919 AM EDT Sat Nov 01 2025 High pressure will dominate through most of the weekend, moving offshore Sunday.
602 AM CDT Sat Nov 1 2025 Updated at 602 AM CDT Sat Nov 1 2025 - Cool weather is expected today, with dry and warmer weather forecast Sunday and beyond. At the surface, the attendant cold front was moving through the CWA, with brisk, northerly winds trailing behind. The combination of CAA and strong subsidence aloft will keep high temperatures a few degrees below seasonal norms, with highs peaking in the lower-middle 60s amidst full insolation.
202 PM EDT Sat Nov 1 2025 A cooler airmass will flow over the lower Great Lakes this weekend with localized bands of lake effect rain southeast of the lakes through Sunday morning.
(Tonight) Despite overcast skies, WAA from SSW flow has allowed afternoon temps to rise to the high 50s to low 60s. As the front and low pressure moves through, overcast conditions will continue in addition to light to moderate rain. The overcast conditions will keep temps several degrees warmer than previous nights with lows in the mid 40s.
- The highest elevations of the Smoky Mountains and mountains of far southeast Tennessee could experience of mixture of sleet and snow grains with the showers Sunday afternoon.
(This evening through Sunday night) Upper trough over the Great Lakes continues to dive over the Ohio and Mississippi Valley as it exits to the east. As a result we'll transition out of this cooler northerly flow to a more southerly flow tonight. While warmer air will be moving in, we'll still have fairly light winds tonight and mostly clear skies. So temperatures will be down in the low to mid 30s for most areas. Sunday we'll have southwest winds and high pressure moving over the area. Sunday night will be milder with lows in the 40s give the warmer temperatures moving into the area.
345 PM EDT Sat Nov 1 2025 High pressure builds in tonight and Sunday before departing to the east coast Sunday night.
Updated at 1215 PM CDT Sat Nov 1 2025 - Isolated to scattered showers and thunderstorms are expected to develop ahead of the cold front throughout the late evening and late night hours tonight, rising probabilities of rain to a medium to likely (40-60%) chance across the eastern half of Deep South Texas.
Fair/comfortable wx is expected for much of the upcoming week as mid-upper ridging builds into the region early in the week. Despite the ridge weakening/flattening beyond Wed and a light onshore flow in place, the low level moisture return isn't impressive. 47 (12Z TAF Issuance) Generally VFR conditions will prevail through the period with increasing mid and high level clouds through this afternoon ahead of an approaching cold front. Fowler With the combination of an incoming cold front and upper level disturbance, look for an increase in shower and thunderstorm activity as the afternoon and evening progresses.
303 PM CDT Sat Nov 1 2025 - Showers gradually diminish this evening, but drier and colder temps around or below freezing temps tonight. Issued 258 PM CDT Sat Nov 1 2025 Tonight through Sunday: The upper-level trough continues to slowly move southward into the Mid-Mississippi River Valley this evening while the surface meso-low over Lake Michigan moves into the far southeastern part of the Lake. Also expecting clouds to gradually clear overnight as well and will allow for temps to dip into the 20s for inland areas west of the Kettle Moraine, while areas along and east look to stay a bit warmer in the low to mid 30s. expect winds to gradually pick up through the afternoon as the pressure gradient tightens across WI as low pressure tracks across Manitoba into Ontario through Sunday evening.
314 PM EDT Sat Nov 01 2025 High pressure will extend across NC through Sunday.
205 PM EDT Sat Nov 1 2025 As winds and lake effect rain showers dissipate this evening, dry high pressure takes over for the remainder of the weekend.
220 PM MDT Sat Nov 1 2025 - High pressure is in control, with clear skies and much above normal temperatures prevailing through at least midweek.
Shallow stratus/stratocumulus has overspread the area associated with the upper low moving southeast out of southeast Iowa, with north winds helping to keep temperatures in the middle 40s to lower 50s early this afternoon. Despite this, have still gone on the cooler side of guidance for lows tonight. SREF and NBM temperature spreads are rather small through midweek with NBM high temperatures on the higher end of its spread seeming to be reasonable give limited clouds and decent mixing.
