Forecast Discussion: Current conditions: Seasonably warm conditions prevail across the area this Friday afternoon with ozone and fine particulate levels ranging from the upper good to lower moderate range. Rather warm and humid conditions over the weekend will result in an increase in pollutants across the area as a light southwesterly flow persists. For tonight, expect warm and muggy conditions as temperatures fall back into the middle 60s. *** Saturday's forecast: Periods of clouds and sunshine, warm, and humid Saturday with a better chance for afternoon and evening thunderstorms. The afternoon convection should hold ozone levels to the upper good range, but fine particulate may still go moderate due to light southwest winds and increasing humidity. *** Sunday's forecast: Partly sunny skies Sunday with elevated humidity levels. Only isolated late day thunderstorms are possible, with ozone and fine particulate mainly in the lower moderate range. *** Monday's forecast: With higher weekday emissions Monday, moderate levels of PM2.5 and ozone are likely, with the highest PM in the morning hours, but an afternoon ozone peak as temperatures climb into the upper 80s in many locations. *** Extended forecast: The weather picture turns more unsettled Tuesday with an increasing chance for showers and thunderstorms. By Wednesday, a cold front will be moving through, leading a cool down later on in the week. Air quality will remain moderate on Tuesday, then a return to good levels is possible Wednesday into Thursday.---McAuliffe
