Get ready for a string of nice spring days on Long Island, starting with Saturday -- partly cloudy, with highs in the low 60s, forecasters say.

Outside of a small chance of an isolated afternoon shower on Saturday, there's no rain in the forecast through Monday.

From Sunday into next week, temperatures are expected to hit the low to mid 70s, with sunny or mostly sunny skies, according to the National Weather Service.

Thanks to an onshore flow in the coming days, much of the South Shore is likely to register about 5 degrees cooler than areas further north, say, near the Long Island Expressway, said John Cristantello, weather service meteorologist based in Upton.

Sunday is offering up "great weather" for the Long Island Marathon, said News 12 Long Island meteorologist Rich Hoffman.

Temperatures at 8 a.m. Sunday, near the race's starting time, will be close to 50 degrees, he said, and are likely to warm to 70 under sunny skies by 2 p.m.
