After three days of heavy rain, a cold front brought clean Canadian air, an autumnal chill, bright sunshine, and good air quality for today.  Pollution buildup beneath the frontal inversion may lead to an increase in moderate ozone, and southerly winds resume on Sunday.  A tropical storm on the Pacific coast of Mexico will feed more moisture into Oklahoma, so another episode of heavy rain will develop toward the later part of next week and restore good air quality.
