952 PM PDT Sun Oct 5 2025 * Dry conditions with a warming trend are expected through midweek as high pressure builds across the region. * Weather at the end of the week may become wet and unsettled as a tropical system interacts with an upper-level trough moving into the West Coast. Quiet weather is expected in the near term as high pressure gradually builds over the region.
306 AM CDT Mon Oct 6 2025 - Freezing temperatures are possible again tonight across western and northern parts of the state. Currently there is quasi-zonal flow across North Dakota at the bottom of a large trough. Moving on shore in the Pacific Northwest, is a large ridge. At the surface a strong high pressure center, located in eastern Montana, is influencing the Northern Plains. The lowest temperatures are occurring in far northwestern North Dakota, but freezing temperatures are possible across the state. For western and central North Dakota, a Freezing Warning is on going.
- Cooler temperatures carryover into early Tuesday with patchy frost possible over the western Sandhills. Precipitation should clear out by early afternoon as h5 trough axis clears and mid-level heights begin to climb. Temperatures today will remain on the cooler side, thanks to the precipitation and lingering cloud cover. Winds will remain light and variable as high pressure settles south into the area. aforementioned high pressure will stall over central Nebraska, lingering through the overnight. Longwave troughing over Hudson Bay will continue to depart to the east. Low-amplitude ridging will fill in over the High Plains as a result. Dry to mostly dry conditions are likely as upper-level high pressure expands its influence north into the Central Plains.
- Cooler temperatures arrive tonight, with patchy frost possible Tuesday night in western Wisconsin.
(Today through Tuesday) The large scale pattern across the region remains mostly unchanged today, with a ridge of high pressure building over the southeast CONUS. The interaction between the ridge and the low will continue to maintain an enhanced pressure gradient across the region, but with the low drifting south, so will the pressure gradient, thus supporting moderate to fresh easterly flow through the short term. Overnight temps could dip to the low to mid 70s over the interior, and warmer upper 70s along the East Coast.
245 AM CDT Mon Oct 6 2025 - A cold front will bring showers and a few thunderstorms to central Illinois today into tomorrow evening. - Brief dip in the temperatures to near normal (normal highs: low 70s, normal lows: upper 40s) midweek behind the cold frontal passage, before warming back into the 80s during the day for the weekend. The pressure gradient relaxes today, leaving us with much calmer winds than yesterday, as the cold front progresses eastward. Increased moisture advection from the south ahead of the cold frontal passage will bring a chance for precipitation to southeastern IL this afternoon. Timing for this cold front shows it entering the northwestern counties of the CWA by this evening (~00z). Showers and thunderstorms will accompany the cold frontal passage, lingering into Tuesday.
- A cold front brings cooler temperatures on Tuesday. (Through Monday) Showers and a few thunderstorms are ongoing across portions of the panhandles into Kansas associated with a cold front making its way slowly south and eastward.
Water vapor satellite imagery shows broad trough draped over the Northern Rockies today. Any additional snow that falls today should remain light and close to ridge tops, but a few stronger showers could briefly drop snow levels to pass level and higher elevation communities like Island Park. Clearing overnight along with northerly flow will drop overnight lows to freezing or below.
At the surface a cold front will continue to move slowly southeast through the region. These are expected to intensify slightly and become more numerous as the cold front moves through this area. Highs in general will be cooler today thanks to the cloud cover and the northwesterly winds behind the front. Tonight the cold front continues to push southeast of the region but it's progression slows significantly. Lows will be around seasonal averages in the low 40s. Grassland fire danger will be low, due to the cooler temperatures, higher relative humidity values (40-55%) and northerly winds becoming light. Tuesday an upper ridge moves over the northern Plains with high pressure at the surface.
207 AM EDT Mon Oct 6 2025 High pressure east of the region will bring another mostly sunny and warm day on Monday.
Near to slightly above normal temperatures are expected early this week with ridging in place. The next significant chance of rain comes mid-week as a cold front moves through the forecast area, followed by a reinforcing shot of cooler and dry air to end the week. A mix of sun and clouds is expected and should allow temperatures to rise back into the lower 80s today. The upper ridge flattens out on Tuesday in response to a sharp trough digging into the Great Lakes. Expect highs to reach the lower to mid 80s, slightly above seasonal values.
Much warmer than normal conditions will continue Monday especially along the coast where highs could reach the mid 70s. Over the past 24 hours, broad high pressure has generally come to dominate over the area. This has allowed for clear skies and warmer than normal temperatures to return to the interior such conditions will continue Monday with highs most likely in the mid 80s for many interior valleys. A weak trough will gradually dip across the eastern Pacific through the week.
