Update 6AM CST…

Snow showers are moving south off Lake Michigan into primarily Lake and Porter Counties in Indiana early this Thursday morning. Additional snow accumulation along with blowing and drifting due to Northerly winds gusting to 30 miles per hour will continue to cause difficult/hazardous driving conditions in that area. The snow should gradually diminish and end later this morning or by midday.


Update 9:30PM CST…

A Winter Weather Advisory (purple-shaded area on map below) is in effect from 3AM to 11AM CST for Lake and Porter Counties in northwest Indiana where lake-effect snow showers/snow plumes are expected to produce 3 to 5-inches of snow creating hazardous driving conditions. Also 1 to 3-inches may occur tonight along and just inland of the Illinois Lake Michigan shoreline in Lake and Cook Counties, including the city of Chicago. Check latest snow formation on the Radar Mosaic below.

Map of Forecast Area


One to three-inches of snow may fall along and just inland of the Illinois and northwest Indiana shoreline tonight into Monday with locally heavier amounts possible. Increasingly difficult driving conditions may develop.

As the center of low pressure moves east into southern Lower Michigan tonight and continues east-bound Thursday, cold air aloft and strong northerly winds on the backside of the departing low pressure will produce plumes of snow showers along the Illinois Lake Michigan shoreline in Lake and Cook Counties tonight gradually curving into northwest Indiana and then persisting in northwest Indiana Thursday morning – primarily hitting Lake and Porter Counties. Snow will then diminish later Thursday, as the winds weaken and become more westerly.
