New snowstorm update from 06Z Euro ensembles and new maps from TWC:
The 06Z Euro run only goes out 90 hours, but at the end of the run, the snow wasn't close to Long Island yet. So, as of now, it looks like the snow would start sometime between 11 PM Sunday and 4 AM Monday on Long Island.
The 06Z Euro ensembles do go out 6 days, and they shifted the snow slightly to the southeast with perhaps less overall snow though.
The new maps from The Weather Channel are also posted below, and you can see the mixing possible on the southeastern part of Long Island.
Here is the new Hazardous Weather Outlook from the NWS for Long Island and the entire Tri-State area: "There is the potential for a coastal storm to bring 6 or more inches of snow to the area late Sunday night into Tuesday. Additionally, strong northeast winds, coastal flooding, and beach erosion will be possible. At this time, there remains a fair amount of uncertainty with the low track and timing to be specific with details."