142 AM EDT Mon Oct 6 2025 High pressure remains in control through Tuesday.
The upper-level northerly wave continues eastward today as the ridge builds over to the PacNW tomorrow through Tuesday.
308 AM CDT Mon Oct 6 2025 - Cooler temps today and Tuesday with patchy frost possible Tuesday night in north-central Minnesota and western Wisconsin. Winds have also subsided based off of latest surface observations and are expected to stay relatively calm as high pressure builds in for the first half of this week. A trough axis move eastward along the international border throughout today. Highs in the low 60s and lows in the 40s to upper 30s.
A cold front is making it's way southeastward across the area this afternoon. Will have to monitor the low temperatures Monday night/Tuesday morning. As of now the lowest is 36 which would minimize the frost potential.
- A cold front, while initially stalling Monday morning across our northern counties, is expected to surge southward Monday night bring cooler weather on Tuesday.
- Much cooler temperatures Monday, with highs in the upper 50s to low 60s. Rest of this afternoon through tonight: Widely scattered, high-based showers are ongoing across portions of eastern NE as of 2 PM, with that activity occurring ahead of a cold front which has moved into northeast NE. Latest CAM guidance indicates a gradual increase in shower and thunderstorm development late this afternoon into evening along and to the south of the cold front as the boundary layer continues to destabilize. The showers and thunderstorms are expected to evolve into a band across southeast NE and southwest IA this evening (PoPs increasing to 60-90%), along and ahead of the southward-moving cold front. Widespread clouds coupled with the influx of a cooler, Canadian air mass will result in highs only in the upper 50s to low 60s Monday afternoon.
Cooler than normal conditions will continue through midweek due to a broad area of upper-level low pressure over the West. A broad trough of low pressure remains over the western states this evening. Temperatures warmed to near normal today, but reinforcement of the trough tonight will likely bring some cooling for Monday and Tuesday. Conditions, typically cooler than normal will continue over the region into midweek along with night through morning low clouds and fog being a staple of the forecast. The low cloud field still looks pretty broken up this evening, but it is showing some signs of becoming more well-entrenched overnight. Some dynamics with the trough scrape the area tonight and into Monday.
211 AM EDT Mon Oct 6 2025 - Cold front brings rain by this evening - Frost/Freeze conditions for mid-week - Cold front brings rain this evening Height falls occur on today as the upper ridge shifts east with low level moisture increasing ahead of an advancing western CONUS trough, with deep moisture streaming up from the Gulf. A cold front is expected to focus showers and a few thunderstorms this evening into Tuesday morning. The front clears Lower Michigan on Tuesday night with dry northerly flow as high pressure builds in.
433 AM EDT Mon Oct 6 2025 High pressure centered east of the coast will maintain dry and warm conditions today. A passing cold front returns rain on Tuesday, followed by dry and cooler conditions the remainder of the week. KEY MESSAGES: - Dry and warm ---------------------------------------------------------------- Mostly sunny skies expected again as ridging remains the dominant feature.
200 AM CDT Mon Oct 6 2025 - Much colder today - Showery Tuesday morning and continued cool - Dry and warmer for the rest of the week A cold front has traversed about 70% of the FA early this morning.
Continue to exercise caution when swimming, especially near piers and jetties where rip currents have a higher probability of developing An upper level ridge will build into the region, bringing a generally rain-free week across the majority of the inland areas for Southeast Texas. Overnight lows will be in the low to mid 70s.
- Widespread below freezing temperatures again tonight into Tuesday morning.
355 AM CDT Mon Oct 6 2025 - Much cooler temperatures today with highs in the upper 50s as showers continue on-and-off through this evening. - Temperatures gradually trend warmer through the week with highs back in the 80s by this weekend.
Broad troughing from the past weekend will give way to southwesterly flow and building mid-level heights from a westward shifting ridge this week. By mid-week, the upper level pattern will be characterized by the aforementioned high centered over the southern plains and north- central Mexico, with a Pacific trough dropping south off the northwest coast.
638 AM CDT Mon Oct 6 2025 - Cooler temps today and Tuesday with patchy frost possible Tuesday night in north-central Minnesota and western Wisconsin. Winds have also subsided based off of latest surface observations and are expected to stay relatively calm as high pressure builds in for the first half of this week.

