Parts of Long Island are looking at not only a warm spell, but possible heat-wave warmth, forecasters say.

Saturday is heading up to the lower 80s at Long Island MacArthur Airport, according to the National Weather Service in Upton.

But, as of Friday afternoon’s forecast, Sunday, Monday and Tuesday could reach the upper-80s, a stone’s throw from 90 degrees, with three consecutive days of 90 or above considered a heat wave.

With this “hot weather on the way,” western Nassau County has the best chance for hitting at least 90 three days in a row, said Rich Hoffman, News 12 Long Island meteorologist.

The weather service’s website is also showing around 90 degrees as possible highs for the North Shore areas of Nassau and western Suffolk for Sunday through Tuesday. Eastern Suffolk and some areas along the South Shore could see low to mid 80s, said Faye Barthold, weather service meteorologist in Upton.

Oh, and this is all with sunny or mostly sunny skies!

“A notable warming trend will take place this weekend as hot air from the Plains spills eastward across the United States,” the weather service said in its regional summary.

What’s more, records could be tied or broken.

Record highs for Monday and Tuesday at the airport are both 88 degrees, with 88 also the forecast for those days, said Jim Connolly, another weather service meteorologist in Upton.

As for any accompanying humidity that could introduce discomfort, there was no indication as of Friday for that being much of an issue, Barthold said.

Of course, temperature calls could always shift somewhat in future updates, Barthold said.

Backing up to Friday, though, and there’s a high risk of rip currents for the entire South Shore from 8 a.m. through 9 p.m., the weather service said. Swimmers caught in a rip current should not swim directly for shore, but are advised instead to swim parallel to the shore to get away from the swift-moving waters.

Saturday looks like a repeat of Friday, with mostly sunny skies and temperatures in the low 80s, but also with a chance of isolated showers and thunderstorms in the early afternoon, the weather service said.
