UNSETTLED WILL BE THE THEME THROUGHOUT THE PERIOD. AFTER A
LACKADAISICAL TUESDAY, IN WHICH RELATIVELY LOW PRECIPITABLE WATER
(PW) CONTENT WILL RESULT IN PALTRY RAIN CHANCES, A MORE ACTIVE
WEATHER PATTERN WILL BECOME ESTABLISHED AND PERSIST. THIS WILL BE
DUE TO MORE ROBUST PW VALUES INTERACTING WITH DAYTIME HEATING, THE
EAST-TO-WEST MIGRATION OF THE DAYTIME SEABREEZE BOUNDARY, AND A
SERIES OF DISTURBANCES THAT WILL "RIDGE RIDE" 500 MB HIGH PRESSURE
CENTERED MORE OR LESS OVER NORTHWEST MEXICO.
TEMPERATURE-WISE, THE DAILY THREAT FOR SHOWERS AND THUNDERSTORMS,
ALONG WITH THE ASSOCIATED CLOUD COVER, WILL HAVE A DAMPENING
EFFECT, WITH VALUES MORE NEAR NORMAL FOR THIS TIME OF YEAR.
FINALLY, WITH CONTINUED SLIGHTLY ELEVATED SEAS, A MODERATE RISK OF
RIP CURRENTS IS LIKELY FOR THE BEACHES ALONG THE LOWER TEXAS
COAST.
AVIATION
(00Z TAFS)
ISSUED AT 609 PM CDT MON SEP 15 2025
VFR WILL PREVAIL AT THE AERODROMES THROUGH THE NEXT 24 HOURS.
LIGHT AND VARIABLE WINDS OVERNIGHT TONIGHT WILL BECOME MODERATE
DURING THE DAYLIGHT HOURS OF TUESDAY. A TEMPO HAS BEEN INCLUDED
IN THE TAFS FOR THE POTENTIAL OF CONVECTION AND IS BASED ON THE
HRRR MODEL.
MARINE
ISSUED AT 1005 PM CDT MON SEP 15 2025
ELONGATED SURFACE HIGH PRESSURE OVER THE ENTIRE GULF OF AMERICA
WILL ALSO BE THE DOMINANT FEATURE FOR THE LOWER TEXAS COAST FOR
THE PERIOD. GENERALLY MODERATE WINDS AND SEAS ARE FORECAST FOR
THE LOWER TEXAS COASTAL WATERS, WITH SMALL CRAFT SHOULD EXERCISE
CAUTION AND SMALL CRAFT ADVISORY NOT LIKELY TO BE NEEDED.
