Yes and it really does not happen in June and even moreso after so much rain. But add this caveat, we rarely ever see our highest temperatures in June, this will probably be an appetizer for heat even more extreme in July.
This is climo history, when you have heat starting in the latter part of June it doesn't peak until July. Heat after June 20 usually indicates a very hot and very long summer. 1966, 1980 and 1993 being cases in point.
That really is an unusual streak for Philly, is that their all time longest?
I can't imagine why Philly hasn't hit 100 over 13 years lol. Can't use the sea breeze excuse.
From what I read that massive August 2003 outage was caused by a squirrel chewing on the power line up near Buffalo that caused a power cascade across the entire region from Michigan to the east coast and up to Canada, 55 million without power because of one hungry squirrel lol.
