Forecast Discussion: Current Conditions: Low pressure continues to move off the east coast this Wednesday afternoon, and high pressure is building in it's place to our south. Stronger northwesterly mixing will bring good air quality to the area this afternoon and evening. Tonight will be mostly clear and rather cold with lows in the single digits in the coldest parts of the area, and a weak temperature inversion will bring moderate PM2.5 levels late tonight. *** Thursday's forecast: Breezy Thursday with sunshine most of the time, and the afternoon will not be as cold with temperatures recovering to the lower to middle 30s. Ample mixing will bring overall fine particulate averages for the day down to the good range. Mostly clear with light winds Thursday night, and a stronger inversion brings fine particulate into the moderate range. *** Extended forecast: Tranquil weather will prevail Friday into the weekend with temperatures climbing above normal as the flow shifts into the southwest. In fact, high temperatures by Sunday may reach close to 50 degrees. Lighter winds and less mixing will mean fine particulate attains the moderate range most of the time in the Friday to Sunday period. The next frontal system reaches us later Monday or Monday night, but with precipitation in the form of rain.---McAuliffe
