Forecast Discussion:

Today, Arizona will be caught in between two competing weather patterns: low pressure over the Northwest and an expanding high pressure over the midsection of the U.S. This has resulted in a southerly flow over the Yuma area. Southerly winds in Yuma today and tomorrow will help to limit ozone levels and keep them in the Good Air Quality Index (AQI) category.

Then on Saturday, the high pressure will expand more westward over Arizona. This will result in winds becoming lighter in Yuma. Ozone levels are forecast to increase, but should still remain in the Good AQI category. Winds will be light on Sunday as well.

By Monday, southerly winds look to increase again and therefore help to reduce ozone levels. In all, ozone should remain in the Good AQI category through at least Monday.

No concerns are anticipated with PM10 (dust) during this period.
