The National Weather Service (NWS) has issued a severe blizzard warning for McHenry County and surrounding areas. The forecast includes several inches of snow and wind gusts up to 45 mph, leading to dangerous travel conditions. This follows a winter weather advisory previously issued for Lake, DeKalb, and Boone counties. Both are in effect from 10 p.m. Sunday through 1 p.m. Monday, significantly impacting the Monday morning commute. Snow accumulations are projected at three to five inches, with possible light ice. The NWS advises against travel and recommends a winter survival kit for necessary travel.
