Caution urged as up to 5 inches of snow expected for this weekend across McHenry County region

Residents across northeastern Illinois should brace for up to 5 inches of snow this weekend and low wind chills beginning Sunday.

Kevin Birk, a meteorologist with the National Weather Service in Romeoville, said snow began falling before 3 p.m. Friday.

“I think we’re going to see snow for ... several hours through [Friday] evening,” Birk said.

Emergency crews responded to a single-vehicle crash Friday afternoon in unincorporated Woodstock when a Chevrolet four-door sedan rolled over into a pond in the 14400 block of Pleasant Valley Road because of slick roads.

No one was trapped in the car, and the two people inside – a middle-aged man and a boy – were not injured, said Fire Marshal John Burns of the Union Fire Protection District.

The car was totaled, Burns said, although it will remain at the scene because it was snowing too much to haul it out Friday afternoon.

At a certain point, Birk said the snow probably will start to mix with sleet or possibly even freezing rain through Saturday morning.

Temperatures are set to rise above freezing about daybreak Saturday, with mixed precipitation coming through about that time.

“Most of the snow is going to fall [Friday] evening,” Birk said, with the area netting anywhere from 2 to 5 inches Saturday.

It looks like it will be dry Sunday and Monday, Birk said, although it is set to turn much colder.

The high is expected to be in the teens Sunday, and overnight into Monday, lows might be about zero. Wind chills going into Sunday morning are expected to hit minus 20 degrees. And on Monday, the wind chill is expected to reach minus 13 degrees.

When temperatures begin to hit minus 20 degrees, a wind chill advisory goes into effect, where any bare skin can become frostbitten in a matter of minutes.

Birk said these are not particularly safe conditions to be outdoors, especially with exposed skin. However, he said Friday afternoon that it is too early to tell if it will become that frigid.

“If you do venture outdoors, bundle up,” Birk said. “I would recommend you bring your pets indoors; things like that could be harmful to them, as well.”

The Illinois Tollway is operating its full fleet of 196 snowplows to respond to the snowfall across the region, the agency said Friday. In addition, the tollway will have more than 200 staffers and supervisors working each shift.

“We are asking everyone to help out by giving plows the extra room they need to do their work and to allow for increased distance for other drivers to improve travel safety,” Illinois Tollway Executive Director José Alvarez said in a news release. “In addition, roadway conditions will vary as the winter weather moves through the region this weekend, so we are reminding drivers to be prepared for changing conditions and to slow down or move over for any vehicle stopped on the side of the road.”

Drivers whose vehicles become disabled should remain in their cars until help arrives, turn on their hazard lights and dial *999 for assistance from the Illinois Tollway and Illinois State Police, the tollway said.

Drivers will be asked to note the road they are on, as well as their direction of travel and the nearest mile marker or crossroad. For crashes involving property damage only, drivers should report the incident to 630-241-6800, ext. 5042, and continue driving.
