THE COMBINATION OF A MID LATITUDE TROUGH REACHING DOWN THE
ATLANTIC COAST AND AN UPPER LEVEL LOW JUST SOUTH OF CUBA HAS
RESULTED IN BROAD TROUGHING ACROSS OUR AREA. THIS ALONG WITH AN
ESSENTIALLY UNCAPPED ATMOSPHERE, NEAR RECORD DAILY PRECIPITABLE
WATER OF 2.26 INCHES, MOIST CONFLUENT FLOW, AND SEA BREEZE AND
CLOUD LINE DEVELOPMENT HAS RESULTED IN SEVERAL ROUNDS OF SHOWERS
AND THUNDERSTORMS ACROSS OUR AREA THIS PAST AFTERNOON AND EVENING.
TROUGHING WILL LINGER ACROSS OUR AREA THROUGH TONIGHT AND DRIVE
FURTHER ROUNDS OF SHOWERS AND THUNDERSTORMS. WILL MAINTAIN LIKELY
CHANCE OF SHOWERS WITH A CHANCE FOR THUNDERSTORMS FOR THE
OVERNIGHT. THERE WILL LIKELY BE A LULL IN THE NEXT FEW HOURS
GIVEN HOW ACTIVE IT WAS EARLIER. EXPECT OVERNIGHT LOWS IN THE
LOWER TO MID 80S WITH DEW POINTS IN THE MID 70S. WINDS WILL RANGE
FROM WEST SOUTHWESTERLY OVER OUR EASTERN ZONES AND NORTHWESTERLY
OVER THE WESTERN ZONES.
