.DISCUSSION...SEA BREEZE BECOMING VERY ACTIVE ALONG THE ATLANTIC
COAST ACROSS BROWARD AND PALM BEACH COUNTIES. THE CLOUD COVER THAT
WAS ACROSS DEEP SOUTH FLORIDA THIS MORNING HAS MADE FOR A SLOWER
START ACROSS MIAMI DADE COUNTY. ISOLATED TO SCATTERED SHOWERS AND

SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND
EARLY EVENING WITH A FEW STRONG TO SEVERE THUNDERSTORMS POSSIBLE

PONDING ON ROADWAYS.

AS LOW PRESSURE DEVELOPS ACROSS THE SOUTHERN PLAINS TONIGHT AND
HEADS TO THE NORTHEAST...THE MID/UPPER LEVEL HIGH PRESSURE ACROSS

PRESSURE REMAINS IN CONTROL OF THE REGION. PWATS ARE EXPECTED TO
DECLINE TO AROUND 1.4-1.6 INCHES ACROSS SOUTH FLORIDA FOR TUESDAY

REGION...EXPECT ISOLATED TO SCATTERED THUNDERSTORMS ACROSS THE
INTERIOR WEST AND TOWARDS THE GULF COAST. HIGH PRESSURE IS
EXPECTED TO GET PUSHED TO THE EAST AND SOUTHEAST ON THURSDAY AN
UPPER LEVEL TROUGH DIGS INTO THE MIDWEST AND SOUTHERN STATES. THIS

SOUTHEAST STATES.
