The episode as NWS LIX wrote it up.
An upper low centered along the Mississippi River between LA and MS tracked southeast across the northeastern Gulf. As many cold core lows do, it substantially lowered mid and upper level temperatures provided an environment with very steep low to mid level lapse rates. Low overall moisture in the atmosphere limited coverage to a few cells but the ones that did produced hail across the Florida Parishes.
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 New Orleans, LA wrote its last area forecast discussion before the first event at Feb 4, 3:29 PM CST, 2 hours 15 minutes earlier.
