With rain and snow possible this weekend, here’s a timeline of what you might see and when – NBC Chicago

While it looks like the Chicago area will see some precipitation this weekend, exactly what we’ll see remains up in the air.

If it is snowing, the accumulation will likely vary widely – depending on where you live.

Here’s a timeline of what could happen and when weather-wise.

Friday night

Snow showers ended for the majority of the Chicago area Friday night following a fast-moving mower system that dumped snow in some areas, leading to hazardous conditions and heavy accumulations along the Illinois-Wisconsin border.

While the evening saw temperatures in the mid-30s, colder conditions are expected to set in overnight. Temperatures are set to drop into the teens as a band of snow moves east toward Chicago, according to NBC 5 Storm team chief meteorologist Brant Miller.


Although you may see some sun Saturday morning, make no mistake.

Snow accumulation is a possibility later, but so is rain, depending on which forecast model you’re looking at.

The high-resolution rapid refresh model predicts that the storm system will move further north, which means it is more liquid, and therefore will bring rain. The other model, IBM’s High-Resolution Global Atmospheric Prediction System, predicts that the center of low pressure will remain further south, which means more snow.

If the IBM GRAF model is true, parts of Chicago could see snow starting in the afternoon and more than three inches of accumulation through late evening.


If snow does occur, it is expected to continue through early Sunday, with the possibility that Chicago’s snowfall total will reach around 4.5 inches.

However, a much larger buildup could be in store for those along the Illinois-Wisconsin border.

Illinois counties along the border could potentially see 6 to 7 inches of snow, while parts of southern Wisconsin could see up to 9 inches of snow. Snowfall projections are much lower in the western suburbs, with 1 to 4 inches possible.

Some of Chicago’s northern suburbs could see about 4 inches of snow, though that’s likely not the case for all communities, according to the IBM GRAF model. For the most part, 1 to 2 inches of accumulation is expected across most of Chicago.

Those in southern counties are likely to see even less than that, according to forecasts.

If snow falls over the weekend it will likely stay for a while and bring a chance of snow showers on Monday.
