Forecast Discussion: Current conditions: Mostly sunny conditions this Thursday afternoon with high pressure overhead. Fine particulate levels have risen some, but remain in the upper good range. Clouds will increase and thicken later on. *** Friday's forecast: Friday turns out cloudy with a bit of rain or drizzle. Light winds and precipitation may mean fine particulate moves into the lower moderate range. Periods of rain are likely Friday night as temperatures slowly rise. *** Extended forecast: A storm moving up the east coast will bring rain, some heavy, into late Saturday afternoon. Increasing rainfall intensity will bring PM levels down into the good range. Windy and chilly Sunday with sunshine returning. The next storm will affect us with precipitation later Monday into Tuesday, and if the storm tracks more to our southeast, some of the precipitation might be in frozen form. Overall air quality should remain good Sunday into Monday.---McAuliffe
