- The details for Long Island are in the forecast below, but we have the rain and windy for tomorrow afternoon and especially evening with strong wind gusts and moderate to heavy rain as temperatures could reach 60 degrees in the evening before falling late in the evening.
- The next frontal system for Wednesday afternoon/night looks to bring even more wind with rain, and I wouldn't be surprised to see wind gusts of 40 to 50 mph on Long Island. See the 4th image showing an ensemble mean max gusts of 49 mph (43 knots). Once again, temperatures could reach 60 degrees before the front passes.
- Temperatures then return to more seasonable levels and then possibly below normal at times.
- The Euro ensembles are starting to increasingly look snowier once we get into December and towards around December 10th. Best chances are of course in the higher elevations or northern New England/NY, but some ensembles are even showing snow for Long Island and southern New England, but of course, the chances are fairly low (see images below).
