New temperature record in Islip

A record temperature was reached in Islip on Wednesday, breaking a mark set 25 years ago, according to the National Weather Service.

But cooler temperatures are on the way.

Wednesday’s temperature reached 65 degrees, breaking the previous record set in 1998 by one degree, according to Dominic Ramunni, meteorologist at the National Weather Service in Upton. Wednesday also hit the previous record temperature of 66 for Central Park, a mark last seen in 1950, he said.

“We were in a pattern with all this mild air coming in from the south and east,” Ramunni said. “The jet stream was further north than we are used to at this time of year. It was quite an unusual track.”

However, a cold front should land Wednesday night into Thursday, ushering in a cooler air mass, weather forecasters said.

“Then we’re seeing slightly cooler temperatures again, but it looks like we’re going to be above normal all weekend,” said James Tomasini, another weather service meteorologist.

There is a chance of rain from outside Thursday night through Friday, with the chance of rain increasing on Friday, according to the weather service. The high will be around Friday 47, the weather service said.

Cooler air is expected to move in over the weekend and into next week. Daily highs are around 43 on Saturday, Sunday and through Tuesday, despite the sunshine, and overnight lows are just below freezing.

A wintry mix could emerge for the region early next week, according to the weather service.

“Look for a weak system to get Sunday night into the first half of Monday. Temperatures for frozen precipitation will be marginal on the coast…mainly snow inland and at least snow to a wintry mix and rain for the city and coast. There is currently no evidence that this system can absorb sufficient moisture from the Gulf and intensify before leaving the coast and entering the Gulf Stream. Therefore, any precipitation seems to be rather light,” said the weather service in its forecast discussion on Wednesday evening.
