From Larry Cosgrove at Weatheramerica - another potential nor'easter for Halloween with maybe some high ground snows...
"Despite the tendency to have mild weather over much of the U.S. in the short range forecast, the presence of a modest blocking signal over Alaska will have downstream impacts by next weekend. Shortwave energy in central Canada will dig into Appalachia, possibly forming a closed (and cold) 500MB low by November 1. While the operational GFS and GGEM schemes have tended to view this feature as a progressive cold intrusion (bordering on cA character), the ECMWF panels have advertised the formation of a significant surface storm near Cape Hatteras.
Note the Rex signature over Quebec and Labrador after Saturday. If this minor block is for real (and I think that is indeed the case), we may see another Nor'easter with two or three days of wind and rain from Virginia northward to Nova Scotia in the November 1 - 4 time frame. And yes, higher elevations on the western edge of the precipitation shield (do you hear me Interstate 79 and 81 corridors....) could see the first accumulating snow of the season."
