There's plenty of high school graduations across the Northern Tier of Pennsylvania Friday and Saturday and it looks a bit unsettled heading into the weekend. A cold front will push through the region Friday evening with the chance for thunderstorms. We're also expecting hazy sunshine with temperatures into the mid 80s. Cooler conditions will arrive on Saturday with lingering clouds and a slight chance for a shower. Temperatures on Saturday will top out in the lower 70s. Congratulations to all of the graduates!
