DISCUSSION
ISSUED AT 204 PM CDT SAT AUG 8 2026
A FEW AREAS OF VORTICITY WILL APPROACH SOUTH TEXAS TODAY THROUGH
MONDAY AS THEY RIDE AROUND THE PERIPHERY OF MID-LEVEL HIGH PRESSURE.
THIS, COMBINED WITH PWAT VALUES 1.9-2.1", WILL ALLOW FOR THE
DEVELOPMENT OF SHOWERS AND THUNDERSTORMS TODAY THROUGH MONDAY. FOR
TODAY, HAVE A LOW MENTION OF POPS (~15%), MAINLY ALONG THE AFTERNOON
SEABREEZE. CHANCES INCREASE SUNDAY AND MONDAY AFTERNOONS TO LOW TO
MODERATE (20-40%) AS MOISTURE INCREASES AND THE AREA OF VORTICITY
MOVES CLOSER TO THE AREA. THESE CHANCES WILL MAINLY REMAIN OVER THE
COASTAL PLAINS, WITH MOST OF THE AREA REMAINING DRY. BY TUESDAY,
HIGH PRESSURE BEGINS TO SETTLE IN MORE FIRMLY OVER THE AREA,
EFFECTIVELY ENDING OUR CHANCES FOR PRECIPITATION THROUGH THE
UPCOMING WEEK.
TEMPERATURES WILL CONTINUE TO BE HOT. HEAT INDEX VALUES TODAY AND
SUNDAY WILL GENERALLY BE 105-109; WHILE A FEW LOCATIONS COULD REACH
110-112, WILL NOT ISSUE A HEAT ADVISORY FOR THIS TODAY SINCE THE
CONDITIONS ARE NOT EXPECTED TO BE WIDESPREAD. HEAT INDEX VALUES
INCREASE MONDAY THROUGH NEXT WEEK, WITH HEAT ADVISORIES LIKELY EACH
DAY. THE WBGT RISKS WILL BE HIGH TO EXTREME ACROSS SOUTH TEXAS
THROUGH THE FORECAST PERIOD. PLEASE REMEMBER TO TAKE THE NECESSARY
PRECAUTIONS IF YOU ARE WORKING, PLAYING, OR PRACTICING OUTSIDE:
LIMIT EXPOSURE TO 1-2 HOURS, WITH AT LEAST 4 BREAKS/HOUR (~20
MINUTES TOTAL REST), LIMIT YOUR ACTIVITY LEVELS, DRINK PLENTY OF
WATER, AND WEAR LIGHT, LOOSE CLOTHING.
LOOK BEFORE YOU LOCK!
AVIATION

ISSUED AT 204 PM CDT SAT AUG 8 2026
GENERALLY VFR CONDITIONS EXPECTED THROUGH THE TAF CYCLE. HAVE
INCLUDED A MENTION OF VCSH FOR CRP THIS AFTERNOON, WITH A PROB30 FOR
VCT DUE TO SEABREEZE CONVECTION. THIS COULD BRIEFLY LOWER CEILINGS
AND VISIBILITY TO MVFR. WINDS COULD BE ERRATIC AROUND ANY
THUNDERSTORMS. WINDS WILL INCREASE THIS AFTERNOON, WITH GUSTS TO 20-
25 KT, BEFORE BECOMING LIGHT OVERNIGHT. BRIEF MVFR CEILINGS AND
VISIBILITY ARE EXPECTED FOR ALI AND VCT SUNDAY MORNING BETWEEN 10-
14Z.
MARINE
ISSUED AT 204 PM CDT SAT AUG 8 2026
LIGHT TO MODERATE ONSHORE BREEZES WILL INCREASE TO A MORE MODERATE
BREEZE, WITH PERIODS OF FRESH BREEZES, TUESDAY THROUGH THE END OF
THE WEEK. A LOW TO MEDIUM (20-50%) CHANCE OF SHOWERS AND
THUNDERSTORMS WILL CONTINUE THROUGH EARLY NEXT WEEK.
FIRE WEATHER
ISSUED AT 204 PM CDT SAT AUG 8 2026
MIN RHS WILL BE IN THE 25-35% RANGE EACH AFTERNOON THROUGH THE
WEEKEND IN THE WESTERN BRUSH COUNTRY AND RIO GRANDE PLAINS. THESE
LOW RHS COMBINED WITH ERCS IN THE 70-89TH PERCENTILE RANGE WILL LEAD
TO ELEVATED FIRE WEATHER CONDITIONS OVER THIS REGION EACH DAY. WINDS
WILL GENERALLY BE AROUND 15 MPH, WITH WIND GUSTS IN THE 20-25 MPH
RANGE. A SEA BREEZE SHOWER CANNOT BE RULED OUT THIS WEEKEND THOUGH
WETTING RAIN CHANCES WILL REMAIN LOW.
