AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
855 AM EDT WED JUL 23 2014

.UPDATE...12Z SOUNDINGS A LITTLE DRIER THAN YESTERDAY...EXCEPT FOR
KJAX AND KXMR STILL SHOWING 2.0 INCH PWATS BUT WITH WATER VAPOR
IMAGERY SHOWING HIGH LEVEL DRYING/SUBSIDENCE SPREADING NORTHWARD
FROM CTRL/SRN FL. THIS SUPPORTS MODEL GUIDANCE SHOWING LESSER
COVERAGE OF AFTERNOON/EVENING SHOWERS/T-STORMS COMPARED TO THE
PAST FEW DAYS... AND CURRENT FORECAST HAS THIS COVERED. CURRENTLY
A FEW AREAS OF LOW CLOUDS AND FOG WHICH SHOULD BURN OFF BY MID
MORNING.

MADE SOME ADJUSTMENT TO HOURLY POP GRIDS TO REFLECT BETTER
TIMING/COVERAGE OF LATE AFTERNOON ACTIVITY AS SEA BREEZES CONVERGE
OVER EASTERN COUNTIES. ALSO LOWERED HIGH TEMPS A DEGREE OR SO
BASED ON BIAS-CORRECTED MODEL GUIDANCE...AND WITH MODELS SHOWING
ONLY SLIGHT INCREASE IN LOW-LEVEL THICKNESS VALUES OVER YESTERDAY
WHEN HIGH TEMPS WERE AROUND 90.  NO OTHER CHANGES PLANNED.

&&

.AVIATION...IFR CONDITIONS AT KVQQ SHOULD BURN OFF QUICKLY. VFR
CONDITIONS SHOWN IN TAFS. NOT MUCH PRECIP IN TAFS YET DUE TO LESSER
COVERAGE EXPECTED...WILL UPDATE FOR 18Z TAFS BASED ON LATEST RADAR/
SATELLITE TRENDS AND THE LATEST HIGH-RESOLUTION MODEL GUIDANCE.

&&

.MARINE...NO CHANGES PLANNED IN NEXT CWF ISSUANCE...WITH HIGH
PRESSURE RIDGE BUILDING ACROSS THE WATERS.

RIP CURRENTS: WILL MAINTAIN MODERATE RISK FOR TODAY DUE TO 2-3 FT
8-SEC EASTERLY SWELL AND MIDDAY LOW TIDE OCCURRENCE.
