Part 9/12:
This cold blast will persist through next Monday and Tuesday, with wind chills making it feel even colder. Canadian regions, particularly, will see harsh conditions, with temperature drops and wind chills making it feel like it's well below zero. The Midwest, Northeast, and Appalachian regions are all expected to endure these brutal conditions, with potential daytime highs in the 40s and 50s, and wind chills falling into the teens and single digits.
