The NWS continues to express a great deal of uncertainty about the storm and that if with good reason: the models show a fairly notable divergence still.
I want to show you a model that is known to be pretty good in the short range. I am not saying it will happen as this model depicts because other models show less snow, but you should know it is well within the realm of possibility. I have been holding back but I think I we could see 6-12″ in parts of Allegheny County. I am sticking with my 3-6″ for now, but please be don’t be caught off guard by this storm. Expect the snow to be wet and heavy and for Laurel Mountains and other ridges to the south I expect wide-spread power outages. I was in that region last weekend and countless tree branches are severely bent as well numerous trees already down.
