Update on Tornado, Hail, and Damaging Wind Threat for Long Island Later Today

It will become humid this morning as the warm front move from southwest to northeast through Long Island, and there will be a chance of a few showers this morning. It will then become partly to mostly sunny and very warm this afternoon with highs near 90 degrees for most of Nassau, upper 80's for western Suffolk, and low 80's for eastern Suffolk. There is some uncertainty in the timing of the severe thunderstorms, but the best chance is from around 6 PM to 9 PM. It's important to note that they will be moving from north to south. Also, some of the models are showing the better chance might be in Suffolk. There is the potential for significant wind (75 mph or greater) and hail (2 inch diameter or larger), as well as an isolated tornado. From the National Weather Service: "Initial storm mode is expected to be discrete/supercellular, with the potential for damaging winds, large hail, and an isolated tornado. As the storms sink south, they are expected to evolve into several clusters or a line, with damaging winds being the primary threat."


For Long Island, tomorrow will be partly cloudy and fairly humid with highs mostly in the mid to upper 80's with only a slight chance of an isolated thunderstorm in the afternoon/evening. Saturday will be very humid and tropical with periods of showers and thunderstorms becoming more likely later in the day and at night. There will be very heavy downpours at times. Sunday through Tuesday will then be mostly sunny with low humidity with highs generally in the mid to upper 70's.


Tropics:

- Hurricane Laura made landfall as a strong Cat 4 with 150 mph sustained winds earlier this morning at Cameron, Louisiana.

- There will be plenty of more action in September, but we get a little break for now.
