An ice storm brought slick roads to McHenry County today.
The McHenry County Sheriff's Office reported there were at least two minor vehicle accidents due to the road conditions Sunday afternoon. The National Weather Service issued a freezing rain advisory for McHenry County from 11 a.m. to 7 p.m. Sunday, and later extended it until 9 p.m.
“We had a mix of very little snow that turned into sleet and transitioned over to mainly freezing rain,” Mike Bardou, a meteorologist with the National Weather Service, said late Sunday afternoon. “The bulk of that is starting to exit the northwest part of the metro area.”
For the next couple of hours, the area should expect “lingering freezing rain shower, more scattered than what we’ve seen during the earlier part of this afternoon," he said.
Air temperatures are expected to rise above freezing by early evening, according to the weather warning issued by the weather service. But since soil and pavement temperatures remain below freezing, the precipitation is expected to freeze on contact and result in ice and dangerous travel conditions on untreated roadways and walkways, according to the weather service.
Ice accumulations of up to a couple tenths of an inch are possible.
The National Weather Service warned that freezing rain can cause roads and walkways to become dangerous and ice accumulation on trees and power lines combined with wind gusts of up to 25 mph may cause outages.
Fog is expected to develop throughout much of northern Illinois during the late night, becoming dense in some locations.
The weather service predicts for McHenry County that freezing rain before 9 p.m., followed by rain. The temperature should rise to about 40 by 4 am., with south-southeast winds about 15 mph becoming southwest after midnight, with wind gusts of up to 25 mph.
