..NEW AVIATION
KEY MESSAGES
UPDATED AT 606 AM CDT THU SEP 3 2026
- MAJOR TO EXTREME HEAT RISK THROUGH THIS WEEK WITH HEAT INDEX
VALUES IN THE TRIPLE DIGITS. A HEAT ADVISORY REMAINS IN EFFECT
FOR ALL COUNTIES THROUGH FRIDAY.
- LOW CHANCE FOR AFTERNOON RAIN AND THUNDERSTORMS THROUGH NEXT
WEEK.
SHORT TERM
(TONIGHT THROUGH FRIDAY NIGHT)
ISSUED AT 1021 PM CDT WED SEP 2 2026
STRONG HIGH PRESSURE REMAINS CENTERED OVER THE AREA AND WILL
CONTINUE TO BE THE CAUSE OF VERY HOT TEMPERATURES THROUGH THE END OF
THE WEEK. HIGH TEMPERATURES ON THURSDAY ARE EXPECTED TO BE SIMILAR
TO WEDNESDAY WITH READINGS IN THE UPPER-90S AND HEAT INDICES IN THE
TRIPLE DIGITS. ONLY NOTEWORTHY CHANGE IN THE FORECAST IS THE LOW
CHANCE (10-15%) FOR POP-UP SHOWERS AND THUNDERSTORMS THURSDAY
AFTERNOON. THE PWAT ON THE EVENING SOUNDING CAME IN AT AN
IMPRESSIVE 1.90 INCHES, ABOVE THE 90TH PERCENTILE. THAT MOISTURE
AND PLENTY OF INSTABILITY MAY BE ENOUGH TO HELP OVERCOME THE
STRONG HIGH PRESSURE, AND CAMS ARE PICKING UP ON THIS AS WELL. NO
CONCERNS WITH THESE POTENTIAL POP-UPS. JUST CONSIDER YOURSELF
LUCKY IF YOU GET A LITTLE RELIEF FROM THE HEAT. SIMILAR CONDITIONS
EXPECTED ON FRIDAY WITH HIGHS STILL STUCK IN THE UPPER-90S WITH
ANOTHER LOW CHANCE FOR POP-UP STORMS. A HEAT ADVISORY REMAINS IN
EFFECT FOR ALL COUNTIES THROUGH FRIDAY.
LONG TERM
(SATURDAY THROUGH NEXT THURSDAY)
ISSUED AT 1021 PM CDT WED SEP 2 2026
BY THIS WEEKEND, THE HIGH PRESSURE SHIFTS OFF TO THE WEST, AND
TEMPERATURES WILL DIP EVER SO SLIGHTLY. BUT TEMPERATURES REMAINING
IN THE 90S THIS WEEKEND AND INTO AT LEAST THE FIRST HALF OF NEXT
WEEK WILL STILL BE WELL ABOVE NORMAL FOR EARLY SEPTEMBER. AS FAR AS
RAIN GOES, NORTHWEST FLOW WILL OPEN THE DOOR FOR LOW RAIN CHANCES,
LIKELY DIURNALLY-DRIVEN, TO CONTINUE INTO THIS WEEKEND AND EARLY
NEXT WEEK. UNFORTUNATELY, THESE HOTTER TEMPERATURES LOOK TO
CONTINUE WELL INTO NEXT WEEK AS ENSEMBLE GUIDANCE IS FAVORING THE
HIGH PRESSURE TO BUILD BACK TOWARDS OUR AREA, KEEPING THESE ABOVE
NORMAL TEMPERATURES CONTINUING IN THE EXTENDED FORECAST.
