Historic Snowstorm?: Now a Blizzard Watch

More and more the storm that is just beginning to form in the Gulf will become a major snow storm for New England.{ } Jacqui gave a great overview of this storm earlier today.{ } The storm will see the convergence of a weak storm moving from the west, merging with a strong storm/wave from the southeast and becoming a "monster" for New England.{ } Our regional Futurecast nicely captures this sequence in the next two days.{ }

{ }

A blizzard watch is now out for the Boston area.{ }

{ } One of the great tools for forecasting these storms is not any 1 model or simulation of the atmosphere but the ensemble or the simulation of a number of "models".{ } Here is the output of{ }an ensemble from earlier today looks like from the great site at PSU.{ } Not a big threat for us and that red line well to our north suggests any precipitation here{ } would be rain, not snow{ }{ }

And here is the ensemble output of total precipitation for the Northeast by Saturday.{ }

Have friends in Boston and other areas of New England?{ } The dark red region is 3" of precipitation or, if it comes about . . . close to 30" of snow!!{ } Tell your New England friends to get ready and for snow lovers here in the D.C. area . . .well you could still get a flight tomorrow to Boston.{ } But be prepared to be there for many days.
