Two upcoming snowfalls threaten to bring more than a foot of snow to some locations in the Chicago area, but exactly what you’ll see with these systems depends on where you live.

Storm Team 5 meteorologists shared what could happen across the Chicago area.

When will the snow start and how long will it last?

Rain is set to begin, possibly rain, Tuesday afternoon as temperatures are expected to soar into the mid-40s. This will mark the start of the first winter system.

Rain is likely to turn to snow soon after sunset as temperatures start to drop. Then snow is expected to develop over the entire Chicago area, heaviest in the south and lightest in the north.

By Wednesday afternoon, the snow is expected to fade to light snow or snowfall, but may not completely end as the first wave moves out.

Another system could follow closely behind the first wave Wednesday night and into Thursday, again largely for areas south of Chicago and northwest of Indiana.

The system could continue to add several inches of snow in some locations through Thursday afternoon, before ending in the evening.

When do weather warnings start?

The National Weather Service announced that LaSalle, Grundy, DuPage, Kendall, as well as areas of Cook and Will counties, will be under a winter storm warning from 8 p.m. Tuesday to 6 p.m. Thursday, due to snowfall. 5 to 11 inches thick is expected to accumulate throughout the area.

In the northern suburbs, 1 to 3 inches is expected.

If the second storm follows a similar path to the first, there’s a chance counties further south could receive a total of 15 inches or more Thursday night, though that total doesn’t count. to compression, this may result in less total appearances.

Meanwhile, counties far north will likely receive 1 to 3 inches or less by the time both systems move out.

For areas along Interstate 80, totals appear to be between 5 and 10 inches.

Winter storm warnings for LaSalle, Grundy, Will and parts of Cook County warn of a possible 5 to 11 inches through Wednesday, although more snow is possible outside the warning window. In DuPage and Kendall, warnings require anywhere between 4 and 8 inches of snow.

In Kankakee County in Illinois and Newton, Jasper, Lake and Porter counties in northwestern Indiana, the warning calls for a cumulative 8 to 12 inches with the first system and an additional 3 to 6 inches from Wednesday night through Thursday.
