NEW YORK (PIX11) — The dangerous heat arrives on Wednesday as the heat index climbs well past 100 degrees across the tri-state region.

On Thursday, the actual air temperature looks to reach 100 degrees, and we could be in the hottest stretch that we have not seen in over 15 years.

NYC forecast and PIX11’s Weather Center

An extreme heat warning has been issued between Wednesday and Friday, as the heat index could approach 110 degrees. Indices this high can greatly cause heat-related illnesses like heat stroke or heat exhaustion. An extreme heat watch remains for Saturday, but it may just be a matter of time before it gets elevated into a warning.

A few isolated storms could drift south into the Hudson Valley from the north on Tuesday evening. Most sections look to be dry, but it will be a warm night as temperatures drop into the mid 70s.

Temperatures will soar into the upper 90s on Wednesday, but the tropical-like humidity will cause the heat index to soar to around 105 degrees in the city. The heat and humidity could also bring in a few gusty thunderstorms to flare up during the latter part of the day.

The core of the intense heat will be in place on Thursday and Friday as the actual air temperature reaches 102 and 103 degrees. The heat index could approach 110 degrees at the height of the day.

Temperatures will back off a touch on the Fourth of July, but it will still be a tough day as temperatures top out in the upper 90s. It will likely still feel like 105 degrees or so during the latter part of the day.

A few thunderstorms look to develop in the afternoon, but hopefully will settle down in the evening as the fireworks displays get underway.
