Quick 3:45 update on the Christmas rain/wind:

The models continue to show the potentially strong wind gusts for late on Christmas Eve at night or on Christmas morning, although there are timing differences as the Euro is slow. We can refine the timing as we get a little closer, but temperatures will likely reach 60 degrees on Long Island and in southern New England with heavy rain and wind gusts from the SSE to SE at possibly 45 to 60 mph with temperatures dropping sharply behind the cold front.


I will have more updates this afternoon and evening.


LONG ISLAND FORECAST:


Today (Sunday): Cloudy with a 50% chance of showers in the afternoon, but Nassau and northwest Suffolk could get snow showers with highs ranging from the upper 30's in northern Nassau to the low 40's in Suffolk to possibly 45 at Montauk.

Tomorrow (Monday): Mostly cloudy with highs in the low 40's. Some light rain or wet snow showers are possible overnight.

Tuesday: A slight chance of very early morning rain or wet snow showers and then becoming partly to mostly sunny with highs in the low 40's.

Wednesday: Mostly sunny with highs in the low 40's.

Thursday (Christmas Eve): Cloudy and mild with a chance of some showers in the afternoon, but with a better chance of a steady rain developing sometime in the evening or overnight, depending on the timing, as a strong cold front approaches. Highs will be in the low to mid 50's with a SSW wind up to 25 mph. There is the potential for heavy rain and strong wind gusts over 50 mph overnight with temperatures reaching 60 degrees before the cold front moves through.

Friday (Christmas Day): Morning rain with wind gusts up to 40 mph with lingering showers possible in the afternoon with temperatures dropping throughout the day from the low to mid 40's in the morning into the upper 30's by late afternoon as the wind shifts to the W behind the front. It's possible it ends as wet snow showers.

Saturday: Mostly sunny and very cold with highs in the low 30's. It will also be breezy.
