Area forecast discussion, Apr 8, 8:42 PM EDT, 5 hours 15 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 842 PM EDT WED APR 8 1998 EVEN THOUGH KTLH AND KEVX RADARS ARE NOT DETECTING ANY SIGNIFICANT SHOWERS...AND MOST OF THE SVR WX IS TO THE N OF CWA...I THINK CRNT ZONES STILL LOOK FINE (SINCE WE ARE STILL IN THE WARM SECTOR...AND THE FNT IS WELL TO OUR W). THE ONLY CHANGES I MIGHT MAKE WOULD BE TO CHANGE THE WORDING TO INDICATE THAT THE BULK OF SHWRS/TSTMS WILL OCCUR LATE TONITE. SO...WILL CONTINUE TO MONITOR TEMPS AND RADARS AND WILL UPDATE BIG BEND ZONES LATER IF NECESSARY. MOLLERE
