Philly: Storms to Accompany, Then Break Heat at Midweek

As temperatures top the 90-degree Fahrenheit mark at midweek, showers and locally severe thunderstorms will crash through the Philadelphia area.

How hot it gets Wednesday will depend on the amount of sunshine versus the amount of clouds and storms that come cascading in from the Great Lakes.

There is the potential for some communities to be hit hard with strong wind gusts, torrential downpours and frequent lightning strikes during the afternoon and evening hours.

Highs will be well into the 90s Wednesday. However, the high humidity accompanying the heat will push AccuWeather RealFeel® temperatures to near 100 in the afternoon.

The temperature reached 93 Tuesday at Philadelphia and set a new high temperature mark for the year so far. The latest Philadelphia has hit 90 in the summer season was on July 14, 1972. On average the first 90-degree temperature occurs during late May.

Cooler and less humid air will push southward from Eastern Canada late this week.

Current indications are there will be enough southward push to drive away showers and thunderstorms for a brief time. However, as this push backs off over the weekend, showers and storms are likely to return.
