GFS finally comes around and now shows the Sunday coastal storm as well:
- The Long Island forecast is below, but tomorrow will be a beautiful day, and then the cold front comes through Wednesday afternoon/evening with showers and possibly a thunderstorm (2nd image is for 6 PM Wednesday) as it will become windy Wednesday night. Chilly on Thursday with gusts up to 40 mph possible.
- The Euro, GFS, and Canadian now all show a coastal storm for Sunday (see 4th to 6th images). The exact timing, track, and intensity are still uncertain, but as of now, I would say 1 to 2 inches of rain are possible on Long Island between around midnight Saturday night and 6 PM on Sunday with wind gusts up to 40 mph, possibly higher right along the shore.
