A massive Great Lakes storm system will impact the US sometime in the next 7-8 days from now maybe sooner and will switch the pattern to an EC trough and WC ridge pattern favoring cold and stormy conditions for the Eastern CONUS in the mid to late month time frame.  A massive snowstorm is a potential noise maker come November 12-18th period.  The signal is increasing for a formidable Clipper approaching the EC to come after 10 days.  EURO, GFS both have this system.  Cold temps look to stay prevalent throughout the rest of the month.  Stay tuned
