Midweek showers expected in otherwise lovely week

A midweek shower will be the only blip in an otherwise pleasant summer week on Long Island -- although denizens of Nassau County's South Shore should gear up for some minor "supermoon" flooding Sunday night, according to the National Weather Service.

Sunday will be in the mid-80s, with mostly sunny, dry skies, said Joey Picca, meteorologist with the service's Upton bureau.

Sunday night will reach into the mid-50s in the Pine Barrens, and into the low to mid-60s elsewhere on Long Island.

The National Weather Service issued a coastal flood advisory for the back bays along the South Shore of Nassau County. The advisory is in effect from 7 to 10 p.m., and is due to a combination of a full "supermoon" coming at high tide, Picca said.

"With the full moon, we have higher than normal tides," Picca said. "It won't take much to get those water levels to the point where we could have some minor coastal flooding."

The "supermoon" -- technically a perigee moon -- occurs when a full moon makes a slightly closer path to Earth, he said.

Monday will be slightly cooler, with mostly sunny skies and highs in the low 80s.

Clouds will begin to gather on Monday night -- the first hints of a storm system to come, Picca said. Lows on Monday will be in the 60s.

Tuesday will cool down further, with highs in the mid- to upper 70s. Clouds will increase throughout the day, with an increased chance of showers during the second half of the day, Picca said.

Showers are likely Tuesday night, bringing with them a chance of thunderstorms -- with some heavy at times, Picca said. Lows will be in the upper 60s.

Highs on Wednesday will be in the upper 70s to near 80, with showers likely.

The chance of showers decreases on Wednesday night, with lows in the low to mid 60s.

Thursday will be drying out as the storm system moves to the northeast, Picca said. Highs will be in the mid- to upper 70s -- below normal for this time of year, he said.

Thursday night will be in the low to mid-60s, while Friday will be cool and pleasant, with highs in the mid- to upper 70s.
