The National Weather Service has issued a hazardous weather outlook through Friday evening in Tinley Park.

Snow will continue through Friday afternoon across northeast Illinois, including Chicago and northwest Indiana, with 1 to 3 inches of snow accumulation. If you’re heading to northwest Indiana, heavy lake effect snow will fall Friday night with accumulations in excess of 6 inches near the lake.

Wind chills are also expected to drop below zero tonight for the first time this winter.

Our friends at the Illinois Tollway have also sent an e-mail blast to news media informing us that tollway's full fleet of 183 plows will be out in force, throughout the Friday afternoon rush hour.

The tollway's Snow Operations Center will manage the systemwide snow response with a focus on the south Tri-State Tollway (I-294/I-80), which is expected to be the most impacted by the snow.
