After a dose of winter weather on Saturday, it appears more will soon be on the way.

By the afternoon, much of the Chicago area received between one and three inches of snow, though some communities reported up to five inches of accumulation. That round moved out in the following hours, but another was supposed to arrive some time late Saturday into Sunday, bringing around an inch of snowfall.

While Sunday won't see nearly as much snow, some flurries are possible, though a relatively calm day is expected. When the work week rolls around, it will start off rather pleasant for this time of year, but things will change later on when snow arrives.

With a winter storm possible in the coming days, here's a breakdown of what you can expect and when, and how much snow you could see outside your window.

Late Monday

Following a relatively quiet day with comfortable temperatures, the first of two winter storms will arrive late Monday.

A winter system will move in from the southwest overnight Monday into Tuesday, bringing a mixed bag of winter precipitation to the region. A rain and snow mixture will fall along the lakefront, while the rest of the area will likely see snow, according to NBC 5 Storm Team Meteorologist Pete Sack.

Tuesday morning

Wet, accumulating snow is poised to blanket a majority of the Chicago area on early Tuesday, with the most snowfall expected in the region's southern counties, according to the National Weather Service. Rainy conditions will persist along the lakefront, and temperatures in the upper 30s may cause rain to convert into snow.

Northwest Indiana, meanwhile, will likely be in a similar situation. According to meteorologists, the storm system is expected to draw up milder air, and in turn, create a mixture of rain and snow for that region.

Elsewhere across the Chicago area, most communities will see anywhere between 1 and 4 inches of snow.

Tuesday afternoon/evening

The rain and snow mix will persist, with continued snowfall in the northern and western suburbs. Peak snowfall rates are expected in both the afternoon and evening, so you'll want to be especially careful if you're driving during that time.

While the southern portion of the viewing area will see snow earlier in the day, rain will arrive after daybreak and continue through the nighttime hours.

Showers are on tap for the majority of Cook County, as well as Northwest Indiana. Rain will likely end as the system exits overnight Tuesday into Wednesday and makes way for more winter weather.

Wednesday

Colder air will move in Wednesday morning, bringing snow to the entirety of the Chicago area. You'll want to get used to the snow for a little while - as it's expected to continue through both the afternoon and evening on Wednesday.

When all is said and done, snowfall totals will likely exceed 7 inches for the majority of the region. The Global Model estimates 7.3 inches of snowfall will blanket the area, while the European model's estimate is slightly higher at 7.6 inches.

Snowfall estimates in some southern communities are even higher, such as Morris, where nearly 10 inches of accumulating snow is possible.

Thursday and beyond

Thursday will bring yet another chance of snow before a dramatic drop in temperatures. Highs are poised to fall into the upper 20s by the time Friday arrives. Prior to the weekend, we'll see temperatures plummet once again.

Highs will drop into the low- to mid-20s come Saturday, when another round of snow will likely arrive.
