| 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. |
