Seasonable temperatures for Long Island are expected for Sunday and the start of the workweek with plenty of sun predicted and a high of 60 degrees for Tuesday’s election after a chilly morning, forecasters said.

“Sunday will be a little bit cooler than Saturday was . . . but it’s still a very nice day,” News 12 meteorologist Bruce Avery said. “The winds will start to pick up on Sunday,” he added, noting that gusts from the northwest at 10 to 20 mph are expected.

The same comfortable weather is predicted for the start of the TCS New York City Marathon in Staten Island on Sunday morning. Wheelchair racers are scheduled to kick off the event at 8:30 a.m. with additional staggered starts through 11 a.m.

Avery predicted a high of 55 in many areas of Long Island on Sunday. The low will be a chilly 36 with even cooler lows predicted for the pine barrens.

“It’ll be cool for the beginning of the week,” Avery said.

Tim Morrin, a meteorologist for the National Weather Service at Upton, said no rain is in the forecast for the week.

“For the most part the week is going to relatively dry — there isn’t precipitation through Saturday and we’ll be remarkably close to normal highs, which is 56 for [Sunday] at Islip.”

Monday, look for mostly sunny skies with highs near 53 degrees and lows around 37.

Avery predicted “a nice election day” Tuesday due to the warm high and dry conditions. Temperatures will continue to be relatively warm at night for last-minute voters with lows dipping into the mid-40s.

“The morning’s going to start out chilly in the very early morning and people may see some frost — temperatures will be in the mid-30s,” Morrin said. “The rest of the day will be sunny and relatively mild with temperatures reaching about 60 in the afternoon.”

Wednesday will be a mix of sun and clouds with highs near 58 degrees and lows near 44.

Thursday is forecast for a high of 59 degrees and lots of sun in most areas with a low of 46.

A mix of sun and clouds starts the weekend Friday when highs near 59 are again predicted, with lows near 40.
