THIS EVENING AND OVERNIGHT
After a nice and warm day with highs in the upper 70s to lower 80s across much of Long Island, this evening continues to be amazing for any outdoor activities. Temperatures will gradually cool down through the 60s by mid-evening under a mostly clear sky. It will stay clear and comfortable overnight, too, with low temperatures in the 50s to low 60s into early Thursday morning.
WARMING TREND CONTINUES
The humidity will stay fairly low through Friday and high temperatures will keep rising into the start of the weekend! Highs tomorrow will be in the lower to middle 80s away from the immediate South Shore and East End under a mostly sunny sky.
Expect more of a mix of sun and clouds around at times Friday and Saturday, but both of those days will be the hottest days this week with afternoon temperatures in the upper 80s to lower 90s. The humidity will be tolerable, but a bit more noticeable by Saturday.
This entire stretch will feature good outdoor weather, but be sure to use sunscreen with the UV index remaining very high through Saturday.
50-50 WEEKEND ON THE WAY
If you are making outdoor plans for the upcoming weekend, Saturday is easily the better outdoor day. Keep in mind that it will feel hot with noticeable levels of humidity. It is expected to be a good beach and boating day, too and you will definitely feel slightly cooler air at the South Shore beaches.
Sunday should not be a total washout, but it will not be as hot - although warm and humid - with highs around 79 degrees. Scattered showers and even a possible thunderstorm will be around through the day. Otherwise, partly sunny to mostly cloudy.
