Heat Wave to Build Over Northeast US This Week

Air conditioning units and swimming pools will have their work cut out for them this week across the northeastern United States as a heat wave sets up over the region.

It will feel down right uncomfortable for many along the Interstate-95 corridor as temperature and humidity levels climb through the first half of the week and remain high through Friday.

According to AccuWeather Meteorologist Edward Vallee, an area of high pressure is responsible for this week's heat wave as it pumps hot, muggy air over the region from the South.

Areas from Baltimore to New York City and even up to Boston are forecast to climb above 90 F on a daily basis, while areas farther inland top out closer to the 90-degree mark.

Many cities in the Northeast have already hit 90 F multiple times this year, but this heat wave could bring the longest stretch of 90-degrees days so far this year.

When the high humidity and scorching sunshine are taken into account, AccuWeather.com RealFeel® temperatures can easily surpass 100 F.

"The climax of this heat will likely occur Wednesday, with temperatures well into the 90s, and RealFeels approaching 110 in some spots," said Vallee.

The mercury may even flirt with the triple digits around the peak heat of the middle of the week.

Temperatures are likely to fall short of breaking long-standing records, but the stifling heat can still be dangerous.

Every year there are more heat-related fatalities in the United States than there are during frigid arctic outbreaks, according to the National Weather Service.

Some of these occur when people leave their children unattended in a car during the oppressive heat. Even with windows cracked, temperatures can soar to dangerous levels in a matter of minutes.

Staying hydrated and wearing sunblock is also important when it comes to protecting yourself from the dangers that a heat wave brings.

"If people have to be outdoors during the peak heating hours each day, they should take breaks in the shade or indoors if they are able to do so," said AccuWeather Senior Meteorologist Danny Pydynowski.

The intense heat should begin to fade heading into the upcoming weekend with highs in the 80s rather than the 90s.

These temperatures are right around normal for the end of July.

This cool down should give residents in the Northeast a break from the heat and humidity heading into the opening days of August.
