Ongoing heat and humidity will provide fuel for isolated thunderstorms this afternoon and tonight. The main hazards with any strong to severe storm would be lightning, gusty winds, and hail. Not as hot or humid for Independence Day, but the afternoon will bring another chance for an isolated shower or thunderstorm. Coverage should decrease towards the evening hours with a more comfortable night in store.
