Cold, Canadian air spilled south into the Southern Plains and Lower Mississippi Valley during January 9th and 10th, ahead of strong high pressure over the Central Plains. Meanwhile, an upper trough traversed the Southern Rockies on the 9th and amplified upon entering the Southern Plains during the early morning hours of the 10th, producing a large swath of heavy snow across much of Western and Central Texas, which eventually moved into East Texas and North Louisiana during the afternoon and evening hours. Snowfall amounts ranged from two to near five inches across much of North Louisiana. These accumulations resulted in treacherous travel conditions across these areas, with the weight of the heavy wet snow contributing to a total of 56,128 customers without power across the AEP SWEPCO service area across East Texas and North Louisiana. An additional 4,300 Cleco customers were also without power across North and Central Louisiana following this winter storm.
