243 PM EDT WED JUL 30 2014

.SHORT TERM (TONIGHT-THURSDAY NIGHT)...UPPER TROUGH OVER THE
EASTERN HALF OF THE COUNTRY INTO THE DEEP SOUTH TO HOLD IN PLACE
KEEPING A VERY DRY MID AND UPPER ATMOSPHERE OVER MUCH OF THE
AREA FOR LATE JULY. COLD FRONT TO STALL OVER THE S CENTRAL FL
PENINSULA WITH DEW POINTS IN THE LOWER 60S IN THE NATURE COAST AND
MID 60S IN CENTRAL FL. WITH ALL THE DRY AIR AROUND EXPECT WELL
BELOW NORMAL RAIN CHANCES AND WARM DAYTIME TEMPERATURES. OVERNIGHT
TEMPS SHOULD BE...NOT AS WARM...AS PREVIOUS LOWS AS WELL. HIGHER
20-30 PERCENT POPS OVER SOUTHERN ZONES CLOSER TO STALLED FRONT
AND DEEPER MOISTURE.

.MID TERM (FRIDAY)...
BY FRIDAY THE BOUNDARY WILL HAVE LIFTED NORTH OF OUR REGION WITH
DEEP TROPICAL MOISTURE IN PLACE. PRECIPITABLE WATERS ARE FORECAST
TO BE OVER 2 INCHES WHICH WILL ALLOW AFTERNOON SEA BREEZES TO KICK
OFF SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS AFTER NOON.

.LONG TERM (FRIDAY NIGHT-WEDNESDAY)...
THE WEEKEND LOOKS WET WITH HIGHER THAN NORMAL RAIN CHANCES...
MAINLY DURING THE AFTERNOON HOURS. A DEEP LAYERED RIDGE OVER THE
ATLANTIC WILL BUILD SOUTHWESTWARD TOWARD THE SOUTHERN PORTION OF
THE MID-ATLANTIC COAST. THIS WILL RESULT IN A SOUTHEASTERLY WIND
FLOW WHICH FOCUSES AFTERNOON STORMS ON OUR SIDE OF THE STATE.
ALSO...PRECIPITABLE WATERS WILL REMAIN NEAR OR ABOVE 2 INCHES.

ON MONDAY...THE RIDGE BREAKS DOWN A BIT ALLOWING A BIT MORE
SOUTHWESTERLY FLOW TO DEVELOP. A WEAK UPPER-LEVEL TROUGH WILL BE
IN THE AREA PROVIDING EXTRA LIFT. TIMING IS TOUGH TO PIN DOWN SO
KEEPING THE FORECAST SIMPLE FOR NOW WITH NUMEROUS SHOWERS AND
SCATTERED THUNDERSTORMS THROUGHOUT THE DAY.
