AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
200 PM EDT SAT JUN 28 2003

CURRENT...SHOWERS AND THUNDERSTORMS INCREASING IN COVERAGE AS
AFTERNOON HEATING KICKS IN AND MOISTURE SURGES NORTHWARD FROM THE
TROPICS. EXPECT THIS TREND TO CONTINUE INTO THE OVERNIGHT HOURS AS
VORT MAX ASSOCIATED WITH TROPICAL MOISTURE MOVES NORTH THROUGH THE
CWA.

FORECAST GETS TRICKIER ON SUNDAY AS MODELS BEGIN TO DIVERGE. ETA HAS
RELATIVELY NARROW MOISTURE AXIS WHICH IT MOVES INTO SOUTHERN GEORGIA
FOR SUNDAY WITH SLIGHTLY LESS MOISTURE OVER NORTH FLORIDA. GFS KEEPS
BROAD AREA OF DEEPEST MOISTURE ACROSS ENTIRE CWA. AM WARY OF GFS
HANDLE OF TROPICAL SYSTEM SO AM LEANING TOWARDS ETA. WITH THIS IN
MIND BELIEVE HIGHEST POPS TO BE OVER GEORGIA EARLY WITH SEA BREEZE
CONVECTION SETTING UP IN AFTN ALONG EAST COAST.

BEYOND SUNDAY...FORECAST DEPENDS ON FUTURE EVOLUTION OF TROPICAL
BLOB OVER YUCATAN. ETA TAKES THE SYSTEM SLOWLY TOWARDS TEXAS BY
MONDAY...CANADIAN TAKES STRONGER LOW INTO LOUISIANA SUNDAY NIGHT...
AND NOT TO BE OUTDONE...THE GFS DOES BOTH WITH ONE PIECE OF ENERGY
MOVING INTO LOUISIANA TOMORROW NIGHT AND ANOTHER PIECE INTO TEXAS BY
MONDAY NIGHT. NOGAPS APPEARS TO SUPPORT THE CANADIAN BUT NOT NEARLY
AS STRONG. 12Z UKMET LENDS CREDENCE TO THE ETA. FOR FORECAST...WILL
LEAN TOWARDS SLOWER FURTHER WEST SOLUTION. THIS SHOULD KEEP BULK OF
MOISTURE AND FORCING TO THE WEST LEAVING THE SEABREEZE AS THE MAIN
CONVECTIVE TRIGGER EARLY IN THE WEEK. GENERALLY WEST OR SOUTHWEST
FLOW WILL FAVOR EAST COAST AREAS SO WILL HAVE HIGHEST POPS THERE.
LATER IN THE WEEK REMNANT TROPICAL MOISTURE MAY MOVE BACK INTO AREA
ALONG A FRONTAL BOUNDARY KEEPING CHANCE POPS IN THE FORECAST.

MARINE...TROPICAL SYSTEM SHOULD REMAIN FAR ENOUGH WEST NOT TO HAVE
SIGNIFICANT IMPACT ON COASTAL WATERS. NO HEADLINES PLANNED.

FIRE WX...NO CONCERNS.
