KEY MESSAGES
ISSUED AT 200 AM CDT FRI AUG 7 2026
- MODERATE TO MAJOR RISK OF HEAT-RELATED IMPACTS THROUGH THE WEEK,
WITH PEAK HEAT INDICES 105 TO 110, AND HIGH TO EXTREME WBGT
VALUES.
- LOW-END CHANCES (20-40%) OF RAIN THIS WEEKEND WITH HIGHEST
TOTALS ALONG THE COAST.
DISCUSSION
ISSUED AT 200 AM CDT FRI AUG 7 2026
MID-LEVEL HIGH PRESSURE WILL CONTINUE TO DOMINATE THE PERIOD LEADING
TO WARM AND MOSTLY RAIN FREE CONDITIONS OUTSIDE OF ISOLATED
SEABREEZE SHOWERS. SATURDAY LOOKS TO HAVE THE BEST CHANCE OF
PRECIPITATION AS MID-LEVEL VORTICITY RIDING THE PERIPHERY OF THE
RIDGE WILL MAKE ITS WAY INTO SOUTH TEXAS AT THE SAME TIME THAT PWAT
VALUES APPROACH 2.1" ALONG THE IMMEDIATE COASTLINE. HOWEVER, QPF
VALUES FROM ANY SEA BREEZE STORM HAS LOWER CONFIDENCE GIVEN THE
VARIATION OF THE MAX PWATS. WITH THE INCREASED CLOUD COVER OVER THE
WEEKEND, HEAT INDEX VALUES WILL STRUGGLE TO SURPASS THE HEAT
ADVISORY THRESHOLD. HOWEVER, AREAS THAT DON'T EXPERIENCE A SEA
BREEZE SHOWER OR SIGNIFICANT CLOUD COVER MAY EXPERIENCE HEAT INDEX
VALUES OVER 110F. FROM THE START OF THE WORKWEEK, NEAR HEAT ADVISORY
CONDITIONS RETURN WITH INCREASING CONFIDENCE IN THE SPATIAL COVERAGE
OF 110F+ VALUES AND DURATION OF THE PEAK HEAT INDEX VALUES.
