Area forecast discussion, Jun 6, 9:28 AM EDT, 5 hours 10 minutes before
AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE JACKSONVILLE FL 928 AM EDT SUN JUN 6 2004 .PUBLIC...CONVECTION OFF TO ANY EARLY START TODAY AS SCATTERED TSRA MOVE INLAND FROM THE GOMEX ACROSS OUR FL ZONES. THIS ACTIVITY IS BEING GENERATED BY MID LVL SHORT WAVE TROUGH OVER THE FL PANHANDLE AND SWLY FLOW CONVERGENCE ALONG THE COAST. WATER VAPOR IMAGERY SHOWS DRY AIR ALOFT OVER MUCH OF JAX COUNTY WARNING AREA (CWA) AND AN UPR LVL RIDGE AXIS OVER THE WESTERN FL PANHANDLE SLOWLY WEAKENING AS IT APPROACHES OUR WESTERN ZONES. THE MEAN LAYER BERMUDA RIDGE AXIS EXTENDS ACROSS THE FL STRAITS. THE KJAX SOUNDING CAME IN UNSTABLE WITH UNIDIRECTIONAL (SW) FLOW THROUGH 450 MB. TEMPS ARE ALREADY RISING INTO THE UPR 70S WITH DEW PTS IN THE LOWER 70S. PATCHY MORNING FOG IS GRADUALLY BURNING OFF AS INSOLATION INCREASES. FOR THE UPDATE...WILL REMOVE AFTN WORDING IN THE ZONES FOR CONVECTION AND UP TEMPS A TAD BASED ON MOS BEING JUST A DEG OR TWO LWR THAN OBS THE PAST COUPLE OF DAYS. DRY AIR ALOFT WILL LIMIT CONVECTIVE COVERAGE TO 30-40% WITH THE GREATEST CHC OVER OUR FL ZONES FROM JAX-LIVE OAK WHERE DEEPER MOISTURE RESIDES. EXPECT CONVERGENCE ALONG THE WEST COAST TO GRADUALLY WEAKEN THROUGH EARLY AFTN AS THE BERMUDA RIDGE SLOWLY SHIFTS NWD. THIS WILL VEER LOW LVL FLOW MORE WESTERLY AND SHIFT THE STRONGEST MOISTURE FLUX CONVERGENCE INTO OUR FL ZONES...MAINLY ACROSS THE SOUTHERN TIER. WILL ALSO HAVE A HIGHER CHC ALONG OUR FL EAST COAST ZONES LATE THIS AFTN DUE THE SEABREEZE INTERACTING WITH CONVECTION FROM THE WEST. && .MARINE...NO CHANGES PLANNED TO THE FORECAST. THE KING NEPTUNE (LOCAL CRAFT) REPORTED SSW WINDS 15 KTS ABOUT 12NM OFFSHORE OF MAYPORT AROUND 9 AM AND SEAS 2-3 FT. THIS IS RIGHT ON TRACK WITH THE CURRENT FORECAST. && .JAX WATCHES/WARNINGS/ADVISORIES... FL...NONE. GA...NONE. && ENYEDI/SHASHY
