A significant and potentially dangerous heat wave is forecast from the last day of June on Tuesday into Independence Day weekend. High temperatures in the 90s to low triple digits, combined with high humidity, will result in maximum heat index values over 100 degrees in many parts of Pennsylvania. The nights will be warm and muggy, with overnight lows holding in the 70s. There is also a risk for thunderstorms to develop in the hot and humid airmass, but most of the week will be hot with little relief.
