Quick update on the Christmas rain/wind storm and the Long Island forecast:
Overall, there haven't been many changes with the overall pattern with the cold front bring heavy rain and strong wind gusts to Long Island and New England, but there are some slight differences with timing. Also, it appears that any accumulating snow would be well inland towards western PA and western NY state. The general timing for the heaviest rain and strongest wind looks to be late Christmas Eve night or on Christmas morning. The potential is still there for gusts well over 50 mph from the SSE. See the images below and the Long Island forecast for more details.
