Forecast Discussion: Updated Wednesday, July 29, 2015 10 a.m. The anticipated dust arrived several hours earlier than expected last night as an early onset of blowing dust last night resulted in the Cowtown monitor exceeding the health standard for PM10. Additionally several other PM10 monitors had elevated levels of PM10 with San Tan Valley reaching the upper levels of the moderate AQI category. This was all due to storm development to the south and east last evening which created moderately strong outflow winds and blowing dust. Debris clouds from last night’s storm activity along with scattered light showers/sprinkles early today will eventually give way to some partial afternoon sunshine. The afternoon sunshine will help heat things up a bit though temperatures will remain below normal due to delayed sunshine from this morning’s cloud cover. This should limit the extent of storm development later today and tonight. An upper level disturbance moving through the area may help add an atmospheric ‘kicker’ that could make some of the storm cells pack a pretty good punch for winds and rain. Will keep the mention of blowing dust in today’s forecast along with the elevated PM10 AQI forecast numbers due to the outside chance for blowing dust. More storm chances on Thursday may bring some spotty blowing dust though the forecasted PM10 AQI levels are in the good to low AQI range due to the reduced likelihood of widespread blowing dust. High pressure will eventually build into the area this upcoming weekend and put a brief hold on the local monsoon activity. The ozone levels will remain in the good AQI category for the foreseeable future due to the periodic cloud cover, unfavorable wind directions and the gradual lowering of the sun angle in the sky that takes place this time of year.
