Forecast Discussion: Updated Thursday, May 28, 2015 10 a.m. **OZONE HIGH POLLUTION ADVISORY FRIDAY, MAY 29, 2015** Well it didn’t take long for the PM10 levels to rise enough and make it into the moderate AQI category. Three PM10 monitoring locations (Cowtown, Eleven Mile Corner and Stanfield) made it into the low moderate AQI category yesterday due to some elevated dust causing activities during the morning hours. PM10 wasn’t the only criteria air pollutant which made it into the moderate AQI category yesterday, Ozone joined in as well. The Pinal Air Park and Apache Junction monitoring locations each reached moderate for ozone. The main reason was the light winds, increased sunshine and temperatures yesterday afternoon. High pressure will be in control of the region over the next several days. The most noticeable aspect will be the hot temperatures with afternoon highs breaking the century mark. There will be light winds and abundant sunshine which will also help in the formation of ozone. The levels of ozone are expected to exceed the health based standards on Friday and as such an ozone High Pollution Advisory (HPA) has been issued for Friday. The ozone HPA is likely to be extended to Saturday as ozone levels are expected to be slightly higher on Saturday. Anyone with respiratory and/or heart ailments should limit outdoor activities during the afternoon and early evening hours when ozone levels are typically the highest. Less favorable wind directions along with typically lower emissions on Sunday will help ozone levels drop a bit. PM10 level meanwhile will reach low moderate in a few locations on Friday and Saturday due to the stagnant conditions expected during the early morning and evening hours. The stagnant conditions will help trap the particulates associated with dust causing activities close to the ground and thus result in elevated PM10 concentrations. Forecaster – S. DiBiase
