While most of northern Illinois saw rain Friday morning, snow fell in McHenry and Lake counties where the National Weather Service predicted 2 to 4 inches.
The two counties – including the towns of Crystal Lake, Algonquin, McHenry, Woodstock, Waukegan, Buffalo Grove, Mundelein and Gurnee – are under a winter weather advisory until 1 p.m.
The advisory warned of a “period of heavy, wet snow” with sharply reduced visibilities and hazardous travel due to slushy snow accumulations at times.
Temperatures were expected to warm above freezing through the late morning and afternoon with road conditions likely to quickly improve as snow ends, the advisory states.
Snow continues this AM generally along & N of I-90 where roads have become at least partially snow covered! A mix of rain/snow is occurring between there & I-88 with mainly all rain south. Snow will switch over to drizzle by early afternoon & continue into the evening. #ILwx pic.twitter.com/dXvmVgib49— NWS Chicago (@NWSChicago) December 9, 2022
