NOW IN THE LOWER TO MID 80S WITH DEW POINTS IN THE MID 70S. LIGHT
AND VARIABLE BREEZES WILL FIRM UP OUT OF THE SOUTHWEST TO WEST
OVERNIGHT AS A WEAK DISORGANIZED SURFACE LOW LUMBERS EASTWARDS
INTO THE FLORIDA PENINSULA. THIS EVENINGS SOUNDING INDICATED A
SMIDGE OF LOW LEVEL INHIBITION THAT HAS BEEN SUFFICIENT TO KEEP
SHOWER ACTIVITY AT BAY. ABOVE THIS IS AMPLE CAPE WITH
PRECIPITABLE WATER SLIGHTLY ABOVE THE 75TH PERCENTILE FOR THE
DATE. WHILE THE INHIBTION IS EXPECTED TO WEAKEN SOME OVERNIGHT,
IT WILL REMAIN. THIS WITH THE WEAK FLOW SHOULD GENERALLY KEEP
SHOWERS AT BAY. GIVEN THE SUFFICIENT CAPE AND MOISTURE, IT IS
DIFFICULT TO COMPLETELY RULE OUT SLIGHT CHANCE FOR SHOWERS AND

THUNDERSTORMS FOR THE FIRST PERIOD. EXPECT OVERNIGHT LOWS TO
RANGE NEAR 80 WITH DEW POINTS STAYING IN THE MID 70S.
