potential for snow showers and lake effect snow.
Drier conditions are expected across western Washington on Tuesday as high pressure builds back into the region.
1249 AM EST Tue Nov 11 2025 Updated at 1245 AM EST Tue Nov 11 2025 - Zero or slightly below zero wind chill values continue in the higher terrain through mid morning. For today, very cold temperatures with wind chill values around or slightly below zero will continue in the higher elevations through shortly after daybreak today. While the upper levels retain some degree of cyclonic flow aloft, Pacific high pressure will move in from the west by Wed, allowing temperatures to rebound into the 50s to low 60s Wed afternoon, and firmly into the 60s across low elevation areas by week's end in response to a strong upper ridge developing over the central CONUS.
It's the coldest morning of the season as surface ridging shifts across the area, though filtered high clouds are preventing conditions from being quite as cold as they might have otherwise been. Nevertheless, as the ridge shifts eastward, low level flow will turn southerly today commencing a moderating trend that will continue through the week, with seasonably warm conditions returning by the daytime tomorrow. It will remain dry through the majority of the forecast period thanks to stout upper ridging over the central CONUS.
- Warmer weather this week. Combined with much warmer temperatures and limited moisture return (RHs 17-22%), fire weather conditions will easily reach into the elevated category during the daytime hours.
Periods of high clouds will move overhead tonight as an upper level trough moves by to the north. On Tuesday, the axis of a low amplitude upper level ridge will move overhead. The valley inversion will be weakened by the departing trough, allowing valley high temperatures to climb a couple of degrees from today. Otherwise, winds will be light with mostly sunny skies as the ridge moves overhead. High pressure and subsidence aloft will keep a temperature inversion in place on Tuesday with mixing heights near or slightly below 2kft in the lower valleys. This will be a slight improvement from Monday in the wake of a passing upper trough that will cool temperatures aloft and weaken the inversion.
Cooler conditions are likely for the middle to end of the week.
Thermal profiles remain marginal, so precipitation type will vary with higher terrain inland leaning towards mainly snow, while lower elevations and coastal areas will see more of a rain/ snow mix or primarily rain during the afternoon as surface temperatures climb above freezing. No major impacts expected, but the combination of wet snow and wind (along with freezing temperatures tonight) could lead to some slick travel today and tonight.
Updated at 1130 PM CST Mon Nov 10 2025 - An Arctic high pressure system will bring temperatures to near or below freezing this morning across much of the area.
Temperatures continue to fall quickly with much of the area already at or below freezingunder clear skies.
The dying front and the upper trough will bring some very minor rain chances to the coast and into northern Douglas County through this afternoon, but we're really not expecting much, and it might be difficult to find many locations where precipitation is measurable. Fog and low stratus are likely to return to area valleys tonight, once the higher clouds exit the region and winds calm.
Mid level full latitude trof to continue shifting off to the east leaving northwesterly flow across the region. Highs today will range from the mid 30s north to the lower 40s south.
1116 PM EST Mon Nov 10 2025 - Lake effect snow continues tonight - Another round of rain/snow Tuesday - Milder conditions ahead PATTERN SYNOPSIS/FORECAST: Elongated N-S oriented high pressure across the central US on downstream side of ridge axis stretching from Nevada into the central Canadian Prairies. Upper low to our south. with upstream ridging to build in tonight.
One last morning of at or sub-freezing temperatures across the region before we begin the quick rebound to what will feel like a spring temperature profile. Deep troughing across the SE CONUS will quickly shuffle east with upper-ridging wasting no time in trying to fill in where it once stood. Overnight lows will follow a similar regime with a transitions from the freezing lows to more milder temperatures. Looking to Tuesday specifically, the shift in the overall wind direction to southerly will play a key role in seeing highs about 10-15 deg F warmer when compared to Monday. Compared to last night, TOA and speed have become some of the bigger questions surrounding the low.
-A significant cold front traversed the Florida Keys earlier today. Much cooler temperatures along with windy conditions developed and will last 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. From synopsis, fresh to strong northerly breezes will peak overnight in the wake of a cold front that pushed across the Florida Keys marine zones earlier today. Winds will shift out of the northeast and gradually slacken through the week while an area of high pressure builds in behind the front.
- Warming trend with dry weather into end of the week, then cooler temperatures, a low but nonzero chance of rain late week into the weekend with an upper storm system.
