While blizzard warnings were dropped by 4:15 p.m. Wednesday, dangerously low wind chills will remain until noon Thursday, Feb. 13.

The National Weather Service in Grand Forks warned that a high temperature of minus 1 degree on Thursday will be accompanied by wind chills in the range of minus 40 to minus 50 degrees -- which can cause frostbite on exposed skin in as little as 10 minutes.

Following the blizzard that rolled through the Red River Valley on Wednesday, Interstate 29 from South Dakota to Canada was re-opened at 2 p.m. Wednesday, Feb. 12, though drivers were advised by the North Dakota Department of Transportation to remain off the roads.

Road closures on Wednesday were the result of blizzard-force winds that hit the region earlier and stronger than expected, according to a situation report by the National Weather Service in Grand Forks. Less than one inch of snow fell and blowing snow continuee throughout much of the day.

The Herald has named the storm Blizzard DeAnna for DeAnna Carlson Zink, CEO of the UND Alumni Association and Foundation, which had a record-setting year in fiscal 2019, with $67.7 million raised.

The Herald has been naming blizzards since 1990, giving storms alphabetically alternating male/female names in an effort to honor local residents and also to log storms for the sake of history. The Herald generally uses names of people in the news, famous or mythical figures, or those with connections to the Herald.

Named blizzards from earlier this winter were Adam, Brenda and Carl.

Last winter there were seven named storms. The record is eight, during the winter of 1996-97.

The Langdon area saw the lowest temperatures in the region on Wednesday, with a wind chill temperature of 47 degrees below zero. Wind chill temperatures in the Grand Forks area reached about 43 degrees below zero.

Grand Forks Police Lt. Derik Zimmel advised travelers to remain cautious.

"With such a drastic drop in temperature and a little bit of snow, the intersections are extremely icy today, so we urge people to slow down and take a little extra care if they have to drive anywhere," Zimmel said Wednesday. "And don't drive out of town – there's a reason why the major roads are closed out of town. Visibility is basically nothing."

According to WDAY meteorologist Lydia Blume, visibility is not only reduced in town and sheltered areas: In open country it was much worse.

"That's where you have dangerous travel and frequent whiteouts; you can't see a thing," said Blume.
