Synopsis...
The unseasonably mild temperatures seen on Tuesday will last for one more day Wednesday. A broad area of high pressure will build in for Friday and allow for a beautiful weekend.
Short Term...
Clouds will steadily increase throughout the day on Wednesday as a passing low pressure system to the north and a weak low pressure system to the south make their way through the commonwealth. Areas in the northern tier of the state can expect a few rain showers overnight into Wednesday morning, while some light precipitation is possible in the extreme southern areas. The GFS shows a ridge building in with dry air packed into it, which will bring abundant sunshine to the commonwealth Friday and early Saturday.
Long Term...
The high pressure system will begin receding by Saturday morning. All models are in good agreement that a developing positive-sloped 500mb trough will push this high along and allow for cloud cover to build in over the commonwealth. An approaching low pressure system associated with this trough will likely bring snow showers to the lower half of the state. The low pressure system at this time does not look to be all that strong when it passes through, though as the trough moves east, this system will develop faster once it reaches the eastern seaboard. SE Pennsylvania should keep an eye on this because any veering of this system to the north could help bring a more considerable snow event.
