Long Island weather forecast: Sunny skies but high risk of wildfires

The National Weather Service has extended Saturday's warning of an elevated risk of wildfires to Sunday.

Long Island, along with New York City and Westchester, Putnam, Orange and Rockland counties in the lower Hudson Valley, face the danger caused by low relative humidity and dry vegetation.

"Outdoor burning is strongly discouraged," the weather service said, adding that potential ignition sources, including cigarette butts, should be properly extinguished and disposed of.

Otherwise, Sunday looks to extend Long Island's run of mild fall weather. The weather service Saturday evening was predicting sunny skies on Sunday with a high temperature near 57 degrees, which would be 3 degrees cooler than the normal high for the date in Islip.

A north wind of 3 to 5 mph was expected.

Sunday night should be mostly clear, but the temperature could slide down to around 37 degrees, according to the forecasters. 

The weather service even said that on Monday before 8 a.m. there will be patchy frost. For the rest of the first day of the new workweek, more sunny skies are expected with a high temperature near 59 degrees.
