Thunderstorm Wind in Alachua County, Florida

A large tree was blown down and blocked NW 190th Avenue in High Springs. The time of damage was based on radar data.

A strong pre-frontal squall line of strong to severe storms moved quickly eastward across SE GA and NE FL during the afternoon and exited off the SE GA coast into the Atlantic waters by the late afternoon and offshore of the NE FL coast by the evening. Strong dynamics with this system included a very strong low-level jet of 45-55 knots and 0-6 km shear of 50-70 knots, which along with good lapse rates aloft around 6.5 C/km and high dewpoints into the upper 60s created 500-800 J/KG of CAPE. These ingredients promoted threat of damaging wind gusts of 50-70 mph or greater, hail, and isolated tornadoes within more intense storms embedded within the Squall line.
