- Warmer temperatures return late this week and for the weekend. A pleasant day across most of the forecast area with sunny skies and warmer temperatures this afternoon. Northwest winds will persist behind the cold front on Thursday, keeping high temperatures a few degrees cooler than today. With an upper-level ridge over the west coast, skies will remain clear with minimal chances for precipitation. Friday begins with a low descending from Canada into the Great Lakes with ridging on its heels moving into our region.
Focus for the next 48 hours will be a 500 mb low in central Saskatchewan and short wave trough southeast into central ND at 08z. Temps while cool ahead of it where clouds are thinner, as clouds thicken in advance of trough temps do warm with temps and dew pts above 32F so not anticipating any wintry issues. This weekend will see upper ridge builds in briefly behind the departing 500 mb low.
Large, comma-shaped mid-latitude cyclone is wrapped up over western KY/TN this afternoon attempting to lift north. Poleward progress is slowed by high pressure over western Quebec. This same high pressure will result in a tight rainfall gradient locally over the next 24 hours. The GFS forecast sounding for the FWA area indicated the atmosphere was saturated or near saturation from the low levels through the mid levels. Kept the ceilings VFR at FWA for now, but may be too optimistic - and may have to add the lower MVFR clouds back in.
548 AM CDT Thu Oct 30 2025 - A deep low pressure system will continue to produce light, intermittent sprinkles and showers.
The expanse of the high cloud shield associated with the low pressure over KY/TN is also approaching from the south, which will gradually lift over southeast Michigan tonight and tomorrow. Rain showers and lower ceilings will eventually arrive under these clouds as the low moves into OH/PA. A large upper level low is currently centered near the Tennessee/Kentucky border this morning.
540 AM CDT Thu Oct 30 2025 - Cool temperatures this morning with some areas in the Hill Country approaching the freezing mark.
- Cooler than normal temperatures over the next few days.
Morning temperatures Friday remain about five degrees cooler than one would expect with overcast skies. Given ridging dominating the forecast, expect fair weather with temperatures running near normal to a little above normal today and Friday with generally light afternoon breezes, a little stronger Friday from the northwest. The current ridge-trough pattern across the CONUS will persist as we head into the weekend as yet another northern stream wave is absorbed by the downstream trough. However things begin to change through the weekend as an anomalous jet arrives to the PacNW coast and forces the upstream ridge eastward.
A warm front remains in the forecast for the end of the week, but current guidance keeps only the slights chances for coastal showers (15-20%) on Friday night so Halloween activities across the area should be under pleasant conditions.
631 AM EDT Thu Oct 30 2025 - Cooler with a few showers at times Friday into the weekend. Even with more filtered sunshine, it looks to be another mild afternoon for late October, with highs generally in the lower 50s and light north- northeast winds. How much sky cover will have a big say in overnight lows, more clouds keeps readings near the low to mid 30s, while areas that manage a few breaks in cloud cover could dip a bit cooler. Guidance continues to show less aggressive deepening of the upper- level trough as we head into the weekend, favoring more of a progressive pattern overall.
- Warmer temperatures return for the weekend with dry conditions. Much warmer observed early this morning aided by westerly winds and cloud cover ahead of the next cold front. Temperatures at 2 AM are 20 to 30 degrees warmer compared to this time yesterday, with readings in the 30s and 40s. Surface cold front is just starting to enter east central Wyoming and Carbon county. It will be breezy across the high plains, with northwest winds gusting up to 30-35 mph at times this morning through this afternoon. Models continue to trend cooler on Friday as deterministic models and ensemble guidances shows a deeper upper level trough which is placed further west compared to 48 hours ago. Some ensemble members place the trough far enough west to introduce some widely scattered rain/snow showers across the eastern plains.
714 AM EDT Thu Oct 30 2025 Updated at 708 AM EDT Thu Oct 30 2025 - Additional light rain is expected today with coverage shifting towards the higher elevations tonight with breezy conditions. Light snow is possible in the highest elevations.
