Forecast Discussion: You may have woken up to thunder early this morning, thanks to a line of thunderstorms that quickly passed northeastward through the Valley. Areas around Scottsdale and to the northeast received the most rainfall. Despite a break in the typical monsoon pattern, thunderstorms will continue to be possible over the higher terrain north of the Valley. As a result, there will be a potential for outflow winds to impact the Valley from the north today and tomorrow evening. Overall, chances for blowing dust will be minimal; PM-10 is forecast to remain in the Good AQI range. Ozone significantly improved around the Valley yesterday, with all but two monitors in the Good AQI range. As a small, atmospheric wave passes over Arizona today, ozone is expected to remain relatively low again today. However, ozone is forecast to begin increasing tomorrow behind the departing wave. There is some uncertainty in how high ozone will reach, but mid-Moderate AQI levels are a likely outcome through at least Thursday. Check back tomorrow for the latest. Until then, have a good day! –M.Graves Last Update: Tuesday, August 23, 2016, 9:53 AM
