After a beautiful start to the workweek, summerlike heat is sticking around across parts of Long Island and the tri-state area today. We’re looking at plenty of sunshine with temperatures soaring into the 80s and even a few low 90s inland this afternoon. If you’re heading to the beaches along the South Shore, or East End or immediate coastline, temperatures will be noticeably cooler, mainly in the 70s, thanks to the ocean breeze. It’s a perfect beach day, but don’t forget the sunscreen — the UV index is running very high — and remember ocean water temperatures are still only in the 50s, so swimming will definitely feel chilly.

Tonight stays very mild with partly cloudy skies and temperatures only falling into the upper 50s and mid-60s. It’ll be a great evening for outdoor plans, whether it’s grilling, dining outside, or taking a walk after sunset. The warm and somewhat humid air will continue to build heading into Wednesday.

Wednesday starts with sunshine, but clouds will increase during the afternoon as a cold front approaches from the west. We’ll be watching for a few pop-up showers and thunderstorms late in the day and into the evening hours. Some storms could bring brief heavy downpours and gusty winds, so keep an eye on the forecast if you have outdoor plans on Wednesday evening. Despite the storm threat, temperatures will once again climb into the 80s and low 90s inland, while shoreline communities stay cooler in the 70s.

The cold front moves through Wednesday night with scattered showers and thunderstorms before cooler air settles in for Thursday. Expect partly sunny skies Thursday with highs only around 70 degrees, a big change from the early-week heat.

Friday turns mostly cloudy with the chance for a few late-day showers and temperatures staying in the 60s. Unfortunately, the holiday weekend currently looks unsettled with clouds and scattered showers both Saturday and Sunday and highs mainly in the upper 50s and 60s.

Memorial Day itself looks mostly cloudy with temperatures near 70 and the chance for a few passing showers, so keep the umbrella nearby if you’ll be heading to parades or barbecues.
