Long Islanders can look forward to a return to cooler temperatures starting on Sunday, but forecasters also say to expect some rainy conditions starting late Saturday night.

As for Friday, the temperature reached 92 degrees at Long Island MacArthur Airport, and at some points during the day felt like 94, thanks to the humidity, the National Weather Service said.

Saturday sees sunny skies with highs in the upper 80s to around 90 degrees, along with continuing humidity, said Faye Barthold, weather service meteorologist in Upton.

The overnight hours into Sunday then bring a 50 percent chance for showers and thunderstorms, with the potential for some to bring heavy rain and gusty winds, the weather service said.

Precise timing and intensity have yet to be determined this far in advance, Barthold said.

As of late Friday afternoon, those chances drop to 40 percent during the day Sunday, which sees high temperatures of around 80 degrees.

Chances of rain continue through Sunday night, Monday and Monday night, the weather service said. Highs Monday are in the low 80s.
