The weather theme for much of the U.S. the rest of this week and weekend will be bitterly cold temperatures and dangerous wind chills, especially in the Central third of the U.S. This extensive arctic air mass will contribute to a few winter events. Winter Storm Shirley will bring ice and snow from the southern Plains to Mid-Atlantic, Wednesday through Friday, and a secondary winter storm will also impact the West late week.
