Euro has close-call snowstorm for Long Island with a little ensemble support:

First, we have the system with snow showers moving across the northeast. It won't get to Long Island until early afternoon, so it could be light rain or snow showers. Then we have the sunny and milder weather tomorrow and Friday before more clouds and possible showers at times from Saturday late afternoon into Sunday afternoon possibly.

While most of the models have the next storm for early next week stay south of Long Island and slide offshore, the Euro has Long Island on the northern edge with the potential for rain changing to snow late Monday night and continuing into Tuesday afternoon with the potential for 6 inches of snow. That would still have to be considered a long shot at this point. However, it does have some ensemble members showing it as 9 of the 50 ensemble members are showing 2 inches or more of snow for Long Island early next week. Also, the GFS, which usually has an offshore bias, has been trending westward with the storm.


Today (Wednesday): Cloudy with a 40% chance of light rain or wet snow showers in the early to mid-afternoon with highs around 38 to 40 degrees with wind gusts up to 20 mph from the WSW in the afternoon. The best chance for it being snow showers is northwest Nassau.

Tomorrow (Thursday): Mostly sunny and milder with highs in the upper 40's.

Friday: Partly cloudy with highs around 50 degrees.

Saturday: Cloudy and mild with a 30% chance of showers by mid to late afternoon, especially in Suffolk. Highs in the low to mid 50's.

Sunday: Mild with a 50% chance of showers, mostly in the morning into early afternoon. Highs in the mid 50's.

Monday: Partly to mostly cloudy at times. Highs in the mid 40's. There is a slight chance of rain changing to snow overnight.
