Friday’s freezing rain could bring icy streets before weekend snow

Light rain combined with an arctic blast could glaze roads and sidewalks with a sheet of ice Friday, just before a major winter storm moves into town this weekend.

The freezing rain will develop across the Chicago metropolitan area late Thursday and linger into Friday, mainly north and west of the city, the National Weather Service said.

As temperatures fall, the rain will freeze, leaving roadways and sidewalks slick. The icy conditions could affect the Friday morning and afternoon commutes, the weather service said.

A freezing rain advisory is in effect from midnight until noon Friday for Lake and McHenry counties, the weather service said. Roadways and sidewalks there could see a slippery coating of ice up to a tenth of an inch thick.

Highs on Friday will reach the low to mid-30s with a 50 percent chance of light rain before dropping to a low in the mid-20s, the weather service said.

But the real trouble starts Saturday, when a complicated winter storm ushers rain, sleet, snow or all of the above into the area after midnight. The storm’s course remains uncertain, but several inches of snow could possibly fall in the far northern suburbs, the weather service said.

Saturday carries a 100 percent chance of precipitation, and the snow will continue through Sunday. The city and southern suburbs could also see lesser amounts of snow.

Meanwhile, the same storm could bring heavy rain to northwest Indiana. Forecasters warn small creeks and streams jammed with ice could flood there.
