DISCUSSION
ISSUED AT 124 AM CDT SAT SEP 12 2026
MAIN CONCERN THROUGH THE WEEKEND CONTINUES TO BE THE HEAT. HEAT
INDICES UP TO 114 ARE FORECAST ACROSS MANY LOCATIONS THIS AFTERNOON.
THUS, A HEAT ADVISORY HAS BEEN ISSUED FROM NOON TO 6 PM FOR MOST OF
S TX. A FEW PLACES MAY BRIEFLY EXCEED 115, BUT MOST PLACES WILL
REMAIN BELOW 115. MAJOR TO EXTREME RISK OF HEAT RELATED IMPACTS WILL
CONTINUE INTO EARLY NEXT WEEK AND HEAT ADVISORIES MAY BE NEEDED AT
TIMES.
LESS MOISTURE AND MID LEVEL RIDGING ACROSS NORTHEASTERN MEXICO AND
WEST TX WILL LEAD TO VERY LOW RAIN CHANCES TODAY. RAIN CHANCES
INCREASE SLIGHTLY SUNDAY IN RESPONSE TO THE RIDGE BEING NUDGED
NORTHWARD AS AN INVERTED TROUGH SHIFTS WEST ACROSS S TX. THIS WILL
ALLOW FOR A SLIGHTLY MORE ACTIVE SEA BREEZE. ISOLATED SEA BREEZE
CONVECTION IS EXPECTED EARLY NEXT WEEK WITH THE POTENTIAL FOR
INCREASED ACTIVITY BY MID TO LATE WEEK. MODELS HAVE BEEN VARYING ON
WHICH DAY HAS THE BEST CHANCE OF RAIN, BUT IT DOES LOOK LIKE
SOMETIME BETWEEN WEDNESDAY AND FRIDAY MAY SEE MEDIUM TO HIGH RAIN
CHANCES IN RESPONSE TO A SURGE OF DEEP MOISTURE FROM THE GULF WATERS
COMBINED WITH A MID LEVEL SHORT WAVE.
