From Joe D’Aleo via email:
It will be remembered for the heat wave and dryness in a large area, but some facts may surprise you.
June actually ended up cooler than the normal in BOS (Boston) (-1.25F) and even NYC (Central Park -0.4F) and southeast despite the heat blast the end of the month (-2.0F in Jacksonville). Dulles despite the late month heat wave was SLIGHTLY BELOW NORMAL (-0.6F) while DCA nearer the White House and Congress was (+1.1F) and Atlanta despite the all time record was just +0.1F.
In the west, predictably with the cold PDO eastern Pacific, it was another cool start to summer. Seattle ended up -2.6F, Portland -2.4F, Spokane -2.5F.
The preliminary Climate Prediction Center temperature analysis for the month showed the core of the heat was over the central Rockies with +7.6F in Denver. The heat nosed in a few plumes to the east most notable relative to normal over the Great Lakes (Green Bay +5.8F and ORD (Chicago O’Hare) +5F).
Looking at the CPC map above, you can clearly see this as a regional weather event, one driven by a pattern shift. There’s no “climate change” component to this just as there was not any in the 2010 Russian Heat Wave, where the media also went crazy trying to tie it to “global warming”. Readers may recal last summer, where the same sort of pattern set up in the USA: Blocking highs contribute to unusually hot July in the Great Plains – Anthony
