Forecast Discussion: Updated Monday, May 25, 2015 10 a.m. After a quiet weekend weather and air quality wise, this Memorial holiday week will follow suit in the weather department and not so much in the air quality department, at least not in regards to ozone. The PM10 levels will remain relatively low due to the rain received a little over a week ago. Troughiness the next day or two will usher in high clouds from time to time which will inhibit ozone formation. High pressure will build in as the work week progresses and help raise the afternoon high temperatures into more seasonal ranges (90s to low 100s). The hotter temperatures along with abundant sunshine later this week and favorable transport wind directions will help the ozone levels rise well into the moderate AQI category. Thursday’s AQI forecast for ozone is in the middle of the moderate category. Stay tuned as the forecast may be increased dependent on the forecasted transport winds and high temperatures. In the meantime, enjoy the Memorial Day holiday. Forecaster – S. DiBiase
