Severe thunderstorms swept across Long Island Saturday, but temperatures across the area are expected to cool Sunday with some showers, according to the National Weather Service.

"The morning will be wet on Sunday, but then pretty much tapering off and drying out through Sunday," National Weather Service meteorologist James Tomasini said. "The further east you are, the higher the chances are ... Nassau County is expected to be dry by mid-afternoon. For Suffolk County, it might be closer to 6 p.m."

Sunday is expected to be chilly with high temperatures below 70 degrees. Conditions will warm slightly on Monday, bringing dry weather with temperatures just above 70, according to Tomasini.

The National Weather Service forecast doesn’t call for rain again until Wednesday.

Nassau County was under a severe thunderstorm watch for a large part of  Saturday, the weather service said. 

Saturday morning was dry and mostly sunny with a high temperature around 80 degrees. Thunderstorms hit New York City around 2 p.m., then spread east over most of Long Island, Tomasini said.

The meteorologist said that there was a possibility that the storm could bring tornadoes and hailstorms "north and west of New York City."

The severe thunderstorms were likely to be "isolated" or "scattered" throughout Long Island, he said.

Authorities in Nassau and Suffolk counties said that no damage had been reported as of 6 p.m.
