Timing the Rain on Long Island This Weekend
The Euro (1st image) is showing rain for Saturday night into early Sunday morning. The GFS (2nd image) keeps the rain south of Long Island, so we get nothing at all. The UKMET has just light rain Sunday morning, with most of the rain south of Long Island. The NAM has rain for late Saturday night into Sunday late afternoon.
As you can see, the models haven't converged yet. Best chance for rain seems to be Saturday night into Sunday morning.
