DISCUSSION
ISSUED AT 1213 PM CDT MON AUG 10 2026
UPPER-LEVEL RIDGING REMAINS DOMINANT OVER THE CENTRAL-SOUTHERN US,
WITH SURFACE LEVEL HIGH PRESSURE OVER THE GULF. THIS PATTERN IS
EXPECTED TO CONTINUE THROUGHOUT THE NEXT WEEK, WHICH WILL CONTINUE
TO SUPPORT HOT, HUMID, AND GENERALLY RAIN-FREE CONDITIONS FOR DEEP
SOUTH TEXAS.
HEAT RISK WILL BE OF THE MOST CONCERN THROUGHOUT THE WEEK, AS
TEMPERATURES SLOWLY WARM THROUGHOUT THE WEEK DUE TO STRENGTHENING
HIGH PRESSURE. UNSEASONABLY HOT TEMPERATURES ARE EXPECTED TO
CONTINUE. MODERATE (LEVEL 2 OF 4) TO MAJOR (LEVEL 3 OF 4) HEAT RISK
COULD INCREASE TO MAJOR TO EXTREME (LEVEL 4 OF 4) HEAT RISK BY THE
END OF THE WEEK, WITH HEAT ADVISORIES POSSIBLE.
CONDITIONS ARE EXPECTED TO BECOME INCREASINGLY WINDY THROUGHOUT THE
WEEK AS THE PRESSURE GRADIENT TIGHTENS. THIS COULD SUPPORT AN
INCREASED RISK OF RIP CURRENTS AT AREA BEACHES LATER IN THE WEEK.
