What are thoughts on January 23-27 for good snow chances?

i think the period between 23-27 is two weeks away. nwp doesn't have much skill so far out. at least we're not staring down the barrel of a fatty ridge sitting over the SE.

overall ... a ridge-w / trof-e long wave pattern almost always holds promise for snowstorms as long as the wavelength shortens which keeps the storm(s) closer to the coast.
