LI weather: Beautiful day but thunderstorm possible Wednesday

Long Islanders planning outdoor activities on Sunday can look forward to a nice and sunny summer day with only moderate humidity and no advisories for boaters, forecasters said.

But there will be an increasing risk of rip currents into the beginning of the week, according to meteorologists.

Sunday’s high is expected to be 83 in Islip and Coram and 80 in East Hampton. The high will be 81 in Cutchogue, 82 in Kings Park and 84 in Babylon. Lows will hover near 68 degrees, News 12 Long Island meteorologist Rich Von Ohlen said.

David Stark, a National Weather Service meteorologist in the Upton office, said beachgoers over the next few days should watch out for rip currents. Water temperatures were expected to be very comfortable at 74 to 79 degrees, he said.

“Today there’s a moderate risk and the threat becomes a little more into the early part of the week,” Stark said.

According to News 12, the rip currents expected over the next few days are due to a resurgent Hurricane Gaston churning out in the Atlantic.

More sunshine mixes with clouds Monday when it will be more humid and hot, with highs near 88 degrees. There’s a small chance for an isolated shower during the afternoon.

Mostly sunny skies return Tuesday, when highs are predicted near 82 and lows near 71.

Lots of sunshine continues for the middle of the week, when there will be a chance of a thunderstorm on Wednesday. Highs will be near 88 and lows near 72.

Morning showers give way to increasing sunshine on Thursday, when highs near 82 are forecast and lows will dip near 63.

Mostly sunny skies will end the workweek on Friday when highs will be near 77 and lows near 57.

“Generally overall, at least through Wednesday, we’ll be above normal and at the end of the week we’ll be close to or a few degrees below” average for the period, Stark said. “The normal for this week is around 79 and the low 64.”
