Up to a foot of new snow and then some across much of the Chicago area Friday

Right on schedule, accumulating snow spread across the Chicago area from the west Thursday evening. By the Friday morning commute, heavy snow falling at a rate of an inch/hour at times was expected to add up to an additional 6 to 10-inches of new snow over the already 4 to 5-inch snow cover we started with on Thursday.

Snowfall will continue Friday and Friday night with storm totals in excess of a foot. Snow should diminish Saturday morning with a break in action until another round of accumulating snow, perhaps 3 to 5-inches hits later Saturday night into Sunday morning. By the time snow ends from the west later Sunday morning, Chicagoans could see snow depths approaching 2-feet in some locations north of Interstate-80.
