An arctic blast of cold temperatures will move into the region on Tuesday night behind an arctic cold front. High temperatures in the lower 20s to upper teens early Tuesday will quickly fall behind the front to below zero across the area on Tuesday night.
Temperatures will then likely remain below zero through Thursday. High temperatures across the area may not go above zero degrees on Wednesday for the first time since January 1994 in many locations. Low temperatures on Wednesday and Thursday morning will be the coldest temperatures the region has felt since February 2015 and could break daily records by several degrees.
From Tuesday evening to Thursday afternoon, winds 10 to 20 mph across the area with gusts to 30 mph will allow for wind chills of 25 to 35 degrees below zero, with some spots in northwest Ohio perhaps getting as cold as 40 degrees below zero. This will allow for life-threatening cold conditions.
