Warm, sunny conditions will continue today ahead of tomorrow's cold front. Ozone concentrations are expected to reach the Moderate/Yellow category in central and northwestern Oklahoma, but today's strong winds and moist airmass will help tamp down ozone elsewhere in the state. Locally higher particulate matter concentrations, up to the Moderate category, are possible in central Oklahoma; however, particulate matter is not expected to be widespread today. Tomorrow's cold front will help wash out a lot of pollutants and clear the air. The return of warmer conditions into the weekend will bring a renewed risk of high ozone concentrations.
