The National Weather Service has issued a Winter Weather Advisory which will be in effect from 4 PM this afternoon, until 2 PM on Wednesday afternoon.
This afternoon will see a rain/snow mixture which is expected to turn to all-snow this evening into the overnight hours.
Total snow accumulation is 2-4 inches, the Service says.
Temperatures will also drop to the 20s by tonight.

I believe the advisory is until 2 AM Wednesday morning and not until 2 PM Wednesday afternoon as stated in the post.
