Forecast Discussion:

A large low pressure wave sits over the Pacific Ocean this morning (Friday), poised to progress eastward into the continental U.S. Over the next several days, this wave will, in fact, slowly make its way into the West Coast, strengthening as it does so. This new pattern will ultimately push the monsoonal high pressure off to the southeastern U.S., constraining thunderstorm activity to the eastern third of Arizona by the weekend. For Yuma, chances for thunderstorms--or their winds--are not anticipated for a while.

However, Yuma will not be without its weather. The developing low pressure pattern over the region will be the impetus for mountain-driven winds (i.e. from the mountains east of San Diego) to move into Yuma during the next few evenings. Given the dryness to the west of Yuma, blowing dust may be possible. Hourly PM10 (dust) levels have thus been raised to reflect this.

Lastly, today through Sunday, ozone looks to have the potential to be elevated because of light winds out of the west at times. Therefore, ozone is forecast in the Moderate Air Quality Index category each day. Then by Monday, more southerly flow is forecast to help reduce ozone.

Check back on Tuesday for the next air quality forecast.
