The first major heat wave of the summer will bring another day of dangerously high temperatures to the East Coast on Wednesday before relief moves in. The oppressive heat shattered records across the Northeast on Tuesday.

It's officially the first heat wave of the season​ in NYC. High temperatures hit the 90s Wednesday, for a third day in a row​.

It is the second year in a row that a heat wave has hit the New York City region earlier than usual, as global warming is projected to worsen heat waves and make them more frequent, climate experts say.
