With the unofficial end of summer this weekend, it seems fitting that a warm, humid pattern settles in after it. This week, Long Island will see above normal temperatures and higher humidity as September begins.
The weekend started off with a beautiful getaway day with lots of sun and highs in the 70s. Saturday saw the 70s as well, but clouds took over by the afternoon. Those clouds really stick around for the rest of the holiday weekend, and a chance of showers and thunderstorms is added.
Sunday will feature mostly cloudy skies and higher humidity levels, in the uncomfortable range. Highs will reach the upper 70s along the immediate south coast and East End to the upper 80s on the North Shore. The highest readings are achieved especially with any breaks of sun. As a frontal boundary approaches, there is the chance for showers and thunderstorms after 3 P.M. This rain chance continues into the muggy night.
Labor Day Monday features more showers and thunderstorms, but not a washout like the rest of the weekend. There's a slightly higher chance in the morning for thunderstorms (pop-up or leftover) but the humidity will be quite high all day. Highs on Monday are in the 80s.
Monday's frontal boundary leaves and dissipates, and is followed by another on Tuesday. This brings more showers and thunderstorms to the area, and keeps the warm temperatures (highs in the 80s) and high humidity around. The forecast dries out for the rest of the week with highs in the 80s and still, a lingering feel of summer.