235 PM CDT Sat Nov 1 2025 - Widespread subfreezing temperatures tonight (>75% chance for lows less than 32 for nearly all of the forecast area, except the urban cor of KC).
Peripheral flow around troughing continues with embedded vorticity producing showers and a few thunderstorms. This meridional flow will transition to quasi-zonal flow over the next 48-72 hours as the trough shifts eastward. Ridging will shift in overnight, allowing reinforced radiational cooling that boosts frost development near the Ouachita Mtns. With zonal flow continuing across the area through the rest of the forecast period, most longwave troughs will remain north of the Four State Region, diverting active weather to our north and keeping the area dry.
Afternoon temps are seasonably cool, ranging from the mid 40s across the northwestern highlands to near 60 degrees in the Lower Susq Valley. However, hires model data shows an uptick in mid and high clouds downstream of closed upper low tracking across the Mid MS Valley.
- Much cooler and drier air continues through the weekend.
Highly amplified pattern with a large area of low pressure sitting across the central plains and a ridge axis encompassing much of the western CONUS remains the focal point regarding the observational weather expected across western South Dakota and eastern Wyoming for the upcoming week. High cirrus are spilling over the ridge axis allowing for temperatures to no rebound as much today with temperatures holding into the upper 40s to low 50s across the region. The first arrives tomorrow and this will be a fast moving, dry front that will bring slightly cooler temperatures but noticeably stronger northerly winds to portions of northwestern South Dakota.
202 PM EDT Sat Nov 01 2025 High pressure will dominate through most of the weekend, moving offshore Sunday.
- Increasing clouds and a few showers or thunderstorms expected this afternoon ahead of a weak upper trough and cold front.
With high pressure building into the area, dry and cool weather is expected for Sunday.
As heights continue to rise with the building ridge, the main story in the near term remains the gusty winds. Additionally, directly behind the cold front CAA will aid in providing downward transport of the winds which may allow the Harlowton area to see its strongest winds early afternoon. Later in the week there is a signal that a potentially stronger trough may make its way into the Northern Rockies which could provide us another chance for gusty winds gusts and also maybe some more widespread precipitation.
Currently aloft, a progressive ridge is moving through the Dakotas with zonal flow up stream, extending to the Pacific Ocean. At the surface, the incoming impactful low pressure is sitting in southern Alberta with a warm front across eastern Montana, and a cold front in central Montana. The warm front was originally forecast to move into western North Dakota today and warm temperatures into the upper 50s, but it has since stalled in Montana. By sunrise Sunday morning that cold front will be knocking on North Dakota's northwestern door. The cold front looks to enter the state late morning into the northwest and north central, and begin cooling temperatures and increasing wind speeds.
209 PM EDT Sat Nov 1 2025 High pressure builds in tonight and Sunday before departing to the east coast Sunday night.
Upper low over the midwest will sag south today and Sunday, eventually moving into the southeastern U. Moisture, overall limited in nature, will stream northward into the region later Saturday into Sunday, mainly confined to the southern/western zones closer to the low. Aforementioned upper low will move across the southeast U.
(Through Saturday) Cooler weather, with low chances for light rain/sprinkles, will greet us as we begin November 2025. Early morning water vapor imagery captures a southward-advancing upper low across portions of the Central Plains. An attendant cold front continues to advance southward across northern Oklahoma at this hour. Cooler temperatures and clearing skies will be left in the wake of the front by this afternoon and evening.
6", with the higher amounts in KY, and lower amounts in IN. Closed upper low will sink into the mid Mississippi River Valley through tonight, with deeper moisture pooling into our region ahead of this feature. Meanwhile, a surface cold front is already passing through the CWA, with cool advection taking over behind the system. Temps currently in the 55 to 60 degree range will fall into the low and mid 40s tonight. The closed upper low rotates through the TN Valley through tomorrow, with our widespread rainfall ending, and more scattered coverage lingering in our SE CWA.
Low pressure aloft drifts southeast today with tilted upper level ridging expected to build across the Northern Plains Sunday. Ahead of this milder return flow, high pressure will allow for chilly overnight temperatures again, with widespread upper 20s and lower 30s across the area.
