Uncertainty with the potential coastal storm for Tuesday afternoon into Wednesday morning:

- Some patchy early morning fog this morning, and it will be a mild day with a few light showers at times with the best chance being from around late morning to mid-afternoon for Long Island. The cold front moves through tonight with some showers, mainly before 2 AM. It will be very mild in the evening with temperatures dropping towards morning to the low to mid 40's.

- The cold front will be stalled to our south on Friday, and there is still a slight chance that it is close enough to us Friday morning for some showers with the best chance (but still a low chance) for the south shore. I have included a future radar video below.

- Saturday is basically a washout, especially in the afternoon and evening, and there is a slight chance of thunder Saturday evening. Total rainfall from this morning through Saturday night is expected to be less than 1 inch on Long Island.

- The models and ensembles are still kind of all over the place with the developing coastal storm for Tues/Wed. I have included some maps from the Euro ensembles below. The new ensembles aren't quite as bullish as the run from yesterday afternoon, but there are still a handful of them that bring snow even for Long Island. It's possible that the storm strengthens when it's a little too far offshore or even too far south. Stay tuned for updates!