638 AM EDT Mon Oct 6 2025 High pressure dominates and continues the dry weather pattern with well above normal temperatures across the region through Monday.
Updated at 418 AM PDT Mon Oct 6 2025 - Warmer and drier conditions through midweek, with moderate offshore wind expected today and Tuesday in the higher elevations - Unsettled weather returns late this week (Today and tonight) A relatively weak offshore upper level low will slowly retrograde during the day today while maintaining a fetch of weak offshore flow that will tame the marine layer from making progress inland. With offshore flow today we'll see warmer than normal temperatures, with coastal communities feeling the biggest difference without much help from the marine layer.
736 AM EDT Mon Oct 6 2025 High pressure over the area today will move to the east on Tuesday.
An upper-level ridge of high pressure extends from the northeastern Pacific Ocean into the Pacific Northwest. Beneath the ridge, clear skies coupled with predominantly light winds and a dry air mass (PWATs of 0. Isolated near-freezing to freezing temperatures are expected (80% confidence) this morning for low-lying, cold- prone locations within the Yakima and Kittitas valleys, Columbia Basin, and along the Blue Mountain foothills; no Freeze Warnings have been issued due to limited spatial extent. Elsewhere, more widespread sub-freezing temperatures are expected (80-100% confidence) this morning for central Oregon, the John Day Basin, and the Grande Ronde and Wallowa valleys. By Tuesday, the ridge will flatten as a couple vort lobes drop south from the Gulf of Alaska and BC and carve out an offshore closed low.
These higher clouds should make for a beautiful sunrise without lower clouds blocking the view! Surface observations both along the island chain and on marine platforms are showing breezes out of the north to northeast near 5 knots, or 6 mph.
600 AM CDT Mon Oct 6 2025 - A cold front will bring showers and a few thunderstorms to central Illinois today into tomorrow evening. - Brief dip in the temperatures to near normal (normal highs: low 70s, normal lows: upper 40s) midweek behind the cold frontal passage, before warming back into the 80s during the day for the weekend.

632 AM EDT Mon Oct 6 2025 High pressure remains in control through Tuesday.
-Cooler air mass returns climatologically normal temperatures with overnight frost/freeze potential. The 12Z KAPX RAOB shows a decent near surface cap to overcome, however convective Ts of 80s will likely be reached over central parts of the lower peninsula. Most convective activity should remain showery with occasional thunder, with the low end chances for some marginally gust outflow winds. Midlevel troughing currently over central Canada will continue to progress eastward today and return an unstable air mass to the Great Lakes Region. A cold front parallel to midlevel heights will generate showers and even a few storms across the northwoods today. Overall conditions will be drying and turning quiet as high pressure returns a cool/Canadian air mass settles into the region.
500 AM CDT Mon Oct 6 2025 - Much colder today - Showery Tuesday morning and continued cool - Dry and warmer for the rest of the week A cold front has traversed about 70% of the FA early this morning.

A weak upper Atlantic ridge will build eastward over the Deep South and northern Gulf through Tuesday as the long wave trough passes over the Great Lakes and Ohio River Valley Tuesday night.
A cloud line is attempting to form over the Lower Keys at times producing light showers, therefore, VCSH is included at EYW. Aloft, a broad area of weak ridging remains centered over the Gulf, while a shallow trough and low level vorticity axis lingers to the east across the Bahamas. These higher clouds should make for a beautiful sunrise without lower clouds blocking the view! Surface observations both along the island chain and on marine platforms are showing breezes out of the north to northeast near 5 knots, or 6 mph.
1236 PM CDT Mon Oct 6 2025 - Cooler temps today and Tuesday with patchy frost possible Tuesday night in north-central Minnesota and western Wisconsin. Winds have also subsided based off of latest surface observations and are expected to stay relatively calm as high pressure builds in for the first half of this week. A trough axis move eastward along the international border throughout today. Highs in the low 60s and lows in the 40s to upper 30s.
The facts - an elongated trough will remain stretched across the SW United States for the next several days, before deepening toward the end of the week.
- Seasonal temperatures work into the area behind the cold front coming through today, lasting through the remainder of the work week. The cold front that is slowly passing through will still be over a portion of our area, with a weaker LLJ pumping into it. Best chances for the higher end of that range will largely be along a line from Freeport IL to Fairfield IA. This will allow for much cooler temperatures than we have been seeing, with most remaining in the mid-upper 60s. Guidance indicates some weak waves passing along the top of the building ridge.
