Forecast Discussion:
An unseasonably strong low-pressure wave will drop into Arizona later today (Friday), resulting in another day of breezes out of the west and cooler than normal temperatures. Ozone is forecast in the Moderate AQI category, since winds can move ozone (and its ingredients) into Yuma from the west. Elevated PM10 (dust) levels will also be possible at times.
Then on Saturday, winds will shift to more out of the north. Ozone levels are forecast to improve. However, we still can't rule out pockets of dust because of the strength of the winds.
Then by Sunday and beyond, winds will become much lighter, especially Sunday. This will reduce the potential for dust. But, we'll have to watch ozone trends. Moderate ozone may be possible early next week.
Check back on Monday morning for the next Yuma Air Quality Forecast.
