Also, the ETA6 is hitting bermuda so that doesn't help in the opposite way.

Enjoy the rsm and eta solutions while you got them:

SREF

A major upgrade to SREF is planned now for FY11Q4 which eliminates the members based on the legacy Eta and RSM models and adds members based on the NEMS-NMMB. Membership will remain at 21 by having 7 members generated each by NMMB, WRF-ARW and WRF-NMM. This upgrade would also increase resolution from 32-25km to 22-25 km, add a BUFR output, and may transition to an ensemble perturbation approach. The WRF Development Testbed Center (DTC) is helping evaluate different initial perturbation possibilities. The Eta and RSM models will be discontinued, pending all dependencies on Eta and RSM models can be removed.

and also remember that Upton doesnt forecast just for NYC their CWA stretches into eastern CT to the RI border. Geographically speaking the NWS station is relatively close to the middle of the CWA

I think they have the toughest forecast area because occasionally their coastal zones do not act as coastal as you expect during winter events...coastal NJ is easy for Mt. Holly because no matter what a NNE, NE, E wind has an ocean component...same for Taunton, but for Upton sometimes that mix or changeover is delayed or does not happen at all...their coastal zones are much easier to keep trapped in the cold air.

Very true, much of the CT coast and norther LI coast is not exposed to the open ocean and as a result are usually the last of coastal areas to change over (if at all) during marginal events. Not to mention Upton has to watch out for over 21 million people.....do they have the most populous CWA in the country?

I've always argued that Fairfield County has respectable winters and the Bridgeport snowfall record is questionably low..

Having grown up in New Fairfield (far NW corner of the County) in the late 70's and 80's, I can attest to some very respectable winters and a sizable difference in snowfall even as compared to Danbury.
