2012-12-20 · near Buoy 41012, Fernandina Beach To St Augustine Fl 20 To 60nm, Atlantic South

Wider weather episode

A pre-frontal squall line moved over the Suwannee River Vally during the evening. Instability was marginal, however low level winds and speed shear were very strong with the 850 mb jet 50-60 knots. A nose of higher instability moved inland from Apalachee Bay and coincided over the Suwannee River Valley, and these convective ingredients phased to produce scattered pockets of wind damage with discrete rotating cells during the evening. Trees were blown down across portions of Suwannee, Hamilton and Alachua counties during this evening.
