Parts of the Chicago area could see several inches of snow as a wintry weather system develops and temperatures plummet Sunday night.
A system of lake effect snow showers will develop tonight and persist through Monday night, bringing with them as much as 5 inches of snow over northwest Indiana, according to the National Weather Service.
Areas around the shoreline from northwest Indiana as far north as Waukegan could also see some accumulation, including downtown Chicago, the weather service said.
Turning windy and colder tonight, with accumulating lake effect snow likely mainly for northwest IN. Gusty north winds also build Lake Michigan waves, and create lakeshore flooding impacts into NW IN too. #ilwx #inwx pic.twitter.com/nreq5IKdS4— NWS Chicago (@NWSChicago) November 29, 2020
The snow showers are expected to taper off in northwest Indiana by Tuesday morning, the weather service said.
Along with the snow, temperatures are expected to dip into the mid to low 30s Sunday night into early Monday morning, the weather services said. Tuesday night temps could get into the low 20s.
The system is also expected to produce strong winds over the lake, and a lakeshore flood warning is in effect along the Cook County shoreline through Monday morning.
