508 PM MDT Tue Oct 28 2025 - Chilly today with temperatures struggling to reach the lower 40s. - High pressure brings moderating temperatures through the rest of the week, with highs in the 50s and 60s. The H5 trough is quickly departing to the east taking cloud cover and precip with it. Cold temperatures will remain entrenched across the state, keeping temperatures much cooler than we've seen recently, only reaching the lower 40s for most areas. The rest of this week will be dominated by the building H5 ridge across the Rockies.
628 PM CDT Tue Oct 28 2025 Updated at 610 PM CDT Tue Oct 28 2025 - A cold front will bring widespread rain to the Mid-South through Wednesday night.
852 PM MDT Tue Oct 28 2025 - High pressure brings moderating temperatures through the rest of the week, with highs in the 50s and 60s. The H5 trough is quickly departing to the east taking cloud cover and precip with it. Cold temperatures will remain entrenched across the state, keeping temperatures much cooler than we've seen recently, only reaching the lower 40s for most areas. The rest of this week will be dominated by the building H5 ridge across the Rockies.
- Freezing temperatures return to our low valleys tonight into tomorrow morning. - Temperatures begin to recover Wednesday and beyond thanks to high pressure and light winds. As such, overnight low temperatures will be near or below freezing for much of the region, including some areas where hard freezes have not yet occurred. High pressure will support warming temperatures over the next few days, so tomorrow's highs will be around 5 to 10 degrees warmer than today's.
Rain chances will remain high tomorrow as the low becomes stacked over Middle TN but the rain should be more showery by the evening. (Rest of today through Wednesday) Low clouds along with patchy drizzle and fog lingered this Tuesday morning as an upper level low pressure system departed to the east. Southeast wind gusts will peak near 30 mph at times Wednesday morning as the low center moves into the Mid State. Lows tonight will be in the upper 40s to lower 50s with highs Wednesday in the lower to mid 50s. Temps will fall to the low to mid 40s.
-A cold front will usher in relatively cooler, drier, and breezy conditions for the middle of the week. However, there may be some lingering effects over the next few hours due to a confluent zone setting up across our area, between Melissa to our southeast and ridging across the Gulf. As Melissa lifts further northeast, weak high pressure will be shoved southeastward closer to the Keys by a cold front advancing across the northwestern Gulf. This will both push the confluence zone out into the Straits and let surface dew points drift downwards into the lower to mid 70s. Meanwhile, ridging over the Gulf will result in modest freshening of northerly flow through the overnight period.
443 PM MDT Tue Oct 28 2025 - Continued sub-freezing low temperatures for most locations tonight. - Warming afternoon highs, exceeding 60 degrees in the lower elevations by the weekend.
634 PM CDT Tue Oct 28 2025 Updated at 625 PM CDT Tue Oct 28 2025 - The passage of a strong cold front midweek brings the coldest air so far this season the latter half of the week.
720 PM MDT Tue Oct 28 2025 - Hard freeze expected for all of the lower elevations Tuesday night.
701 PM CDT Tue Oct 28 2025 - Cold front moves across the region today brining widespread light to moderate rainfall.
(Rest of today and tonight) The H250 and H500 jet maxims have reached the panhandles and will continue to dig on the back side of the upper trough axis, which is centered over the western plains. The deepening trough becomes a closed low tonight while tracking southeastward across the KS/MO/OK/AR junction and the LLJ intensifies to near 65 knots while traversing Oklahoma beginning early Wednesday morning. While air temperatures are not expected to reach freezing tonight, the strong winds and cold temperatures could lead to wind chill values in the 20's and 30's overnight and into Wednesday morning. Cooler temperatures will be seen on Wednesday with highs in the 50's and 60's.
-A Wind Advisory is in effect for the entire state of Arkansas through this evening for sustained winds of 25 mph and wind gusts which will exceed 35 mph, possibly 40 mph in the higher terrain across Arkansas. -Below average temperatures are anticipated through the most of the forecast period due to the combination of wet weather, cloud cover, and the passage of a cold front.
The surface pressure gradient will remain tight across our area today as a low pressure system passes to the north of the region across the Arklatex.
As the low deepens tonight it will bring breezy southern winds gusting up to 30 mph and will increase our warm air advection. Lows tonight will fall into the upper 40s to lower 50s and with the rain and clouds we won't warm much during the day Wednesday with highs only in the low to mid 50s. The upper level low will remain over Middle TN into Wednesday night and that will keep showers in the forecast. Colder air will slowly start to push in dropping lows into the low to mid 40s. The upper level low will be lifting into the Northeast early Thursday with breezy northwest winds kicking in, gusts up to 25 mph.