Area of light rain that was just ahead of it, has moved east away from the trough and overall weakening some, but still producing light precipitation. Focus for the next 48 hours will be a 500 mb low in central Saskatchewan and short wave trough southeast into central ND at 08z. Temps while cool ahead of it where clouds are thinner, as clouds thicken in advance of trough temps do warm with temps and dew pts above 32F so not anticipating any wintry issues. This weekend will see upper ridge builds in briefly behind the departing 500 mb low.
451 AM MDT Thu Oct 30 2025 - Highs about 5 degrees cooler today behind the cold front.
636 AM CDT Thu Oct 30 2025 Updated at 619 AM CDT Thu Oct 30 2025 - Freezing temperatures and frost are expected this morning across much of central and western Oklahoma and into western north Texas with temperatures as low as 27 degrees.
High pressure will dominate the weather across northern Arizona over the coming week. Most locations will see warming daytime temperatures heading into the weekend as high pressure builds.
529 AM CDT Thu Oct 30 2025 - Frost and freezing temperatures are developing west of US-281 this morning.
621 AM CDT Thu Oct 30 2025 Updated at 620 AM CDT Thu Oct 30 2025 - Sub-freezing temperatures this morning across portions of the Permian Basin and in the higher elevations.
The low producing the rain is tracking NE and rain is still expected to exit central Indiana by late this afternoon. Satellite shows clearing off to the west so expect high temps there near 60 this afternoon with highs in the low 50s for the east where rain is still ongoing. Wind gusts near 25 mph will continue into the afternoon but are expected to weaken slightly to 15-20 mph as the low and it's associated tighter pressure gradients progress eastward. Observational analysis shows low pressure over eastern Kentucky/Tennessee moving slowly northeastward. This rain is associated with the back-edge of the departing low pressure system. Further east where rain and clouds linger the longest, highs in the low 50s will be more common. Regardless, all areas will see breezy conditions today as the MSLP gradient around the low promotes frequent gusts between 20-30mph.
This could keep temperatures a few degrees cooler than forecast across our Panhandle and southeast Alabama counties but have left the current forecast in place with respect to temperatures. (Today and Tonight) A cooler airmass with breezy northwest winds will prevail today behind a cold front. Some upper 30s are possible in the normally cooler locations.
Increasing clouds this afternoon and a weak cold advection signal in the 850-700 mb layer will contribute to cooler highs this afternoon, averaging about 5 degrees colder in the lower elevations. The influencing 500mb ridge over the region Today is forecast to shift into the Lower Great Basin and Northern Rockies regions as the flow becomes more zonal by midday Friday as the flow responds to and approving atmospheric river moving toward the NW Pac.
- Wind chills will be in the low-to-mid-30s around trick-or- treat time so please ensure you and your family are prepared for the colder temperatures.
- Warmer, above normal temperatures over the weekend.
Winds will stay light and below 6 kts as high pressure ridging stays in control. Increasing clouds this afternoon and a weak cold advection signal in the 850-700 mb layer will contribute to cooler highs this afternoon, averaging about 5 degrees colder in the lower elevations. The influencing 500mb ridge over the region Today is forecast to shift into the Lower Great Basin and Northern Rockies regions as the flow becomes more zonal by midday Friday as the flow responds to and approving atmospheric river moving toward the NW Pac.
1107 AM MDT Thu Oct 30 2025 - Highs about 5 degrees cooler today behind the cold front.

1207 PM CDT Thu Oct 30 2025 Updated at 1207 PM CDT Thu Oct 30 2025 - Freezing temperatures and frost are expected this morning across much of central and western Oklahoma and into western north Texas with temperatures as low as 27 degrees.
Have SPS out for this into early afternoon, though with air temperatures now above freezing, threat of any icy conditions has ended.
- Cooler than normal temperatures for several days. During Halloween candy prime time, it will be quite cool with temperatures in the low to mid 50s (mid to upper 40s on the Plateau). (Friday Night through next Thursday) Cooler than normal temperatures are expected through this weekend. We continue to have some uncertainty in the forecast with the impacts from an upper level low pressure system that will drift over the region this weekend, particularly with timing and amounts of rain showers.
