Winter weather advisories remain in effect Monday for parts of northeastern Illinois, with lake-effect snow and freezing drizzle possible.
Several inches of snow could fall in northern parts of the Chicago area near Lake Michigan, with accumulating snow and freezing drizzle likely to impact travel in other parts of the region as as the afternoon progresses.
These bands of lake-effect snow are expected to move slowly across parts of Will County and then into northwest Indiana as the evening progresses, with colder weather expected for most of the week future.
Here’s the latest timeline of how things could play out.
Monday afternoon:
Lake effect snow is expected to begin across a large portion of Cook County, including the city of Chicago, Evanston and southern portions of the county.
Parts of Will County could also begin to see snow during this time, with 1 to 2 inches of snow expected during the afternoon commute.
Additionally, gusty winds could further reduce visibility, with gusts up to 25 to 30 miles per hour, according to forecast models.
Areas of Lake County and northern Cook County could see 3 to 4 inches of snow, according to the National Weather Service.
Monday evening:
Snow is beginning to move out of the immediate Chicago area, but lake effect snow is expected to continue in far southern Cook County, eastern Will County and parts of northwest Indiana , including Lake County.
An inch or two of accumulation is possible, with gusty winds also potentially impacting travel in these areas.
On Tuesday night:
Lake-effect snow could persist until dawn Tuesday morning in parts of northwest Indiana, including Porter, Jasper, Newton and LaPorte counties, according to NWS officials.
Tuesday:
Lake effect snow will slowly ease, with most of the area under partly to partly cloudy skies for most of the day, according to the NBC 5 Storm Team.
High temperatures are expected to settle into the mid-20s, slightly below their seasonal averages in the 30s.
Wednesday-Thursday:
Temperatures will drop slightly on Wednesday, with readings in the 20s and low temperatures in the teens across the region.
Thursday should see some clearing and sunnier skies, but temperatures will remain cold, with highs only in the mid-20s.
Friday:
Another chance for accumulating snow appears in the forecast for Friday, with high temperatures in the mid-20s across the region.
It’s not yet clear how much snow will fall, but the storm system heading toward the area could end up impacting most of northern Illinois and northwest Indiana, leaving open the possibility of snow for much of the Chicago area.
