Isolated thunderstorms are in the forecast for Sunday, followed by increasing heat and humidity Monday and Tuesday, according to the National Weather Service. Additionally, the state has issued an air quality advisory for Sunday until midnight for Long Island, as well as New York City and all the way through the upper Hudson Valley.

The air quality index (AQI) is predicted to be above 100 in much of New York state on Saturday, and could reach 135. Alerts are also in place for parts of New England. The AQI measures the severity of pollution in the air and categorises health risks. The higher the number, the more unsafe the air is to breathe.

An air quality alert has been issued by the New York State Department of Health this weekend due to smoke from wildfires in Canada. The air quality health advisory covers New York City and the surrounding metropolitan area,
