In the wake of drenching rainfall on the East coast, spotty showers and cool air are in store for Pittsburgh, through the weekend.
The large storm system responsible for the rainfall this past week was located hundreds of miles to the west, over the Great Lakes.
The storm is forecast to weaken slowly and wander eastward into early next week.
As this happens it will push the plume of Gulf of Mexico and Atlantic Ocean moisture off to the east. However, a zone of cool air and spotty, light showers will settle into the region.
Daytime highs through Sunday will be within a few degrees of 60 F.

Very warm weather may attempt to break into the region for a few days later next week, unless a zone of clouds, showers and thunderstorms develops nearby.
Travel restrictions are already in place in advance of the blizzard set to wallop the northeastern United States.
