PITTSBURGH (KDKA)- Pittsburgh is dealing with one of the coldest summers in history, and it's having an effect on the trees.
Friday morning temperatures fell into the 40s in Western Pennsylvania.
Meteorologists say these cold temperatures are leading to trees changing colors in the middle of August.
"This is extraordinary for August, and certainly is a reflection of the prevalence of cool weather," KDKA Meteorologist Dennis Bowman said.
Right now Pittsburgh is on pace for the 9th coldest summer since record keeping began in 1871.
A KDKA weather viewer took these pictures of the leaves already starting to change colors on the South Side of town, and other residents have noticed the same thing happening on the North Shore.
Marlene Evans says she is noticing the trees already changing along Water Street. They show yellow and red leaves already mixing in with the trees' green leaves.
Bowman says it is odd to see the golden yellow and red leaves already showing up.
The Polar Vortex pattern that we saw in January, also caused cold temperatures in July.
"There has been a frequency of cold fronts this summer, and the weather for June, July, and August has been substantially below normal," Bowman said.
