KEY MESSAGES

- Limited Threat of dangerous heat stress continues today.

DISCUSSION

Issued at 300 PM CDT Tue Sep 22 2026

For this afternoon, we are monitoring the development of isolated strong to severe storms ahead of the cold front which is currently pushing into northern portions of the forecast area. Overall, the low/mid level lapse rates are not as favorable today for severe microbursts with damaging winds, so expect less coverage of intense convection as we go through the remainder of the day. The official beginning of fall on the calendar is today, and this just happens to coincide with what will hopefully be this year's last episode of "dangerous heat" in our area. While conditions will not remind one of fall, we can at least expect what would be considered more typical of September.

Looking ahead for late this week and through the weekend, drier and "less hot" conditions will continue. Then by the time we get to the middle of next week, there may be a more signicant frontal boundary that pushes slowly into our region with sufficient moisture and ascent for greater rain chances. /EC/
