FROM THE HOUSTON METRO TO THE EAST COAST OF FLORIDA.
NOCTURNAL CONVECTION IS EXPECTED TO GET GOING AGAIN THROUGH THE
EARLY MORNING HOURS AND GRADUALLY TRANSITION INLAND DURING THE MID
TO LATE MORNING HOURS. STORMS WILL BE MOST NUMEROUS ALONG THE SEA
BREEZE ONCE AGAIN. AS THE UPPER DISTURBANCE PASSES THE REGION

TX AND CEN LA. WHILE ISOLATED SHOWERS AND STORMS ARE STILL
EXPECTED AT THESE LOCATIONS, COVERAGE WILL BE MUCH LOWER THAN
POINT TO THE SOUTH. APPARENT TEMPERATURES ACROSS INLAND AREAS MAY
ALSO PUSH TO NEAR HEAT ADVISORY CRITERIA IN THE AFTERNOON BEFORE
CONVECTION MOVES IN.
A RIDGE ALOFT BEGINS TO REBUILD OVER THE AREA STARTING SUNDAY.
SCATTERED STORMS WILL REMAIN POSSIBLE ALONG THE SEA BREEZE, BUT
STORMS WILL BE ISOLATED AT BEST ACROSS INLAND AREAS.
HIGH PRESSURE ALOFT BECOMES ESTABLISHED FOR MUCH OF NEXT WEEK.
THIS WILL REDUCE RAIN CHANCES ACROSS THE AREA, HOWEVER A FEW
SHOWERS OR STORMS WILL REMAIN POSSIBLE ALONG THE SEA BREEZE.
