PITTSBURGH – (WPXI) – A heat advisory is in effect through Friday evening. High temperatures Friday will be in the lower 90s, but the high humidity will make it feel close to 100°. Have a backup plan for outdoor events as heat will take its toll if you’re active outdoors for any length of time. Find ways to stay cool if you have to be outside. A few rounds of showers and storms are expected this weekend. Storms are possible Friday evening and will last on and off through Saturday. There will be many dry hours, however, any storm can bring damaging winds and very heavy rain. By Sunday, we’ll see a drier push of air from the north which will lower the humidity and cool us below average for early next week.
