The low was minus 13 this morning in Aberdeen, and it will stay cold the rest of the day.
Temperatures are expected to reach a high of minus 8 in the mid- to late-afternoon today, and it will feel like minus 25 to 45 with the windchill throughout the day, said Travis Tarver, a meteorologist with the National Weather Service station in Aberdeen.
"It'll definitely stay below zero today, that's for sure," he said.
"It could drop a degree or so, but we've probably bottomed out this morning," he said.
A wind chill warning is in effect until 4 p.m. today.
Tarver warned that temperatures were cold enough to cause frostbite within minutes.
"Just make sure you're bundled up. Try to get every exposed area covered up with something to prevent frostbite," he said.
The weather didn't interfere with the flight out of Aberdeen Regional Airport this morning, said Mike Wilson, transportation director. There were no reported electrical outages, said Tom Glanzer, a NorthWestern Energy spokesman.
Temperatures are expected to warm up Friday, with a high around 10, Tarver said.
After that, high temperatures will climb into the 30s throughout the weekend into Monday.
