Scattered rain showers wash some pollution from the atmosphere.  A storm on the Canadian prairies, however, will induce stronger southerly winds, which will bring moist maritime air and ozone pollution from Texas into Oklahoma.  When sunshine persists through the afternoon in or downwind of an urban area, ozone may reach the moderate category.  On Monday, the southerly winds will diminish, and with only isolated rain showers, ozone may build well into the moderate category in urban areas.  Scattered showers will resume next week and lead to an improvement in air quality.
