AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
947 AM EDT SUN MAY 11 2014

.UPDATE...WATER VAPOR IMAGERY SHOWS WEAKENING SHORTWAVE TROUGH
MOVING THROUGH THE LOCAL AREA WITH SOME DRIER AIR WORKING INTO
PARTS OF SRN GA. A WEAK SFC REFLECTION NOTED ACROSS SE GA WITH A
TROUGH LOCATED IN SE GA INTO THE FL BIG BEND AND THIS HAS BEEN THE
FOCUS OF A LINE OF A FEW SHOWERS SINCE EARLY THIS MORNING. RECENT
TRENDS SHOW THE LINE OF SHOWERS HAS WEAKENED AND THIS IS REASONABLE
CONSIDERING THE WEAKNESS OF THE FORCING ALOFT WITH THE SHORTWAVE
TROUGH. HOWEVER...THIS AREA APPEARS TO THE FOCUS OF SOME FURTHER
CONVECTION...LIKELY MORE ROBUST AS THE DAYTIME HEATING GENERATES
DECENT INSTABILITY. THE MODIFIED JAX SOUNDING...IN A CONSERVATIVE
WAY SHOWS SBCAPE OF ABOUT 2100 J/KG AND LI OF -6. THE 500 MB TEMP
IS FAIRLY COOL AT -11C...HAVING COOLED 1-3 DEG SINCE YESTERDAY
ABOVE 650 MB AS THE SHORTWAVE HAS MOVED INTO THE AREA. THEREFORE...A
BETTER SHOT OF SHOWERS AND STORMS TODAY...MAINLY IN THE 20-30% RANGE
OVER THE INLAND AREAS. ANY STRONG STORMS...IF THEY CAN REALIZE
STRONG UPDRAFTS HAVE THE POTENTIAL TO PRODUCE STRONG GUSTY WINDS
AND SMALL HAIL BUT THE THREAT IS LOW AT THIS TIME OWING TO
SUBSTANTIAL CLOUD COVER.

&&

.AVIATION...VFR WITH CIGS ABOVE 12000 FT. SOME VCSH AROUND SSI THROUGH
16Z AND THEN REMAINDER TAFS AFTER 18Z. DUE TO LOW CONVECTIVE CHANCES...ITS
TOO EARLY TO SPECIFY ANY TEMPO GROUPS OR ANY FLIGHT RESTRICTIONS FOR
THIS AFTERNOON/EARLY EVENING ASSOCD WITH ISOLD TO SCT CONVECTION.

&&

.MARINE...LIGHTER SLY FLOW THAN 24 HRS AGO AND SEAS 2-4 FT. WINDS WILL
TURN SELY AS THE E COAST SEA BREEZE DEVELOPS. NO HEADLINES. A FEW SHOWERS
MAY IMPACT THE COASTAL WATERS THROUGH TONIGHT.

RIP CURRENTS: SURF CONTINUES TO BE LOW AROUND 1-2 FT WITH SHORT PERIOD
WIND WAVES WITH PERIODS OF AROUND 6 SECONDS. RIP CURRENT RISK CONTINUES
TO BE GENERALLY ON THE LOW END.
