After a break from the high humidity into Friday, the risk of spotty thunderstorms will return to the Pittsburgh area this weekend.

A push of air from Ontario and the upper Great Lakes will shave temperatures and humidity levels a bit into Friday. The reduction in humidity will translate to little or no popup shower activity.

However, as the flow swings around to the south and southeast over the weekend humidity levels will creep back up. Strong sunshine and higher moisture levels will lead to an increased risk if showers and thunderstorms this weekend, especially during the afternoon and evening hours.

Warmth will build during the first part of next week, before cooler air moves in over the Independence Day weekend.

Both the transition to warm and humid conditions and then to cooler weather could be accompanied by severe thunderstorms. The details will unfold over the next few days.
