Forecast Discussion: FORECAST SUMMARY: Monday, August 25th, 2014 through Friday, August 29th, 2014 Ozone: 8-hour concentrations are expected to be Good to Moderate through Tuesday then mostly Good through the remaining forecast period… PM-2.5: 24-hour Fine Particulate concentrations are expected to be generally Moderate through Tuesday then mostly Good through the remaining forecast period… FORECAST DISCUSSION: Hot, humid weather will persist into Tuesday in advance of a cold front projected to pass through the state during the day Tuesday. Air Quality concentrations were Good for ozone, through the weekend, with mostly Moderates concentrations for PM-2.5. I expect only a modest creep in those concentrations through Tuesday with increasing cloud cover and shower potential. Once the cold front passes through the state by late Tuesday, cooler dryer air will follow providing comfort relief and improved Air Quality. That reprieve last for a couple of days as humidity begins to surge back into the region Thursday night. The long range model forecasts have the chance for precipitation and warmer temperatures through the weekend. As such, the regional forecasters will have another call on Friday to discuss potential Air Quality issues for the holiday weekend. EXTENDED FORECAST: Warm weather will return to the region during the holiday weekend. Forecast updated by Jim Haywood: Monday, August 25th, 2014 Next forecast update: Friday, August 29th, 2014
