Tonight’s NAM has the freezing rain/sleet starting a bit later, into the evening, closer to 6 pm Monday for PHL, earlier to our west.

Still a borderline rain/sleet changing to snow event with very little, if any, accumulation.  Icy conditions is the main issue.

Monday 4 PM:  The precipitation started earlier than I had forecast last night.  Fallling as freezing rain with difficult driving conditions.
