- While there is still a good deal of variation in the snow amounts from the models, they continue to show the colder air being tough to remove initially and an ENE-pivoting low-pressure system once it gets near the NJ coast. - The amounts from the overnight Euro run are slightly higher than the amounts from the evening run that I posted last night on the Facebook page. I will post some of the snow maps below, but remember that I can't post the Euro map due to licensing restrictions. - My general thinking is that snow develops between 3 PM and 5 PM on Thursday for Long Island. While the Euro is showing 4 to 6 inches, I think 2 to 3 inches is more realistic for Nassau and 1 to 2 inches for Suffolk, with less for eastern Suffolk. It will definitely change to rain tomorrow night. - 1st image: 24-hour snowfall from the GFS from 1 PM Thursday to 1 PM Friday. It loses resolution over Long Island, but it gives you the general idea. - 2nd image: 24-hour snowfall from the Canadian model from 7 AM Thursday until 7 AM Friday. - I won't post the FV3-GFS snow map as it's showing even higher amounts which I believe are unrealistic. - The Euro ensemble mean shows 4 inches for NYC, 3 inches for western Long Island, 2 inches for central and eastern Long Island, 3 to 4 inches for CT, 1 to 2 inches for Boston, and 4 to 5 inches for NW NJ towards Philly.
