Tuesday gets a mix of sun and clouds with an approaching cold front during the evening hours expected to drop temperatures slightly across Long Island, the National Weather Service said.
News 12 Long Island meteorologist Rich Hoffman said most of Tuesday will be warm and dry, with daily highs ranging from the upper 70s to low 80s and a slight chance of showers and thunderstorms starting in the afternoon.
The chance of rain is about 20 percent, the service’s Upton office said, and Hoffman said the incoming cold front will push the effects of Tropical Storm Colin offshore and away from Long Island.
But that front will lower temperatures, too. Daily highs Wednesday and Thursday will be as much as 10 degrees cooler, in the low to mid-70s, he said.
For Tuesday, “Expect sun and clouds with a spotty shower or thunderstorm in the late afternoon,” Hoffman said.
Skies clear and winds pick up some, he said. Nighttime Tuesday and into Wednesday morning will be less humid, too.
There is the threat of routine coastal flooding on the South Shore bays of Nassau County and Queens, the service said in a special weather statement that runs 10 p.m. Tuesday until midnight. Shore roads are vulnerable to “brief minor flooding” because of the height of storm tide, the service said.
Wednesday gets mostly cloudy conditions with highs near 70s. There’s the chance of showers and storms, he said.
Thursday will be mostly sunny; daily highs climb a bit, into the low 70s.
