EPS and Euro AI ensemble are interesting. Seems like they hint at overrunning maybe 3-5 of December?
After that the PV tries to sink through Canada while we have the SW US trough. Despite that trough, it would not shock me if there is something Deep South winter briefly before maybe we grab something perhaps the 7th on.
It’s all just sort of speculation, but sometimes the 24hr ensemble mean precip fields can hint at storm tracks.
