After sunny weather for Long Island through this weekend, stormy weather will return later this month. It looks like the potential for a heavy rain event next Tuesday and Tuesday night, and then the GFS is showing a hurricane affecting southern Florida and then rapidly advancing northward and passing just east of Long Island on the 29th/30th. Of course, it's much too soon to tell the exact path or strength, or if it will even develop.
The following image from the GFS shows potential Hurricane Philippe off the coast of North Carolina at 8 PM on October 29th:
