Forecast Discussion: FORECAST SUMMARY: Monday, September 26th, 2016 through Friday, September 30th, 2016 Ozone: 8-hour Ozone values are expected to be Good. PM-2.5: 24-hour Fine Particulate concentrations will also be in the Good range. FORECAST DISCUSSION: With the end of September being Friday, this forecast will officially end the 2016 ozone forecasting season. The season will come to a close with Good ozone levels thanks to a cold front passing Monday, and then an upper level low positioning itself over the region for the rest of the week. Accompanying the upper low will be northerly winds, cooler temperatures and scattered rain showers. These conditions will linger through Friday. As with ozone, the anticipated weather conditions will keep fine particulate in the Good range. EXTENDED FORECAST: At this time it’s a little uncertain if the upper level low will keep scattered showers in the forecast during the upcoming weekend. The way it looks now, precipitation may linger Saturday and Sunday with drying conditions Monday. Good fine particulate is expected this weekend but readings may increase towards the Moderate range Monday.
