ALERTS: EXTREME HEAT WARNING is in effect from Wednesday at noon through Friday at 9 p.m. An EXTREME HEAT WATCH remains in effect for Saturday. An AIR QUALITY ALERT is in effect for 11 a.m. to 11 p.m. Wednesday and will be extended beyond that. Stay hydrated and safe!
TONIGHT AND OVERNIGHT
This evening is still comfortable overall - warm and noticeably humid - under a partly cloudy sky. There will be a chance for a passing shower, but most of the evening is dry.
There will be a better shower or brief downpour chance after midnight overnight and through around 5 a.m. The best chance will be in Suffolk County, but a shower is possible in Nassau County, too. Otherwise, partly cloudy with lows in the upper 60s to mid-70s into Wednesday morning.
EXTREME HEAT ARRIVES WEDNESDAY
Wednesday through at least the Fourth of July on Saturday will be a stretch of dangerous heat and humidity on Long Island. Believe it or not, heat is the number one weather-related killer. So, enjoy the outdoors smartly during this stretch. It can feel like anywhere from 95 to 110. You can find some relief at the South Shore and East End beaches, but you still will need to drink plenty of extra water, take frequent breaks in an air-conditioned environment and limit strenuous outdoor activities - do whatever you can to keep your body cool.
Air quality will also be poor throughout the rest of the week. Those with pre-existing respiratory or heart-related illnesses will be most affected, but this is the type of heat and humidity that will affect anyone if you are not going. Please also check on your pets and remember to check cars for anyone or any pets before walking away.
STORM CHANCES THIS WEEK
While no day is a washout this week, the building heat and humidity will lead to a few scattered shower and thunderstorm chances. There will be a few widely scattered showers overnight Tuesday night and into early Wednesday morning before 5 a.m. A few more scattered showers and a thunderstorm can pop-up anywhere Wednesday afternoon and evening.
Thursday will be dry, but an isolated shower and thunderstorm chance returns Friday. Saturday, the Fourth of July, can have a few pop-up showers or storms in the evening that can temporarily impact outdoor plans. Most of the morning through mid-afternoon should be dry.
The News 12 Storm Watch Team will continue to keep you updated on all of this through the week, so check the News 12 app for frequent updates.
