CRYSTAL LAKE – After a mild December, the McHenry County area will feel a blast of winter weather this week, as arctic temperatures and a snowstorm are expected to sweep through the county.
The first significant snowfall of the season covered portions of the county Sunday with up to three inches of snow and created slick road conditions.
Although the major streets were clear, snow drifts created slippery conditions along side streets, primarily throughout the western parts of the county, said McHenry County Sheriff's Sgt. Porfirio Campos-Cruz.
The storm, which ended late Sunday afternoon, is expected to give away to freezing temperatures Monday morning. Temperatures should dip to 28 below zero with the wind chill, said National Weather Service meteorologist Charles Mott.
By around 7 p.m. Monday evening, the snowfall should return and cover areas throughout McHenry County with roughly four inches of snow, Mott said. Other parts around Chicago could see between three to six inches.
The snowstorm should last until Tuesday morning, when temperatures are expected to reach 14 below zero with the wind chill and get even colder Wednesday morning. Temperatures by midweek should reach 29 below zero with the wind chill, Mott said.
As the storm lets up Tuesday morning, wind gusts from the northwest could reach up to 30 mph, making for hazardous road conditions, Mott said.
"It will be a light snow, so there will be a lot of blowing and drifting," he said.
