A weak boundary will settle slowly through Oklahoma with isolated thunderstorms over the next few day.  Light Saharan dust will maintain moderate fine particulate matter ahead of the boundary.  After the boundary passes, drier continental air aloft and perhaps a small inversion will foster ozone formation early next week.  Air quality may worsen through next week, at least until the boundary lifts northward and a maritime air mass returns, but much uncertainty exists in that forecast.  Thicker Saharan dust but low ozone will accompany the maritime air mass late next week.  Summer heat and isolated rain showers will persist.
