Timeline Of Stormy Weather For 1st Weekend Of Summer

A stormy start to the first weekend of summer is likely across Long Island, according to forecasters.

Saturday is likely to be the wettest of the two weekend days, with showers and isolated thunderstorms expected in the morning.

"The activity will likely dissipate in coverage late morning and into the afternoon with the potential for a long break," the National Weather Service says. "However, the associated upper trough will move across the area in conjunction with the warm front toward the late afternoon/early evening. This combined with increasing elevated instability will result in another period of widespread showers and scattered thunderstorms."

While there is a chance for showers and thunderstorms on Sunday, it's unlikely to be a washout if you have outdoor plans.
