MARY KAY KLEIST: And scattered flurries still linger South of I80 for now, but they will be tapering off through the night. Notice how the cloud deck is breaking up too. Skies are clearing around DeKalb, McHenry, Waukegan. Clearing skies are going to take place, and that's going to allow temperatures to fall fast.

So a cold start to your Saturday morning, but sunshine all day long, even though temperatures will be Colder than normal. And then on Sunday, I'm tracking wet snow to move into the picture, and it looks like the timing of this is going to happen around lunchtime of scattered snow showers. Then the accumulation after two o'clock right until about 10 o'clock, and this is looking like it's going to be a very wet snowfall compared to the fluffy stuff we saw the last few times around.

Highest totals will be North of I80, where we will see two to three inches, isolated four. So that's happening on Sunday. With it being a wet snow, that is going to create extra weight on our snow pack. And then after that, we see warming temperatures.

I know it's nice to see some 40s on the extended, but that's also going to generate some problems. Because we could also see some problems on river flooding, and ice jams, and also, falling ice throughout the city, and just that extra weight of that wet snow. So when we time it out in the morning, we start with one below in Joliet, one above in Kankakee, two in Valparaiso.

And by the afternoon, we top out in the mid 20s. We should be at 37, so way colder than normal. 19 in Aurora. Lots of sunshine around, but watch what happens in the evening. Steady temperatures. We stay in the mid 20s, but we bring clouds in ahead of that snowmaker.

Then we're going to see snow showers scatter about at noontime, but really ramp up here in the afternoon and evening. But here's the trick. Look at the temperature, 36 at Midway and Joliet, 35 Kankakee. That rain snow line, the rain wants to move to the North because of all the milder air that's riding in on those southerly winds. So that's why I'm thinking this will be a wet snow instead of the fluffy stuff, and here's the warm front.

So the position of it starts to lift with this system. The low itself is actually going to trek North of us, so that's why I'm only expecting a couple of inches from this. But the reason it's so wet is just because of that push of mild air coming in on the South, so some of our models are giving about an inch and a half on average.

But I am thinking those two to three inch totals, isolated four, certainly possible here when you start heading to the North, especially North of 55 and heading into our North and West suburbs. So that's what we're going to be watching this weekend. Sunshine on Saturday, snow on Sunday. It is a quick mover though. It's out of the way by Monday morning for sure.

Dry, next week. Here's what's interesting, Brad and Erica. Five days above freezing. We haven't done that in a while.

- No, but we have earned it. Haven't we?

MARY KAY KLEIST: Yes.

- Thank you, Mary Kay.
