Area forecast discussion, Jul 11, 8:14 AM EST, 3 hours 46 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 914 AM EDT TUE JUL 11 2006 .SHORT TERM...STARTING OFF THE DAY WITH QUITE A BIT OF SHOWER ACTIVITY OFF THE COAST...MUCH MORE THAN TYPICAL THUS FAR THIS SUMMER. USUALLY THIS IS A GOOD INDICATOR OF ENHANCED POPS INLAND DURING THE AFTERNOON...BUT MORNING SOUNDINGS SUGGEST OTHERWISE. DEEP LAYER DRY AIR REMAINS PREVALENT ABOVE 700 MB AND CERTAINLY NOT MOIST EVEN BELOW THIS LEVEL. PRECIPITABLE WATER VALUE IS LESS THAN NORMAL AT 1.46 IN AND IS CLOSER TO THE NGM AND NAM12 INITIALIZATIONS. HARD TO GO WITH THE NAM12 TODAY HOWEVER...AS DEVELOPMENT OF LOW PRESSURE OFF THE SOUTHEAST FLORIDA COAST LOOKS OVERDONE. WILL INSTEAD BASE THE SHORT TERM FORECAST ON CLIMATOLOGY WITH SHOWERS TO MOVE ONSHORE BY EARLY AFTERNOON...BUT A DECREASING TREND THEREAFTER AS DRY AIR MIXES IN AND REDUCES COVERAGE. ALTHOUGH INLAND COVERAGE WILL BE REDUCED...ISOLATED STORMS MAY BECOME STRONG WITH THE PRESENCE OF GOOD WET MICROBURST PROFILE. OVERALL ZONES LOOK IN GOOD SHAPE AND NO CHANGES PLANNED. && .MARINE...CURRENT FORECAST ON TRACK AND NO CHANGES IN STORE. && .JAX WATCHES/WARNINGS/ADVISORIES... FL...NONE. GA...NONE. MARINE...NONE. && DEESE/TRABERT/KERNS