- Warmer temperatures return by the weekend. (Today and tonight) Winds have significantly diminished from their peak yesterday afternoon, however this will allow for cooler overnight lows particularly on the Caprock. A Freeze Warning remains in effect from 2 AM to 10 AM, with lows falling into the low 20s. Winds will diminish into the evening as the upper low responsible in part for the cold airmass will depart northeastward.
235 AM MDT Wed Oct 29 2025 - Cold front brings breezy conditions to the area today through Thursday.
The strongest core of the low- level jet will push south out of the area through the afternoon with a relaxation in the highest wind gusts. This morning's low temperatures will not quite reach freezing, however breezy winds this morning will give way to brisk wind chills in the 20s to 30s across the area.
152 AM EDT Wed Oct 29 2025 An upper low will move across the region through Thursday, bringing rain to the Ohio Valley.
Low pressure near the Missouri Bootheel being driven by a closed low aloft, is bringing widespread rain to the region this morning. The ending of the precip over the rest of the area will be slower, depending more on the slow eastward progression of the low through the afternoon as moisture continues wrap back into east central and southeast Missouri as well as southern Illinois. Carney The long wave pattern remains amplified across the CONUS with ridging over the west and troughing over the east. The trough over the eastern US will keep the Mid Mississippi Valley in northwest flow for the majority of the period.
LREF probabilities of temperatures cooler than 37 Thursday morning are highest for location north of the KC metro and west of this line. Farther south and east, will need to keep an eye on the potential for fog developing if the low level moisture from the recent rainfall is not given ample opportunity to mixout.
- A strong cold front will move through the region tonight and bring the next best chance for rain. - Strong gusty winds are expected Wednesday in the wake of the cold front. We will be in a post frontal regime today on the backside of an upper low.
High pressure will dominate the weather across Arizona. Light winds across the valleys of northeast Arizona and longer nights will combine with the dry air mass to drop temperatures below freezing, especially for portions of the Little Colorado Valley and Chinle Valley.
1218 AM CDT Wed Oct 29 2025 Freezing temperatures begin tonight for the Oklahoma Panhandle and a large portion of the Texas Panhandle.
1217 AM PDT Wed Oct 29 2025 Updated at 1217 AM PDT Wed Oct 29 2025 * Dry and fair weather thru this weekend under high pressure The current forecast is on track.
Broad upper level ridging is draped across eastern Ontario, northern Quebec, and the Upper Great Lakes. This is working to block an upstream trough and cold front over the Plains, thereby keeping Upper Michigan dry.
- Seasonably cool afternoon temperatures continue through the work week, with sub-freezing low temperatures in central Kansas tonight. But as the low moves further east this afternoon, the pressure gradient across the region will relax and the winds will begin to subside. This morning, with the low lingering to our east, we could also have a few pesky showers continue to impact eastern Kansas through the morning hours. As the low slowly drifts east into the Tennessee Valley this afternoon and into tonight, the showers will come to an end for southeast Kansas.
- Quiet and cooler through mid-late week, with those planning Halloween activities needing to plan for chilly conditions in the 40s.
Eastern Iowa has been slowly saturating as dry easterly flow from the Great Lakes high pressure is still having an influence over that portion of the state. Upper low pressure responsible for the precipitation is over eastern Kansas and Nebraska and will continue to dig south and deepen tonight and will be near the Arkansas/Louisiana area by Wednesday morning. As this occurs, another upper low moving eastward under the upper high in Canada, will get caught up into the cyclonic flow of the main system and will result in cyclonic flow originating from Lake Superior through Wednesday. High precipitation chances will persist through much of tonight then will be diminishing from north to south as the upper low settles south and mid-level subsidence and drying occur.
142 AM EDT Wed Oct 29 2025 High pressure north of New England will continue mostly dry weather Thursday morning.
(This evening through Wednesday) Early this afternoon, a strong cold front was located from Sonora northeastward to San Saba as it was pushing southeastward into the Hill Country. The upper-level trough that is driving this cold front southward will move into the ArkLaTex by tomorrow morning.
159 AM MDT Wed Oct 29 2025 - Continued sub-freezing low temperatures for most locations tonight. - Warming afternoon highs, exceeding 60 degrees in the lower elevations by the weekend.
Updated at 130 AM CDT Wed Oct 29 2025 - Sub-freezing temperatures expected this morning and Thursday morning across portions of the Permian Basin and in the higher elevations.
We have once again lowered POPs through Thursday as it appears the rain will stay just east or graze the extreme eastern zones as low pressure tracks into the interior northeast U. Model agreement and continuity has been good with the track of the low over the past couple days so we are confident with continuing the forecast of lower chance POPs of 20 to 30 percent in that area and dry elsewhere.
