McHenry County residents awakened to the first measurable snowfall of the season Thursday morning.

Scott Lincoln, senior hydrologist for the National Weather Service in Romeoville, said there were a few unofficial volunteer reports that put the snow at a range of 1 to 2 inches in McHenry County about 7 a.m.

According to the NWS, total snow accumulations for the day were expected to reach 3 to 6 inches, with isolated amounts of 7 inches possible.

Lincoln said there may have been some light flurries mixed in with rain in the middle of the night Wednesday, but the most recent band of snow started around 6 or 7 a.m. Thursday.

"Obviously, if we're getting any snow, take your time, drive slow," Lincoln said. "All the typical stuff."

Lincoln said there is a slight chance of snow Friday night, but it is a lesser chance than Thursday, and there is no measurable accumulation expected.

If there is snow Friday, the worst experts are expecting is a dusting on elevated surfaces, he said.

Thomas Kotlowski, Crystal Lake's deputy police chief, said the department hadn't received an increase in traffic accidents because of the weather as of Thursday morning.

The city was out early ahead of the snow to put salt on the roads, he said.

Mike Magnuson, public works director for Crystal Lake, said crews were dispatched about 1 a.m. Thursday to get the streets plowed and salted before people started going to work.

"We haven't had any significant issues," Magnuson said. "We're going to continue to stay with it throughout the day."

Magnuson said Crystal Lake has about 2,000 tons of salt on hand, and they expect ordering 5,600 tons for this year.

"We order it throughout the winter season as we need it," he said. "We always keep an adequate supply on hand."

Magnuson said city staff begin thinking about winter in August, so this year's snowfall was not a surprise.

"We're already ready come this time of year," he said. "We had all our trucks ready go to, our route drivers assigned."

Tim Farrell, director of public works in Huntley, said the department was prepared for the snowfall because of the weather forecasting services.

"We knew it was coming," he said.

Farrell said crews went out at 5 to 8 a.m., then went back out at 11 a.m. Farrell said on Thursday they were out until 6 or 7 p.m. Thursday.

On Friday, he said, crews would work before rush hour to check on snow drifts and "freeze-back areas," or any residual water that might be on the road from melting snow.

Road temperatures were warm on Thursday, so the salt broke down the snow pretty well, Farrell said.

The village had about 1,000 tons of surplus salt from last year, he said, and has plans to order up to 3,000 more tons.

"We've been pretty good, I think," Farrell said. "We got ahead of it."

McHenry County College closed at 3 p.m. on Thursday. The closure included all campus locations. It will resume operations normally on Friday, however, according to the college's website.

Several municipalities postponed their trick-or-treating hours as a result of the snowy weather.

Marengo, Ringwood and Johnsburg have changed their trick-or-treat hours to Saturday from 3 p.m. to 7 p.m. on Halloween.

Oakwood Hills moved its hours to noon to 4 p.m. Saturday. They originally were from 3 p.m. to 7 p.m. Thursday.
