Coolest morning in a month

The string of calendar days in which the temperature failed to get below 70 degrees officially in Philadelphia finally ended at 30 yesterday.

That topped the reocrd of 26 that was set back in 1876, when the official temperatures were measured downtown. The Philadelphia International Airport station has its own heat-island issues, but such consistent overnight warmth ranks as impressive, not to mention expensive for energy consumers.

The low reading we've seen so far today, 63, would be the lowest temperature in Philly since June 22. We probably all forgot that the meteorological summer got off to a cool start.

Although no new high-temperature records have been set in July, today will mark only the third day of below-normal temperatures.

As of today, July is running about 4.5 degrees above normal overall, but this end-of-month cool-down might be enough to knock it out of the top 10 lists for hot Julys.

Still, a banner month for PECO.
