KEY MESSAGES
- AN UPPER LEVEL RIDGE WILL BUILD IN THROUGH THE BEGINNING OF THE
WEEK HELPING TO REDUCE SHOWER ACTIVITY TO THE MORE TYPICAL
ISOLATED TO WIDELY SCATTERED COVERAGE DURING THE AFTERNOON.
- CONDITIONS WILL BECOME HOTTER AND MORE HUMID LATER IN THE WEEK
WITH AFTERNOON HEAT INDEX VALUES REACHING BETWEEN 100 AND 109
DEGREES.
DISCUSSION
(THIS EVENING THROUGH NEXT SUNDAY)
ISSUED AT 1258 PM CDT MON JUN 8 2026
CURRENTLY TEMPERATURES ARE IN THE 80S WITH DEWPOINTS IN THE 70S,
YIELDING HEAT INDICES IN THE 90S ACROSS MUCH OF THE CWA. THERE ARE
SOME ISOLATED SHOWERS ONGOING THIS AFTERNOON, WITH ACTIVITY
GENERALLY EXPECTED TO TAPER AFTER SUNSET. WHILE PWATS ARE STILL
ELEVATED, THEY REMAIN CLOSER TO THE 90TH PERCENTILE INSTEAD OF
FLIRTING WITH THE DAILY MAXIMUM, SO THE COLUMN IS A BIT DRIER
TODAY THAN DAYS PREVIOUS. FORECAST PWAT VALUES THROUGH THE WORK
WEEK ARE EXPECTED TO RANGE FROM AROUND THE 75TH PERCENTILE TO NEAR
OR ABOVE THE 90TH PERCENTILE, WITH POPS GENERALLY REMAINING IN THE
20 TO 50 PERCENT RANGE.
AT THE SURFACE, AN AREA OF HIGH PRESSURE OVER THE EAST COAST /
ATLANTIC WILL ALLOW SOUTHERLY TO SOUTHEASTERLY FLOW TO PREVAIL
THROUGH NEARLY THE ENTIRE FORECAST PERIOD. ALOFT, AN UPPER RIDGE
OVER THE EASTERN GULF WILL EXPAND WESTWARD ACROSS THE REMAINDER OF
THE GULF. A MORE TYPICAL SUMMERTIME PATTERN IS THEN EXPECTED TO
DEVELOP, CHARACTERIZED BY SLIGHTLY ABOVE NORMAL TEMPERATURES AND
MAINLY DIURNALLY DRIVEN SHOWERS AND THUNDERSTORMS. TEMPERATURES
WILL CLIMB INTO THE LOWER TO MIDDLE 90S WHILE DEWPOINTS REMAIN IN
THE 70S, SO SOME LOCATIONS COULD SEE HEAT INDICES CREEP INTO HEAT
ADVISORY CRITERIA.
AVIATION
(00Z TAFS)
ISSUED AT 715 PM CDT MON JUN 8 2026

A LIGHT TO MODERATE ONSHORE FLOW ALONG WITH SEAS NEAR 1 TO 4 FEET
WILL PREVAIL THROUGH THE WORK WEEK, WITH LITTLE DAY TO DAY CHANGES
EXPECTED. AN ISOLATED SHOWER/STORM OR TWO IS POSSIBLE EACH DAY,
BUT OVERALL DRY CONDITIONS ARE EXPECTED TO PREVAIL.
FIRE WEATHER
ISSUED AT 1258 PM CDT MON JUN 8 2026
MINRH VALUES WILL RUN IN THE 50-70% RANGE EACH DAY THROUGH THE
WORK WEEK AS A WARM AND MOIST SUMMERTIME ATMOSPHERE REMAINS IN
PLACE. WHILE ISOLATED AFTERNOON SHOWERS AND STORMS WILL BE
POSSIBLE EACH DAY, A BIT OF CAPPING ALOFT WILL KEEP RAIN CHANCES
LARGELY IN CHECK THROUGH THE WEEK.
