Forecast Discussion: Updated Monday, July 27, 2015 10 a.m. After several days of relatively quiet weather the atmospheric conditions are changing and will become more active this week. A trough located to our south and east this morning will retrograde and move towards the state over the next day or two. The changing atmospheric dynamics will mean better chances at storm development over areas to our south and east, especially on Wednesday. The chances for strong outflow winds creating areas of blowing dust increase on Wednesday, therefore the PM10 AQI forecast for Wednesday is in mid/upper level of the moderate AQI category. The forecast is just shy of the PM10 Health Watch category. Stay tuned and check back on Tuesday as the PM10 AQI forecast for Wednesday may change and go into the PM10 Health Watch or higher (PM10 High Pollution Advisory). More chances for storm development again on Thursday along with outflow winds, though any precipitation from the storms on Wednesday should keep the PM10 levels in check on Thursday. The ozone levels will remain in the good AQI category today and reach low moderate in northern Pinal County on Tuesday due to favorable winds. The ozone levels will drop on Wednesday as the monsoon activity picks up with more of the same on Thursday. Forecaster – S. DiBiase
