A series of fast-moving clipper systems have been bringing repeat episodes of light snow to the Chicago area the past few days significantly boosting what had been a record low seasonal snow total to date. The current storm sweeping across the Midwest has the potential to bring the city its heaviest snowfall in more than a year since 5.4 inches fell on January 20, 2012. The storm is expected to deliver 3-6 inches of snow across the north and central portions of the Chicago area with heaviest totals near the lake where lake enhancement may boost totals. Amounts should taper off quickly across the south portions of the area with less than an inch expected. Another round of accumulating snow is due Tuesday, though amounts should be considerably less than Monday’s total. Two more storms are expected to affect the area later this week, though moderating temperatures will likely lead to a wintry mix Thursday and rain over the weekend.
