The National Weather Service said a very dangerous and life-threatening arctic air mass is expected in the United States this week.
“Back-to-back cold fronts will slice through the eastern two-thirds of the country to deliver one of the coldest arctic air intrusions in recent memory, especially from the Upper Midwest to the Great Lakes and Ohio Valley,” the NWS said. “From Tuesday through Thursday, expect frigid temperatures and bitterly cold wind chills, likely leading to widespread record lows and low maximum temperatures. Be weather smart.”
