Forecast Discussion: FORECAST SUMMARY: Monday, April 21st, 2014 through Monday, April 28th, 2014 Ozone: 8-hour concentrations are expected to be Good through the forecast period… PM-2.5: 24-hour Fine Particulate concentrations are expected to be Good to Low Moderate through the forecast period… FORECAST DISCUSSION: The previous week provided mostly Good Air Quality throughout the region with only a few scattered Low Moderates for fine particulates. This week should be mostly the same. A cold front is slowly moving through the state during Monday and will push out the first 70 degree days we have seen in about six months. Shifting winds, behind the front, will usher in cooler temperatures and Good Air Quality for mid-week. Brisk southerly winds will briefly visit the region on Thursday before the next cold front passage Thursday night. The southern winds could provide a slight creep in fine particulates on Thursday. But the time period will be short and the winds turbulent, thus no serious concerns. EXTENDED FORECAST: Cooler air will persist through the weekend with Good Air Quality.
