Timeline, snowfall projections show more wintry weather in store for Chicago in coming days – NBC Chicago
While much of the Chicago area experienced snow accumulation and slick roads on Wednesday, winter conditions for the upper Midwest are only just beginning thanks to a rampage of weather disturbances that threaten to produce more snow in the near future.
Due to Wednesday’s weather system, parts of NBC viewing area 5 in northern Illinois and northwestern Indiana reported between 3 and 4 inches of snowfall, with heavier totals in Will and DuPage counties locally.
Even with that in mind, the Chicago area could still see some measurable snow all weekend and even next week.
Here’s what we know so far, and residents are reminded that forecasts can change.
Forecast models say remnants of the disturbance that brought snow accumulations to the region are likely to last through the morning, especially in northeastern Illinois and most of northern Indiana.
Snowfall probably won’t be too heavy, but can cause slippery roads.
By the time all is said and done, another half inch of snow could fall in most places, though areas closer to the lake may see some lake improvement due to the warm water temperatures on Lake Michigan.
Another flurry of snow may be arriving Friday morning, though with southerly winds there will be no improvement in Lake Michigan to boost accumulations.
Light dust is expected in most places, though parts of the far northern suburbs may see nearly an inch of snow.
A much larger disturbance is expected Saturday morning, spreading snowfall across northern Illinois as it moves through the upper Midwest.
Some areas on the southern side of the system may experience mixed precipitation or even rain, as temperatures south of Interstate 80 are likely to hover around freezing.
This snow is expected to persist as the disturbance slowly slides through the region, with winds turning away from Lake Michigan and potentially giving the system some extra fuel to boost snowfall totals.
During Saturday and Sunday, between 3 and 5 inches of snow may fall in areas north of Interstate 80, with locally heavier totals possible in some locations.
South of interstate snowfall totals are likely to be lighter, with 1-2 inches of additional accumulation possible under current models.
Monday and Tuesday
More snow may fall in the region on Monday, with winds still blowing from Lake Michigan bringing a few more packs.
Just in case residents think they’re done with the snow Monday morning, extended forecast models show yet another system moving through the Midwest on Tuesday, bringing mixed precipitation to southern Illinois. and even more snow in parts of Northern Illinois and Northern Indiana.
