Cold Summer Leads To Leaves Changing Colors — In August!

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.

90-degree days running 40% below normal in DC…

There’s one constant about D.C. summer, and that’s a lot of hot days. Right?

Not always.

While 2014?s average temperature for meteorological summer (Jun-Aug) is running fairly close to “normal,” as defined by the 1981-2010 climate period, it’s undoubtedly been among the more pleasant in recent memory when it comes to daytime heat.

90 degree days since 2004.

With only 16 days featuring high temperatures at or above 90 degrees this year, we’re a week behind last year’s tally year-to-date, and 32 days (more than a month!) behind the pace of the scorching 2010-2012 summers.  The average year-to-date total is around 29.

Of course, the crazy summers that kicked off the 2010s averaged about three weeks more 90 degree days than the average around 36 days. 2010 even gave us a tie for the most on record at 67.
