KEY MESSAGES: - Showers persist today, accompanied by below- average temperature --------------------------------------------------------------- A broad low-pressure system is centered north of central New York this morning.
With skies expected to remain cloudy longer, adjusted the low temperatures toward the warmer CONSShort. This resulted in low temperatures in the lower 30s west of the Mississippi River and in the lower and mid- 30s elsewhere. Even though the low temperatures will be warmer, not planning on making any changes to the Frost Advisory. These clouds could result in cooler high temperatures in these areas on Thursday. Thursday night Th 925 and 850 mb ridge build east across the area. Low temperatures will range from the lower 20s (maybe even a few upper teens in central Wisconsin) to the lower 30s.
141 AM PDT Thu Oct 23 2025 * A low pressure system centered over the region will move to the east by tomorrow. * A second trough of low pressure will move into the Pacific Northwest over the weekend, bringing minor impacts to the region.
155 AM EDT Thu Oct 23 2025 Low pressure over the Great Lakes will provide occasional showers, mainly across the north through Thursday. High pressure over weekend. Otherwise, upper low will slowly pull away from the Great Lakes region today. Winds will continue to be gusty once again today, but should generally start to slacken this evening as the low continues to pull away, and loss of heating/mixing. Friday looks to be continued cool, but dry, under the influence of high pressure.
1049 PM MDT Wed Oct 22 2025 - High pressure brings warming trend to afternoon highs, near normal lows, and light wind through Thursday night.
A ridge will remain over the region for the next several days with a warming trend through Friday, with mild temperatures during the day and cool temperatures at night.
1004 PM PDT Wed Oct 22 2025 * A low pressure system moving across the area today will bring cooler temperatures and a slight chance of precipitation to the southern Sierra and Great Basin. * After a brief lull Thursday and Friday, another trough of low pressure will move through the western U. over the weekend, bringing cooler conditions and breezy winds to the region.
104 AM MDT Thu Oct 23 2025 - High pressure brings warming trend to afternoon highs, near normal lows, and light wind through Friday.
The center of the closed upper low is slowly creeping east, and will continue that direction tonight and Thursday. However, a piece of energy is rotating around the upper low on the windward side and is headed towards the western Great Lakes region. Once the deeper moisture and more favorable lifting reaches eastern upper (later tomorrow morning) surface temperatures will already have warmed into the high 30s/low 40s. The added push from the passing wave will return the chances for small hail and graupel with the strongest cells, however the low topped nature should keep lightning mostly out of the picture. The larger upper level trough will finally begin to exit Friday, with heights aloft trending up. Global deterministic runs also have been showing run to run inconsistencies with how a large trough over the western CONUS continue east.
Much drier and slightly warmer weather returns for Friday and into the weekend.
Water vapor imagery currently shows a compact upper low tracking across Southern CA and about to move into the Desert Southwest. Meanwhile, a broad upper low remains positioned along the Ontario/Quebec border. We should see a gradual increase in high and mid clouds today as the upper low approaches from the west. By 00z Sat, upper low will be tracking over northeast NM and into the TX Panhandle by 18Z Sat.
1125 PM MDT Wed Oct 22 2025 - Mountain snow showers and scattered light rain showers in the lower elevations late Thursday into Friday.

1057 PM CDT Wed Oct 22 2025 - Freezing temperatures are expected overnight into Thursday morning at many locations. So, given the more favorable surface pattern tonight, this forecast update will lean heavily toward the low side of model guidance for overnight lows. Accordingly, the Freezing Warning will be expanded to include all of our southwest IA counties, as well as our Nebraska counties along and to the north of a David City to Omaha line.
305 AM EDT Thu Oct 23 2025 An upper trough will hang out over the Northeast through the end of the work week. That will mean seasonable temperatures and chances for showers, mainly during the day and over the higher terrain. Broad upper low over SE Canada slowly translates northeast today with cyclonic flow aloft persisting over the forecast area. Highs will range from the lows 50s north to low 60s near the coast. Forecast Details: Cool upper trof will remain overhead into the early part of the weekend. especially with diurnal heating under cool upper level temps and in the higher terrain where upsloping winds can assist lift. High pressure may allow for some valley fog to form. Broad low pressure remains north of the waters today through Friday.
A low pressure system will slide across the AZ/UT border today, leading to isolated showers and thunderstorms throughout the day across far northern AZ.
714 AM EDT Thu Oct 23 2025 A cooler and showery pattern will persist into the weekend, though additional precipitation totals will be mostly light. A large upper level low is slowly building into the region, bringing a cooler and showery pattern. Temperatures at the highest summits in the Adirondacks have fallen below freezing and they will likely remain there through this period. As colder air gradually works its way into the region heading into Friday, freezing levels will drop and the snow levels will drop into the Green Mountains and should reach some of the mid slopes.
- Near or below freezing temperatures this morning.
542 AM CDT Thu Oct 23 2025 - Freezing temperatures this morning at many locations. Clear skies and calm winds again this morning are allowing temperatures to fall even cooler than yesterday morning with many locations already in the 30 to 34 degree range. Highs right now forecast to stay in the low-to-mid 60s, but could see them get into the upper 60s in a few spots. Today we're watching a mid-level trough move out of California toward the I-70 corridor.

