Forecast Discussion: A weak, upper-level atmospheric wave will depart Arizona today, resulting in a drier, northwesterly flow over the state. Storm activity will be limited to the north and east of the Valley this afternoon. However, high resolution models do agree that there is a potential for relatively strong storm outflows to impact the Valley from the north this evening. Weather will remain generally quiet through Thursday into Friday. Small storm chances do exist for Friday though, as a more monsoon-like flow pattern is expected to resume. Air quality-wise, no significant PM-10 (dust) issues are expected through at least Friday. Therefore, PM-10 is forecast to remain in the Good AQI range. Near-surface winds should help to keep ozone in check today. Slight increases in ozone are expected tomorrow as winds become lighter. Highest ozone levels are expected to be reached in eastern portions of the Valley today and tomorrow. For now, ozone is forecast to remain in the middle Moderate AQI range. Check back tomorrow for the latest. Until then, have a good day! –M.Graves Last Update: Wednesday, August 24, 2016, 9:20 AM
