The McHenry city forecast for total snowfall has increased from 7.5 inches to 8.9 inches.
The Arlington Heights forecast for total snowfall has increased from 2.0 inches to 6.6 inches. Arlington Heights remains under a Winter Weather Advisory but is very close to Lake County/Buffalo Grove which is under a Winter Storm Warning.
WINTER STORM WARNING IN EFFECT FROM 8 PM MONDAY NIGHT TO
12 AM CST WEDNESDAY
The National Weather Service has opted to upgrade to a winter storm warning for northwestern 1/3 to 1/2 of the Chicagoland area, roughly northwest of a line from Streator to Aurora to Waukegan. Guidance has trended toward shorter break in the precip intensity early Tues AM, so for the sake of simplicity have converted the advisory for tonight to just a warning for the duration of the storm.
Through Tuesday night…
Snow, heavy at times, will overspread the forecast area between about 8 pm and midnight. Vast majority of snowfall expected within about a 3-6 hour window. Snowfall rates will likely reach 1 inch per hour in some areas and could approach 2 inches/hour, particularly with any embedded convective elements.
Winter storm warning will be issued for Lake, Kane, LaSalle Counties westward. Winter weather advisories will be in effect tonight into Tuesday morning remainder of northeast Illinois and northwest Indiana.
Snow, heavy at times, is expected to continue northern portions of the area through much of the day Tuesday, though possibly mixed with or changing to rain near the lake.
Weather Radar shows the leading edge of precipitation approaching a line from Burlington to Peoria to Champaign at 2:45 p.m. Monday.
