DISCUSSION
ISSUED AT 938 PM CDT FRI SEP 12 2025
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO BE
THE DAILY WEATHER OCCURRENCE ACROSS DEEP SOUTH TEXAS AND THE RIO
GRANDE VALLEY THROUGH THE FORECAST PERIOD. THIS PATTERN WILL BE
THE RESULT OF A FLOW AT THE SURFACE GENERALLY FROM THE EAST, A
RELATIVELY MOIST ATMOSPHERE, DAYTIME HEATING, THE EAST TO WEST
PROGRESSION OF THE SEABREEZE BOUNDARY, AND 500 MB HIGH PRESSURE
THAT WILL BE NEARBY BUT NOT OPPRESSIVE.
TEMPERATURE-WISE, SLIGHTLY ABOVE NORMAL DAYTIME HIGHS AND
OVERNIGHT LOWS WILL BE THE RULE, WITH NO EXTREME VALUES LIKELY. A
HEAT ADVISORY IS NOT EXPECTED TO BE NEEDED ON ANY DAY, AND HEAT
INDICES WILL NOT LIKELY TRIGGER THE NEED FOR A SPECIAL WEATHER
STATEMENT.
FINALLY, ELEVATED SEAS WILL LIKELY PRODUCE AN EXTENDED PERIOD OF A
MODERATE RISK OF RIP CURRENTS AT THE LOCAL BEACHES.

THE POSSIBILITY OF CONVECTION.
MARINE
ISSUED AT 938 PM CDT FRI SEP 12 2025
ELONGATED SURFACE HIGH PRESSURE OVER THE NORTHERN GULF OF AMERICA
WILL BE THE DOMINANT FEATURE ALONG THE LOWER TEXAS COAST THROUGH
THE FORECAST PERIOD. GENERALLY MODERATE WINDS AND SEAS WILL OCCUR,
WITH SMALL CRAFT SHOULD EXERCISE CAUTION AND SMALL CRAFT ADVISORY
NOT ANTICIPATED TO BE NEEDED.
