More snow is on the way.  The National Weather Service has issued a winter weather advisory from 1 a.m. tonight to noon Wednesday, for a general one to three inches of snow across the region.

The snow is likely to impact the morning commute. We’ll have our own analysis and snowfall map up between 3:30 and 4 p.m., but here’s the NWS advisory text in the mean time:
