We’re starting the day with cloudy skies and a few rain showers around Long Island, but the wet weather should begin to dissipate after 9 a.m. From there, expect a mixture of sun and clouds developing through the afternoon. It’ll be warm and a bit more humid, and for some it may even feel hot. High temperatures will reach the mid-80s away from the water, with 70s along the immediate shoreline. Feels-like temperatures could approach 90 degrees in some spots. There’s a slight chance of a passing afternoon shower, but most of the day should remain dry.
