This is not the best news for the late-day commute: Snow is falling already in parts of Chester and Delaware Counties.
The National Weather Service forecast of 1 to 2 inches hasn't changed -- with an isolated 3 here and there.
Ordinarily, that would be no big deal, but the timing couldn't be much worse. On Fridays, the evening peak commute tends to start a little earlier.
The steadiest snow is forecast to arrive around nightfall and continue into the the early evening, with everything coming to an by midnight.
