PRECIPITABLE WATER HAS STARTED TO DIMINISH ACROSS SOUTHEAST TX
LATE THIS EVENING, WITH 1.8 - 1.9 INCHES REMAINING OVER THE
COASTAL ZONES. DEEP MOISTURE CONVERGENCE COULD PERSIST THROUGH
EARLY MORNING, BRINGING THE POTENTIAL FOR A FEW SHOWERS AND STORMS
ALONG THE COAST/COASTAL WATERS THROUGH MID/LATE SATURDAY MORNING.
OTHERWISE, TYPICAL SUMMER-LIKE WEATHER IS EXPECTED TODAY AND
SUNDAY WITH ISOLATED TO SCATTERED AFTERNOON SHOWERS AND STORMS,
PRIMARILY DRIVEN BY THE SEABREEZE. HIGHS GENERALLY IN THE MID TO
UPPER 90S WITH HEAT INDICES IN THE 103 TO 108F RANGE.

THE SOUTHERN PLAINS BEFORE SHIFTING MORE TO THE EAST THROUGHOUT

FROM THE GULF. WITH PERSISTENT WARM AND HUMID SOUTHERLY SURFACE
FLOW, WEAK DISTURBANCES APPROACHING FROM THE GULF, AND SEABREEZE

WEEKEND INTO THE UPCOMING WEEK WITH HIGHS GENERALLY IN THE MID TO
UPPER 90S (INLAND) AND IN THE LOW 90S (COAST).PEAK HEAT INDICES
