For 9/22/2019
[ The forecast is updated daily by 3:30 pm EDT. ]
Ground level ozone concentrations are on track to peak within code yellow in the Upstate and green elsewhere. Expect a carbon copy forecast for Sunday with high pressure rather stalled. Sunny skies, low humidity, warm temperatures and a light south wind should produce an isolated minimal YELLOW reading in the Upstate on Sunday. However, all other zones should remain GREEN.
