Round 1 of Tuesday’s winter weather is done — but more snow is on the way.

Heavy, wet snow made it’s way through the portions of of Illinois Tuesday morning. Part of the area saw a rain snow mix while other parts saw mostly rain.

But Round 2 is gearing up and snow accumulations will once again vary depending on location.

A Winter Storm Warning is in effect for Lake, McHenry, Kane, DeKalb, LaSalle counties until 4 a.m..

A Winter Weather Advisory is in effect until 4 a.m. Wednesday for Cook, DuPage, Grundy, Kankakee, Kendall, Lake and Will counties in Illinois and Porter, Newton and Jasper in Indiana.

Snow likely for Tuesday’s evening rush

Temperatures will play a key role in snow accumulations for the rest of Tuesday. Warmer air from Lake Michigan is keeping areas close to the lake warmer and therefore those areas are seeing less snow. But winds will shift Tuesday afternoon and snow could be more widespread by 5 p.m. Snow is expected to fall through the evening hours before tapering off after midnight.

The city of Chicago and nearby area will see about an inch or two inches by Wednesday morning. Areas west including western suburbs could see close to 4 inches by Wednesday morning.

Wednesday should be quieter for the most part with cloudy skies and windy conditions. High: 32.

Winter Weather Travel Impact

As the winter weather sweeps across parts of the state, arrivals at Chicago’s O’Hare International Airport are seeing some delays due to the snow and ice.

A ground stop went into effect at 3:09 p.m. and has since been canceled, but arriving traffic is seeing an average delay of 1 hour and 46 minutes, the FAA says.

Over 100 flights have been canceled at O’Hare on Tuesday while around 39 flights have been canceled ay Midway.

What is expected overnight into Wednesday morning?

A second round of winter weather sweeping across Chicagoland is bringing freezing temperatures, snow and some wind.

The snow is expected to stick around and continue to fall until about midnight on Tuesday before tapering off during the early morning hours.

Chicago and parts of northwest Indiana are excited to see some of the highest snow accumulations by Wednesday afternoon.

Visibility ranges offer an idea of where much of the snow is falling.

While the first round of winter weather did not bring much snow to the city, that could soon change.

Current projections indicate that parts of Chicago could see up to 3 inches of snow, while areas near Lansing and Crown Point could see between 3.7 and 4.0 inches of snow by 4 p.m. Wednesday.

Snow is not expected to continue into the morning hours, but drivers may still face headaches as they deal with the snow and ice that may accumulate overnight.

Visibility ranges offer an idea of where much of the snow is falling.

As of 4 p.m., visibility around Chicagoland has been reduced greatly by the winter weather.

Visibility at O’Hare has been reduced to about half a mile, while visibility at Midway is around 1 mile.

Reaching into Kenosha, visibility is around 1 mile, and farther north, in Racine, visibility is up to about 4 miles.

Visibility in areas south of Chicago are mostly below 1 mile, while areas to the southwest are seeing visibilities of up to 5 miles.

Another chance for snow later this week — plus cold

Tuesday’s weather is not the only wintry system we’ll deal with in the Chicago area this week. The potential for a very windy late week snow system remains real, so do prospects for the winter’s coldest air to date this season which is to sweep into the area this weekend. By Sunday morning, temps here are to have fallen into single digits if not sub-zero in colder locations with wind chills plunging into the 10 to 20-below range.