1205 PM CDT Thu Oct 30 2025 - Temperatures will fall to the low 40s degrees across the area with some locations dipping into the 30s.
Tomorrow will see cool weather continue, as weak cold front pushes into the plains during the morning hours. As we get into the weekend, a broad upper ridge is expected to dominate the pattern, with Colorado sitting on the northeastern edge of the ridge.
The initial trough, which prompted this pattern shift continues to progress through the OH valley. Light winds and clear skies will promote maximum radiational cooling with lows in the low to mid 30s. Much of central KS spent several hours below freezing this morning, therefore no additional frost or freeze headlines are expected for the remainder of this year.
236 PM EDT Thu Oct 30 2025 Low pressure exits to the north on Friday morning, but unsettled weather will continue with gusty west winds and scattered rain showers. Low pressure will track over the region overnight and exit to our north Friday morning.

136 PM MDT Thu Oct 30 2025 - Breezy and colder tonight through Friday night behind a cold front. Further upstream, northwesterly flow gives way to upper level ridging across the Pacific NW.
-A strong cold front that pushed through the Florida Keys earlier today will support breezy to windy conditions. -The front will continue to usher in relatively cooler and drier conditions, lasting through the end of the work week. A strong cold front pushed thorugh the Florida Keys earlier today. From synopsis, fresh to strong northwesterly breezes will continue this afternoon in the wake of a cold front that pushed through the Keys marine zones earlier this morning. High pressure will build in behind the front as it moves along the Gulf towards the western Atlantic. A developing low pressure system over the southeast U.
Temperatures are not expected to change much this afternoon, however tonight with cooler air working in and a decrease in cloud cover temperatures will likely drop down into the 30s in most locations.
- Light winds are expected around Trick-or-Treat time, but will be enough to reduce wind chills to the low to mid 30s deg F.
- Breezy and mostly dry behind a cold front today, with hazardous boating conditions across the coastal waters and a High Risk of rip currents at area beaches.
Then models push the higher RH values east. Some weak warm air advection ahead of a weak approaching trough axis aloft is shown in guidance as well. This could help keep temperatures a bit warmer in portions of NW Alabama.
(This evening through Friday night) After a cold start with most of the Panhandles well below freezing, sunny skies with temperatures well into the 60s are present this afternoon as of the latest 18Z obs. Sub freezing low temperature tonight and tomorrow night are expected for the northern and western Panhandles.
Updated at 103 PM CDT Thu Oct 30 2025 - The passage of a strong cold front brings the coldest air so far this season for the latter half of the week. High pressure will build across the area in the wake of a departing cold front.
- Much cooler and drier air arrives today and continues into the weekend. In the wake of the recent cold front, breezy northwest winds across the forecast area are advecting in cooler and drier temperatures. This cool air blowing across relatively warmer Gulf waters is producing some clouds and light showers, and coastal areas could see some brief periods or light rain through the rest of the day. The high risk of rip currents will also continue through Friday as breezy winds brings surf onshore. Temperatures will then moderate slightly through the weekend under sunny skies as high pressure builds in from the north.
A weak upper level disturbance over Iowa and the WAA wing of the approaching upper level low near the Manitoba/Saskatchewan/North Dakota border area has produced a band of low and mid level clouds across Minnesota. The upper low will continue southeastward to southeast ND by early Friday morning and southeastern MN by Friday evening. As for snow potential, wetbulb zero heights are generally above 1500 ft AGL, but may drop to around 1000 ft AGL under the low center in the late afternoon and early evening.
151 PM EDT Thu Oct 30 2025 Clearing skies and breezy winds expected today behind a cold front.
Updated at 1225 PM CDT Thu Oct 30 2025 - Red Flag Warning valid through 10 PM CDT tonight - Another cooler morning in store Friday morning.
