ISSUED AT 1241 PM CDT FRI MAY 1 2026
SHORTWAVE TROUGH IS MOVING INTO EAST TEXAS BEHIND AN ACTIVE JET
FEATURE SITUATED INTO SOUTHEAST TEXAS AND LOUISIANA. THIS FORCING
HAS GENERATED AN AREA OF PRIMARILY SHOWERS, SOME HEAVY, AND
EMBEDDED THUNDERSTORMS. THUNDERSTORMS ARE MORE GENERALLY CONTAINED
TO THE IMMEDIATE COASTLINE WHERE A BETTER STORM ENVIRONMENT IS
LOCATED.
TO THE WEST BEHIND THE DOMINANT COMPLEX, STORMS ARE ELEVATED AND
MORE LIKELY TO PRODUCE OVERRUNNING DOWNPOURS WITH SMALL HAIL.
UNTIL THE MAIN UPPER LEVEL TROUGH AXIS MOVES ACROSS THE REGION,
PERIODS OF SHOWERS WITH MODERATE TO OCCASIONALLY HEAVY DOWNPOURS,
GUSTY WINDS AND PERHAPS A STORM WITH SMALL HAIL, WILL ALL BE ON
THE DOCKET FOR TONIGHT'S FORECAST.
A MUCH COOLER AND DRIER AIRMASS WILL BEGIN ARRIVING LATE TONIGHT
INTO SATURDAY, WASHING OUT REMAINING SHOWERS THROUGH THE MORNING
HOURS. STRONG NORTHEAST WINDS WILL USHER THIS AIRMASS INTO THE
REGION WHICH MAY BRING THE NEED FOR ANOTHER WIND ADVISORY SATURDAY
DURING DAYTIME HOURS.
THERE IS SIGNAL FOR ANOTHER FRONTAL SYSTEM TO MOVE THROUGH THE
REGION TOWARDS THE MIDDLE OF NEXT WEEK. RAIN CHANCES BEGIN
INCREASING LARGELY ON NEXT WEDNESDAY.
