A weak surface low was located 165 nm east of Daytona Beach with a
diffuse trough extending westward into the Gulf of Mexico where

satellite loop continued to show warming cloud tops as the
precipitation diminishes. Radar was also showing multiple boundaries
scattered across the Gulf from previous convection. The evening

Expected scattered showers and thunderstorms to redevelop offshore
later tonight...then move onshore toward sunrise.
Aviation... VFR currently...but scattered showers in the Gulf of
Mexico expected to move onshore after 09z. Coverage is a tough call
at this time so will keep forecast VFR with vcsh or thunderstorms in the vicinity after 09z.
Marine... large area of light to moderate rain 0 to 60+ miles
offshore from Tarpon Springs to Suwannee River will diminish. A
series of left over outflow boundaries will create scattered showers