Friday looks to be continued cool, but dry, under the influence of high pressure.
- Widespread freezing temperatures tonight, mainly south of Highway 30. Additional headlines are possible for Friday night with temperatures dropping into the lower 30s across the entire forecast area. A strong upper jet streak rotating through large scale upper trough will keep western periphery of this upper level trough anchored across the southern Great Lakes today. Gusts should diminish sharply early this evening as a low level ridge axis builds in from the west.

Drier, warmer conditions will build into southwest Wyoming and Utah for the end week into the weekend.
Updated at 228 PM CDT Thu Oct 23 2025 - Low to moderate (20-40%) rain chances for the higher elevations into the Permian Basin today. - Medium rain chances(40-70%) for the Permian Basin and down across the Lower Trans Pecos on Friday. (This afternoon through Friday night) Scattered showers are ongoing over portions of southeast New Mexico, along the leading edge of an upper-level trough. The upper low is currently headed toward the Four Corners region. Friday, the upper low continues a slow track from the Rockies into the southern Great Plains. Disturbances rounding the base of the trough come out of northern Mexico while a Pacific front approaches out of New Mexico. The best (40-70%) rain chances shall overlay the Permian Basin and the Lower Trans-Pecos.
- Widespread freezing temperatures tonight, mainly south of Highway 30. Additional headlines are possible for Friday night with temperatures dropping into the lower 30s across the entire forecast area. Given the trough across the northeastern US, streams of vorticity run northwest to southeast across Lake MI and that paired with CAA allows for lake effect clouds and convective rain showers. The trough slowly jogs eastward and this will push the trough east of the area Friday morning.

KEY MESSAGES: - Rain showers continue mainly north of I-80 - Temperatures trend near or a few degrees below seasonal - Areas of frost expected during pre-dawn hours Friday in parts of eastern Ohio --------------------------------------------------------------- Little change in the synoptic flow pattern through the near term as a large upper low continues to spin over eastern Canada, maintaining deep-layer northwest flow over the local area. The exception will be portions of eastern Ohio mainly west of I-77 and south of I-70, where skies may clear and winds relax enough to help lows drop to near freezing.
Brief upper ridging will build in before a tightly wrapped upper low drops into southern Manitoba tonight. Surface ridging currently over western MN will move off into MN/WI, allowing winds to steady out of the southeast and start to pick up later tonight. The upper low over Manitoba will dig down into the Red River Valley tomorrow, however, very little precipitation is expected with the system. Upper ridging to southwesterly flow aloft sets up over the weekend.
- Cooler and drying conditions are expected today with readings at or just below normal. The cut-off low continues to make its way across the region with the low center now entering far northwest Arizona. Despite the position of the low across our region, drier air has already swept through nearly all of our area with PWATs lowering to around 0. The presence of low across northern portions of the region for much of today will keep temperatures lower with highs only in the lower 80s across the south-central Arizona lower deserts to mostly in the mid 80s across the western deserts. Starting Friday, upper level ridging will gradually spread over the region from the west.
Early afternoon GOES-16 water vapor imagery shows a large-scale trough across the northeastern US and eastern Canada with the trough axis still west of our longitude. Broad southwest flow continues ahead of a secondary cold front / trough over the eastern Great Lakes. this shower activity will wane this evening with winds shifting to the west overnight with west northwest flow bringing cooler air into the region through Friday.
