Forecast Discussion: FORECAST SUMMARY: Friday, August 26th, 2016 through Monday, August 29th, 2016 Ozone: 8-hour Ozone values will range mostly Good; with only a few Moderates possible. PM-2.5: 24-hour Fine Particulate concentrations will range between Good and low Moderate. FORECAST DISCUSSION: High pressure in control Friday will produce a nice, comfortable day with warm temperatures and lower humidity’s. A storm system moves into the area Saturday bringing with it chances for rain and storms through early Sunday. The cold front associated with this system passes through Sunday with high pressure moving in which dries conditions out for the beginning of the week. Air quality levels have been mostly Good this week. Sunshine and warmer temperatures may cause a monitor or two to reach Moderate for ozone Friday, but for the most part readings will remain Good. Clouds and chances for rain Saturday, into Sunday will keep ozone Good through the weekend. On Monday, high pressure moves through with a southerly wind flow developing during the day. This may cause a few locations to once again reach Moderate for ozone. With increased moisture during the weekend, fine particulate may increase into the Moderate range Saturday and Sunday; generally Good fine particulate is expected for Monday. EXTENDED FORECAST: Precipitation chances move back in the forecast late Monday, into Tuesday. This keeps ozone Good, while a few Moderates for fine particulate are possible.
