Long Islanders will be treated to unseasonably mild conditions this week as a high-pressure system will bring in warmer temperatures that could reach the mid-70s, according to the National Weather Service.

After a Sunday that is expected to see high temperatures climb to 71 degrees across inland parts of Long Island, the high is forecast to reach as much 75 degrees Monday, said meteorologist Matt Wunsch of the National Weather Service in Upton.

"It should get progressively warmer, pretty much through Tuesday," Wunsch said. "Then you will have a subtle cool down on Wednesday and then, toward the end of the week, back to seasonal temperatures."

Monday’s forecast high is more than 10 degrees above the average temperature of 63 degrees, according to information compiled at the National Weather Service’s climate center in Islip.

The high temperature Tuesday is expected to reach the low 70s along the coast and as much as 74 degrees inland, Wunsch said. The Wednesday high will be about 71 degrees inland with coastal areas reaching the upper 60s, he added.

Low temperatures through Wednesday should remain in the low-to-mid 50s, also higher than the average low of 46 degrees for this time of year, according to the weather service.

Wunsch said that with the high-pressure system overhead, skies will remain clear through midweek with virtually no risk of precipitation in the forecast. A frontal system passing by could bring some cloud cover overnight Wednesday into Thursday, with the high temperature only expected to reach 65 degrees the following afternoon, he said.

"It will stay down around the 60s into Friday and Saturday," Wunsch said.
