Forecast Discussion:

Particulate matter (PM) will continue to be the main pollutant of interest for this Yuma air quality forecast. Ozone will easily remain in the Good Air Quality Index (AQI) category given the time of year (there's not enough sunlight for ground-level ozone to form). However, PM will vary more because of local activity and some breezy winds in the near-term forecast.

On any given day, when weather conditions are stagnant--particularly in the mornings or evenings--both PM10 (dust) and PM2.5 (smoke) will have the potential to be locally elevated in Yuma. Hourly forecast graphs reflect these daily trends. Moreover, substantial jumps in PM, like this morning, may also be possible, but they're highly dependent on local activity.

Furthermore, breezy winds are forecast to enter the picture on Sunday and Tuesday as a couple of low pressure waves affect the region. As a result, we can't rule out the possibility of pockets of dust. Therefore, PM10 levels have been increased. But right now, winds are looking to be stronger on Tuesday, so PM10 may reach the Moderate AQI category.
