A storm system pushing in from the southwest will bring several inches of snow to parts of the area tonight. Winter weather advisories have been posted for the areas seeing the heaviest snow.

Areas further south will see most rain than snow, the cut off from accumulating snow to rain will be sharp. A closer look below:
