The pattern is currently not ideal, but CTP mentions snow a few times in their discussion today over this coming week.
.LONG TERM /THURSDAY THROUGH TUESDAY/...
Thursday will start dry, but a weak short-wave will bring light
snow to the western and northern tier for Thursday evening.
There will be a brief break in the precipitation before the next shortwave and PVA moves overhead and brings in the next round
of precipitation by Christmas Eve evening. Temperatures are on
the warm side, so expect mostly rain. However, some wintry mix is possible along the northern tier and at those higher elevations/cooler spots. Precipitation will hold on through most of Christmas day. Expect a wet Christmas instead of a white Christmas as this will be mostly all rain, but it is possible
for some snowflakes to mix in with the rain as the low-pressure
system moves out of the area Christmas night.
Another shortwave will bring an additional round of precipitation for Sunday afternoon and evening. This system
looks to be colder, so there will likely be snow across the northern tier, with a chance of a wintry mix across central Pennsylvania, and a rain/snow mix possible across the southern tier. The low-pressure system will move directly over the
Commonwealth, and the positioning of this system will greatly
determine precipitation type.
At this point, the beginning of next week looks rather unsettled. An upper-level trough is likely to bring another
low-pressure system to the area Monday/Tuesday. Precipitation type at this point is uncertain, but likely a rain/snow mix.
