AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
920 PM EDT FRI MAY  2 2003

THE LINE OF WATCH BOXES TO OUR NORTH AND WEST THIS EVENING IS A BIT
UNSETTLING. NUMEROUS LINES OF STRONG/SEVERE STORMS ARE MARCHING
SOUTHEAST THROUGH GA/AL AND THE FL PANHANDLE. IN ADDITION...SPC HAS
ADDED SOUTHEAST GEORGIA TO THE DAY1 SLIGHT RISK AREA. AM HOPING THAT
LOSS OF DAYTIME HEATING WILL GREATLY THE DIMINISH THE STORMS BUT
MODELS SHOW VORTMAX MOVING ACROSS SE GA/NE FL OVERNIGHT WITH SOME
LIFT INDICATED. MODELS DO NOT INDICATE MUCH PRECIP OVERNIGHT BUT
THEY ALSO DONT HAVE A GOOD HANDLE ON ONGOING CONVECTION. ATMOSPHERE
UNSTABLE PER 00Z SOUNDING EVEN AS TEMPS DROP INTO MID 70S THIS
EVENING.

FOR EVENING UPDATE...WILL KEEP POPS UNCHANGED ACROSS GEORGIA BUT
BEEF UP WORDING CONSISTENT WITH SLT RISK. FURTHER SOUTH...THINK
ACTIVITY WILL HAVE HARD TIME GETTING SOUTH OF I-10 SO WILL DROP POPS
FOR SOUTHERN COUNTIES AT UPDATE.

MARINE...CURRENT FCST ON TRACK. NO CHANGES.

.JAX WATCHES/WARNINGS/ADVISORIES...
FL...NONE.
GA...NONE.
