Forecast Discussion: Ozone transport got an early jump yesterday allowing concentrations to soar from a 40 AQI on Monday to an 84 AQI yesterday! The Yuma weather balloon launched earlier this morning indicated a west-northwesterly wind pattern persisting near the surface up to about 6,000 feet in altitude. Therefore, import of ozone precursors continues and similar peak 8-hr average ozone values in the upper Moderate range are anticipated today. The weather pattern is expected to change abruptly on Thursday to a more typical monsoonal setup. Ozone will fall back into the Good AQI at this time. Deeper moisture and greater instability look to follow a moisture surge coming up from the Gulf of California tomorrow morning. Better regional thunderstorm coverage is expected to last through the weekend. High resolution models show the Yuma area could be impacted by outflows from distant thunderstorms from the east early Friday morning and again later that evening. Measurable rain appears unlikely for now, but gusty winds carrying dust can raise PM-10 levels into the Moderate category. Check back tomorrow for the latest. Until then, have a good day! -J.Malloy
