Synopsis & Discussion
Forecaster: -M. Graves
High temperatures in the low-mid 60s F will hold on through at least Saturday as a cooler air mass hangs over the region. By Sunday, highs will then start approaching 70 degrees again as high pressure develops over the region. Monday is forecast to be the warmest day of this forecast period, with a high in the low 70s. Cooler air looks to return on Tuesday.

Air quality-wise, the main talking point is the potential for blowing dust tomorrow afternoon due to breezy winds out of the west/west-northwest. However, the system responsible for these winds is not near as strong as the system that brought windy and gusty conditions to Yuma this past Monday. PM-10 (dust) levels will likely be highest at the onset of the breezy winds, but should gradually decrease as the day progresses. PM-10 is forecast in the Moderate Air Quality Index (AQI) category tomorrow.

Through the rest of this forecast period, PM-10 is forecast in the Good AQI category. No issues with ozone are expected either.

Check back tomorrow for the next Yuma air quality forecast.