219 PM EDT Sat Nov 01 2025 High pressure will dominate through most of the weekend, moving offshore Sunday.
Some rays of sun are peeking through the low clouds that remain in the low's wake. The cloud cover should prevent fog from developing overnight tonight, and keep it slightly warmer that areas with clear skies. This should be the last day this week with highs this "cool", as forecast temps are in the low to mid 50s for the next seven days.
(Rest of today and tonight) An upper-level trough to our northeast continues to depart. Our CWA is in the northerly flow regime aloft with surface ridging sliding overhead this evening and tonight.
1248 PM MDT Sat Nov 1 2025 KEY MESSAGES: - Windy conditions this afternoon and Sunday with the passage of a cold front. Strong west winds are developing across the region currently 50 to 60 mph about 2000 feet above the highest mountains.
238 PM EDT Sat Nov 1 2025 Updated at 234 PM EDT Sat Nov 1 2025 - An approaching upper low will bring increasing shower coverage Sunday afternoon into Sunday night with rainfall totals predominately a quarter inch or less with locally higher amounts. These clouds come in advance of an upper low currently dropping quickly southeastward across the Mid- Mississippi Valley. These denser upper clouds will help limit radiational cooling overnight with low temperatures Sunday morning some 10+ degrees warmer than this morning, particularly across north Georgia, though some patchy upper 30s remain possible in southeastern counties where cloud cover will not arrive as early. The upper low will slip from northern Alabama into western/north Georgia by Sunday night, bringing increasing coverage of rain showers.
Northwest flow aloft will turn more zonal on Sunday as an upper level ridge shifts eastward into southwestern United States. The axis of a mid-level thermal ridge will be situated over the plains, with 700-mb temperatures between +10C to +12C by the afternoon. Dry downslope winds off the Cheyenne ridge will likely promote RH values in the low-to-mid teens, with wind gusts up to 20 mph.
Ridging aloft this weekend will transition into more westerly flow this week as heights remain above seasonal normals.
1216 PM CDT Sat Nov 1 2025 -Scattered showers are anticipated over the northern half of Arkansas on Saturday associated with the passage of a cold front.
241 PM EDT Sat Nov 1 2025 Low pressure will track northeast across the Northern Maritimes today.
Updated at 1230 PM CDT Sat Nov 1 2025 - A cold front will move through the Mid-South tonight, bringing a few lingering showers and a wind shift to the northwest.
126 PM PDT Sat Nov 1 2025 * Dry weather with warmer than normal temperatures will prevail through the weekend.
626 PM CDT Sat Nov 1 2025 - Increasing clouds and a few showers or thunderstorms expected this afternoon ahead of a weak upper trough and cold front.
A large-scale ridge containing well above normal 500 mb hghts will begin to decrease in amplitude Sunday night as a weak s/wv moves into the ridge from the west. Strong cooling overnight and lack of decent mixing will keep areas north of the Mogollon Rim a bit cooler, but still just above normal.
The 12Z modeling suggests the low remains in the vicinity of the Bootheel thru 12Z Sunday. Given that proximity, and the inherent cloudiness associated thereof, the new guidance temps hover our lows just above freezing for all but our 2 coldest counties, which currently reside within the boundaries of the existing Freeze warning. After collaboration with LSX, and with our lows there (Carter-Wayne counties in SEMO) projected near 30 degrees, we'll continue the Freeze Warning headline, but drop the Watch counties further south and east, where temps should remain above freezing. A clap of thunder within/near the low center itself. The pattern transforms after the low ultimately pushes on out, which transitions us from the cool/damp environ to a warmer/drier one as the new week wears on.
751 PM EDT Sat Nov 1 2025 Dry and chilly high pressure system will take over the region after midnight and last through Sunday.
Cirrus are increasing over the east as the upper low to our west dives south of east. Afternoon temps are seasonably cool, ranging from the mid 40s across the northwestern highlands to near 60 degrees in the Lower Susq Valley. However, hires model data shows an uptick in mid and high clouds downstream of closed upper low tracking across the Mid MS Valley.
758 PM EDT Sat Nov 1 2025 High pressure builds in tonight and Sunday before departing to the east coast Sunday night.
The main vort max of this trough axis is anchored on the southern end and is expected to pass to our west and south overnight into Sunday.
- Widespread subfreezing temperatures tonight (>75% chance for lows less than 32 for nearly all of the forecast area, except the urban cor of KC).
