The heat wave experienced across Western Pennsylvania was a historic one.

According to a tweet posted by National Weather Service Pittsburgh late Monday night, the peak temperature of 60 degrees across the Pittsburgh area made it the 6th-highest Christmas temperature ever recorded dating back to 1871.

The highest Christmas day temperature ever recorded was back in 1895, when Pittsburgh had a reading of 67 degrees on December 25. The 66 degree holiday of 1982 was a close second.
