Forecast Discussion: There did end up being a little dust activity yesterday which barely tipped PM-10 into the Moderates. As for today, we continue to have breezy easterly winds due to the cut-off low located to the south. In addition to winds, we also currently have showers and thunderstorm to the southeast. Some of this activity may push into the Valley today but most of it is expected to stay to the south. The main air quality threat today will be dust associated with thunderstorm outflows. Blowing dust is possible but stable soils from recent rains and the brief nature of any outflows should prevent PM-10 levels from getting too high. We forecast potential low-Moderate levels of PM-10 due to brief blowing dust this afternoon. Weather conditions should begin calming down tomorrow and Thursday. This will allow particulates to drop back down into the mid-Good range, while ozone increases back into the Moderates. One potential exception is if Tropical Storm Roslyn advects more moisture into the area than anticipated, we may see active weather last longer into the week. Of course, we will continue monitor the weather and air quality for any changes. Check back tomorrow for the latest. Until then, have a good day! –R.Nicoll Last Update: Tuesday, September 27, 2016, 8:47 AM
