SHORT TERM
Issued 126 PM CST Fri Nov 6 2026

Tonight through Sunday:

Quiet weather is expected tonight through Saturday, as the northern axis of high pressure slides through southern Wisconsin. Scattered to broken lower clouds will persist in the east at times through tonight, with mainly high clouds then expected across the forecast area on Saturday under the high.
Temperatures should return back to around normal for afternoon highs tomorrow.

Dry weather will persist Sunday as low pressure passes by well to the northwest. Winds will gradually shift from southwest to northwest through the day as the low drags a weak surface front through southern Wisconsin. Temperatures a few degrees above normal are likely Sunday, especially given enough daytime heating prior to the frontal passage.

LONG TERM
Issued 126 PM CST Fri Nov 6 2026

Monday through Friday

Southerly winds will return quickly Monday ahead of another approaching low pressure trough. This should result in even milder conditions, with high temps likely cracking at least 60 most places. Dry weather should persist, with the surface low passing well to the north again.

A stronger upper level trough is expected to drop through the region later next week. Current deterministic model runs suggest this could be the coldest airmass of the season thus far. GFS and ECMWF ensemble temp means also show this potential for a shot of colder air. Shower chances would likely return Thursday into Friday if this stronger trough does drop through the area.

AVIATION
Issued 505 PM CST Fri Nov 6 2026

Quiet VFR conditions tonight as high pressure moving in will bring light winds and clear skies through most of the TAF period. Saturday night expect some lower CIGS to push in with uncertainty on the cloud coverage. Most models suggest SCT clouds but with heights in the IFR/MVFR range. If CIGS become more widespread we could easily see a period of impactful IFR/MVFR CIGS Saturday night into Sunday.

Issued 126 PM CST Fri Nov 6 2026

Northerly gale force winds will continue across the open waters until early this evening, as low pressure of 29.8 inches over Lake Huron heads southeast ahead high pressure. Winds will gradually ease overnight into Saturday as the northern axis of the high to the south moves overhead. Westerly winds will then increase Saturday night into Sunday between the high departing to the southeast and a trough of low pressure approaching from the northwest. Breezy winds will then persist at times early next week as another shortwave moves through by Monday night.