- The passage of a strong cold front brings the coldest air so far this season for the latter half of the week.
Issued 359 AM CDT Wed Oct 29 2025 Today through Thursday: Low pressure will remain well to the south and southeast of the region during this period, with weak high pressure moving through the area later tonight into Thursday. Cyclonic flow at 500 mb should linger through tonight over the area, until the 500 mb low shifts well to the east, with a weak 500 mb ridge axis shifting across the area on Thursday. The low level moisture is in question, so not sure if any lake effect showers may occur.
- Cooler with shower chances returning to end the week into the weekend. High pressure remains in control across the Great Lakes, maintaining quiet conditions across the region. High pressure remains the dominant feature through midweek, maintaining dry and seasonably mild conditions into at least part of Thursday.
Low pressure moves northeast of the FA across the Appalachian Mountains on Thursday with any lingering rain showers diminishing quickly in the morning.
Early this morning water vapor imagery and model height analysis showed an upper level high pressure over Quebec with an upper low retrograding westwards over the eastern Great Lakes, resembling a rex block. High temperatures today will be a few degrees cooler than yesterday, mainly the low 50s, which is still about 5 degrees above average.
1055 PM MDT Tue Oct 28 2025 - Chilly temperatures expected into Wednesday morning behind a cold front. - Warmer temperatures return late this week and for the weekend. A chilly and breezy day continues across the area as an upper-level trough sits over the forecast area. Current temperatures are in the 30s and 40s and are not expected to get much warmer than that. The upper- level trough will exit tonight, weakening winds across the area. Upper-level ridging begins to build over much of western CONUS on Wednesday. Subsidence under the ridge will keep skies mostly clear with no chance for precipitation. Thursday starts with ridging flattening out as a low in Central Canada sweeps a trough to our north with a dry cold front having just passed across the region to start the day.
- A clipper system will bring breezy winds on Thursday and cooler temperatures on Halloween. Weak upper level flow aloft continues across the Northern Plains as ridging builds out over Western CONUS. Tonight overnight low temperatures are forecast to drop into the lower 20s maybe even dropping down into the upper teens in the southwest early tomorrow morning. An upper level ridge will pass overhead tomorrow leading to a very subtle warm up out west. The upper level ridge will quickly pass with an upper low moving through the region Thursday with breezy conditions from a cold frontal passage. This upper low could bring light precipitation to the region including a rain snow mix depending on the timing of the wave.
Deepening upper low will move into the TN valley today. Highs today remain well below normal, though a few southern or eastern locales could touch the low 60s for a short time.
941 PM MDT Tue Oct 28 2025 - High pressure brings moderating temperatures through the rest of the week, with highs in the 50s and 60s. The H5 trough is quickly departing to the east taking cloud cover and precip with it. Cold temperatures will remain entrenched across the state, keeping temperatures much cooler than we've seen recently, only reaching the lower 40s for most areas. The rest of this week will be dominated by the building H5 ridge across the Rockies.
- Much cooler and drier air arrives Thursday and continues into the weekend. A strong cold front however will be approaching from the northwest during the day so the rather light winds early in the day will shift to southwest to west and increase as the front approaches later today. Behind the front breezy northwesterly winds will usher in much cooler drier air, but this cool air moving over the relatively warm gulf waters could lead to a few light showers/sprinkles moving onshore during Thursday.
Closer to home, radar mosaics show light rain and/or drizzle across the area with the higher returns and subsequent higher rainfall occurring over northeast IA extending southeast towards Sterling/Rock Falls. lingering light rain/drizzle will continue but diminish from northeast to southwest over the next 3-6 hours as the aforementioned upper low tracks across Arkansas.
Updated at 1129 PM CDT Tue Oct 28 2025 - A cold front will bring widespread rain to the Mid-South through Wednesday night.
- Weak cold front on Thursday will bring breezy conditions. In the wake of the exiting upper level trough we are seeing subsidence move into the region and breezy north to northwest winds impacting much of eastern Wyoming and western South Dakota. As an upper level ridge brings increasing heights into the region, expect the winds to diminish this evening, but with the expected mostly clear skies and light to calm winds, temperatures will crash across the region tonight. Overnight lows are forecast to drop into the 20s for most areas with those sheltered valleys and typical cold spots seeing temperatures drop into the teens tonight! The aforementioned upper level ridge will be the main weather driver and bring dry conditions and temperatures should moderate underneath this ridge.
