LONG TERM
Issued 1142 PM CST Fri Nov 6 2026

Monday through Thursday:

Brief WAA behind the Sunday cold front will keep temperatures above normal in the upper 50s to near 60s on Monday. Then, series of dry troughs this week and relative high pressure will keep precipitation at bay much of this week amid a mix of sun and clouds. The latter part of the extended period has trended colder as a stronger cold front and Canadian high are expected to move out of central Canada into the upper Great Lakes region late this week. This will lead to temperatures at or slightly below normal for Thursday and Friday. Some lake effect rain showers may occur along the lakeshore on Thursday (15 to 30% chances) as favorable fetch and delta-T's will induce lake driven convection.

Winds will continue to gradually ease overnight into Saturday as high pressure moves overhead overnight and then moves south into the Ohio River Valley through Saturday.

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. Locally, this may lead to Small Craft Advisory conditions Sunday afternoon. Breezy winds will then persist at times early next week as another shortwave moves through by Monday night.
