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:

As Expert Senior Meteorologist Alex Sosnowski pointed out earlier in the week, relief is on the way to the big cities this weekend, and next week unseasonably cool air will set up shop across the East.
Following a wet, mild Christmas Eve across much of the Northeast, a blustery Christmas Day is on the way.
While lacking across a large part of the United States on Christmas Day, arctic air is set to make a comeback during the final days of 2014.
While many bowl games will be played in warmer locales this year, there are others that will face cold and potentially wintry conditions in the Midwest and Northeast.
A winter storm will impact the United Kingdom and central Europe for Boxing Day and the holiday weekend.
A potent Christmas Eve storm is also threatening the Ohio Valley with violent thunderstorms.
While blustery winds will usher in colder air on Christmas Day, milder air will then quickly return to Pittsburgh on Friday.
