DISCUSSION
ISSUED AT 145 PM CDT FRI JUL 24 2026
DEEP SOUTH TEXAS WILL REMAIN UNDER THE INFLUENCE OF RIDGING ALOFT
THROUGH MOST OF NEXT WEEK, WHICH WILL MAINTAIN THE SUMMERTIME
HEAT AND GENERALLY RAIN-FREE CONDITIONS. HIGH TEMPERATURES WILL BE
FAIRLY CLOSE TO SEASONAL NORMALS TO START THE WEEKEND, BUT A
GRADUAL UPTICK IN TEMPERATURES IS EXPECTED THROUGHOUT THE WEEK
WITH HIGHS AROUND 3-6 DEGREES ABOVE NORMAL FOR LATE JULY. EXPECT
WIDESPREAD AFTERNOON HIGH TEMPERATURES IN THE TRIPLE-DIGITS ACROSS
MOST OF DEEP SOUTH TEXAS NEXT WEEK, WITH THE EXCEPTION BEING
ALONG THE IMMEDIATE COAST AND ALONG THE LOWER TEXAS BEACHES. SOME
AREAS ACROSS THE REGION MAY APPROACH DAILY RECORD HIGHS AND
HIGHEST LOWS AS WELL. PERSISTENT LOW LEVEL SOUTHERLY TO
SOUTHEASTERLY FLOW WILL MAINTAIN ELEVATED HUMIDITY ACROSS THE
REGION, AND THE COMBINATION OF HIGH HUMIDITY AND ABOVE NORMAL
TEMPERATURES WILL RESULT IN HEAT INDEX VALUES RANGING FROM 100-115
DEGREES EACH AFTERNOON. HEAT PRODUCTS ARE LIKELY FOR PORTIONS OR
MOST OF THE REGION NEXT WEEK.
THE COMBINATION OF NEAR-RECORD TEMPERATURES AND ELEVATED HUMIDITY
WILL RESULT IN A MODERATE (LEVEL 2 OF 4) TO MAJOR (LEVEL 3 OF 4)
HEAT RISK NEXT WEEK. WARM OVERNIGHT LOW TEMPERATURES WILL NOT
ALLOW FOR MUCH RECOVERY FROM THE DAYTIME HEAT AND CAN RESULT IN AN
INCREASED RISK OF HEAT-RELATED ILLNESSES. CONTINUE TO PRACTICE
HEAT SAFETY – WEAR SUNSCREEN, LIGHT-COLORED LOOSE-FITTING
CLOTHING, TAKE FREQUENT BREAKS IN THE SHADE OR INDOORS, AND STAY
HYDRATED!
AVIATION
(18Z TAFS)
ISSUED AT 145 PM CDT FRI JUL 24 2026
VFR WILL PREVAIL THROUGH THE FORECAST PERIOD AT ALL TAF SITES.
EXPECT BREEZY SOUTHERLY TO SOUTHEASTERLY WINDS THIS AFTERNOON,
RANGING FROM AROUND 10-15 KNOTS WITH GUSTS UP TO 25-30 KNOTS.
WINDS SHOULD BECOME LIGHT, GENERALLY NEAR OR BELOW 5 KNOTS, LATE
THIS EVENING AND OVERNIGHT. SOME PATCHY FOG CANNOT BE RULED OUT,
BUT CONFIDENCE IS TOO LOW TO WARRANT A MENTION WITH THIS TAF
ISSUANCE.
MARINE
ISSUED AT 145 PM CDT FRI JUL 24 2026
SMALL CRAFT EXERCISE CAUTION CONDITIONS WILL CONTINUE THROUGH LATE
THIS EVENING OVER THE GULF WATERS AND LAGUNA MADRE WITH SOUTHERLY
TO SOUTHEASTERLY WINDS AROUND 15-20 KNOTS AND SEAS AROUND 3-5
FEET. CONDITIONS SHOULD BECOME MORE FAVORABLE OVER THE WEEKEND
WITH LOW WINDS AND SEAS. BY EARLY NEXT WEEK, A TIGHTENING PRESSURE
GRADIENT MAY RESULT IN SMALL CRAFT EXERCISE CAUTION CONDITIONS
EACH DAY FROM LATE MORNING TO EARLY AFTERNOON. OTHERWISE, EXPECT
RAIN-FREE CONDITIONS.
