PITTSBURGH (KDKA/AP) — Bitter cold weather has taken hold of much of the northern United States, including Pittsburgh, and is expected to stay put for days to come.

Forecasters are warning of hypothermia and frostbite from arctic air settling in over the central U.S. and spreading east.

The National Weather Service reports International Falls and Hibbing, Minnesota, set record low temperatures Wednesday. International Falls, the self-proclaimed Icebox of the Nation, plunged to 37 degrees below zero, while Hibbing bottomed out at 28 below.

The freezing temperatures and below-zero wind chills come as people in Erie continue to dig out from a storm that has dumped more than 65 inches on the city.

While we’re not dealing with the snow here in Pittsburgh, we are feeling the effects of the frigid temperatures.
