At least 10 people -- including a college student and Indiana police officer -- are dead as a result of the bitter, record-breaking deep freeze brought on by the polar vortex that's slammed the Midwest most of the week.

Though the National Weather Service said temperatures will "slowly begin to moderate," the bone-chilling cold on Thursday still shuttered schools and caused the U.S. Postal Service to suspend mail delivery in several states. Wind chills of negative 45 degrees Fahrenheit were reported Thursday morning in International Falls, Minnesota and minus 23 degrees in Minneapolis. Des Moines, Iowa reported a bitterly cold wind chill of minus 25 degrees and Chicago had a wind chill of negative 41 degrees just before sunrise.

"The intense cold and wind that has gripped the Midwest, Great Lakes, and Ohio River Valley will begin moderating later this afternoon and evening," Fox News Senior Meteorologist Janice Dean said Thursday. "Wind chill warnings remain in effect through the afternoon."

Temperatures on Friday and into the weekend will "rise considerably" in the Midwest, giving the region some relief, according to Dean. The blast of polar air that enveloped much of the Midwest from Tuesday through Thursday snapped rail lines, canceled hundreds of flights and strained utilities -- and led to at least 8 deaths across the region.

Here are the victims so far of Polar Vortex 2019:

University of Iowa student Gerald Belz

A pre-med student at the University of Iowa was found behind an academic building on the Iowa City campus just before 3 a.m. by campus police on Wednesday died after he was rushed to the hospital.

Belz's father, Michael, told CBS2/FOX 28 that authorities told them that "zero alcohol was found in his system."

He also told KCCI-TV that his son, who graduated from Cedar Rapids Kennedy High School, wanted to be a cardiologist.
