PHILADELPHIA (CBS) – The temperature reached 90 degrees in Philadelphia on Wednesday for only the third time this year.

In addition to the heat, the humidity remains high and dew points around the region topped off in the 70s, making it feel oppressive this afternoon.

The high moisture content is fueling a strong line of thunderstorms in central Pennsylvania and those storms will move through our area between 9PM and midnight. As the front passes late tonight, downpours with frequent lightning and gusty winds are possible, as well as street ponding and flooding in poor drainage areas. Lingering showers are likely after midnight as the system pushes off the coast.

Thursday morning will start with clouds, but sunshine will return by the afternoon and the humidity will be slightly lower. The high on Thursday will be 88, just a few degrees above the average of 85.

Temperatures stay near average with sun and clouds on Friday with a northerly wind will decrease the humidity a bit more.

The weekend looks good with partly sunny skies both Saturday and Sunday with temperatures in the mid 80s.

Next week, the humidity will climb up again and so will the temperatures. A few thunderstorms are possible by the middle of next week and the start of July looks hot and humid and stormy.
