Active weather with warmth, thunder, heavy rain, strong winds, wet snow, and cold fronts:

There is a lot going on! The detailed forecast for Long Island is below, but here's an overview: - Very mild ahead of the cold front today with highs in the 70's for NYC and NJ with a wide temperature range for Long Island from the mid to upper 60's in northwestern Nassau to the low 50's out by Montauk. Strong cold front with strong wind gusts over 40 mph and a period of moderate to heavy rain with thunderstorms mostly west and southwest of Long Island with a damaging wind threat there.

- The next system is for Wednesday with some accumulating snow for parts of the Mid-Atlantic and some rain with some wet snow at times for Long Island and southern New England, but we will be on the northern fringe. I will be updating more on this today and tonight, but the NAM and some of the Euro ensembles are showing some light accumulations even for Long Island. The NWS is going with a chance for a very light coating (4th image). in the morning at the beginning and in the evening at the end.

- Then the strong cold front for Saturday with rain and strong wind gusts with the heavy snow well to the northwest in NY state and New England. Then cold and windy for Sunday behind the storm.
