Rain begin in many areas shortly after 7 p.m.
With lows just in the low 30s - after a high today in the low 40s - treated highways and well-traveled streets seem likely to be more wet than icy, though back roads and sidewalks might present some hazards.
Winds of 10 to 15 m.p.h. could push wind chills down into the 20s overnight, before temperatures rise into the mid 40s Thursday.
The forecast also cites a slight chance of rain or snow from Friday night into Sunday morning - with any snow mostly overnight or early morning - with highs again in the mid 40s.
As Philly.com's weather blog pointed out earlier this afternoon, snow has fallen quite often this month but without much potency.
No powerful weekend storm is mentioned in the National Weather Service forecast, and the Weather Channel (weather.com) points out that the computer model that accurately predicted the recent storm that dumped two feet of snow on Boston, as well as Superstorm Sandy, "continues to favor a scenario that winds up a winter storm too far offshore to have much impact on the United States."
