A weak area of low pressure with tropical origins over north-central Georgia will maintain a very moist air mass over much of the forecast area the rest of Wednesday. Plentiful cloud cover and numerous showers will help to hold 8 hour ground level ozone concentrations well within the green category once again. A cold front will stall over the central part of the state on Thursday, then dissipate. Once again, abundant clouds and showery weather will keep the region within the green category.
