The temperature in Philadelphia surpassed the 90-degree mark today for the first time since July.
By shortly before 2 p.m., the mercury at Philadelphia International Airport this afternoon had reached 92 degrees, according to the National Weather Service. The heat index at the airport hit 100, the weather service said.
It's the city's first 90-plus day since July.
"Conditions will remain very warm and humid," a weather service forecast discussion said this morning.
The last time Philadelphia recorded a temperature in the 90s was July 21, when the mercury hit 91.
The city didn't see temperatures in the 90s for all of August -- just the sixth time that's happened in the past century, according to the weather service.
The highest temperature of that month was 89 degrees, recorded on Aug. 21 and Aug. 27. In September, the hottest days have been Sept. 1, with a high of 89, and Tuesday, which had a high of 88.
August usually sees six to seven days with temperatures in the 90s, according to weather service data. One or two 90-plus days are typically recorded in September. Last year, September saw one 90-degree day, with a high of 91 recorded on the first day of the month.
The forecasted high of 92 for today is 12 degrees above the normal of 80, but still far short of the record 98 degrees, set in 1983.
Thursday is also expected to be warmer than normal, with an expected high of 87 degrees. There's also a chance of showers and thunderstorms, particularly after 2 p.m., the weather service says.
Some of the storms could bring strong wind gusts and heavy rain, forecasters say.
Friday and the weekend should be much cooler: Forecasters are expecting highs of 71 degrees Friday and Saturday and a high of 76 on Sunday. Overnight low temperatures could dip into the lower 50s.
