The National Weather Service issued several advisories covering most of the Channel 11 News viewing area during a stormy Fourth of July.

Unsettled atmospheric conditions sparked pop-up thunderstorms throughout the evening despite no organized line of turbulence. Fortunately, the worst of it avoided downtown Pittsburgh, allowing the city's annual fireworks extravaganza to go on as scheduled.

There were plenty of natural fireworks on Tuesday night into Wednesday morning as well, thanks to lightning, thunder and more than an inch of rain. In addition to the high volume of rain, the strong storms across Western Pennsylvania toppled power lines with some homes being struck by lightning.

High temperatures on Independence Day climbed into the mid-90s with the heat index pushing 100 degrees. As fireworks lit up the Steel City, temps were still in the mid-80s. Daily highs in the 90s are expected into the weekend with slight cooling on Sunday.
