Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS JAX wrote it up.
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.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Jacksonville, FL wrote its last area forecast discussion before the first event at Dec 20, 3:00 PM EST, 3 hours 15 minutes earlier.