630 PM CDT Sat Nov 1 2025 Updated at 609 PM CDT Sat Nov 1 2025 - Isolated to scattered showers and thunderstorms are expected to develop ahead of the cold front throughout the late evening and late night hours tonight, rising probabilities of rain to a medium to likely (40-60%) chance across the eastern half of Deep South Texas.
Temperatures going into Sunday morning will drop down into the 30s and a few areas across the north may drop down to freezing. Muscha (This evening through Sunday night) Upper trough over the Great Lakes continues to dive over the Ohio and Mississippi Valley as it exits to the east. As a result we'll transition out of this cooler northerly flow to a more southerly flow tonight. While warmer air will be moving in, we'll still have fairly light winds tonight and mostly clear skies. So temperatures will be down in the low to mid 30s for most areas. Sunday we'll have southwest winds and high pressure moving over the area. Sunday night will be milder with lows in the 40s give the warmer temperatures moving into the area.
643 PM CDT Sat Nov 1 2025 -Scattered showers are anticipated over the northern half of Arkansas on Saturday associated with the passage of a cold front.
Gentle SErly winds this afternoon will become strong and shift to the north- northeast tonight behind a cold front. RH values will increase today ahead of a weak cold front, although measurable rainfall with the front will likely be confined to the coastal plains.
641 PM CDT Sat Nov 1 2025 Updated at 633 PM CDT Sat Nov 1 2025 - A cold front will move through the Mid-South tonight, bringing a few lingering showers and a wind shift to the northwest.
Updated at 739 PM EDT Sat Nov 1 2025 - An approaching upper low will bring increasing shower coverage Sunday afternoon into Sunday night with rainfall totals predominately a quarter inch or less with locally higher amounts. These clouds come in advance of an upper low currently dropping quickly southeastward across the Mid- Mississippi Valley. These denser upper clouds will help limit radiational cooling overnight with low temperatures Sunday morning some 10+ degrees warmer than this morning, particularly across north Georgia, though some patchy upper 30s remain possible in southeastern counties where cloud cover will not arrive as early. The upper low will slip from northern Alabama into western/north Georgia by Sunday night, bringing increasing coverage of rain showers.
Fair/comfortable wx is expected for much of the upcoming week as mid-upper ridging builds into the region early in the week. Despite the ridge weakening/flattening beyond Wed and a light onshore flow in place, the low level moisture return isn't impressive. Rain chances will end as drier air moves in tonight in the wake of a cold front. Cotto With the combination of an incoming cold front and upper level disturbance, look for an increase in shower and thunderstorm activity as the afternoon and evening progresses.
742 PM EDT Sat Nov 1 2025 Low pressure will track northeast across the Northern Maritimes tonight.
High pressure brings a dry, seasonably cool start to the work week. Upper low over the midwest will sag south today and Sunday, eventually moving into the southeastern U. Moisture, overall limited in nature, will stream northward into the region later Saturday into Sunday, mainly confined to the southern/western zones closer to the low. Aforementioned upper low will move across the southeast U.
740 PM EDT Sat Nov 1 2025 A cooler airmass will flow over the lower Great Lakes through the rest of the weekend, with localized lake effect rain showers at times southeast of the lakes through Sunday morning.
A cold front pushing through the region is promoting a broken rain band nearest to ALW/PDT/DLS as of this TAF issuance, and given the radar mosaic trend and ceilings forecast anything lower than a brief MVFR in rain is unlikely (10-15%), and near PDT/ALW if at all. Of note, in areas where the morning inversion has eroded, southwest winds of 15-35 mph accompanied by gusts of 35-55 mph have mixed out the boundary layer resulting in abnormally warm temperatures of 65-80 degrees across the lower elevations.

The cold front and upper disturbance brought some aggressive storms for Nov. 1, but the post frontal conditions are not a significant alteration of the already deep troughing pattern over the eastern CONUS and the meridional pattern aloft over Central TX. The troughing pattern will shift east of TX with the northerly flow aloft weakening rapidly for Sunday. South winds will meagerly return today at mainly less than 10 mph and decoupling for another chilly night to make for near to slightly cooler than normal temperatures through Monday morning. Building high pressure aloft and abundant sunshine will usher the warming trend to shift temperatures back to slightly above normals by Monday afternoon.
