For 9/27/2023
[ The forecast is updated daily by 3:30 pm EDT. ]
As of mid-afternoon on Tuesday, all forecast regions are trending towards a code green finish for surface ozone concentrations. For Wednesday, similar conditions will carry over. Wind is forecast to be northeasterly ranging from light to a gentle breeze throughout the forecast regions. Heavy cloud cover in the morning will transition into mostly cloudy skies in the afternoon for all areas. This cloud cover coupled with a decent amount of moisture in the atmosphere will help ward off enhanced ground-level ozone production. A chance of showers in the coastal regions during the day will stifle any ozone concerns to be had in those areas. Overall for Wednesday, all forecast regions should finish in code Green once again.
