| Yesterday and overnight, a band of heavy
rain passed through Oklahoma and washed away pollution. That band will progress through eastern
Oklahoma today, and occasional additional rain showers will follow and
maintain good air quality for a couple of days. A cold front will bring an autumnal chill,
dry air, and northeasterly winds behind this system, and the bright sunshine
will foster ozone formation.
Temperatures will recover early next week as winds shift to southerly,
and the return flow may bring pollution from Texas northward. As next week progresses, summerlike warmth
and dry conditions may lead to high ozone. |
