Update on the rain, tropics, potential northern New England snow, and the Long Island forecast:

While Long Island will still likely get 1 to 2 inches of rain, amounts will be lower in southern New England as high pressure to the north keeps the rain mostly suppressed to the south.


Invest 93L in the Atlantic now has a 30% chance of tropical development in the next day or two before strong upper level winds limit development.


We have to watch the southwestern Caribbean for potential tropical development between around October 21st and 24th. The GFS ensembles are more bullish than the Euro ensembles.


The Euro is showing a good amounts of snow for northern NH and VT this weekend from a storm system that forms along the front, but there is uncertainty still.


Long Island forecast:


Today: Periods of rain and breezy with gusts up to 30 mph with temperatures in the mid to upper 50's. The rain will become more scattered this afternoon and evening before more rain moves through overnight into tomorrow morning.

Tomorrow: Showers at times in the morning into early afternoon with partial clearing possible by late afternoon with highs in the upper 60's.

Wednesday: Mostly sunny with highs around 70 degrees.

Thursday: Mostly sunny with highs in the low 70's.

Friday: Partly to mostly cloudy with a 50% chance of showers by late afternoon or evening. Highs in the low 70's.

Saturday: A chance of morning showers and then clearing in the afternoon and cooler with highs mostly in the low 60's.
