Forecast Discussion: FORECAST SUMMARY: Wednesday, July 30th, 2014 through Monday, August 4th, 2014 Ozone: 8-hour concentrations are expected to mostly Good with scattered Moderates possible early next week. PM-2.5: 24-hour Fine Particulate concentrations will range between middle Good and low Moderate. FORECAST DISCUSSION: Weather conditions the next couple of days will remain consistent with cooler temperatures and scattered, mostly late afternoon/early evening, showers/storms. As we progress into the weekend temperatures will experience a slow climb with more seasonable highs early next week. The threat for mostly afternoon/early evening storms will continue through Saturday. Air pollution levels have been Good this week for both ozone and fine particulate. With surface and upper level temperatures both remaining on the cool-side, ozone levels will remain Good through Saturday. Surface and upper level winds have a northerly component; however, the flow is not strong. Fine particulate may increase into the low Moderate range, especially in southeastern areas. EXTENDED FORECAST: The surface wind flow turns more southwesterly by Sunday/Monday and the upper level system producing clouds and scattered precipitation this week will finally move to the east. With warmer temperatures and a more conducive wind flow, ozone may climb into the Moderate range in a few locations early next week. Fine particulate early next week could also reach the Moderate range. Forecast updated by Stephanie Hengesbach: Wednesday, July 30th, 2014 Next forecast update: Monday, August 4th, 2014
