SCATTERED RAIN CHANCE THIS EVENING
Have an umbrella with you just in case this evening! Weakening thunderstorms are approaching Long Island from the west this evening. Scattered showers and even a brief downpour with a rumble of thunder will be possible this evening and tonight as those continue to weaken and move east. Otherwise, mainly cloudy, warm and humid with lows into Friday morning only dropping into the upper 60s to lower 70s.
EXTREME HEAT, POOR AIR QUALITY AND STORMS THURSDAY
Thursday is the next weather day with multiple risks for Long Island. First, be safe with the extreme heat and poor air quality. You will feel the heat and humidity building quickly on Thursday morning. It will feel uncomfortable outside, but it will be a dry start to the day. With heat advisories posted, and now extended through Friday evening, and an air quality alert in effect Thursday, please do not overexert yourself and take breaks from the high heat and humidity.
That heat and humidity will act as fuel to help spark scattered downpours and strong thunderstorms in the afternoon and evening. This can impact the evening commute with scattered flooding and a chance for storm-related damage. A spotty thunderstorm is possible at any time in the afternoon and evening, but the best chance for any severe thunderstorms is likely to be after 5 p.m. Be safe and stay with News 12 Long Island for updates throughout the day on the storm chances and heat. An important thing to keep in mind is that not everyone will get severe weather, but the weather parameters for strong to severe thunderstorms are there for Nassau and Suffolk Counties on Thursday.
