12z EURO and EPS mean show potential for blocking pattern for an east coast snowstorm, with cold air present, and a coastal storm on the New England coastline, models show potential for winter weather on the 27-29th of November, this could be a long duration event, but it could be rain on the coast.  Right now specifics are not smart to forecast given its still 5 days away in time.  This is still an eternity.  However, models have flipped the pattern in the longer range to a less favorable pattern for cold and snowy chances and instead have a ridge of high pressure over the region.  This could easily change back and forth for the next few days.  Snow is a potential, not the forecast.
