Here is what CTP had to say about the Sunday Clipper in their morning discussion.
Next feature of note is a fast-moving, digging, wave moving
down the western side of the upper trough. It is plenty cold for
snow as the moisture associated with it arrives on Sunday. It will likely start to produce some snow over the west early in the day if not late Sat night. Since much of the area will be well below 0C at 8H, much of the precip would be snow. Maybe the SE few counties may have mixed precip or rain, since it is coming thru mainly during the daylight hours. But, QPF is decent - roughly 0.1-0.25" by Sunday evening across a good portion of the CWA. If a low can develop along or just off the coast, it could throw some back into the east Sun night or Monday. However, blended guidance keeps the PoPs kind of low, most likely because of the uncertainty of the speed of the system and if it can develop anything significant before moving
off-shore.
