.DISCUSSION...
Issued at 201 AM CDT Wed Oct 8 2025

High pressure is setting up over the Midwest, delivering clear
skies, cooler temperatures, and dry weather. Currently, some
localized, patchy fog has developed overnight. It should dissipate
just before sunrise. Otherwise, today will be a pleasant autumn
day, with highs in the upper 60s to low 70s. Dry weather is
expected to linger into the new week.

Overnight temperatures tonight and tomorrow night may dip down into
frost development territory for some cooler locations. Temperatures
Thursday morning will be in the upper 30s north of I-74. NBM
probabilities for dipping below 38 degrees is roughly 30-60% from a
Bloomington to Paris line north Thursday morning. Friday morning
will be similar, but with a 50-70% chance of dipping below 38
degrees east of I-57. These temperatures both morning and a good
radiational cooling set up, frost formation is possible in the
coldest locations.

Ridging hold in place through the weekend. We shift to more
southerly winds by daytime Friday. Daytime temperatures will
increase back into the upper 70s for the weekend, then into the 80s
for the new week. Lows will also increase back into the 50s to low
60s by the weekend.
