Scattered showers will continue for Long Island into Wednesday, before dry weather returns for Thursday.
The warm front that brought showers on Tuesday evening has moved to the north, taking the showers with it. Skies will be mainly cloudy throughout the morning, and the National Weather Service has issued a dense fog advisory that's in effect through noon. But, a weakening cold front will sweep through the region later in the day and will bring a chance of showers and even some thunderstorms through Wednesday evening.
High temperatures will be cool, in the upper-50s to near 60 degrees, with a 10 mph east wind shifting to the south later in the day
Any precipitation will end Wednesday night, and skies will clear. Sunshine will return for Thursday, although it will be breezy.
Easter weekend looks to be a bit wet as of now. Be sure to check back to LI Now in the coming days for my blog posts, to stay up to date on all Long Island weather.

Fun fact: The lowest 100 kilometers of the atmosphere is divided into four parts: The troposphere, stratosphere, mesosphere and thermosphere (from the ground up). The troposphere extends to about 15 kilometers above the earth's surface (depending on latitude), the stratosphere to about 50 kilometers, the mesosphere to about 80 kilometers, and the thermosphere above that.
