DISCUSSION
ISSUED AT 1205 PM CDT TUE OCT 27 2026
TODAY WE MAINTAIN A 15-45% CHANCE OF SHOWERS/THUNDERSTORMS MAINLY
ALONG AND EAST OF I-69C. RAIN CHANCES TAPER OFF TONIGHT INTO
WEDNESDAY WITH ONLY AN ISOLATED CHANCE OF AN AFTERNOON SHOWER OR
THUNDERSTORM. THURSDAY, RAIN CHANCES INCREASE AGAIN ACROSS
NORTHWESTERN PORTIONS OF THE CWA DUE TO EXCESS MOISTURE MOVING INTO
NORTHEASTERN MEXICO AND TEXAS FROM THE REMNANTS OF TROPICAL STORM
VANCE, CURRENTLY LOCATED OFF THE MEXICAN PACIFIC COAST. DRY
CONDITIONS WILL PREVAIL FOR THE REMAINDER OF THE FORECAST PERIOD
OUTSIDE OF A VERY ISOLATED AFTERNOON SHOWER OR THUNDERSTORM.
TEMPERATURES WILL REMAIN SLIGHTLY ABOVE NORMAL WITH HIGHS IN THE
UPPER 80S TO LOW 90S THROUGH THIS WEEKEND WITH LOW TO MID 90S
EXPECTED FOR MONDAY. AT THE VERY TAIL END OF THE FORECAST PERIOD
THERE IS THE POTENTIAL FOR A COLD FRONT TO MOVE THOUGH THE
REGION WHICH COULD COOL THINGS DOWN A BIT.
AT AREA BEACHES THERE IS A HIGH RISK OF RIP CURRENTS THROUGH THIS
AFTERNOON. IN ADDITION, THERE IS A COASTAL FLOOD ADVISORY IN
EFFECT UNTIL 4 AM WEDNESDAY DUE TO THE HIGH ASTRONOMICAL TIDES.
HIGH TIDE IS AT 7:48 PM TONIGHT.
