DISCUSSION
ISSUED AT 1005 PM CDT SUN SEP 6 2026
HOT TEMPERATURES WILL CONTINUE TO BE THE MAIN FOCUS THROUGH THE
FORECAST PERIOD. FOR THE REMAINDER OF THE LABOR DAY WEEKEND AND INTO
NEXT WEEK, MOST INLAND LOCATIONS WILL CONTINUE TO SEE AFTERNOON
HIGHS IN TRIPLE DIGITS WITH LOCATIONS RIGHT ALONG THE COAST
REMAINING IN THE 90S. HEAT INDICES OF 105-110 DEGREES ARE EXPECTED
ACROSS THE REGION EACH AFTERNOON WITH SOME LOCATIONS BRIEFLY
EXCEEDING 111 DEGREES. WHILE WE GENERALLY EXPECT TO REMAIN JUST
SHY OF HEAT ADVISORY CRITERIA EACH DAY, TUESDAY LOOKS TO BE THE
BEST LIKELIHOOD FOR ANY POTENTIAL HEAT ADVISORY.
RAIN CHANCES WILL CONTINUE INTO THE MIDDLE OF THE WEEK WITH A
10-25% CHANCE MOST DAYS, PRIMARILY ALONG THE SEA BREEZE. BEST
CHANCE OF RAIN WILL BE ON WEDNESDAY WHERE CHANCES INCREASE TO
30-40%. ANY CONVECTION THAT DOES DEVELOP COULD PRODUCE LOCALLY
HEAVY RAIN, GUSTY WINDS, AND CLOUD TO GROUND LIGHTING.
WHILE THERE IS A LOW RISK OF RIP CURRENTS AT AREA BEACHES, LIFE
THREATENING RIPS CURRENTS OFTEN OCCUR NEAR JETTIES AND PIERS. USE
CAUTION IF ENTERING THE WATER.
