DISCUSSION
ISSUED AT 1009 PM CDT SUN AUG 9 2026
THE KBRO UPPER AIR SOUNDING FROM THIS EVENING INDICATED A
PRECIPITABLE WATER VALUE OF 2.08 INCHES, WHICH SUPPORTED AN EVEN
MORE ROBUST SMATTERING OF CONVECTION EARLIER TODAY ACROSS THE BRO
CWFA. UNFORTUNATELY, A RAPIDLY-WANING MOISTURE CONTENT WITHIN THE
ATMOSPHERE WILL PREVENT ADDITIONAL SHOWERS AND THUNDERSTORMS FOR
MONDAY AND FOR THE REMAINDER OF THE FORECAST PERIOD, WITH DRY
WEATHER PREVAILING.
TEMPERATURE-WISE, DAILY HIGH TEMPERATURES WILL INCH UP A DEGREE
OR TWO EACH SUCCESSIVE DAY INTO WELL ABOVE NORMAL LEVELS. THIS
WILL CAUSE A MODERATE TO MAJOR HEAT RISK ACROSS DEEP SOUTH TEXAS
AND THE RIO GRANDE VALLEY TO BECOME MAJOR TO EXTREME AS THE WEEK
PROGRESSES.
FINALLY, WITH A GRADUALLY TIGHTENING PRESSURE GRADIENT ALONG THE
LOWER TEXAS COAST EXPECTED, A MODERATE TO HIGH RISK OF RIP
CURRENTS AT THE LOCAL BEACHES WILL LIKELY OCCUR DAILY.
AVIATION
(12Z TAFS)
ISSUED AT 627 AM CDT MON AUG 10 2026
MOSTLY CLEAR SKIES AND LIGHT SOUTHEAST WINDS PREVAIL ACROSS DEEP
SOUTH TEXAS EARLY THIS MORNING. LIGHT SOUTHEAST WINDS WILL BECOME
MODERATE TO BREEZY LATER THIS MORNING INTO THE AFTERNOON. WINDS
ARE EXPECTED TO SLOWLY DECREASE LATER THIS EVENING INTO TONIGHT.
VFR CONDITIONS ARE FORECAST FOR THE NEXT 24 HOURS.
MARINE
ISSUED AT 1009 PM CDT SUN AUG 9 2026
THE PRESSURE GRADIENT OVER THE WESTERN GULF OF AMERICA IS EXPECTED
TO BECOME ENHANCED DURING THE FORECAST PERIOD. LIGHT TO MODERATE
WINDS AND LOW TO MODERATE SEAS INITIALLY WILL BECOME MODERATE TO
BREEZY WINDS AND MODERATE TO SLIGHTLY ADVERSE SEAS BEGINNING
AROUND THE MIDDLE OF THE WEEK. SMALL CRAFT SHOULD EXERCISE CAUTION
AND POSSIBLY SMALL CRAFT ADVISORY WILL BE NEEDED WEDNESDAY
THROUGH THURSDAY NIGHT TO ACCOUNT FOR THE ANTICIPATED STRONGER
WINDS AND HIGHER SEAS. MARINE CONDITIONS SHOULD THEN IMPROVE FOR
THE END OF THE WORK WEEK.
