IN THE MID/UPPER LEVELS, A BLOCKING RIDGE OVER THE SOUTHWESTERN US
WILL HOLD IN PLACE THROUGH THE REST OF THE WEEK, WHILE A BROAD
TROUGH LINGERS OVER THE EASTERN US. AT THE SURFACE, THE SUB-
TROPICAL RIDGE IS EXPECTED TO STRETCH FROM THE WESTERN ATLANTIC
ACROSS THE FLORIDA PENINSULA THROUGH THE WEEK, WHILE A STALLED
FRONTAL BOUNDARY HOLDS NORTH OF THE STATE. THIS PATTERN WILL FAVOR
DEEP MOISTURE BUILDING ACROSS THE FORECAST AREA TODAY AND
WEDNESDAY AND HOLDING IN PLACE THROUGH THE REST OF THE WEEK AND
INTO EARLY NEXT WEEK. FOR TODAY, ISOLATED TO SCATTERED SHOWERS
AND STORMS ARE FORECAST TO DEVELOP FROM AROUND THE TAMPA BAY AND
I-4 CORRIDOR SOUTH, WITH MORE NUMEROUS STORMS EXPECTED OVER THE
NATURE COAST COUNTIES TO THE NORTH. UNDER THE INCREASING MOISTURE
TO THE SOUTH OF THE FRONTAL BOUNDARY, RAIN COVERAGE WILL BECOME
MORE WIDESPREAD WEDNESDAY AND THURSDAY, WITH THIS RELATIVELY WET
PATTERN FORECAST TO HOLD THROUGH THE WEEKEND AND INTO EARLY NEXT
WEEK.
OTHERWISE, TEMPERATURES WILL REMAIN NEAR TO SLIGHTLY ABOVE NORMAL,
WITH AFTERNOON HIGHS IN THE UPPER 80S TO MID 90S.
