Forecast Discussion: Current conditions: High pressure is producing more spectacular weather this Thursday afternoon with sunny skies. Ozone levels have moved into the lower moderate range in spots, while fine particulate levels remain low. Clear and seasonably cool tonight with low temperatures falling back into the lower 50s. *** Friday's forecast: Periods of clouds and sunshine for the day Friday, and with light southwest winds producing little mixing, fine particulate and ozone may go to the moderate range. *** Extended forecast: A weak warm front in the vicinity may bring a shower Saturday, otherwise skies will be partly sunny. Ozone will move back into the good range, while fine particulate remains moderate. Increasing winds out ahead of the next cold front will keep ozone and PM in the good range Sunday, then the front moves through Sunday night or early Monday morning with some showers. Temperatures early next week will return to normal late September levels with good air quality continuing.---McAuliffe
