- Chances (40-80 percent) for showers and storms return Wednesday evening and persist into Friday. Heavy rain is possible. Severe weather is not expected. High temperatures will be in the upper 70s and 80s.

Severe weather is not expected. High temperatures will be in the 80s.
DISCUSSION
Issued at 504 AM EDT Tue Aug 4 2026
An upper level ridge/sfc high pressure builds in today and lingers through Wed. Because of this, we have a nice break in active weather through Wednesday, with partly to mostly clear skies, light winds, and highs in the 80s. Patchy fog is possible early this morning, but should improve shortly after sunrise.
Next chance for showers and storms looks to be Wed evening, continuing through early next week. Our upper level ridge drifts eastward and a broad trough stemming from a closed low over Hudson Bay takes hold of the Great Lakes region. A cold front will move in from NW to SE, stalling along the southern border of our CWA by Saturday morning. We'll see return flow around high pressure over the Atlantic bring moisture from the gulf into the area during this time. Have around a 40-80 percent chance for showers and storms Wed PM into Friday, which is when chances begin to dwindle from NW to SE. Heavy rain is possible. Severe weather is not expected at this time. With the front stalling south of the CWA, we could end up dry Saturday outside of low 20 percent chances or so in the vicinity of the front. Some of the guidance generates precipitation in the afternoon with an incoming shortwave, but my confidence isn't too high in this. Highs will be in the upper 70s and 80s.
A couple additional waves move through the slightly troughed/zonal pattern aloft Sunday into Tuesday, bringing chances for additional showers/storms (20-40 percent). The best chances are associated with the stronger wave on Monday into Tuesday. Highs will be in the 80s.
