We have a Heat Advisory in effect through 8 p.m. today, with heat index values approaching 100 degrees across much of Long Island. An Air Quality Alert is also in effect until 11 p.m. due to elevated ozone levels, which could make it difficult for sensitive groups to spend extended time outdoors. If you're heading outside today, be sure to stay hydrated, take frequent breaks, and limit strenuous activity during the hottest part of the afternoon.
Today's forecast calls for a mix of sunshine and clouds with hot and humid conditions. Afternoon temperatures will climb into the upper 80s and low 90s, and there's even the potential to set a new record high. The forecast high is 92 degrees, which would break the current record of 91 degrees set in 2017. During the late afternoon and evening, scattered showers and thunderstorms are expected to develop. A few storms could become strong, producing damaging wind gusts, torrential downpours, and even some small hail.
Tonight, any lingering showers or storms will gradually diminish, with overnight lows settling into the 60s to lower 70s.
The weekend is shaping up very nicely. Saturday brings plenty of sunshine with warm and somewhat humid conditions. High temperatures will reach the mid to upper 80s, with a few spots across western Nassau County touching the lower 90s. Saturday night will be partly cloudy and mild, with temperatures holding in the 60s and 70s, making for a comfortable evening if you have outdoor plans.
Sunday starts with sunshine before a few afternoon clouds develop. High temperatures will once again reach the 80s, and most of the daylight hours will remain dry. We'll watch for a few showers to develop Sunday night into Monday morning. Overall, it's an excellent beach and boating weekend, but don't forget the sunscreen—the UV index will be high, and with the hot weather and strong June sun, it won't take long to get burned. Have a safe and enjoyable weekend!
