Forecast Discussion: FORECAST SUMMARY: Monday, September 15th, 2014 through Monday, September 22nd, 2014 Ozone: 8-hour concentrations are expected to be mostly Good through the forecast period… PM-2.5: 24-hour Fine Particulate concentrations are expected to be generally Good to Low Moderate through the forecast period… FORECAST DISCUSSION: A clean air pattern is expected throughout the forecast period providing Good Air Quality to the region. The passage of a Monday cold front will provide clouds and showers during the first day of the work week. High pressure will build in during Tuesday and generally dominate our skies during the remainder of the work week. Despite mostly sunny skies, cooler temperatures and favorable wind directions will keep any ozone buildup in check. The next chance of warming will come late in the work week and early into the weekend. Winds will turn more southerly in advance of the next system expected late Saturday and early Sunday. However, winds will be quite brisk and the southerly component will be relatively short-lived. Therefore I do not expect any degradation in Air Quality. EXTENDED FORECAST: Cool, clean air should persist into the next work week providing Good Air Quality.
