Hot and dry conditions will continue to be the norm this week across Oklahoma. Ongoing fires in Texas and eastern Oklahoma will contribute to Moderate/Yellow particulate matter concentrations for the McAlester, Tulsa, and Lawton areas. At the same time, southerly winds will support transport of ozone from north Texas into southern and central Oklahoma over the next couple days, with the potential for "Unhealthy for Sensitive Groups"/Orange ozone concentrations in the Lawton and OKC metros. Ozone concentrations in the Moderate category will continue to dominate the state. A cluster of storms from the Gulf may help wash out some pollutants in Texas later this week, which would send cleaner air north to Oklahoma.
