A pre-frontal squall line raced eastward across NE Florida and SE Georgia during the late evening hours producing wind damage across the Suwannee River Valley. A strong embedded storm produced a brief EF1 tornado in Lawtey, then the rear-flank downdraft descended and the resultant outflow cut-off the tornado circulation and produced a derecho wind event with winds of 60-80 mph that raced across northern Clay county, southern Duval county and northern St. Johns county between 10 pm and 11 pm on Feb. 7th. Another very weak and brief tornado was reported in central St. Johns county associated with another storm cells embedded within the squall line. Very cold upper level temperatures aided in strong downburst formation as well as dry air in the mid levels. The cold pool produced a 23 deg temperature drop between 10 pm and 1030 pm in Keystone Heights Florida.
