A gradual cool-down in temperatures is expected this week on Long Island, with the season's first frost arriving along with lows in the 30s some nights.

November's early daytime highs will start to slide from about 60 degrees in some places Monday down to the low 50s by Saturday. Lows will begin to break through to the 30s Tuesday, Thursday and the weekend.

Tuesday will be cloudy with light winds and a low in the high 30s

Wednesday, although it will be sunny, will turn cold. Lows drop to the mid 30s overnight Wednesday, setting the stage for the season's first patchy frost to appear, although the pine barrens may see some earlier in the week, forecasters said.

"This will bring likelihood for first widespread frost Wednesday night, and potential for localized freeze," the National Weather Service said.

The retreating temperatures arise in part from a sky-clearing Canadian high pressure system heading to the tristate area by Monday night, the weather service said.

Meanwhile, Wanda, a subtropical storm whose name has now exhausted the named storms of the hurricane season, is expected to turn northeast this week but pose no danger to land, the National Hurricane Center said.

Wanda is the 21st named storm of the season and may develop into a tropical storm over the Atlantic as it moves slowly northeastward but it will be too far out to sea to have an impact on Long Island.