(Today through Monday night) H500 troughing will slowly move away from the CWA today into Monday as high pressure builds in over Texas. As the high builds in today, temperatures should rise back up into the 70s for highs this afternoon with light south to southwest winds. As the upper level high becomes suppressed on Monday, a weak cold front will move down and is expected to stall around halfway through the Panhandles. Cooler temperatures across the north are expected with well above average highs across the south.
(Today and tonight) Subtropical ridging will continue to shift eastward towards W TX over the next 24 hours, as the large-scale trough pivoting across the eastern half of the U. Expect winds to diminish after sunset while remaining out of the southwest, with lows Monday morning bottoming out in the lower-middle 40s beneath a clear sky.
With high pressure building into the area, dry and cool weather is expected for Sunday. Milder temperatures are expected by Monday, although a passing cold front will bring some showers by late Monday into Monday night. On Sunday, high pressure will allow for a partly to mostly sunny sky. It will remain dry and quiet into Sunday night with a mostly clear sky and lows in the 30s as the high pressure area starts sliding offshore New England.
and they'll be done too once the cold front pushes out over the Gulf. This sets us up for a drier, cooler, and modestly windier day on Sunday. The lower friction of the water means winds will be strongest on the bays and Gulf tonight into the morning. While a bit breezy, this shouldn't bring us the same level of fire weather conditions we had experienced after the last cold front, despite dry air making its way into the area as well. High pressure looks to take control as early as Sunday afternoon, meaning winds should pretty quickly wane, and as ridging also takes command aloft, we're set up for a pretty chill week to come.
118 AM CST Sun Nov 2 2025 - A Freeze Warning remains in effect for the overnight into Sunday morning as temperatures drop to near freezing and below.
(Rest of today and tonight) An upper-level trough to our northeast continues to depart. Our CWA is in the northerly flow regime aloft with surface ridging sliding overhead this evening and tonight. Warmer temperatures will be located near the western edge of the CWA where a stronger pressure gradient will generate breezy southerly winds and get temperatures into the 70s. The pattern will continue to be progressive during the day on Monday, with a quite-strong-for-November 591 dam ridge centered over central Texas. Because we'll be closer to the center of the ridge, winds will be lighter than Sunday. With that said, much warmer mid- level temperatures will also manifest themselves in much warmer surface temperatures - from the 70s for most of the area to potentially the low 80s in western north Texas. Sunny skies will continue, with overnight lows being warmer.
Very benign pattern continues across the CWA as the eastern Pacific upper high persists over the area.
The upper level ridge will reach its peak of 588-589dm H5 heights today, likely helping to boost temperatures another degree or two across the area. Expect daytime highs across the lower deserts mostly ranging between 86-90 degrees for today and Monday.
140 AM MST Sun Nov 2 2025 - High pressure is in control leaving quiet weather and much above normal temperatures in place through at least midweek.
131 AM EDT Sun Nov 2 2025 High pressure builds in tonight and Sunday before departing to the east coast Sunday night.
118 AM MDT Sun Nov 2 2025 -Cool front will bring breezy weather to most of the region today, especially far NW SD -Mild and dry weather can be expected through most of the week with the next chance for precip toward the end of the work week Progressive westerly Pac flow will support mild conditions through most of the period as a series of weak low pressure systems traverse the Northern Plains.
Updated at 135 AM EDT Sun Nov 2 2025 - An approaching upper low will bring increasing shower coverage Sunday afternoon into Sunday night with rainfall totals predominately a quarter inch or less with locally higher amounts. These clouds come in advance of an upper low currently dropping quickly southeastward across the Mid-Mississippi Valley. These denser upper clouds will help limit radiational cooling overnight with low temperatures Sunday morning some 10+ degrees warmer than this morning, particularly across north Georgia, though some patchy upper 30s remain possible in southeastern counties where cloud cover will not arrive as early. The upper low will slip from northern Alabama into western/north Georgia by Sunday night, bringing increasing coverage of rain showers.
As we near daybreak and the upper low responsible for tonight's rain passes from north to south over the mid-state, showers will start to taper off from west to east.
