Hail in Florida, July 19, 2008
Dry air on the west side of Tropical Storm Cristobal interacted with a positive vorticity lobe over the east and west coast sea breeze merger which resulted in isolated severe storms near the Interstate 95 corridor. Model sounding indicated a highly unstable airmass with modified CAPES around 4000 j/kg and Windex values of 44 knots which indicated that some storms could produce gusty winds.
