Ongoing transport of Mesoamerican smoke and Saharan dust into Oklahoma is expected to keep particulate matter concentrations in the Moderate/Yellow category statewide through early next week. Furthermore, locally high particulate matter concentrations are expected to occur this weekend in tandem with July 4th celebrations. Ozone concentrations may reach the Moderate category this weekend along and east of the I-35 corridor as warmer, less breezy conditions settle in.
