The high on Thursday in Philadelphia was 97, coming close to matching the record of 98 from 1995. Surrounding communities felt the near-record temperatures, too. Humidity and sunshine made it feel from 100 degrees or more. The feels-like temp in Philly Thursday topped out at 108.

Scattered, severe storms and showers moved through the region Thursday evening, in northern and western neighborhoods first, then through Philadelphia and its suburbs.

The NBC Sports Philadelphia broadcast of the Phillies vs. Nationals game caught a lightning strike at Citizens Bank Park shortly before 9 p.m. The rain wound up cutting the Phillies' win short after 5 innings.

Friday won't be as hot, but still feeling like the triple digits with isolated scattered storms, especially in Delaware and South Jersey. Those thunderstorms later Friday and Friday night are expected to produce downpours and possibly damaging wind, however, it does not look like the storms will be widespread. The Friday storms, however, could be slow moving in certain areas.

The highs this weekend are expected to still get into the upper 80s Saturday and lower 90s Sunday. Should the high hit 90 on Saturday, the heat wave would stretch into next week.

Some isolated showers and storms can't be ruled out either day.
