DAILY HIGHS IN THE MIDDLE 90S TO LOW 100S, AND MAXIMUM HEAT
INDEX VALUES AROUND 100 TO 105. CONFIDENCE IS HIGH IN THE

EXTREME (4 OF 4) HEAT RISK AND WBGT RISK EXPECTED ACROSS THE
AREA.

SHORT TERM /THROUGH TONIGHT/
ISSUED AT 1216 PM CDT SAT AUG 29 2026
CONTINUED WARMER BUT OTHERWISE QUIET WEATHER THROUGH TONIGHT.
LOWS TONIGHT WILL RANGE FROM THE MID 60S OVER SOUTH-CENTRAL MO
TO THE MID 70S NORTHWEST OF I-44.
LONG TERM /SUNDAY THROUGH SATURDAY/
ISSUED AT 1216 PM CDT SAT AUG 29 2026
FAIRLY SIMILAR CONDITIONS ARE EXPECTED SUNDAY THROUGH AT LEAST
NEXT SATURDAY AS UPPER LEVEL RIDGING MEANDERS ACROSS THE
MIDWEST.
PRECIPITATION: LITTLE TO NONE. 15-20% CHANCES NEXT SATURDAY.
HEAT: IN GENERAL, AREAS NW OF I-44 SHOULD SEE THE HIGHER END OF
THE TEMPERATURE SPECTRUM, BUT AREAS SE OF I-44 WILL HAVE HIGHER
HUMIDITY, SO IMPACTS WILL OVERALL BE SIMILAR ACROSS THE AREA.
EXPECTED DAILY HIGHS IN THE MID 90S TO LOW 100S. LOOK FOR HEAT
INDEX VALUES OF 100-105+. HEAT RISK WILL BE IN THE MAJOR TO
EXTREME CATEGORIES. WBGT CATEGORIES WILL BE HIGH TO EXTREME.
HEAT HEADLINES WILL LIKELY BE NEEDED IN THE COMING DAYS. THIS IS
WELL SUPPORTED BY THE NBM, ENSEMBLES, AND ENSEMBLE TOOLS.
FOR ADDITIONAL CONTEXT, AVERAGE HIGHS IN LATE AUGUST TO EARLY
SEPTEMBER ARE IN THE MID 80S, SO WE WILL LIKELY SEE TEMPERATURES
OF 10-15+ DEGREES ABOVE NORMAL. SOME RECORDS (SEE CLIMATE
SECTION) MAY BE BROKEN, BUT THE CURRENT FORECAST KEEPS
TEMPERATURES BELOW RECORDS.
HOW LONG WILL THE HEAT LAST? ENSEMBLE GUIDANCE AS CPC OUTLOOKS
SUGGEST POSSIBLY INTO THE MIDDLE OF SEPTEMBER. THIS WILL
CONTINUE OUR RAPID ONSET DROUGHT CONDITIONS.
FIRE WEATHER CONCERNS SUNDAY: HOT AND DRY CONDITIONS (MINIMUM RH
OF 25-35%) AND S/SW WINDS OF 10-15 MPH GUSTING TO 15-25 MPH
(STRONGEST ALONG/WEST OF I-49) MAY LEAD TO ELEVATED GRASSFIRE
POTENTIAL.
AVIATION /00Z TAFS THROUGH 00Z SUNDAY/
ISSUED AT 600 PM CDT SAT AUG 29 2026
VFR CONDITIONS THROUGH THE PERIOD WITH A FEW PASSING HIGH CLOUDS
AND NO PRECIPITATION EXPECTED. LIGHT WINDS VARY BETWEEN EASTERLY
