Weekend’s snowy conditions quiet down Monday until Thursday when more snow, freezing rain is predicted

Northern Illinois hit with upwards of a foot of snowfall predicted by Sunday night, National Weather Service says

The weekend’s snowy conditions are set to quiet down Monday in northern Illinois and through the first half of the week until Thursday, when the National Weather Service has forecasted a strong chance of rain and freezing rain during the day with snow mixed in that night.

The northeastern corner of the state was hit the hardest by this weekend’s snowfall with at least 6 inches of accumulation in the region spanning from Rockford through the counties of DeKalb, Kane, Kendall and Will, down to Kankakee County and inwards towards Lake Michigan as of Sunday morning, according to the National Weather Service.

Communities near the lake reported over 8 inches of snowfall Sunday morning and this is forecasted to increase to as much as a foot by the time things quiet down Sunday night.

Further to the west and southwest, parts of Winnebago County as well as Ogle, Lee, Bureau, LaSalle, Jo Daviess and Whiteside counties saw lighter snow overnight, reporting between 2 and 4 inches of accumulation as of Sunday morning.

A winter storm warning remained in effect Sunday for the entire northern Illinois region, but the warning switched to a winter weather advisory for north-central Illinois as things slowed down there Sunday afternoon.

The National Weather Service forecast predicted snow would gradually tapper off from east to west Sunday evening. Farther east towards the Chicagoland area, light to moderate snow was predicted to continue until around 10 p.m. Sunday night.

Total snowfall across the western Chicago suburbs will range from 7 to 10 inches by the time things start to wind down Sunday evening.

Any additional snowfall into Sunday evening in north-central Illinois will be very light, according to the forecast.

Monday will be partly sunny with occasional gusts of wind of varying strengths predicted across the broader northeastern Illinois region, according to a National Weather Service weekly forecast. Temperatures will drop to the teens Monday night. The north-central Illinois region will enjoy a mostly sunny day, but similar temperatures.

Across northern Illinois, Tuesday and Wednesday will be mostly sunny with temperatures in the upper 20s and low 30s during the day before dropping to the teens Tuesday night and mid-20s Wednesday night.

Snow, rain and freezing rain is in the forecast for Thursday in the northern and north-central regions with cloudy conditions throughout the day and highs in the 30s before dropping to the mid-teens at night.

Friday will be partly sunny, with highs mostly in the mid-20s and a slight chance of snow Friday and Saturday night across the northern portion of the state, according to the forecast. Temperatures are expected to drop significantly going into the weekend with lows in the single digits Friday night and Saturday night. Highs on Sunday will hover in the low teens.
