The January 2025 North American storm complex, unofficially nicknamed Winter Storm Blair by The Weather Channel, is an ongoing significant meteorological event that produced a tornado, an ice storm, a blizzard, and a winter storm coupled with an arctic blast that impacted the northwestern United States, southwestern Canada, the Great Plains, and the Midwest region.

Beginning on January 3, 2025, the system first made landfall along the northern West Coast of the United States before tracking southeastward, bringing severe winter conditions to multiple regions and prompting numerous state emergency declarations. The storm system also produced 2025’s first tornado, which touched down in northern California.
