Accuweather: Big Snows For NYC, D.C. And Philadelphia Next Winter

After last year’s virtual snow shutout, Accuweather predicts southern mid-Atlantic to southern New England will get walloped in the coming winter.

In its winter outlook released today, it forecasts above average snowfall for major I-95 cities including Richmond, Washington, D.C., Baltimore, Philadelphia and New York City.

“The I-95 cities could get hit pretty good. It’s a matter of getting the cold to phase in with the huge systems that we are going to see coming out of the southern branch of the jet stream this year,” forecaster Paul Pastelok said.

But Washington Post team of winter weather experts and long range forecasters at the Capital Weather Gang (CWG) suggest Accuweather’s forecast amounts to a speculative guess, and is about as likely to be wrong as it is to be right.

The principal reason Accuweather favors big mid-Atlantic and I-95 snows is tied to its expectation of the development of a weak-to-moderate El Nino. A weak-to-moderate El Nino it says “feature[s] a strong southern branch of the jet stream across the U.S.” than can join up with the northern branch of the jet stream and produce big East Coast snow storms.

But CWG’s winter weather outlook lead author Matt Ross cautions it’s too early to predict the strength of the El Nino. Furthermore, he doesn’t think a weak-moderate El Nino guarantees big snow production even if it materializes.
