DISCUSSION

Issued at 203 AM CDT Thu Aug 13 2026

A few remnant showers and possibly a thunderstorm will pass through northern portions of the area this morning; however, there should be a diminishing trend through sunrise.

The ridge that has been in place across the area the past few days will gradually build back across the area today; however, another MCS is expected to slide around the periphery of the ridge this afternoon. The latest trends would have this staying just north of the CWA, across northern IL this afternoon before diving southeast through central IN to southwest OH this evening. It may brush close enough to touch off storms over southwest IN, but the chances look pretty slim overall. Kept a 20-30% chance up near the Evansville Tri- State area, with mainly dry conditions elsewhere as the ridge builds back into the area from the southwest. In fact, the SPC has kept the southwest IN and adjacent portions of KY/IL in a Marginal Risk of severe weather today with the main threat being damaging winds if storms happen to pass through that area.

The ridge will continue to expand and intensify across the area for the end of the week into the weekend, which will allow temperatures to climb along with the humidity. The Extreme Heat Warning as kept in place and unchanged from the previous forecast update with heat index values expected to be in the 105-115 degree range through the weekend! This will be a dangerous and prolonged period of extreme heat.

A frontal boundary is progged to sag southward into the area for Monday, which may briefly bring slightly cooler temperatures (upper 80s to low 90s) for Tuesday into Wednesday of next week. At this point, any break in the heat would be great!!

Issued at 1132 PM CDT Wed Aug 12 2026

High clouds remain over the area after storms moved through earlier this evening. Some additional showers and storms near St. Louis may work their way towards MVN near morning and into the morning hours. Put in a PROB30 at MVN but confidence is on the lower side currently. High clouds should remain for most of the day and start clearing out in the late evening/overnight. Winds will be out of the southwest at around 5-8 kts and will come down overnight.
