Forecast Discussion: FORECAST SUMMARY: Thursday, July 24th, 2014 through Wednesday, July 30th, 2014 Ozone: 8-hour concentrations are expected to be mostly Good through forecast period… PM-2.5: 24-hour Fine Particulate concentrations are expected to be mostly Good to Low Moderate through Saturday then Good for the remainder of the forecast period… FORECAST DISCUSSION: During our Action Days of the previous Monday and Tuesday, we saw concentrations in the low 70’s ppb range but none exceeding the USG threshold. So kudos to those who practiced Action Day policies as that might have made the difference! We will be going into an extended period of Good Air Quality over the next week. The area is currently under a cell of high pressure as we head into the end of the work week. As that high pressure slips eastward on Friday, the area will come a light, southerly wind pattern. A warm front will move northward and impact the state on Saturday. Clouds and shower activity will keep ozone levels low but fine particulates could creep into the Low Moderate range. A cold front will follow on Sunday cleaning out any residual PM-2.5. The majority of next week will be under a cool, dry, northwest wind pattern. No Air Quality issues are expected. EXTENDED FORECAST: Cooler weather and Good Air Quality should last through next week… Forecast updated by Jim Haywood: Thursday, July 24th, 2014 Next forecast update: Wednesday, July 30th, 2014
