Overview

An extremely cold arctic airmass made its effects felt across Central Alabama beginning on the night of January 5th with the passage of an arctic cold front.  Temperatures fell by almost 30 degrees in a span of 4-6 hours behind the cold front, changing the light rain to a wintry mix of precipitation for a short duration. There were many reports of sleet and light snow reported across the northern half of Central Alabama on the evening of Jan 5th. Howling northwesterly winds also accompanied the arctic airmass with sustained winds of 20-25 mph and gusts upwards to 40 mph at times.  Temperatures struggled to reach the upper teens across the northern counties to the upper 20s across the southern counties on the afternoon of January 6th, with wind chills below zero for counties along and north of Interstate 20. The bone-chilling cold arrived on the morning of January 7th, with low temperatures reported near zero across northern counties to the lower teens across the south.  Record minimum temperatures were broken across the board for every climate site in Central Alabama.
