Severe cold throughout the state is having an impact, starting with a Duluth area ski resort closing Sunday because of "extremely low temperatures and intense windchill factors."

Windchill readings ranging from 20 to 35 below zero "will continue today and tonight" for the Twin Cities area, and much of central and southeastern Minnesota, according to the National Weather Service (NWS).

Coming Monday, the NWS adds, light snowfall is forecast generally along and south of the Interstate 94 corridor into the Twin Cities. "Moderate to heavy snow" is anticipated across far southern Minnesota, the Weather Service added.

Sunday's daytime high in the Twin Cities will hover just above or below the Big Goose Egg, according to the NWS. Wind speeds of up to 15 miles per hour will push the windchill factor below minus-30.

Tuesday should see a high a few degrees above zero in the metro, but the lows are forecast to remain negative territory through Friday. Also, windchills could plunge Tuesday and Wednesday night to a range between 30 and 40 below, the NWS said.

Spirit Mountain's operators pointed to "guest and employee safety" for their decision to close the slopes and its Adventure Park on Sunday "due to the incoming extremely low temperatures and intense windchill factors. As of 10 a.m. Sunday, the temperature was minus-8, with a windchill of minus-28, the Weather Service reported.
