The episode as NWS BMX wrote it up.
Cold air lurking behind the amplifying trough approached Alabama on January 2nd as the upper trough acquired a negative tilt. Temperatures in the 50s and 60s during the afternoon dropped into the 30s through the course of the evening. An expanding area of rain moved across Central Alabama, with a sharp transition to wintry mix and then to snow along a banded feature that formed in east Mississippi and then tracked eastward across Alabama. Brief periods of heavy snow within the banded feature produced 1-3 inches of accumulation, mainly along and east of I-65 and north of I-20.

NWS Birmingham, AL wrote its last area forecast discussion before the first event at Jan 2, 5:38 PM CST, 5 hours 22 minutes earlier.
