The all-time records for heat in the states of Delaware, Pennsylvania, New Jersey, and Maryland are all right around 110 degrees, and three of those state records were set on this date, July 10, back in 1936.

That day was the hottest on record in the Mid-Atlantic region. The New Jersey record of 110 was set in Runyon, about 25 miles northeast of Trenton. The Pennsylvania state record of 111 was established in Phoenixville, a few miles northwest of Valley Forge. The Maryland all-time state record of 109 was also set that day. No state record in Delaware, but the 103 in Wilmington was no picnic either.

Yes, we've had some hot summers over the last decade or so. But consider this: during that summer of 1936, 15 different states set their all-time records for heat, records that still stand today.
