Even with a full day of sun through much of the state, much of the state will remain in the upper green category on this Saturday. Weather conditions will become somewhat uncertain this evening through Sunday due to upstream energy penetrating through a drier airmass throughout the Carolinas. Expect a mix of clouds and sun with a chance of storms on Sunday. What is rather certain is that horizontal mixing will remain moderate to strong with 20-30mph transport winds from the west and southwest. This should allow cleaner air to penetrate in from the west, and all zones should remain within the GREEN category on Sunday.
