TROUGH MOVES OVER THE NEW ENGLAND AND MID ATLANTIC COAST LINE. A
WEAK SHORTWAVE OVER THE GULF WILL CROSS THE FLORIDA PENINSULA TODAY
AND TONIGHT. WITH SURFACE HIGH PRESSURE SPRAWLED ACROSS
FLORIDA...GRADIENT FLOW WILL BE LIGHT ENOUGH FOR A STRONG SEA BREEZE
CIRCULATION TO DEVELOP THIS AFTERNOON. PRECIPITABLE WATER IS
FORECAST TO TOP OUT AT AROUND 1.25 INCHES THIS
AFTERNOON...PREVENTING EXTENSIVE SEA BREEZE CONVECTION TO
DEVELOP...HOWEVER A FEW STORMS WILL BE POSSIBLE OVER THE INTERIOR.

SATURDAY NIGHT THROUGH MONDAY NIGHT AS A DEEPENING TROUGH DEVELOPS

RIDGING IN FROM THE ATLANTIC WITH AN INCREASING SOUTHEAST TO SOUTH
FLOW DEVELOPING LEADING TO A GRADUAL INCREASE IN MOISTURE LEADING TO
THE THREAT OF A FEW AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS
OVER INLAND AREAS AS THE SEA BREEZES MOVE INLAND. FOR NOW HAVE LEFT
20 POPS FOR EACH DAY AS PRECIPITABLE WATER VALUES ARE ONLY FORECAST
TO CLIMB TO AROUND 1.5 INCHES. OVERNIGHT LOWS WILL BE IN THE 60S TO

FOR TUESDAY THROUGH WEDNESDAY THE MID/UPPER LEVEL TROUGH OVER THE

MOVING THROUGH THE SOUTHEAST STATES. THIS PATTERN WILL CONTINUE THE
INCREASE IN SOUTHERLY FLOW BRINGING MORE MOISTURE INTO THE REGION
LEADING TO A FEW SHOWERS AND THUNDERSTORMS WITH BEST CHANCES DURING
WEDNESDAY. TEMPERATURES WILL REMAIN WARM WITH DAYTIME HIGHS MOSTLY
IN THE 80S AND OVERNIGHT LOWS IN THE MID 60S TO LOWER 70S.
