DISCUSSION
ISSUED AT 1217 PM CDT WED SEP 2 2026
STRONG UPPER LEVEL RIDGING WILL CONTINUE THROUGHOUT THE SOUTH-
SOUTHEAST CONUS THROUGH EARLY NEXT WEEK, WHICH WILL KEEP CONDITIONS
UNSEASONABLY HOT AND MOSTLY RAIN-FREE THROUGHOUT DEEP SOUTH TEXAS.
POTENTIAL RECORD HIGH TEMPERATURES ARE POSSIBLE TODAY THROUGH THE
WEEKEND AS HIGH TEMPERATURES REACH THE TRIPLE DIGITS EACH AFTERNOON,
WITH MAJOR (LEVEL 3 OF 4) TO EXTREME (LEVEL 4 OF 4) HEAT RISK
EXPECTED TO PERSIST. THE HOTTEST TEMPERATURES ARE EXPECTED TO
OCCUR THIS AFTERNOON, AND A HEAT ADVISORY HAS BEEN ISSUED FOR
INLAND CAMERON, WILLACY, AND KENEDY COUNTIES UNTIL 6 PM. HEAT
ADVISORIES AND/OR SPECIAL WEATHER STATEMENTS ARE ALSO POSSIBLE
TOMORROW AND FRIDAY AS WELL.
A SLIGHT INCREASE IN GULF MOISTURE THIS WEEKEND WILL CREATE A LOW
(10 TO 20%) CHANCE OF SEA BREEZE CONVECTION STARTING SATURDAY AND
CONTINUING THROUGH THE MIDDLE OF NEXT WEEK. SHOWERS AND
THUNDERSTORMS, MAINLY EAST OF I-69C, WILL BE POSSIBLE.
THE HOT WEATHER, COMBINED WITH DRY FUELS AND LOWER RELATIVE
HUMIDITIES (PARTICULARLY IN THE WESTERN COUNTIES) WILL SUPPORT
ENHANCED WILDFIRE DANGER THROUGH THE WEEKEND. WHILE FIRE DANGER
STATEMENTS ARE NOT ANTICIPATED DUE TO LOWER WIND SPEEDS, FIRES
COULD CATCH VERY EASILY DUE TO HOT AND DRY CONDITIONS. OUTDOOR
BURNING IS HIGHLY DISCOURAGED.
