Warm, humid with a slight chance of a stray shower or thunderstorm in the afternoon.

That’s Long Island’s weather picture for Monday, forecasters say, as the final days of July are on the horizon.

“Another July sizzler in store today across the entire area,” the National Weather Service’s Upton office said in a tweet.

An air quality alert is in place through 10 p.m. for Long Island, meaning elevated levels of ozone could result in health issues, especially for the very young, those with pre-existing respiratory problems and those engaged in strenuous outdoor physical activity.

Look for clouds to build, with a sea breeze off the ocean meaning slight chances of an afternoon pop-up shower or storm, said Rich Hoffman, News 12 Long Island meteorologist. For the most part, the day is dry, he said.

The approach of a weak disturbance also means a chance for showers and thunderstorms, but that’s mostly for areas north and west of New York City, the weather service said.

Hot and humid are the words of the day, with temps expected to rise to the upper 80s, even low 90s in some spots — much cooler, though at the beaches, Hoffman said.

As of just around 10 a.m, Long Island MacArthur Airport was reporting fair skies and a temperature of 85 degrees, feeling more like 91, given the humidity. Normal air temps for the day are 82 for the high, and 67, the low.  

At that time Jones Beach was at 77 degrees, Hempstead and Montauk at 82.

And, look for more heat and humidity Tuesday, Hoffman said.

As for best chances of showers and storms, the time to watch is later Wednesday and overnight into Thursday, Hoffman said.

After that, the forecast is for sunshine and highs in the mid-80s for the first days of August and right through the weekend.
