Heat wave looms for I-95 corridor of Northeast

Philadelphia and Washington, D.C., have the potential to string 90-degree highs each day through this weekend and beyond, while New York City is projected to approach or top 90 from Tuesday through Saturday. This would give Washington, D.C., its first heat wave of the summer. Boston also could sneak in with as many as five 90-degree days in a row this week.

AccuWeather Global Weather Center – July 19, 2022 – An extended heat wave is in the forecast for the Interstate 95 corridor of the northeastern United States, AccuWeather forecasters say. The building heat will bring a prolonged stretch of 90-degree temperatures to several major cities that have not experienced many prolonged heat waves so far this summer.

The National Oceanic and Atmospheric Administration (NOAA) defines a heat wave as “a period of unusually hot weather that typically lasts two or more days” and also notes that, in order to qualify as a heat wave, “temperatures have to be outside the historical averages for a given area.”

In the Northeast, meteorologists typically define a heat wave as at least three consecutive days on which high temperatures reach 90 F or greater.

Both New York City and Boston typically have about a week’s worth of days with highs of 90 or better by the middle of July. The Big Apple has been on track with this through July 17, but Beantown has tallied only two days of 90-degree weather so far. Washington, D.C., has picked up a dozen days with 90-degree heat as of July 17, which is a few below the average of 16.
