A large and amplifying upper trough dug south through the eastern two-thirds of the United States along and east of the Rockies on December 22nd, which ushered in the coldest temperatures for December in decades to much of the country leading up to the Christmas Day holiday weekend. This very cold arctic air mass moved into extreme Southeast Oklahoma, Southwest Arkansas, and Northeast Texas during the morning hours of the 22nd, with temperatures falling sharply some 20-30+ degrees with the attendant cold frontal passage into the single digits and lower teens by the morning hours of the 23rd. Very strong and gusty northwest winds of 35-45 mph were observed behind the front even through the morning of the 24th, producing a long duration of wind chill values ranging from 0 to as low as -10 degrees across North Louisiana from the evening of the 22nd to the morning of the 24th. While the temperatures associated with this arctic air mass were not quite record-breaking for this time of year, the long duration of subfreezing temperatures, which persisted nearly 2 days, resulted in multiple reports of freezing and bursting of water pipes, as well as sporadic power outages across these areas.
