The first swing in this week's winter one-two punch began Sunday with what's expectd to be 4-7 inches of snow falling across the Twin Cities, soon to be followed by a deep freeze.
As the snow accumulated into the minorng, several metro-area communities declared parking restrictions and Minneapolis and St. Paul Public Schools canceled all classes and activities on Monday. Dozens of other school districts across the state called off classes or announced delayed starts. The Minneapolis-St. Paul International Airport encouraged people to verify the status of their flight as the snow continued.
Once the snow tapers off Monday morning, temperatures will start to plunge Monday night, ushering in at least three days of predicted below-zero weather. The highs are expected to be in the double digits below zero Tuesday and Wednesday, with a slight warm-up to single digits below zero come Thursday.
"I think the proper term is nasty cold," said Tyler Hasenstein, meteorologist at the National Weather Service office in Chanhassen. Though the predictions for the snow accumulation varied on Sunday, he said the concern about the upcoming temperature drop has stayed consistent.
"We are very confident this cold is going to be significant," Hasenstein said. "People are right to be concerned."
The midweek cold spell will rival the frigid February of 1996, which closed schools and challenged septic systems and car batteries. But that didn't come with the 10 to 15 mph winds predicted this week.
Temps on Wednesday could fall to 30 below. With windchill, particularly in rural areas where the wind has more room to build up speed, those numbers could fall to 60 below.
"That means frostbite in a matter of minutes," Hasenstein said.
