Forecast Discussion: Updated Monday, July 28, 2014 10:45 a.m. A much needed break in the local Monsoon storm activity for this work week. After the large Haboob and associated widespread PM10 exceedances on Friday, another outflow dust event in north central (i.e. San Tan Valley) Pinal County on Saturday night and predawn dust on Sunday, the local area could use a break from poor air quality. So, it’s good news that the remainder of the work week will be much quieter from an air quality perspective. The Monsoon high pressure will move into a less favorable location (for local storm activity) this week and bring drier air into the local area. The PM10 levels will be mainly in the good AQI category with only Stanfield and Cowtown reaching the moderate category over the next few days. The ozone levels reached the low moderate AQI category at all three monitoring locations on Sunday. That was the first time since June 9th. So far this morning the Casa Grande ozone levels are slightly higher than yesterday at this time, so today’s original AQI forecast for good levels of ozone in Casa Grande has been increased into the moderate AQI category. More moderate ozone levels are expected for Tuesday and Wednesday as light winds and abundant sunshine help ozone formation. Check back on Tuesday for an updated air quality forecast. Forecaster – S.
