Forecast Discussion: FORECAST SUMMARY: Thursday, September 3rd, 2015 through Friday, September 4th, 2015 Ozone: 8-hour Ozone is expected to range from Good to Moderate. PM-2.5: 24-hour Fine Particulate concentrations will also be in the Good to Moderate range. FORECAST DISCUSSION: Warm temperatures and high humidity levels will persist as we move into the weekend. An upper level wave/boundary over the region will trigger showers and storms Thursday, into Friday. There is a possibility precipitation could linger Saturday as the boundary positions itself just south of the state; however, it would be more scattered in nature. Winds are rather light the next two days but the flow does have more of an east/southeasterly direction. With all these factors in place, high ozone levels are not much of a concern through Friday. 8-hrly readings should remain mostly Good in northern/central portions of the state with areas further south possibly hitting the Moderate range. With a boundary nearby, increased humidity, and lighter winds I’m expecting fine particulate to remain Moderate across central and southern portions of the state with Good levels further north. On Saturday, the wind flow changes to more of a southerly direction as surface and upper level ridging build over the region. There is uncertainty on if precipitation will linger across parts of the state. At this point, there seems to be a small chance for precipitation but clouds will be less prevalent than on Thursday and Friday. I plan on forecasting Moderate ozone and fine particulate across the central and southern portions of the state. However, if forecast models change to where rain chances are no longer expected, then ozone levels may start increasing. We have another regional forecast call Friday morning to evaluate the current weather models. By Sunday, both surface and upper level winds change to a stronger southwesterly direction. Warm temperatures will continue to be in place, along with increased humidity. This looks to be our next conducive day for increased ozone and we will be evaluating conditions through the weekend. EXTENDED FORECAST: Extended models still show the warm/muggy forecast continuing until early next week when a stronger cold front possibly moves in. For the coming holiday weekend, chances for increased pollution will continue...
