NEW YORK — The tri-state area could see its first heat wave as a stretch of 90-degree days is expected through the weekend and into the early part of next week.

An official heat wave occurs when three consecutive days of temperatures above 90 degrees are recorded.

Saturday's forecast is mostly sunny with highs in the mid-90s.

The National Weather Service issued a Heat Advisory in New York City for Sunday and Monday, as heat indices are expected to climb into the upper 90s.

The worst of the heat will arrive on Monday. While the air temperature may hold in the mid-90s, the high levels of humidity will make it feel more like 100 degrees.

The city Emergency Management Department is working closely with the National Weather Service, Con Edison and PSEG Long Island to monitor the heat as well as the power grid.

Widespread heat coupled with the high electric demand caused by air conditioners can sometimes cause scattered power outages.

For those who do not have air conditioning, the city’s cooling centers will also open, but with new rules mandating face coverings and social distancing because of the COVID-19 pandemic.

The heat and humidity will continue into the middle part of the week, but with an increasing risk of afternoon showers and thunderstorms.

Relief from the stifling heat and humidity likely won't come until Thursday or Friday. Temperatures will remain in the upper 80s to around 90, but the humidity should trail off by then.
