Mainly lake-effect snow showers remain in the Chicago area
Update 8:40AM CST…
Lake-effect snow showers continue to move south along and inland of the Illinois Lake Michigan shoreline this Monday morning. Northerly winds will become more northwesterly, shifting the band through Cook and DuPage Counties around the south end of Lake Michigan into northwest Indiana later this morning/early afternoon. The snow showers in this band could still produce an additional inch or possibly two before leaving a given location. Roads, highways, streets and sidewalks will remain snow-covered and slick, so plan on slowed travel and outdoor activities.
Farther inland light snow will diminish to flurries and then gradually end from the west. Total snowfall with this most recent storm system generally look like it will range from 1 to 2-inches south of Interstate-80, 3 to 6-inches along the I-88 and I-290 corridor to as much as 6 to 10-inches in counties adjacent to the Illinois-Wisconsin state line. Bull Valley in McHenry County reported the 10-inch total.
Update 2:30AM CST…
A steady light snow will continue into Monday forenoon across the Chicago area, diminishing slowly from the west with the emphasis shifting to a band of lake-effect snow showers expected to shift south from Lake and McHenry Counties into Cook and DuPage Counties, eventually curving around the south end of Lake Michigan into northwest Indiana later morning into the afternoon.
Snow may still accumulate up to an inch well inland with two to three-inches possible in the counties impacted by the lake-effect snow showers. Roads and sidewalks across much of our area will still remain snow-covered and slick slowing travel/outdoor activities.
Update 4:50PM CST…
Light snow will likely continue across northeastern Illinois and northwest Indiana overnight, with temperatures in the middle 20s allowing additional accumulations of an inch or two, keeping roads and sidewalks slick and snow covered.
Snow will diminish somewhat after midnight with the emphasis Monday morning shifting to a band of lake-effect snow showers swinging south from Lake County, Illinois into Cook County, eventually curving around the south end of the lake into northwest Indiana later morning into the afternoon. Additional accumulations of an another inch or two could occur in those lakeside areas.
Accumulating snow is expected across the Chicago area later tonight and Sunday with heaviest amounts of 2 to 4-inches along and west of Interstate-39 as well as counties adjacent to the Illinois-Wisconsin state line where a Winter Weather Advisory (purple-shaded counties on the headlined map) will be in effect. One to three-inches of snow is forecast for the remainder of the Chicago area. Snow will be steady and accumulate some on less-traveled roads, while main highways will be more apt to be in better shape. If planning travel, be prepared to take a little longer and watch for slick spots.
A weakening low pressure disturbance will ripple across our area from west to east, snow starting over westernmost sections late tonight, spreading east across the remainder of northeast Illinois into northwest Indiana by mid-morning Sunday.
