Long Island Sees Rain Later Today Tonight Warmer More Humid Conditions Moving In
The frontal boundary offshore remains stalled out and we are seeing the next wave of low pressure developing in Eastern North Carolina. The first wave yesterday was weak and only produced clouds. This one has more moisture and a little more punch to it. The low will also track offshore but it will bring an area of rain northward and Long Island will be seeing some of this rain later today into tonight.
Brighter white clouds tops show up over Eastern North Carolina and that is being reflected on the radars as a solid area of heavy there. That little core of rain will be moving north and that brings some brief heavy rain late this afternoon and evening for Long Island. The heaviest rain will be east in Suffolk County particularly Eastern Long Island while the rain sharply cuts off in Western Nassau County and NYC.
As far as rainfall is concerned, the range across Long Island will be wide. In Western Nassau County for example rainfall amounts will be under a quarter of an inch and possibly only a tenth of an inch which is enough to make a few small puddles. Over Eastern Long Island we are looking at 1 to 2 inches of rain with the area in between splitting the difference.
We are really talking about 3 to 6 hours worth of rain at most and it should all be gone tonight. There will be clouds around overnight and clouds continue on Thursday with the stalled front offshore. There will be one more wave to move northeast on the stalled front but the next wave passes east and is offshore so no additional rain is forecast for Thursday. Highs Thursday will be in the 70s.
Friday begins the transition into a very warm and much more humid pattern. Clouds will give way to some sunshine on Friday with highs in the upper 70s to lower 80s. Saturday and Sunday will be very warm and humid with highs in the mid to upper 80s away from the ocean. There should be some sun both days. The GFS is bringing an upper air system northeastward from the Gulf States with a little wave. This sets off some showers and thunderstorms Saturday night and then gone by Sunday morning. I’m not quite sure what to make of this but for now will lean optimistic for the dayside of Saturday and Sunday as the rain threat times out for Saturday night.
