In between the nice day today and a great stretch of weather expected Sunday into the middle of next week, it appears that Long Island will be directly affected by a strengthening coastal storm (nor'easter) Friday evening into Saturday morning. The models vary a little bit regarding the exact positioning of the storm, but it appears likely that some stormy conditions will be experienced on Long Island with anywhere from 1 to 3 inches of rain (the NAM model is even showing 3 to 6 inch rainfall totals) and wind gusts as high as 35 to 40 mph along the immediate coast.
The latest run of the NAM model just came out, and it's showing the storm deepening to a 994 mb low just south of Long Island. It would bring rain from Friday late afternoon until mid to late morning Saturday. The following images from the NAM model show moderate to heavy rain covering all of Long Island at 5 AM on Saturday (image 1) and total rainfall of 3 to 6 inches for Long Island (image 2):
