AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
245 PM EDT MON MAY 4 1998

CLOSED UPPER LOW OVER THE OH VALLEY OPENS UP AND LIFTS NE WITH THE
TROF AXIS OFF THE ATLANTIC COAST BY WEDNESDAY MORNING. THE WEAK
COLD FRONT ASSOCIATED WITH THIS TROF NOW EXTENDS ALONG A LINE FROM
TLH TO JUST EAST OF ABY. AS SUSPECTED EARLIER...LOOKS LIKE MOST
CONVECTION THROUGH THE REMAINDER OF THE AFTERNOON AND EVENING WILL
BE ACROSS SOUTH-CENTRAL GA AND N FL. MAY BE A NEED FOR LOW CHC POPS
OVER EASTERN COUNTIES IN THE BIG BEND AND SOUTH-CENTRAL GA FOR THIS
EVENING DEPENDING ON HOW FAR EAST BOUNDARY MAKES IT IN THE NEXT
COUPLE HOURS...BUT THAT CAN BE DECIDED RIGHT BEFORE ZONE RELEASE
TIME. THE FRONTAL SYSTEM DIES OUT AS IT MOVES EAST BUT SHOULD MAKE
IT FAR ENOUGH TO THE EAST THAT SOME DRIER AIR WILL SPREAD ACROSS
THE ENTIRE AREA DURING THE DAY TUES. OTHER THAN POSSIBLE LOW POPS
IN THE EAST TONIGHT...NO POPS REST OF PERIOD. NO BIG CHANGES IN
TEMPS OTHER THAN COOLER MINS. GUIDNC TEMPS LOOK OK.
