Meteorologists believe this week will be a wet one, though rainfall accumulation isn’t expected to rise to flooding levels, according to the National Weather Service.
Monday will bring a light rain early in the day with a steadier rainfall in late morning and early afternoon, said Jay Engle, a National Weather Service meteorologist in Upton.
“There could be a rumble of thunder,” Engle said.
Fog is expected along the East End and the South Shore, he said, with temperatures near 60 degrees — about 10 degrees below normal.
“The rain will be moving from the south and by the time it gets to Long Island, it will most likely be toward daybreak — with it starting in Nassau and spreading into Suffolk,” meteorologist Tim Morrin said. “It’ll impact the commute, with rain heavier at times, but it’s hard to forecast exactly when.”
The rain should taper off Monday night around midnight, with temperatures in the upper 50s, he said.
Tuesday will bring brief morning sunshine during a mostly cloudy day with high temperatures near 70 before rain takes over again at night.
There is an 80 percent chance of precipitation on Wednesday, a 50 percent chance of scattered thunderstorms on Thursday and a 60 percent chance of rain on Friday, Morrin said.
