Issued on: September 17, 2025
Above average temperatures with gentle south-southwest winds. There are chances of rain/t-storms along the western OK-KS border, then moving southwards through the end of week. Smoke from wildland fires will continue to elevate airborne particle pollution levels through the end of the week. Air quality will be diminished in most regions, with PM2.5 being the pollutant of concern in most places. Urban areas and along/east of I-35 are likely to experience higher air pollution levels; AQI scores will remain in the Moderate range. The passage of a cold front across the state, through Friday, should bring some relief to breathers by mixing away a good amount of any lingering pollutants from the surface.
