The episode as NWS PAH wrote it up.
A cold front sagged through the Quad State from north to south later in the day on the 19th. A jagged line of thunderstorms developed during the afternoon across Southeast Missouri and Southern Illinois, dipping southward through mid afternoon. MLCAPE maxed out early afternoon around 3000-3500J/kg with DCAPE of 1200J/kg. Effective shear was limited, below 30kts. In Southern Illinois, the lone damage report was a tree blown down in Hardin County.

weekend, then slightly below normal temps to start off next

.DISCUSSION...
Issued at 209 PM CDT Tue Aug 19 2025
A Heat Advisory is still in effect this afternoon for continued heat
indices of 100-115. Upper level ridging is breaking down this
afternoon with the passage of a shortwave aloft. This will bring a
cold front through the area this afternoon and evening from north to
south. There is a Marginal Excessive Rainfall Outlook for this
afternoon with PWATs of 1.7 to 1.9. This means there could be heavy
downpours at times within these storms. SPC has us in a Marginal
Risk for severe weather today for downburst potential. Current
mesoanalysis supports 3,500 to 4,500 J/kg of SBCAPE across the area,
with little to no bulk shear, and low level lapse rates of around
8.5 degC/km along with the presence of inverted V soundings. This
all suggests the potential for strong winds via downbursts of
collapsing pulse storms.
Behind the front expect near normal temperatures through Sunday and
drier conditions. Highs will be in the mid 80s to lower 90s through
Sunday. Another cold front comes through late Saturday night into
Sunday and brings even cooler temperatures to start off the week.
Highs will be in the upper 70 to lower 80s with overnight lows in
the 50s!
