Heat will stay away from Pittsburgh, but part of the weekend is likely to be unsettled.
Temperatures will average near normal this weekend with Sunday being the warmer of the two days. Temperatures typically range from a low near 60 to a high in the lower 80s F around the Pittsburgh metro area.
A storm system from the Central states will cause rain to bulge northward for a time and brush the region Friday night and Saturday.
How much rain falls Friday night into Saturday and how quickly the weather clears on Saturday night and Sunday will depend on the strength of that storm system.
According to Northeastern Weather Expert Dave Dombek, "A stronger, rather than weaker storm would allow more rain to fall farther north on Saturday but would also allow more drying and hence clearing farther south on Sunday."
Clouds and spotty showers could linger in part of the area on Sunday, especially south of the city.
"The daylight hours are long and the sun is strong this time of the year, so odds are in favor of clearing progressing across the region on Sunday," Dombek said.
