Forecast Discussion: Updated Tuesday, April 21, 2015 10:25 a.m. The ozone levels yesterday reached the middle of the moderate AQI category, mainly due to the above normal temperatures, abundant sunshine and favorable wind directions which helped usher in ozone and its precursors from the Phoenix metro. Another warm day today along with favorable wind directions will help the ozone levels once again reach the moderate AQI category, though not expected to be quite as high as yesterday’s levels. The ozone levels will continue their decline on Wednesday as stronger afternoon winds from a less than favorable wind direction will help limit transport and local ozone formation. Over the next few days the typically elevated weekday dust causing activities will help morning PM10 levels rise but then afternoon atmospheric mixing will help lower the PM10 levels. The overall (24-hour average) PM10 levels the next day or so (excluding Cowtown) will be in the good to low range on the moderate AQI scale. A Pacific Low pressure system will move into the state on Thursday. Cooler temperatures with breezy to windy conditions will take over on Thursday along with the chance at some precipitation along with perhaps a thunderstorm. There will be some blowing dust in advance of any precipitation on Thursday as the wind gusts are expected to approach and perhaps surpass 30 mph! The PM10 forecast (excluding Cowtown) for Thursday at this point is in the middle of the moderate AQI category. However, the weather and air quality forecasts can and usually do change. Stay tuned.
