December 22-26, 2022 Cold Arctic Outbreak

A large and deepening longwave trough over Central and Eastern North America allowed for a strong Arctic airmass over Alaska and Canada to plunge southward across the Central and Eastern U.S. during December 21-25, 2022. This brought the coldest December temperatures to our region in 33 years, only with the Great Arctic Outbreaks of December 1983 and December 1989 having colder temperatures around the same time of year. The coldest temperatures occurred the morning of December 23rd, with readings ranging from the lower teens across Inland Southeast Texas and Central Louisiana, with mid-teens to near 20 degrees further south. This, coupled with the winds of 20-30 mph, with gusts over 40 mph, made the wind chill temperatures in the single digits, and some locations, negative single digits. Temperatures in the upper teens to lower 20s continued Christmas Eve and Christmas mornings, with moderating temperatures on December 26^th.
