18+ Inches of Snow for N. Illinois, Wisconsin in the Next 7 Days

UPDATED: Monday, January 8, 2024 at 3:00 pm CST

The National Weather Service has issued a Winter Storm Warning from 8pm tonight (Monday 1/8) through Tuesday night (1/9) at 11:59 pm CST for portions of north central and northeast Illinois, including Rockford.

A Winter Storm Warning will be in effect for most of Northern Illinois and Wisconsin as we prepare for what could be "twin blizzards" according to some forecasts.

Winter Storm Could Continue Through Wednesday Morning

The National Weather Service issued the Winter Storm Watch that will run from Tuesday morning (1/9) through late Tuesday night with a couple of different rounds of snow in the forecast.

On Monday night (1/8), a "quick round of snow" will hit the Rockford region with 1 to 3 inches of accumulation possible which will make travel very difficult. "The hazardous conditions could impact the evening commute," according to the National Weather Service.

Tuesday will bring the most significant snowfall amounts to the Stateline area with the N.W.S. saying there's a potential of snow accumulations reaching over 1 inch per hour late on Tuesday morning into Tuesday evening.

Wind gusts over 30 mph are possible Tuesday during the peak of the storm which could cause blowing snow and whiteout conditions.

How Much Snow Could the Rockford Area Get By Wednesday Morning?

The Weather Channel is predicting up to 3 inches of snow accumulation on Monday night (1/8) from Winter Storm Finn, and the possibility of another 6 or more inches throughout Tuesday (1/9).

Some weather models are showing up to 2 feet of snow accumulating with this storm in parts of northern Illinois and Wisconsin.

With another inch possible on Wednesday, there could be 10+ inches in parts of the Rockford region and Chicagoland area by the middle of the week, but there's potentially even more coming.

Second Winter Storm Could Be Even BIgger Next Weekend

According to the latest extended forecast from The Weather Channel, after Winter Storm Finn dumps nearly a foot of snow on parts of the Midwest and Great Lakes region, another storm could be an even bigger snow maker.

Beginning Thursday night (1/11), there's about a 50 percent chance of flurries when the Weather Channel is predicting about an inch of snow for Rockford.

Friday (1/12) another 4 to 8 inches of snow accumulation is possible before temperatures plummet.

Brutally Cold Temps Will Follow Dual Snowstorms

The latest Weather Channel extended forecast for the Rockford region predicts that high temperatures will only be in the single digits beginning next Sunday, January 14 through Tuesday, January 16.

Once temperatures drop below the freezing mark of 32 degrees this Tuesday night (1/9), the thermometer in Rockford won't get above freezing until at least January 22, according to the Weather Channel.