222 PM CDT Thu Oct 30 2025 - Frost advisory in effect tonight for areas across east central and northeast Kansas that have yet to experience freezing conditions.
Today through Friday Morning: Dry conditions with light winds will prevail through tomorrow morning as a ridge of high pressure sits overtop the PacNW.
- Much cooler and drier air continues into the weekend. Early evening IR satellite and radar imagery is showing cloudy skies and some light rain continuing to stream southeast across the eastern Gulf waters as cool air advects across relatively warmer surface waters. Otherwise, the high risk of rip currents will continue through the day on Friday. Northwest winds of 20 to 25 knots behind the recent cold front are producing elevated seas and triggering Small Craft Advisory level headlines through early Friday morning as winds and seas slowly subside.
808 PM CDT Thu Oct 30 2025 Updated at 614 PM CDT Thu Oct 30 2025 - Red Flag Warning valid through 10 PM CDT tonight - Another cooler morning in store Friday morning.
735 PM EDT Thu Oct 30 2025 - Breezy and mostly dry behind a cold front today, with hazardous boating conditions across the coastal waters and a High Risk of rip currents at area beaches.
A high cloud shield associated with a weak upper ridge will work east of the area overnight. Looking at low temperatures similar to Thursday morning if not a few degrees warmer thanks to the clouds. Friday starts off clear for most sites, but clouds will be quick to increase as further ridging builds in from the coast.
Upper Michigan remains under the influence of a low amplitude upper level ridge which extends from the Ozarks region over Lake Superior and northern Ontario this afternoon. Low clouds and fog were stubborn to erode across the west today given the low sun angle, but have largely dissipated with daytime heating per the latest observations and visible satellite imagery. Meanwhile, a diffuse upper level trough with several embedded vort maxes resides just east of the area, extending from Hudson Bay down through eastern Ontario and into the Ohio River Valley. These two features will merge into one longwave trough encompassing the Great Lakes region by Friday as the upstream low dives southeast into Minnesota tonight, bringing about a change to a more showery regime across the U.
Muscha (This evening through Friday night) After a cold start with most of the Panhandles well below freezing, sunny skies with temperatures well into the 60s are present this afternoon as of the latest 18Z obs. Sub freezing low temperature tonight and tomorrow night are expected for the northern and western Panhandles.
818 PM EDT Thu Oct 30 2025 Low pressure will strengthen while tracking from the northern Middle Atlantic to Atlantic Canada through Friday.
526 PM MDT Thu Oct 30 2025 - Breezy and colder tonight through Friday night behind a cold front. Further upstream, northwesterly flow gives way to upper level ridging across the Pacific NW.
Today has been another seasonable and sunny fall day while a dry airmass remains in place, and ridging persists over the West. This overnight warmup will keep valleys that have not yet experienced a hard freeze above freezing temperatures tonight. Stronger afternoon wind gusts are possible tomorrow, especially over the higher terrain, as stronger winds aloft move across our region.
A large-scale ridge containing well above normal 500 mb hghts will persist over our area deep into this forecast period.
621 PM CDT Thu Oct 30 2025 - Temperatures will fall to the low 40s degrees across the area with some locations dipping into the 30s.
538 PM CDT Thu Oct 30 2025 - Frost advisory in effect tonight for areas across east central and northeast Kansas that have yet to experience freezing conditions.
624 PM CDT Thu Oct 30 2025 Updated at 621 PM CDT Thu Oct 30 2025 - The passage of a strong cold front brings the coldest air so far this season for the latter half of the week. High pressure will build across the area in the wake of a departing cold front.
741 PM EDT Thu Oct 30 2025 Low pressure exits to the north on Friday morning, but unsettled weather will continue with gusty west winds and scattered rain showers. Low pressure will track over the region overnight and exit to our north Friday morning.
