The 6z GFS & 0z Euro are starting to agree on the general idea for late this week.
Both have a weak lead wave that brings some rain & snow on Thanksgiving. Then a stronger wave right behind it brings heavier precip mostly in the form of snow. The low then jumps to the coast Friday am as it heads northeast.
The GFS overall has a more minor system that brings a stripe of Advisory snow to mainly southeast PA.
The Euro brings Warning level snow to most of CTP, with Advisory amounts in the LSV.
Either way at this point, it appears that a system is likely over the Thanksgiving period, but impacts still need resolved.
