While heat still remains the main weather story, more summertime pop-up thunderstorms are expected this afternoon and evening.
With sufficient instability in place, a storm or two may be able to briefly become severe. Wind gusts up to 60 mph is the main threat. Most will be below severe limits, producing briefly heavy rain and frequent lightning.
Remember, if you hear thunder, you are close enough to be struck by lightning. Head indoors and wait for the storm to pass.
