Brief 3:45 AM post on the nor'easter with rain/snow maps and the Long Island forecast:
You can see the Long Island outlook in the 1st image. I have included snow maps from the Euro and NWS Model Blend in the 2nd and 3rd images. The 4th and 5th images show the maps from the Euro at 2 AM and 8 AM on Tuesday. The projected precipitation through 8 PM Tuesday is shown in the 6th image, and then you can see Long Island temperatures in the last image.
