Long Islanders can look forward to seasonable spring temperatures this week, but much-needed rain is also expected on and off throughout the week starting Monday, according to meteorologists.

“It’ll be a gorgeous day today (Sunday) from sunrise to sunset and there’ll be mostly sunny skies,” said Matt Hammer, a meteorologist for News 12 Long Island. “And it’s not looking too bad for the next seven days.”

On Sunday the high will be 60 degrees in most areas, with Islip predicted to reach 61, according to Carlie Buccola, a meteorologist for the National Weather Service at Upton. The low at night will be 44.

“I think spring is finally here,” Buccola said. “The average high is 61, and it’ll be around seasonable for the rest of the week.”

Dry, gusty conditions in the region last week prompted the weather service to repeatedly issue red-flag warnings that any wildfires that start could easily spread.

And again, early Sunday morning, the service put out a hazardous weather alert that an air mass has moved in that makes for an “elevated state” of dryness and potential fire danger.

Lots of sun is predicted for the return to work on Monday when there will be an even warmer high of 66 — but a 50 percent chance of showers is forecast for throughout the day, and the low will drop to 52.

Clouds come in on Tuesday, bringing with them a 70 percent chance of showers and a high of 60. Those clouds will hang around throughout the night when the low will be 44. Showers are expected to arrive before 9 p.m.

Sun returns on Wednesday when it will be mostly sunny but slightly cooler with a high of 57 and a low of 45.

Some rain may return on Thursday when there’s a 30 percent chance of precipitation after noon and the high will start climbing again and reach 59. The low will be 48.
