A weak surface front was near the FL-GA state-line with moist, unstable conditions south of the boundary across NE FL. Diurnally enhanced storms further intensified into the afternoon and early evening as a short-wave trough moved across the area from the west. Storm motion was slow, so locally heavy rainfall was a concern near storm mergers.
