Forecast Discussion: Updated Monday, September 26, 2016 A developing low pressure system south of the border and its tight pressure gradient has brought thick overcast skies and breezy conditions today. There’s the chance for sprinkles and perhaps a scattered shower today. The biggest impact locally and air quality wise will be the breezy to gusty easterly winds. There are plenty of ground surfaces being disturbed through various activities which will provide an ample supply of particulates. So areas of blowing dust today will result in elevated PM10 levels with some of the higher locations approaching the health standard. Another breezy day on Tuesday with the added possibility for some thunderstorm activity and associated outflow winds. At this point have the highest forecasted PM10 levels in the mid/upper range of the moderate AQI category on Tuesday. Stay tuned and check back on Tuesday for an updated air quality forecast. In the meantime, PM2.5 levels in and around the western areas will be in the low/mid moderate range today and again Tuesday. Ozone will be in the good AQI category. Forecaster: S. DiBiase
