Ozone conditions today will reach the Moderate/Yellow category in the OKC and Tulsa metros and along the I-35 corridor. A cold front will move across Oklahoma on Thursday, bringing scattered storms, widespread cloud cover, and milder temperatures to the state. These conditions will help limit ozone formation to the Good/Green category statewide tomorrow. Following the front, ozone conditions will return to Moderate levels beginning on Friday and lasting through the weekend, as warmer temperatures and clearer skies return. Although localized concentrations of smoke may reach the Moderate category, particulate matter concentrations are expected to remain in the Good category beginning tomorrow.
