Forecast Discussion: Thunderstorms in and around the Yuma area throughout yesterday morning resulted in blowing dust and haziness, causing visibilities to drop down to two miles or less. Unfortunately, PM-10 concentrations soared dramatically during this period, enough to allow the daily AQI average to reach Health Watch criteria, despite recovering to healthy levels after noon. So far this morning, PM-10 concentrations have been elevated thanks to gusts and decent winds associated with passing storm cells (though not to the extent as seen yesterday). Chances for thunderstorms and brief showers in/around the Yuma area will remain active today. Ultimately, today’s final 24-hr average will likely turn out higher than forecast. Looking ahead, it appears we will finally have a break from the monsoon pattern as mid-level winds turn more southerly. This means storm activity will diminish across southeast Arizona. Thus, no blowing dust issues are foreseen in Yuma this afternoon through at least Friday; PM-10 is expected to remain at most in the middle Good range. Regarding ozone, the National Weather Service's model is suggesting the possibility of some import from Southern California on Thursday as low-level winds shift to more westerly. Thus, there is a potential for elevated ozone concentrations Thursday and Friday. Check back tomorrow for the next air quality forecast. Until then, have a good day! -M.Graves
