At 3:46 p.m., officially the temperature topped out at 97 at Philadelphia International Airport, impressively hot, but 2 shy of the June 21 record, 99.
Not that it was a pleasant day, but the heat index was a shade less ferocious than anticipated, maxing out at 100 in the hourly observations.
Next up will be a mighty uncomfortable overnight, with the forecast low a sultry 80. That would be a record-high minimum for the day.
But it's quite possible, perhaps even likely, the temperature will drop below 80 before 11:59 p.m. tomorrow, wiping out any daily record.
