The first real heat wave of the summer is leaving its mark in the record books.
Dozens of records have fallen this week in cities from the Plains to the Eastern Seaboard; some of these records had been on the books for more than a century.
Meanwhile, high humidity made it feel more like the 105 to 110 for many areas from the Midwest to the East.
The heat and humidity became "squeezed" off the East Coast due to an approaching cold front, marking the end of the heat wave.
That front also helped spark some nasty thunderstorms before the day was out on Friday.
Here is a look at some of the more noteworthy record high temperatures from the heat wave:

The veil of night didn't offer much relief from the summer sizzler.
Heat that built up during the day was slow to escape in many metropolitan areas/concrete jungles from Kansas City to Boston. As a result, temperatures failed to fall much below 80 in many areas all night.
Even more impressive, AccuWeather.com RealFeel® temperatures, which factor in humidity, stayed at or above 90 in a few cities through the nighttime hours.
Here is a look at some cities that failed to fall below 75 for at least a couple of mornings this week:
