July 16: Mostly dry again today but rainy season storms return Friday

The 18th heat advisory of the year brings a heat index up to 105°+, with Saharan dust and dry air limiting storm development. Storms will return Friday, potentially severe with wind gusts, lightning, and hail, while the National Hurricane Center monitors a 20% chance of tropical development in the northeastern Gulf, which could bring rain to northern Florida and coastal Carolinas.
