Slight chance of wintry precip tonight

A couple factors to consider here: sky cover through midnight, ground temperature, quickness of precipitation. A short wave currently in the Ohio Valley will move east tonight and just south of the region tomorrow morning. Moisture will be limited with it, so only expecting sprinkles at this time. If the skies can remain clear through about midnight, allowing for radiational cooling, the ground would be cold enough for some accumulation of ice especially on bridges and overpasses. Will have to monitor this for possibly a few morning commute issues, but otherwise not a big deal. There is also a slight chance that a few snowflakes may reach the ground given wet bulb temperatures near freezing.
