NEAR TERM
(TODAY)
ISSUED AT 416 AM CDT MON AUG 31 2026
PROLONGED UPPER LEVEL RIDGING WILL MAKE FOR A DRY BUT HOT FORECAST
THROUGH MUCH OF THE WEEK. EARLY MORNING TEMPERATURES HAVE FALLEN
TO THE LOWER 70S WITH CLEAR SKIES AND LIGHT WINDS ALLOWING FOR
GOOD RADIATIONAL COOLING. DANGEROUS HEAT WILL BE THE MAIN THREAT
TODAY WITH AFTERNOON HEAT INDICES APPROACHING 105 DEGREES IN SOME
LOCATIONS. ALTHOUGH SOME LOCATIONS MAY MEET HEAT ADVISORY CRITERIA
OF 105 DEGREE HEAT INDEX, LIMITED MOISTURE/HUMIDITY DURING THIS
STRETCH OF HOT TEMPERATURES WILL KEEP HEAT INDICES LARGELY BELOW
105 DEGREES AND SHOULD KEEP DIURNAL THUNDERSTORMS OUT OF THE
FORECAST AS WELL. WITH THAT BEING SAID, THIS HEAT WILL STILL POSE
A THREAT TO LIFE ESPECIALLY FOR THOSE PARTICULARLY VULNERABLE TO
THE HEAT OR THOSE WITHOUT ADEQUATE COOLING AND HYDRATION. REMEMBER
TO STAY HYDRATED, TAKE FREQUENT BREAKS, AND NEVER LEAVE PEOPLE OR
PETS UNATTENDED IN VEHICLES!
SHORT TERM
(MONDAY NIGHT THROUGH WEDNESDAY NIGHT)
ISSUED AT 755 PM CDT SUN AUG 30 2026
THE MID/UPPER LEVEL RIDGE AMPLIFIES AND SHIFTS FURTHER EAST HEADING
INTO THE MIDDLE OF THE WEEK. SUBSIDENCE UNDER THE RIDGE WILL KEEP
CLOUD COVER LIMITED WITH DRY WEATHER CONTINUING THROUGH THE END OF
THE SHORT TERM PERIOD. EXPECT HIGHS ON TUESDAY AND WEDNESDAY TO
RISE INTO THE MID TO UPPER 90S WITH HEAT INDEX VALUES BETWEEN
100-105 DEGREES. WITH THE RECENT DRY CONDITIONS, DEWPOINTS SHOULD
MIX OUT A BIT EACH AFTERNOON WHICH SHOULD KEEP US BELOW ADVISORY
CRITERIA. REGARDLESS, EVEN IF WE DON'T EXCEED ADVISORY CRITERIA
THE HEAT WILL BE DANGEROUS AS WBGT RISES BETWEEN 87-90 DEGREES AND
MODERATE TO MAJOR HEAT RISK IS FORECAST. NOT MUCH RELIEF IS
EXPECTED OVERNIGHT AS LOWS ONLY DROP DOWN INTO THE LOWER 70S.
LONG TERM
(THURSDAY THROUGH SUNDAY)
ISSUED AT 755 PM CDT SUN AUG 30 2026
THE LONG TERM FORECAST WILL OFFER MORE OF THE SAME. AT THE SURFACE,
HIGH PRESSURE WILL DOMINATE, KEEPING TEMPS IN THE MID TO HIGH 90S
THROUGH THE WEEKEND. WITH RIDGING REMAINING IN PLACE IN THE MID
LEVELS TOO, OUR SAVING GRACE WILL BE THE FACT THAT OUR DEW POINTS
LOOK TO REMAIN IN THE HIGH 60S TO LOW 70S. THIS WILL LIMIT HOW HIGH
OUR HEAT INDICES CAN REACH WITH UNCERTAINTY REMAINING ON IF WE WILL
MEET HEAT ADVISORY CRITERIA. INVERSELY, SINCE WE WILL BE SLIGHTLY
DRIER, THERE IS SOME CONCERN FOR OVER PREFORMING ON CURRENT HIGH
TEMPERATURE FORECASTS. SOME DETERMINISTIC MODELS FLIRT WITH TRIPLE
DIGIT HIGHS THIS WEEKEND. WHILE WE HAVE LOW CONFIDENCE IN THIS
OCCURRING, IT WILL BE A TREND WE KEEP AN EYE ON. FROM SUNDAY FORWARD
THE FORECAST BECOMES SOMEWHAT MURKY. MODELS HAVE PICKED UP ON A
PASSING COLD FRONT YET ARE IN DISAGREEMENT ON WHEN AND IF IT COMES
THROUGH. IF THE COLD FRONT DOES MAKE IT THROUGH ON SUNDAY AS THE NBM
SUGGEST, HIGHS WILL DROP BACK TO THE LOW 90S. IF THE FRONT STALLS OR
DAMPENS BEFORE IT GETS HERE, HIGHS WILL LIKELY REMAIN IN THE HIGH 90S
THROUGH THE START OF THE NEXT WORK WEEK. MAKE SURE TO CONTINUE TO
PRACTICE PROPER HEAT SAFETY AND CHECK BACK FOR UPDATES.
