Forecast Discussion: Updated Friday, September 23, 2016 A cold upper level low pressure system will move through the area today bringing breezy conditions and a slight chance for an isolated shower, especially at higher elevations, but less wind than yesterday. Accordingly, continued low PM10 levels for most areas is expected today with a return to higher levels on Saturday as light winds and light morning stagnation help trap particulates close to the ground. The highest PM10 levels are anticipated to reach the middle of the moderate AQI category in Stanfield and especially Hidden Valley tomorrow. We can also expect a moderate PM10 AQI for the agricultural areas Monday and Tuesday as high pressure begins to build into the region and creates a tight pressure gradient with localized breezy to gusty easterly winds and associated blowing dust. PM2.5 levels should be in the good range on the AQI scale over the next several days with ozone also expected to remain in the good category. Forecaster: B. Farrell
