Heat: Toasting another record

The official high temperature crept to 90 yesterday in Philadelphia, marking the 52nd time this year that the maximum reading his hit at least 90.

The all-time record is 53, set in 1991, and it's possible it will be matched this afternoon. After today, one of those splendid September cool spells is due.

However, even if the 90-plus record isn't matched today, we'll go out on a limb of drying leaves and predict that the 1991 standard is toast.

The official high has hit 90 from Sept. 9 onward a total of 104 times since record-keeping began in 1974, 43 of those occurring after Sept. 14. 

Incidentally, the latest the temperature has ever hit 90 was on Oct. 10, in 1939. Coincidentally, 40 years later Oct. 10 would become the date of the earliest measurable snowfall in Philadelphia.