1237 AM CDT Wed Oct 29 2025 - Cold front moves across the region today brining widespread light to moderate rainfall.
Clearing skies are expected through the morning hours as the high cirrus shifts south of the area. For Halloween, the late afternoon into early evening timeframe will feature temperatures in the lower 50s which will steadily fall into the mid-upper 40s after sunset.
1112 PM CDT Tue Oct 28 2025 - Strong winds continue this afternoon - Freeze Warning in effect late tonight into Wednesday morning - Another freeze Wednesday night into Thursday morning 19z 500 mb analysis depicts a trough sweeping southward across the Plains with the strongest flow on its western flank, which is moving across the forecast area this afternoon. However, NBM probabilities for temperatures below 32 degrees remains high for much of the CWA, including a 40-70% chance of falling below freezing along the Oklahoma Panhandle and Kansas border. Lesser probabilities farther north and east from there given the winds, but Freeze Warning still featured given some chance for parts of the county reaching freezing, especially if winds can be weaker.
So overall looking at a sunny day and winds light as high pressure moves into the Red River valley 21z. This high moves east tonight as winds turn south and increase to 10 kts in DVL basin after 06z Thu.
29 inches per 00z DTX raob) will maintain one more dry day, despite the upper level low backing in from New York and moving over the Central Great Lakes by day's end. With some moistening and cooling of the low levels, along with some low cloud development, should end up slightly cooler today compared to yesterday.
- A very weak cold front sweeps through tonight, bringing slightly cooler temperatures for Thursday.
As the low deepens, it will bring breezy southern winds gusting up to 30 mph and will increase our warm air advection. Lows tonight will fall into the upper 40s to lower 50s and with the rain and clouds we won't warm much during the day Wednesday with highs only in the low to mid 50s. The upper level low will remain over Middle TN into Wednesday night and that will keep showers in the forecast. Colder air will slowly start to push in dropping lows into the low to mid 40s. The upper level low will be lifting into the Northeast early Thursday with breezy northwest winds kicking in, gusts up to 25 mph.
It will edge east slowly High pressure will be over the RRV this aftn and with that light winds under 10 mph during the day for all. So overall looking at a sunny day and winds light as high pressure moves into the Red River valley 21z. This high moves east tonight as winds turn south and increase to 10 kts in DVL basin after 06z Thu.

656 AM CDT Wed Oct 29 2025 - A strong cold front is moving through the region with light rain showers possible through the afternoon. - Strong gusty winds continue today in the wake of the cold front. We will be in a post frontal regime today on the backside of an upper low.
Early this morning a weak cold front has moved through the region and become a stationary front stretching across southern AZ. This stationary front will cause wind gusts to pick up later this morning across southern and south-central AZ and the Lower CO River Valley. Hi-res guidance continues to show the potential for wind gusts above 40 mph across the higher terrain in eastern AZ. Hi-res guidance even shows the potential for gusts up near 50 mph along the highest ridgetops. Elsewhere, wind gusts of 25-35 mph are expected across SW AZ and the lower CO River Valley and gusts of 20- 30 mph expected across south-central AZ (including the Phoenix Metro). With these H5 heights temperatures this afternoon will be very similar to yesterday with most lower desert locations seeing highs in the lower 90s.
- Warmer temperatures return late this week and for the weekend. Dry and benign weather mid to late this week as a transient upper level ridge axis quickly move into the area today and southeast of the area by tonight. Models continue to indicate a weak cold front moving southeast across the plains Wednesday night, but no precipitation is expected at this time with dry FROPA.
An upper level ridge continues to dominate the synoptic pattern over central California, leading to a warming trend that will continue through much of the week.

-A cold front will usher in relatively cooler, drier, and breezy conditions through the end of the week. While ridging is across the Gulf and Hurricane Melissa is to our southeast we continue to be in a confluent zone resulting in the seen convection on KBYX and our overnight activity. Throughout today, Melissa will continue to move farther northeast resulting in high pressure being pushed southeast closer the Keys from a cold front moving in. From synopsis, the Florida Keys remain in between features, as weak ridging builds in over the Gulf and Major Hurricane Melissa slowly treks north northeastward off of Jamaica and towards eastern Cuba.
- A deep low pressure system will continue to produce light showers in the north through this afternoon. Although the cold front has pushed well east of the area, the nearly stacked low pressure system over north Mississippi will move slowly to the east southeast today. /22/ We will be in a post frontal regime today on the backside of an upper low.
314 AM PDT Wed Oct 29 2025 High pressure aloft and weakening offshore flow will bring high temperatures as much as 15 to 20 degrees above average today for portions of the valleys and inland coastal areas with dense fog near the coast early this morning.
