Wednesday’s 2-9” area snowfall hasn’t settled and another 2-4” is on the way. It’s part of an extraordinarily active pattern which may result in three additional winter disturbances over the coming week. The first arrives with snow toward nightfall in the Fox Valley then spreads into the city proper an hour either side of 6 p.m. The bulk of this system’s snow appears likely to fall in just 6-8 hours, diminishing in Friday’s predawn hours.
Bursts of lake snow Wednesday sent storm tallies to more than 9” Wednesday. Buffalo Grove’s 9.2” was the area’s heaviest followed closely by Lincolnshire’s 9.0”. Both Waukegan and Arlington Heights logged 8” while city snowfalls included 5.5” at O’Hare and 4.6” at Midway. Amounts tapered to 2” in Kankakee County’s Bonfield.
A 3” or greater snowfall Thursday night would mark only the third time since 1884 that December’s opening week has hosted two 3”+ snows.
