SHORT TERM
(TONIGHT THROUGH SATURDAY NIGHT)
ISSUED AT 1039 PM CDT THU AUG 13 2026
THE EVENING ACTIVITY HAS DISSIPATED LEAVING BEHIND MILD CONDITIONS
FOR THE REST OF THE NIGHT. FRIDAY WILL BE VERY SIMILAR TO TODAY WITH
THE UPPER RIDGE IN PLACE. TEMPERATURES WILL TOP OUT IN THE 90S WITH
DEW POINTS IN THE MID 70S. THIS WILL RESULT IN DANGEROUS HEAT WITH
AFTERNOON HEAT INDICES IN THE 100-110 DEGREE RANGE. THERE WILL STILL
BE SOME ISOLATED STORM ACTIVITY DURING THE AFTERNOON. WE SAW A
COUPLE OF STORMS PRODUCE SOME GUSTS AROUND 40 MPH TODAY AND THAT
WILL ONCE AGAIN BE POSSIBLE ON FRIDAY. SLOW STORM MOTION AND HEAVY
RAINFALL COULD LEAD TO SOME ISOLATED FLOODING ISSUES AS WELL.
FRIDAY NIGHT WILL BE THE SAME STORY WITH LOWS IN THE LOW TO MID 70S.
AIR TEMPERATURES WILL CREEP UP A DEGREE OR TWO ON SATURDAY BUT HEAT
INDICES LOOK TO REMAIN ABOUT THE SAME THANKS TO DEW POINTS BEING A
DEGREE OR TWO LOWER. STORM COVERAGE IS EXPECTED TO BE LOWER THAN
FRIDAY.
LONG TERM
(SUNDAY THROUGH NEXT FRIDAY)
ISSUED AT 1039 PM CDT THU AUG 13 2026
THE HEAT WILL CONTINUE ON SUNDAY AND MONDAY AS THE RIDGE HOLDS. THE
UPPER RIDGE WILL GET SQUEEZED SOUTHWARD ON MONDAY AS AN UPPER
TROUGH TRAVERSES THE SOUTHERN PART OF THE CANADIAN PROVINCES. A
WEAK SURFACE FRONT WILL PUSH INTO OUR AREA MONDAY AFTERNOON INTO
TUESDAY. THIS WILL DO TWO THINGS: 1) INCREASE RAIN AND STORM
CHANCES (20-30%) 2) TEMPORARILY KNOCK TEMPERATURES BACK CLOSER TO
NORMAL FOR TUESDAY. UNFORTUNATELY, THE RELIEF LOOKS LACKLUSTER AND
TEMPORARY. TEMPERATURES WILL AGAIN WARM FOR THE MIDDLE OF NEXT
WEEK.
