Pittsburgh: Pleasant until weekend rain
A stray shower is possible Wednesday with the best chance in the Laurel Highlands.
A brisk, northerly wind today will keep temperatures in the 70s with low humidity. Temperatures will warm into the weekend with better rain chances by Sunday.
First Day of Steelers Training Camp
Mostly cloudy skies but low humidity is the story for Wednesday as cooler and less humid air spills in from Canada. A stray shower cannot be ruled out today, especially into the Laurel Highlands, but the weather should cooperate for the first day of training camp in Latrobe. Temperatures will be in the 70s with the shower chance not starting until practice is likely done for the day.

A pleasant first day of practice in Latrobe with a shower chance as you are heading to your car.
Weekend Rain Chances
The next, best chance at rain arrives late Saturday into Sunday. A system will start to our southwest Saturday. It will slowly clear the area on Sunday to take rain chances with it. We will mostly see rain showers with a thunderstorm or two possible. At this point, severe weather is not expected.

Rain arrives late Saturday and lasts through most of Sunday.

We dry out and warm up heading into next week with more rain and storms possible by the middle of next week.

A pleasant end to the week before a soggy second half of the weekend.
