Could there be a snowstorm on the horizon? Also, the detailed Long Island forecast:

  • We all know about the rain and wind storm that is coming for Christmas Eve at night into Christmas morning with the potential for damaging wind gusts up to 60 mph on Long Island, and more details for the tri-state area are shown in the 1st image and also my Long Island forecast below.

  • It will be followed by a sunny, but cold weekend.

  • Then there will be some rain around next Tuesday for Long Island with possibly some snow farther north. I will be posting more about this. The Canadian had a strange solution with a huge snowstorm for western Long Island and rain for Suffolk. The Euro ensembles, however, show only a very slight chance of snow for Long Island on Tuesday.

  • Looking ahead though, could it set the stage for a snowstorm New Year's Eve into New Year's Day? That's what the new Euro run is showing, but it's 10 days out, so don't read too much into it yet. Also, only a few of the Euro ensembles show it, but it will be interesting to watch the trends.


*There is the potential for a Wind Advisory or High Wind Watch to be issued for the overnight period from Christmas Eve into early Christmas morning as wind gusts could reach 60 mph for parts of Long Island* Today (Tuesday): A chance of light early morning showers and then becoming partly to mostly sunny in the afternoon with highs in the low 40's. Breezy in the afternoon with wind gusts of 20 to 25 mph from the WNW. Tonight: Mostly clear and still a little breezy with lows mostly in the upper 20's. Tomorrow (Wednesday): Mostly sunny with highs in the low 40's with light winds. Thursday (Christmas Eve): Cloudy and mild with a slight chance of a shower in the afternoon, but with a better chance of a steady rain developing at night after 11 PM as a strong cold front approaches. Highs will be in the mid to upper 50's with a S to SSE wind up to 25 mph. Overnight, the rain will be heavy at times with strong wind gusts of 45 to potentially 60 mph into early morning on Christmas with temperatures approaching 60 degrees before the cold front moves through. Total rainfall should be close to 1.5 inches. As of now, the heaviest rain looks to be between 2 AM and 6 AM. Friday (Christmas Day): Early morning rain and wind ending possibly around mid to late morning from west to east with temperatures dropping throughout the day from the upper 40's to low 50's early in the morning into the mid 30's by late afternoon as the wind shifts to the W behind the front with gusts of 20 mph in the afternoon. The sun should come out in the afternoon. Saturday: Mostly sunny and very cold with highs in the low 30's. It will also be breezy. Sunday: Mostly sunny and cold with highs in the mid 30's.
