Forecast Discussion: Ozone is trending towards green for all zones this Tuesday. Plenty of moisture and scattered clouds with precipitation are helping to keep dew points high and ozone low. A change for Wednesday is in store. Dew points will drop, skies will clear, and temps will rise about 5 degrees. This pattern is more ideal for ozone production as an upper level ridge settles into the Southeast US to help stabilize the atmosphere. With less movement comes a greater risk for pollution pooling and large ozone jumps from Tuesday. However, the atmosphere is currently clean enough that the ozone jumps will likely remain below the threshold level and keep all zones CODE GREEN for Wednesday.
