.DISCUSSION...
Issued at 153 AM EDT Wed May 7 2025

Radiational fog was developing over northeast Indiana into
northwest Ohio early this morning where some visibilities were
less than 1 mile. Any patchy dense fog will be brief and should
mix out by mid morning.

An upper low was lifting out of the region but was still
expected to allow light showers near and north of the Michigan
border. The showers should end by midnight tonight. Cooler
weather can be expected Thursday with highs in the 60s.

Much warmer air will reach the area early next week as an upper
level ridge builds east into the Upper Midwest and Midwest.
Given 850 mb temperatures between +10C and +13C per GFS and
ECMWF, highs should reach between 75 and 80 Monday and Tuesday.
Showers and a few storms are likely early next week as some
energy from a nearly stationary upper low near the Ohio River
reaches the area.
