Forecast Discussion:

Low pressure will be the dominating weather pattern over the West and Southwest through this forecast period. As a result, high temperatures will be held in the 90s and breezy winds are expected most days. In particular, today (Friday) and Saturday will be the breeziest days.

For air quality, the most immediate topic of interest is the potential for blowing dust today. Hourly forecast PM10 (dust) levels have been raised accordingly and PM10 is forecast in the Moderate Air Quality Index (AQI) category. Then by Saturday, winds look to decrease, though they may be enough to still pick up some dust later in the afternoon/evening. PM10 is forecast in the Good AQI category.

By Sunday, winds are forecast to weaken more, thereby reducing the threat for wind-blown dust. Therefore, PM10 should become mostly locally driven. Ozone may begin to increase, however,

Then come Monday, the pattern may be such to allow ozone levels to increase into the low Moderate AQI category. PM10 should remain mostly locally driven. Tuesday looks to be similar, though stronger southerly winds could help to reduce ozone.
