Forecast Discussion:

The low pressure system is now moving off to the east and is being replaced by a large ridge. This ridge will bring sunny skies, warmer temperatures, and lighter winds. This will allow ozone levels to trend up into the mid/upper Moderate AQI range to close out the week. Additionally, it is looking likely that we will see our first triple digit temperature of the year before the week is out. By Saturday and Sunday, the ridge is forecast to weaken a little and shift to the east of Yuma. This will cause more southerly winds, which should help lower ozone a bit due to less influence from California.

No PM10 issues are expected in the forecast period. With the ridge influencing the region over the next several days, we don't anticipate any winds capable of kicking up dust. Therefore, PM10 is forecast to remain in the Good AQI range for the next several days.
