D.C. will miss a huge snow storm but not New England.
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.
