The National Weather Service has released snowfall totals following the winter storm in Lake and McHenry counties, with Woodstock reporting almost 10 inches of snowfall.
A winter storm watch was issued Wednesday morning for Lake, McHenry, Winnebago and Boone counties.
The National Weather Service (NWS) later upgraded the four counties to a winter weather advisory.
Cook, DuPage, Kane, Ogle, Lee and DeKalb counties were also under the winter weather advisory.
The advisory went into effect Thursday afternoon and it expired Friday morning.
Heavy wet snow was reported, with some areas seeing up to almost 10 inches of snow, the National Weather Service (NWS) said Friday.
Air temperatures remained at or just above freezing throughout the entirety of the event across much of northern Illinois and northwest Indiana.
“This made the 6-9″ snow totals that fell across far northern Illinois all the more impressive as, in order to receive notable snow accumulations with these relatively unfavorable temperatures, heavy snow rates needed to be sustained over an extended period of time,” the NWS said.
Snowfall reports from the NWS showed 9.6 inches of snow had fallen between Bull Valley and Woodstock and 9.5 inches was reported northwest of Woodstock.
Harvard saw 9.1 inches and Crystal Lake reported 7.8 inches, the NWS said.
In Lake County, Antioch reported 6.5 inches of snowfall and Lake Zurich and Mundelein saw six inches of snow.
The NWS said three inches fell in Highwood and Bannockburn and 3.6 inches were reported in Buffalo Grove.
