Forecast Discussion: FORECAST SUMMARY: Friday, September 4th, 2015 through Saturday, September 5th, 2015 Ozone: 8-hour Ozone is expected to range from Good to Moderate; with isolated USG possible Saturday. PM-2.5: 24-hour Fine Particulate concentrations will be in the Good to Moderate range. FORECAST DISCUSSION: An upper level system lingering over the state Friday will keep more in the way of clouds overhead. This will help keep ozone levels from reaching higher than low Moderate and several locations will have 8-hrlys in the Good range. Precipitation from later Thursday improved fine particulate levels and readings will range from middle Good to low Moderate. On Saturday, the upper level system moves further from the state with surface and upper level riding becoming more prevalent. Forecast models do keep clouds over much of the state through middle afternoon. The wind flow is rather light but does become south to southwest during the day. My thoughts on the forecast are that breaks in the cloud cover during the afternoon hours will allow ozone to climb into the Moderate range in the southern half of the state. There is a small chance a monitor or two along the west Michigan lakeshore, or just downwind of the Detroit area, could hit USG Saturday but my confidence in that isn’t strong enough to issue an Action Day. Fine particulate will begin increasing again toward the Moderate range. By Sunday, the position of the surface and upper level ridges will produce a better southwest wind flow. Plenty of sunshine is expected and the warm, humid conditions remain in place. Sunday will be our best chance for seeing high pollution levels; therefore, we will be having a regional forecast call Saturday morning to determine if an Action Day will be necessary. EXTENDED FORECAST: Extended models have been consistent in showing a frontal boundary sinking in Monday bringing with it clouds and precipitation. If this forecast pans out, ozone will improve Monday; however, fine particulate will remain Moderate.
