...POTENTIAL FOR LOCALLY HEAVY RAINFALL OVER THE WEEKEND...

.UPDATE...
INCREASING MOIST SOUTHWEST FLOW AHEAD OF APPROACHING SURFACE
TROUGH WILL KEEP RAIN CHANCES HIGHER THAN NORMAL THROUGH THE
OVERNIGHT HOURS. ONE BATCH OF CONVECTION OVER SE GA IS SLOWLY
WINDING DOWN BUT ADDITIONAL STORMS WILL BE POSSIBLE. ONE STORM
STALLED OVER ST SIMONS ISLAND EARLIER THIS EVENING AND DUMPED 4
INCHES OF RAIN IN ONLY AN HOUR AND A HALF. THIS GIVES US A GOOD
INDICATION OF HOW THE TROPICAL AIRMASS THAT IS IN PLACE SETS THE
STAGE FOR A LOCALLY HEAVY RAINFALL POTENTIAL THROUGHOUT THE
WEEKEND...EVEN DURING THE OVERNIGHT HOURS.

SHOWERS AND STORMS ARE ALREADY DEVELOPING NEAR THE GULF COAST AND
THIS ACTIVITY WILL SPREAD INLAND AND AFFECT AREAS GENERALLY ALONG
AND WEST OF THE I-75 CORRIDOR TONIGHT. SOME OF THIS ACTIVITY MAY
SPREAD FARTHER EAST TOWARDS THE ATLANTIC COAST BUT CONFIDENCE IS
MUCH LOWER IN THIS OCCURRING. LOCALLY HEAVY RAINFALL WILL BE THE
MAIN CONCERN. RAIN CHANCES WILL CONTINUE TO INCREASE ON SATURDAY
AS ACTIVITY BUILDS TOWARDS THE ATLANTIC COAST DURING THE DAY.

&&

.AVIATION...
MAINLY VFR CONDITIONS WILL CONTINUE OVERNIGHT. MID AND UPPER LEVEL
CLOUD DEBRIS FROM AFTERNOON CONVECTION IS EXPECTED TO INHIBIT ANY
SIGNIFICANT FOG FORMATION OVERNIGHT. SHOWERS AND STORMS MOVING IN
OFF THE GULF OF MEXICO AND WE WILL NEED TO MONITOR

&&

.MARINE...
SOUTHWESTERLY WINDS WILL DOMINATE INTO EARLY NEXT WEEK AS A COLD
FRONT STALLS JUST NORTH OF THE AREA. NOCTURNAL WINDS SURGES ARE
EXPECTED TO PRODUCE SCEC CONDITIONS OVER THE OFFSHORE LEGS TONIGHT
AND POSSIBLY AGAIN SATURDAY NIGHT AND SUNDAY NIGHT.

RIP CURRENTS: LOW RISK.
