STRONG TO SEVERE STORMS POSSIBLE TUESDAY

Enjoy the beautiful weather while it's here. Today features wall-to-wall sunshine, comfortable humidity, and temperatures topping out around 80 degrees, making it a fantastic day to get outside. The air will feel refreshing compared to recent stretches of muggy weather. The only thing you'll want to keep in mind is the UV index, which remains on the high side, so don't forget the sunscreen if you'll be spending extended time outdoors.

The unsettled weather continues Tuesday night into Wednesday as a cold front moves through the region. Expect scattered showers and thunderstorms, with a few storms capable of producing brief heavy downpours and gusty winds. While not everyone will see severe weather, it's a good idea to stay weather-aware from late Tuesday through Wednesday morning in case stronger storms develop. High temperatures on Wednesday will climb into the lower 80s despite the clouds and occasional rain.

Looking ahead, the forecast improves nicely as we head toward the end of the workweek. Sunshine returns for both Thursday and Friday with lower humidity and pleasant summer conditions. Afternoon temperatures will be in the 80s, making for two great days to wrap up the week with plenty of sunshine and comfortable weather across Long Island.
