...1828...A severe late freeze followed the mildest winter ever. Temperatures fell to 26 degrees at Six Mile Creek and to 30 degrees on St. John's River near Jacksonville, FL.

...1936...A tornado outbreak in the Deep South resulted in a total of 446 deaths and eighteen million dollars damage (5th and 6th). It was a "Tale of Two Cities". During the evening of the 5th a tornado hit Tupelo, MS killing 216 persons, injuring 700 others, and causing three million dollars damage. The next morning the paths of two tornadoes rated F4 on the Fujita scale, met about 8:30 AM and cut a swath four blocks wide through Gainesville, GA killing 203 persons, injuring 934, and causing thirteen million dollars damage. The business district of the town was almost entirely destroyed as the tornado left a 4 block wide path of destruction in its wake. Eight to ten feet of debris filled the streets following the storm. At least 70 persons died in the Cooper Pants Factory, the greatest tornado toll of record for a single building. (David Ludlum) (The Weather Channel) (Intellicast)
