KEY MESSAGES
- THERE IS A MARGINAL RISK FOR A SEVERE STORMS TODAY AHEAD OF AN

DISCUSSION
ISSUED AT 246 PM CDT MON SEP 21 2026
FOR THIS AFTERNOON, WE ARE MONITORING THE DEVELOPMENT OF A FEW
STRONG/SEVERE STORMS AHEAD OF THE COLD FRONT, AND THERE CONTINUES
TO BE A MARGINAL SEVERE RISK FOR DAMAGING WIND GUSTS DURING PEAK
HEATING OVER MUCH OF THE AREA. LOOKING AHEAD, IT DOES APPEAR WE
ARE NEARING THE END OF THE "DANGEROUS" HEAT REGIME IN THIS LONG
AND BRUTALLY HOT SUMMER OF 2026. TOMORROW WILL SEE THE MUCH
ANTICIPATED COLD FRONT PUSH THROUGH THE AREA, AND WHILE THE AIR
FOLLOWING THE FRONT WILL NOT BE COOL AND DRY ENOUGH TO REMIND US
OF FALL, IT WILL AT LEAST BRING CONDITIONS THAT ARE MORE TYPICAL
OF LATE SEPTEMBER.
FOR TUESDAY, WE COULD SEE PORTIONS OF EASTERN MS GET INTO THE
PICTURE FOR A MARGINAL RISK FOR SEVERE STORMS, BUT IT APPEARS MOST
OF THE ACTIVITY WILL STAY EAST OF US AND WILL HOLD OFF ON ANY
MESSAGING FOR NOW. LOOKING AHEAD FOR LATE THIS WEEK INTO NEXT
WEEKEND, AS MENTIONED, DRIER CONDITIONS CAN BE EXPECTED WITH "LESS
HOT" TEMPERATURES. OVERALL, WEATHER IMPACTS WILL MOSTLY BE TIED
TO EARLY WEEK HEAT AND CONVECTIVE POTENTIAL. /EC/
