It's going to remain hot through the weekend into Monday. And if you're heading to beaches on the South Shore, be mindful of rip currents this weekend, National Weather Service meteorologist Dave Radell said Friday night.

Heat indexes — a combination of heat and humidity that makes it feel warmer than the actual temperature — will be a little cooler Saturday than Friday, which saw temperatures in the high 80s. 

Still, Radell said Saturday's temperatures will be in the upper 80s and possibly close to 90 for most of the Island, warmer closer to New York City. Then the heat becomes a little more pronounced on Sunday, with temperatures reaching in the mid-90s, even to 96.

“We do have a moderate risk of rip currents at the Atlantic-facing beaches both [Saturday] and Sunday, so that’s one thing to be aware of for those heading to South Shore beaches this weekend,” Radell said.

It looks like the heat won't let up at the start of the workweek.

"The trend continues into Monday, a couple of degrees more, looks like the upper 90s to maybe 100, that's more toward Nassau and the city," Radell said. "Nonetheless it will be another day of hot and humid conditions." 

Expect a chance of thunderstorms through the weekend. 

"Scattered pop-up thunderstorms, and any of these storms can produce heavy rain and lightning," Radell said.

There could be a reprieve from the heat Tuesday, possibly with storms in the afternoon, Radell said. Highs are forecast in the mid-80s that day.  

The high on Friday in Islip reached 88, and for Central Park the high was 89.
