KEY MESSAGES
- Warmer temperatures today will give way to a cooling trend this weekend as a cold front brings falling temperatures along with increasing chances for showers.
- Breezy Saturday into Sunday, especially along the Keweenaw and near Lake Superior. There is a high risk for gales over the central and eastern parts of the lake Saturday afternoon through Sunday evening.
- Lake effect snow showers return to northwest wind snowbelts late this weekend and continue through early next week, mainly in the eastern U.P. Only minor accumulations are expected with minimal impacts through the period.

IR satellite imagery reveals mostly clear skies across Upper Michigan this morning, save for a patch of broken mid level cloud cover drifting over the central UP. Expect another quiet day today, characterized by mostly sunny skies as an upper level ridge of high pressure traverses the Great Lakes. This coupled with low level southerly flow will help to push temperatures into the 50s across much of the area this afternoon, with highs potentially getting into the mid to upper 50s in the west.
More active weather returns on Saturday as a cold front moves into the area in the morning, bringing the next chance for precipitation.
The best rain chances will be across the east, with model QPF amounts mostly capped around a tenth of an inch owing to plenty of dry air to overcome in the low levels of the atmosphere.
Temperatures will be a bit cooler than Friday, but will still make it into the upper 40s in most spots and push 50 across the east and closer to Lake Michigan. Saturday will also be quite breezy as winds shift northwesterly behind the front and cold advection helps to mix stronger gusts down to the surface. Gusts exceeding 30 mph will be common along the Lake Superior shoreline, with the NBM indicating around a 40% chance for gusts as high as 40 mph along the Keweenaw.
The colder air mass continues to filter into the region through Sunday as 850 mb temps fall to around -10 C by Sunday morning and highs highs top out in the 30s in most locations for Sunday afternoon. As such, will see precipitation start to transition back over to snow Saturday night into Sunday, favoring the typical northwest wind snow belts mainly from Marquette/Alger County. Do not expect any major accumulations or impacts from this snow as a continued lack of moisture and relatively low inversion heights limit snowfall potential. Winds will also remain breezy through Sun day as Gales persist over the central and eastern parts of Lake Superior through Sunday evening.
Cold northwest flow looks to maintain a low-impact lake effect rain/snow shower regime across the eastern U.P. into the first half of next week, with temperatures gradually moderating from the 30s closer to seasonal norms in the low to mid 40s by the middle of the week.

VFR conditions will prevail today with high clouds moving over the region with mostly light winds. Tonight, southerly flow prevails ahead of a Saturday morning cold front. Expecting a few hours of low level wind shear tonight at all sites with periodic gusts near 20kts at KIWD. Additionally, guidance is suggesting quickly developing flight categories at KSAW after midnight.

Issued at 404 AM EST Fri Nov 14 2025
Quiet this morning with southwest winds mostly in the 10-15 kt range across Lake Superior. Winds will increase today as southerly flow increase ahead of an approaching frontal system, with 25-30 kt gusts expected over the eastern half of the lake this afternoon and evening as waves build into the 3 -5 ft range.
Winds quickly shift westerly and then northwesterly on Saturday behind a cold front, with strong cold advection helping to mix 35-40 kt gusts down to the surface. Have therefore hoisted a Gale Watch for the central and eastern portions of the lake from Saturday afternoon through Sunday evening, with waves building to 8-13 ft from the Keweenaw eastward by Saturday night. Northwest winds gradually diminish from Sunday night through the early part of next week, dropping below 20 kt by Tuesday with waves subsiding accordingly.
