Showers may still be in the forecast for Friday, but at least temperatures are cooler — by more than 20 degrees.

Long Island MacArthur Airport saw a high of 92 on Thursday, tying the record for the day. Just before noon Friday, the airport in Ronkonkoma recorded a temperature of just 68 degrees.

Friday is looking at highs in the low 70s, the National Weather Service said. Normal for the day is 82 degrees.

After Friday morning’s rain, there was expected to be a lull in afternoon precipitation, the service said, though showers are still possible along with a slight chance of thunder.

Another round of showers and thunderstorms are possible late evening into overnight.

“We’ll see cloudy skies with on and off showers today,” said News 12 Long Island meteorologist Matt Hammer. “Any shower may produce a downpour.”

There is also a “low chance for localized flash flooding” in Nassau and Suffolk from late Friday afternoon into evening, the service said in a hazardous weather outlook.

Weather conditions on Friday were causing flight disruptions at LaGuardia and Kennedy airports, according to the Federal Aviation Administration website. Travelers are urged to check with their airlines for the status of specific flights.

On Saturday morning, “we’ll see an early leftover shower,” Hammer said, “then developing sunshine with highs back in the 80s.”

“Mainly dry conditions are expected for the weekend with seasonable temperatures,” the weather service said in its regional summary.

Saturday, which sees decreasing clouds, gradually becomes mostly sunny, the weather service says.

With Saturday and Sunday expected to see temperatures top out in the low to mid-80s, sunny skies are forecast for Sunday.
