September is starting with an extended dose of summer.
Highs at least in the upper 80s are expected through Saturday, with Tuesday's high potentially matching the high for all of August -- 93.
Humidity will be worse today and Tuesday than the rest of the week, with a chance of scattered showers today and a chance of thunderstorms from midafternoon into the evening both days.
Expect clear or mostly clear skies Wednesday through Friday, with a chance of thunderstorms Saturday.
Temperatures should break by Sunday, when the high is expected to be in the mid to upper 70s.
Most Septembers see at least one day in the 90s in the Philadelphia area. though four of the last 10 Septembers topped out in the mid to upper 80s.
The summer's high was 96 on July 2.
