Wider weather episode

A surface to mid level ridge axis extended across the I-10 corridor Thursday afternoon. There was an early start to convection across SE GA where lingering outflow boundaries spawned initial inland storms over a moist and unstable airmass under west-northwest steering flow. The east coast sea breeze was pinned along the I-95 corridor as the dominant west coast sea breeze shifted inland in the afternoon. Storms zippered southward from Camden/Glynn counties into NE FL as the sea breeze and outflow boundaries converged. Isolated strong storms developed along these boundary collisions producing gusts of 40 to 45 mph along the I-95 corridor. With a saturated airmass and slow storm motion, locally heavy rain of 3 to 4 inches fell in Glynn, Camden and Nassau counties.
