Monday is a sign of things to come for Long Island, the National Weather Service said.

At least for much of this week.

Most of Nassau and Suffolk counties can expect warmer-than-normal temperatures through Friday with sunny to partly sunny skies and light winds, the service's Upton office said.

On the first workday morning with the clocks turned back, commuters Monday rolled out to clear skies that gave way to partly sunny conditions and daily highs in the low to mid-60s.

Light winds from the west blow from 3 to 6 mph.

News 12 Long Island meteorologist Bruce Avery said Monday "will feature mainly sunny skies and mild temperatures."

Avery said sunset Monday is 4:48 p.m., so many Long Islanders should be prepared to drive home in darkness.

Overnight lows in the upper 40s give way to cool clear morning conditions.

On Election Day, Tuesday, Avery said temperatures will be even warmer, with daily highs near 66 degrees.

"More sun and mild temps for Wednesday with a high of 68," Avery said.

Clouds enter the picture Thursday and Fridays with a slight chance of rain sprinkles.
