Wrap that coat and scarf around you tightly, slip into mittens and cover your head if you must go out today, or you’ll feel winter’s bite.

After cold temperatures during Wednesday morning’s 6-inch snowfall, the National Weather Service expected worse today, with a high of minus 6.

A wind chill warning has been issued until noon Friday for the area. The Weather Service said gusty northwest winds of 10 to 20 mph will produce wind chills around minus 30 degrees much of the day.

That led to all schools in Kenosha County being closed today.

“At 30 degrees below zero, you get frostbitten in 10 minutes,” Wheatland Center School Administrator Scott Huth said after announcing his school’s closing.

Lows tonight could plunge to minus 20 degrees, the Weather Service said, with wind chills pushing minus 45 degrees.

The air hasn’t been this frosty since Feb. 3, 1996, when Kenosha suffered under minus 23 degrees, according to the state Climatology Office. The coldest on record? Minus 31 on Jan. 16, 1982, and minus 29 on Dec. 24, 1983.

January in Kenosha typically has about seven days with temperatures at or below zero.

Friday might have temperatures as high as 5 above and down to 3 above, with a 40 percent chance of snow.

The frigid conditions are expected to ease by the weekend.

Saturday’s temperatures might range from 9 to 22 degrees, with a 30 percent chance of snow. Sunday could have temperatures between 12 and 22, with a 30 percent chance of snow.

County salting and snow removal crews are to be on the road by 7 a.m. today to clear the way for rush hour traffic, said William Schenning, county public works superintendent. However, he warned motorists to watch for possibly slippery roads and drifting snow.

John Prijic, city of Kenosha Streets Division superintendent, expected all city streets to be cleared shortly after midnight this morning. He said about 6 inches of lake-effect snow pummeled the city on Wednesday morning, mostly between 7 and 10:30 a.m.

That snow and high winds along Interstate 94 caused white-out conditions in spots, leading to 36 accidents, with two people injured, on the highway near Highway 158, said Kenosha County Sheriff’s officials. One of those people, in a three-car crash, was taken to a hospital.

Some drivers ended up in ditches in west Kenosha County during the storm.

Also along I-94, a semitrailer jack-knifed in southbound lanes just north of Highway 50, causing those lanes to be closed at Highway 142 then, later, at Highway KR for a time.

Several vehicles crashed into the concrete median along both northbound and southbound lanes of the interstate about 8:30 a.m. because of white-out conditions. Northbound lanes were not closed.

Kenosha police responded to one injury accident, 13 property damage accidents and 37 calls for motorist assistance between midnight Tuesday and 3 p.m. Wednesday.

Prijic said planning and timing were good for city snow removal crews Wednesday morning. He said all equipment was dispatched by 7 a.m. to remove a few inches of accumulated snow. That’s when the heavy lake-effect snow began to pound the city.

Prijic’s estimate of snowfall so far this winter is 61.5 inches, compared to about 35.5 inches for the same time last year. However, early 2008 had extreme snowstorms that brought that winter’s total to an estimated 103.5 inches.

Prijic said the city crew’s goal on Wednesday was to get as much snow off the roads before the subzero temperatures arrived.

“If that gets packed down, it won’t melt for a long time,” he said.
