Forecast Discussion: Updated Thursday, October 19, 2017 The winds in Hidden Valley early today have been favorable for transport of local dust to the monitor. The PM10 hourly averages from 4-8 a.m. today have ranged from 226 ug/m3 all the way up to 1,554 ug/m3! It’s not out of the realm of possibility that Hidden Valley may exceed the health standard today. If so, it will be the 28th PM10 exceedance day of 2017 at Hidden Valley. Speaking of exceedances, Hidden Valley exceeded the health standard for the PM2.5 24-hour average yesterday, the 8th such exceedance of 2017. The main culprit appears to have been local agricultural burning. Thankfully so far today the Hidden Valley PM2.5 levels are lower than they were yesterday at this time. A weak weather system is currently moving through the area today. Some sprinkles have been falling early today and there’s a chance for shower activity over the high country of eastern Pinal County. A trough will skirt by to the north on Friday and bring breezy conditions. Some blowing dust is expected and a slight bump up in PM10 levels in most places (Excluding Hidden Valley). Overall the PM10 levels are going to be in the upper good to mid-moderate range on the AQI scale. Hidden Valley is forecasted to be in the mid to upper range of the moderate AQI category Friday and Saturday. Stay up to date with current air pollution levels by checking out the near real-time PM10, PM2.5 and ozone levels online at http://www.pinalcountyaz.gov/AirQuality/Pages/AirQualityReport.aspx. The PM2.5 levels will follow behind the PM10 levels and be in the range of upper good to upper moderate on the AQI scale. The ozone levels are expected to be in the upper good range on the AQI scale for the remainder of the work week. Forecaster: Forecaster: S. DiBiase
