DISCUSSION
ISSUED AT 1057 PM CDT WED AUG 19 2026
THURSDAY INTO FRIDAY WILL LIKELY FEATURE MUCH OF THE SAME AS WE
HAVE HAD THESE PAST FEW DAYS. SCATTERED TO LOCALLY NUMEROUS
AFTERNOON SHOWERS AND THUNDERSTORMS CAN ONCE AGAIN BE EXPECTED
AFTER REACHING OPPRESSIVE AFTERNOON HIGHS AND HEAT INDICES ACROSS
THE AREA. HEAT ADVISORIES CONTINUE FOR THE WHOLE AREA WITH
EXPECTED HEAT INDICES RISING TO NEAR 112 THURSDAY. WE'LL LIKELY
SEE SIMILAR VALUES FOR FRIDAY AND ADDITIONAL HEAT ADVISORIES WILL
LIKELY BE NEEDED. AFTERNOON STORMS WILL CONTINUE TO BE BREEZY WITH
LOCALIZED DAMAGING WIND GUSTS ASSOCIATED WITH WET MICROBURSTS
CONTINUING TO BE POSSIBLE THROUGH FRIDAY.
AS WE GET INTO THE WEEKEND, WE FINALLY SEE A BUDGE IN THE PATTERN
AS UPPER TROUGHING MOVES ACROSS THE AREA AND A WEAK FRONT TRIES TO
PUSH IN FROM THE NORTHWEST. AT A MINIMUM, THIS WILL HELP TO REDUCE
AFTERNOON DEWPOINTS SATURDAY INTO SUNDAY AND MAY FINALLY GIVE US A
REPRIEVE FROM THE HEAT ADVISORY CRITERIA HEAT INDICES. DESPITE
THIS, IT WILL REMAIN HOT AS HIGHS STAY IN THE MIDDLE TO UPPER 90'S
AND HEAT INDICES REMAIN IN THE 100 TO 108 RANGE. SATURDAY AND
SUNDAY WILL FEATURE AT BEST ISOLATED COVERAGE FOR STORMS GIVEN THE
DRIER AIR IN PLACE, BUT ANY STORM THAT CAN MANAGE TO FORM MAY
PRODUCE GUSTY WINDS.
AS WE HEAD INTO NEXT WEEK UPPER RIDGING STARTS TO WORK ITS WAY
BACK INTO THE AREA AND THE ATMOSPHERIC PROFILE BEGINS MOISTENING
UP AGAIN, ALLOWING FOR MORE TYPICAL AFTERNOON SHOWERS AND
THUNDERSTORMS WITH GUSTY WINDS AND LOCALIZED DAMAGING WIND GUSTS.
AFTERNOON HIGHS WILL GENERALLY STAY IN THE MIDDLE 90'S WITH HEAT
INDICES REMAINING IN THAT 100 TO 108 RANGE. THE RIP CURRENT RISK
WILL REMAIN MODERATE FOR FLORIDA PANHANDLE BEACHES THURSDAY INTO
THURSDAY NIGHT, DIMINISHING TO A LOW RISK FRIDAY THROUGH THE
WEEKEND FOR ALL BEACHES. MM/25
