A winter weather advisory has been issued for the entire northern Illinois area ahead of expected snow Thursday into Friday alongside another period of below-zero wind chills.

The National Weather Service issued the winter weather advisory early Thursday morning.

The advisory includes all northern Illinois counties, including Lake and McHenry counties.

The advisory goes into effect at 6 p.m. Thursday and is set to end at 12 p.m. Friday.

Snow accumulations of one to three inches, with an isolated total of up to four inches, are possible, according to the advisory.

The snow is expected to be dry and fluffy and accumulations are expected to be highest near the lake.

Motorists are advised to plan for slippery road conditions. Motorists are recommended to slow down and use caution while traveling.

“While snow will taper off and end late tonight, areas of blowing snow and drifting snow late tonight and Friday morning will continue to result in hazardous conditions,” the advisory said.

Blowing snow will significantly reduce visibility in open areas and drifting snow will keep exposed roadways snow-covered in open areas.

The hazardous conditions could impact the morning commute, the advisory said.

Another period of below-zero wind chills will arrive Thursday evening and continue through Sunday morning, the NWS said.

Considerably milder temperatures will return to the area next week.
