Saturday: Be Aware of Heat Index and Scattered Thunderstorms
Same forecast. Again.
The dewpoint will hover around 72º all day, making for a heat index just under 100º.

Maybe.
Why?
Most summertime afternoon storms occur because of the heat-of-the-day. Cloud cover has kept the highs down, interrupting/delaying this storm-making process.
