September edition of the CanSIPS is out. My glass half full overview-
Overall it looks less torchy for the winter months than the previous run. For December, not a half bad look, and verbatim just about average temps. At h5 the positive heights in the EPAC are such that the mean ridge is decently placed..close enough for perhaps a +PNA at times. Beyond that the heights shift westward in Jan, but still not a terrible look for the east coast- maybe a gradient type pattern. By Feb the EPAC ridge is a monster, max +height anomalies south of the Aleutians, and whatever winter there was would be over. Up top, December looks like a neutral AO/NAO, Jan a somewhat +AO/NAO, Feb ++AO/NAO. So not much help in the high latitudes.
