A potent pref-frontal squall line crossed the local forecast area during the late afternoon across SE Georgia and continuing eastward exiting the NE Florida Atlantic coast through midnight.  There was very strong speed shear over the local area with strong 0-6km shear around 55 knots, 0-1km helicity over 300 m2/s2, and sufficient CAPE for severe weather. The limiting factor was fairly weak mid-level lapse rates. Widespread wind damage occurred with this line with gusts of 40-50 mph and severe strength bowing segments producing wind damage and gusts of 60-76 mph. A isolated tornado briefly touched down in Waycross.