730 PM EDT Thu Oct 30 2025 Dry high pressure will build into the area this weekend.
-Winds will continue to relax overnight in wake of yesterday's cold front. -Relatively cooler and drier conditions will last through the end of the work week. Somewhat cooler, but drier air, continues to filter down across the Keys in wake of this mornings cold frontal passage. While temperatures are near to slightly above seasonal norms, dew points have fallen into the lower 60s. Through the overnight period, the combined effect of the Gulf ridge consolidating over Texas and Melissa pulling further away will result in a continued downward wind trend across the Keys. The pressure gradient across Keys waters will continue to relax as modest high pressure consolidates over Texas and Hurricane Melissa lifts further out and away from Florida.
- Temperatures will fall to the low 40s degrees across the area with some locations dipping into the 30s. - Cold front on Saturday bringing low chance for rain showers to our eastern counties. The most consequential outcome of this trough will be a very low chance for isolated showers late tonight into Saturday. Highs today will be a few degrees warmer than yesterday overall with readings hitting the mid to upper 70s, and lows Saturday morning will drop into the low to mid 40s.
Tonight's short wave is the first of several to pass through this weekend, as the upper low drops south into the Great Lakes through Saturday. The clouds will keep the diurnal range limited, but cool, with lows in the lower to mid 30s and highs in the mid 40s to around 50.
Thermometers are falling through the low/mid 40s in most places early this morning under variable cloud cover, with the coldest western valleys dropping into the upper 30s. The latest weather analysis shows eastern Kentucky positioned between a departing storm system, a 988 mb low centered over Southern New England, and a high-pressure ridge extending from Montana to Texas. Aloft, broad 500 hPa troughing is in place over the Eastern CONUS, while a ridge axis extends from the Pacific Northwest northward into Northwestern Canada. Mostly clear skies will follow tonight with temperatures dipping back into the lower and middle 30s, allowing for frost to form in valleys and low-lying areas.
221 AM EDT Fri Oct 31 2025 Low pressure exits to the north on Friday morning, but unsettled weather will continue with gusty west winds and scattered rain showers. Low pressure will track over the region overnight and exit to our north Friday morning. Temperatures may get cold enough for some wet snowflakes to mix in across some of the higher elevations and northern Oneida County Saturday night.
-Rain chances are set to return Saturday ahead of a cold front.
1037 PM CDT Thu Oct 30 2025 Updated at 1035 PM CDT Thu Oct 30 2025 - A weak cold front Friday will bring cooler temperatures by Saturday with a low chance for light rain showers across southeast Oklahoma and into north Texas. (Rest of today and tonight) Light winds and sunny skies this afternoon will help temperatures get up to the low 60s across much of the area. A mid-level trough will move further to the south across the Plains on Saturday.
-Winds will continue to relax today in the wake of yesterday's cold front. -Relatively cooler and drier conditions will continue for Friday. Lastly, we continue to relish in the lower, more comfortable dew points of lower to mid 60s. High pressure is moving in behind the front and will skirt eastward across the Gulf and into the Southeast U.
- Much cooler and drier air continues into the weekend. A closed upper low has moved northeastward and is now located over the eastern Great Lakes, while broad upper troughing remains over the eastern half of the CONUS. On the surface, a deep low pressure system is located over the New England region with the associated cold front extending southward through the western Atlantic. Closer to Florida, a 1020 MB high pressure center is located near TX/LA and will ridge eastward across Florida to produce pleasant and much cooler weather to close out the work week. This pleasant and cooler weather will continue into the weekend as this high pressure center tracks east-northeastward through the southeast U.
A weak upper level disturbance over Iowa and the WAA wing of the approaching upper level low near the Manitoba/Saskatchewan/North Dakota border area has produced a band of low and mid level clouds across Minnesota. The upper low will continue southeastward to southeast ND by early Friday morning and southeastern MN by Friday evening. As for snow potential, wetbulb zero heights are generally above 1500 ft AGL, but may drop to around 1000 ft AGL under the low center in the late afternoon and early evening. Clouds will remain, however, making for another gray and cool day with highs in the low to mid 40s.
This in turn will keep the temperatures below normal with overnight lows near to just below freezing for large swaths of the panhandles.
