AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
958 PM EDT WED APR 23 2014

.UPDATE...
QUIET WEATHER PATTERN WITH MILD TEMPS THIS EVENING. THE 0Z JAX
SOUNDING SHOWED AN EXTREMELY STRONG SUBSIDENCE INVERSION NEAR 7000
FEET WITH VERY DRY AIR ALOFT. THIS SUBSIDENCE IS SHOWING UP VERY
NICELY ON WATER VAPOR IMAGERY THIS EVENING. NO PRECIP WAS OBSERVED
TODAY AND NONE IS EXPECTED OVERNIGHT. MOSTLY CLEAR SKIES AND CALM
WINDS WILL EVENTUALLY LEAD TO SOME FOG DEVELOPMENT OVERNIGHT. MOST
OF THE FOG WILL BE PATCHY IN NATURE BUT THE HRRR IS SHOWING AN
INCREASED CHANCE FOR FOG ALONG THE I-75 CORRIDOR LATE TONIGHT.
CONDITIONS ARE DEFINITELY FAVORABLE FOR THIS TO PLAY
OUT...ESPECIALLY GIVEN THE HIGHER LOW LEVEL MOISTURE IN PLACE
COURTESY OF THE GULF COAST SEABREEZE. WITH THIS IN MIND...WE HAVE
INCREASED THE FOG WORDING TO INCLUDE AREAS OF FOG ACROSS THE I-75
CORRIDOR REGION. SOME LOCALLY DENSE FOG WILL ALSO BE POSSIBLE
THERE.

&&

.AVIATION...
VFR EXPECTED FOR EAST COAST TERMINALS DUE TO CLEAR SKIES AND LIGHT
WINDS. AREAS OF FOG MOVING INLAND FROM THE WEST COAST WILL LEAD TO
VSBY RESTRICTIONS AT GNV. HAVE MVFR AT THIS TIME...BUT NOW HAVE MORE
CONFIDENCE FOR LIFR VSBY BETWEEN 09Z-13Z AND CIGS BKN002. EXPECT
MVFR AT VQQ AND NO CIGS.

&&

.MARINE...
OFFSHORE WINDS ARE 10-15 KTS OVER THE OUTER WATERS AND 5-10 KTS
NEAR THE COAST. EAST SWELLS ARE CONTRIBUTING TO COMBINED SEAS OF
2 FT NEARSHORE AND 3-5 FT OFFSHORE. WINDS WILL INCREASE AHEAD OF
THE FRONT TONIGHT...BUT SHOULD PEAK BELOW EXERCISE CAUTION LEVELS.
WINDS WILL THEN DECREASE AND VEER TO ONSHORE FOR WEDNESDAY.

RIP CURRENTS: A MODERATE RISK OF RIP CURRENTS IS POSSIBLE AGAIN
ON THURSDAY DUE TO LINGERING EAST SWELLS.
