A powerful hurricane off the Pacific coast of Mexico will feed moisture into the southwest monsoon.  As a result, heavy rain returns to Cimarron county, and showers in western Oklahoma ensure clean air for today.  East of the rain, partial sunshine and a vestigial frontal inversion will allow ozone to reach the moderate category.  South of the stationary front, Saharan dust constitutes moderate fine particulate matter.  Winds will turn southerly and allow pollution from Texas to move northward for the weekend, but an combination of an upper-level trough, the monsoon, and the hurricane in the Pacific Ocean will bring rain to a larger portion of Oklahoma next week.  Some models suggest a tropical storm in the northern Gulf of Mexico to contribute to the wet and active pattern later next week.
