An Excessive Heat Warning is now in effect through Saturday for most of the Commonwealth, when late morning through early evening heat index values will commonly range 108 - 115 degrees (in the shade). If you're in the sun, it can feel another 10 to 15 degrees hotter on top of that heat index value because of the added sensory warming from radiation (sunshine) heating on your skin.
If you do have outdoor activities that need to be done into the weekend, please complete your tasks (when possible) before 10AM each day. Even in the evening, the heat index will still be dangerous!
