Gov. Tim Walz issued an emergency executive order to activate the National Guard on Tuesday and officials urged Minnesotans to prepare — but not panic — as a potentially historic snowstorm barreled into the state.
Cities declared snow emergencies, schools were shifting to remote learning and airlines were scrapping flights at the Minneapolis-St. Paul International Airport ahead of the storm the National Weather Service labeled "extreme."
With 16 to 22 inches of snow predicted to fall from Tuesday night to Thursday afternoon and winter storm and blizzard warnings in effect across much of the state, authorities advised Minnesotans to stay home.
"This is not the time to tempt fate," State Patrol Col. Matt Langer said during a Minnesota Department of Public Safety news conference. "Think twice before you drive."
The storm will arrive in two parts, with the main event expected Wednesday night into Thursday, the Weather Service said.
Warm air flowing north and cold air dropping out of Canada is converging over Minnesota, putting the Twin Cities in "a prime spot" for a major snowfall, said Tyler Hasenstein, a meteorologist with the National Weather Service's Chanhassen office.
"The storm will grab your attention," said Kevin Reed of the state's Homeland Security and Emergency Management division. "Be prepared, but don't panic."
Snow began falling across western Minnesota before noon Tuesday and moved into the metro area just before 3 p.m. Winds gusting between 35 and 50 mph were expected to produce whiteout conditions and create drifts several feet high, the Weather Service said.
