DISCUSSION

Issued at 226 AM CDT Wed Aug 5 2026

Broad longwave troughing aloft is set up over much of the north central CONUS and the trof axis will slowly shift eastward today to be positioned through the Mississippi Valley region. At the sfc a cold front will be situated northeast to southwest through north central IL, central MO, and southeast KS this afternoon and evening which is where it will largely stall out. After one more day of dry and mild conditions today, a ripple in the flow aloft and the proximity of the front will spur on a few showers an storms by Thursday morning across parts of SEMO and western portions of southern IL. After a mainly dry afternoon Thursday, 30-60% PoPs come back overnight and through Friday then taper off Saturday morning over west KY. Not everyone will see rain during this time frame though. Thursday in particular, a few strong to severe storms can't be ruled out.

High pressure over the Four Corners region will expand eastward on Sunday bringing back highs in the lower 90s and dewpoints in the mid to upper 70s. This will push heat indices back into the 100-105 degree range through early week. Dry conditions are expected until Tuesday evening through Wednesday when 20-30% PoPs return to the forecast and bring some potential relief from the heat.
