Freezing Drizzle to Snow

Noon Update:  Winter Weather Advisory in effect until 4am Tuesday for Winnebago and Boone counties.  This is in anticipation of the snow coming later this afternoon.  Periods of heavy snow will be possible during the evening commute.  Still looking at around 1"-3", with locally higher amounts possible.

The freezing drizzle has pretty much ended, although there could still be a few slick spots through the remainder of the day.  As we go forward this afternoon our attention will then turn to the chance for snow.  A trough extending northwest from an area of low pressure in southeastern Illinois will move through during the afternoon along with an upper level disturbance.  This will likely provide enough lift in the atmosphere for snow to fall during the evening commute.  Totals across the region should range from 1"-3" with higher amounts possible to the north and east.  We'll continue to watch trends throughout the day and should we need to update we will do so right here.
