February 15–20, 2021 North American winter storm

From February 15–20, 2021, a significant and widespread winter storm, also unofficially referred to as Winter Storm Viola by the Weather Channel, or to some as simply The North Texas Freeze, caused major impacts and additional damage across much of the United States, Northern Mexico, and Southern Canada, and worsening conditions already significantly hampered by another destructive winter storm several days prior. The system started out as a winter storm on the West Coast of the United States on February 15, later moving southeast into the Southern Plains and Deep South from February 16–17.
