MOISTURE HAS MADE A BIG COMEBACK IN EXCEPT FOR AREA W OF WAYCROSS TO LIVE OAK AND TRENTON... ALTHO PWATS ARE NOT INCREASING QUITE AS FAST AS MODELS SUGGEST. ISENTROPIC LIFT COMBINING WITH SBRZ ACTIVITY IS BRINGING SCT TO NUMEROUS STORMS OVER CNTRL FL INTO OUR SRN TIER AND WILL KEEP 50-60% POPS IN THIS REGION. CONVECTION TENDS TO DWINDLE AS IT REACHES THE DRIER AIR IN THE NW PORTION. WILL SEE A RESURGENCE OF RAIN CHANCES ALONG THE E COAST TOWARD MORNING. PATCHY FOG IS POSSIBLE LATE TONIGHT FAR WEST AND NW ZONES WHERE SLIGHTLY COOLER TEMPS IN UPR 60S WILL BE.
