Elburn, IL measured 2.5 inches of snow from 9 p.m. Monday to 1 p.m. today, according to a trained weather spotter.

Snow accumulation of 1 foot or more is expected throughout much of Kane County and the greater Chicago area through Wednesday afternoon.

Snow accumulation rates will range between 1 to 2 inches per hour, according to the weather service. Snowfall between 10 to 16 inches is likely out west toward Rockford and Dixon. The heaviest snowfall totals, up to 20 inches, are possible downwind of Lake Michigan and in northwest Indiana. 

Whiteout conditions are expected in the evening as large snow and strong winds will persist throughout much of the area, according to the National Weather Service. Motorists should not travel during this period because of blowing snow and poor visibility.

If motorists cannot avoid travel, the weather service advises to bring a winter survival kit. If stranded, remain in your vehicle until help arrives.

Weather and driving conditions deteriorated quickly in the mid- to late afternoon as snow intensified south of Interstate 80 and gradually spread into northern Illinois and across the Wisconsin state line.
