Long Island weather: Bright skies, cool temps for start of holiday week

More crisp autumn weather is on the way: Columbus Day will bring sun-splashed skies and cool temperatures, with a warmup later in the week, forecasters said Sunday.

Sunday's bright clear skies with a 63 degree high will give way to a chilly night, with a low of 48 degrees, according to the National Weather Service. The first part of the week will feature "tranquil" conditions, the weather service said, with the next chance for rain Thursday.

Until then, mostly clear skies will continue Monday — Columbus Day — with a high near 64, forecasters said. The skies will remain mostly clear in the evening with the thermometer dropping to about 49, the weather service said.

Temperatures will warm up Tuesday to 68, with plenty of sunshine throughout the day. Tuesday night will remain clear, with a low of 51.

Warmer temperatures and sunny skies will continue into Wednesday, with a high of 68, the weather service said. At night, the temperatures will drop down to about 57.

The next chance for precipitation comes Thursday afternoon, when showers are expected after 2 p.m. The high will be near 70.

"A frontal system approaches on Thursday, with a possible wave of low pressure developing along the front as it passes through the region Thursday night into early Friday," the weather service said Sunday.
