KEY MESSAGES

- Strong to severe thunderstorms and locally heavy rainfall are possible today into this evening as a storm complex moves through the region. - Dangerous heat stress will return for much of the area today and continue through the work week.

DISCUSSION

Issued at 1244 PM CDT Mon Jun 22 2026

Showers and thunderstorms are ongoing this afternoon as the remnants of an MCS is moving across the area. Expect these storms to continue to progress east across the area through the afternoon hours. We already have a slight risk for the northeastern portions of the area, with a marginal risk over the remainder. A severe watch has been issued by SPC for mainly the central and eastern portions of the area through the afternoon hours. Hi-res models suggest that the frontal boundary will drop south over the area overnight, with showers/storms continuing.

The axis of deeper moisture will be left stretched out from northwest to southeast across our forecast area Tuesday into Wednesday, and additional thunderstorm complexes will be possible in this pattern. Expect heat, marginally severe, and at least isolated flash flooding threats to be possible into Thursday. The core of an upper-level ridge will translate eastward and become established over our region Friday into the weekend, and at this time it appears that Friday may be the first day in while without any mentionable rain chances. Dangerous heat threats will increase over the weekend. /15/NF/
