For 4/25/2024
[ The forecast is updated daily by 3:30 pm EDT. ]
As of Wednesday afternoon, all forecast regions are trending towards a code yellow finish with the exception of the Midlands, which is trending towards a code green finish. For Thursday, high pressure builds back into the region in the wake of the frontal passage Wednesday. Mostly sunny skies and a return to seasonably average temperatures across the state look to be on the cards. Winds will be slower than experienced earlier in the week as they slow to a light breeze from the North. Drier air will be advected into the forecast regions, steered on by the upper air pattern. Overall the pollutant dispersion characteristics appear to be the worst it has been this week and should begin a pattern of air mass stagnation for the coming days. For Thursday, all forecast regions are projected to peak in code YELLOW except Pee Dee which is expected to peak in code GREEN.
