WEAK SHOWERS SHOWING UP ON RADAR. THESE SHOULD DISSIPATE BY EARLY

PERSISTENT SOUTHERLY FLOW AT THE SURFACE AND SOUTHWESTERLY FLOW
ALOFT WILL LEAD TO WARM AND HUMID WEATHER FOR THE MAJORITY OF NEXT
WEEK. HIGH TEMPERATURES TUESDAY THROUGH SATURDAY WILL BE IN THE MID
TO UPPER 80S FOR MOST OF THE AREA WITH MAX HEAT INDICIES IN THE LOW
TO MID 90S. INCREASED RAIN CHANCES ON THURSDAY MAY LEAD TO LOCALIZED
COOLER THAN FORECASTED HIGH TEMPERATURES. OVERNIGHT LOWS WILL BE IN
THE LOW TO MID 70S FOR MOST OF NEXT WEEK WITH PERHAPS A SLIGHT COOL
DOWN HEADING INTO NEXT WEEKEND WITH LOWS IN THE MID TO UPPER 60S.
AN UPPER-LEVEL LOW WILL BE MOVING INTO THE SOUTHERN PLAINS WEDNESDAY
INTO THURSDAY. SOME ISOLATED SHOWERS OR STORMS WILL BE POSSIBLE
WEDNESDAY AFTERNOON IN SE TEXAS JUST THANKS TO INCREASED MOISTURE
AND PVA AHEAD OF THE TROUGH. HOWEVER, RAIN CHANCES INCREASE LATE
WEDNESDAY NIGHT INTO THURSDAY MORNING AS THE ASSOCIATED WEAK COLD
FRONT MOVES INTO THE REGION. SOME UNCERTAINTY ON THE TIMING (COULD
BE AS EARLY AS MIDNIGHT WEDNESDAY NIGHT OR AS LATE AS NOON THURSDAY)
AND HOW FAR THE COLD FRONT MAKES IT INTO THE REGION BEFORE
STALLING/RETREATING BACK NORTH (COULD MAKE IT TO I-10 OR OFF THE
COAST). SOME COOLER/DRIER AIR WILL LIKELY FILTER INTO THE REGION ON
THURSDAY BEHIND THE BOUNDARY, BUT ONSHORE FLOW QUICKLY RETURNS
BRINGING BACK WARM, HUMID CONDITIONS. PASSING WEAK DISTURBANCES
ALOFT MAY TRIGGER ADDITIONAL SHOWERS AND STORMS FRIDAY AND SATURDAY,
BUT COVERAGE IS LOOKING LIMITED AT THIS TIME.
