As we get into the afternoon, our dewpoints will rise into the low to mid-70s, meaning there will be a lot of moisture in the air.

The more moisture that's in the air, the slower sweat evaporates and cools down the body. This will easily make it feel like the upper 90s outside, but as mentioned earlier, it could reach over 100˚ in areas.

Fortunately, Sunday isn't looking as bad, but long-term heat is still possible as we're in the heart of the hottest period of the year, on average.
