After a cold morning of 19 at Philly International we only mustered up a high of 34 despite plenty of sunshine; overnight clouds will take over in advance of a cold front; we will have snow spread from west to east around Midnight and then change over to sleet and then snow by the morning commute as temperatures at the surface slowly rise.
I am thinking that 1-3" will be the normal snowfall potential before a changeover to rain by mid-morning. For this the National Weather Service in Mount Holly has issued a Winter Weather Advisory for the entire region from 3-11am Tuesday. Once the changeover occurs temperatures will rise into the lower 40s and wash whatever wet snow fell in the morning away.
Overnight temperatures will be in the lower 30s so anything wet may refreeze(hence black ice), but Wednesday we'll have a quick system push by with some light rain as highs will be in the upper 40s. Thursday shall be the pick of the week with plenty of sunshine and highs in the lower 50s!
On Friday we have the potential to crack the lower 60s, BUT there will be a vigorous cold front on the way to provide showers and even some gusty thunderstorms by the evening; this gets out of here through the overnight hours and Saturday will be sunny with highs in the middle 50s.
