Forecast Discussion: Current conditions: Very mild air continues to stream into the area on light south winds this Monday afternoon, and the lack of mixing is keeping PM2.5 concentrations moderate. Rain and a thunderstorm will affect the area along and out ahead of a cold front tonight. Temperatures will fall back to the middle 40s towards morning. *** Tuesday's forecast: Turning windy behind the cold front Tuesday with rain showers left over. Temperatures will start out in the middle 40s, then fall some late in the afternoon. Plenty of mixing will bring air quality to improved levels over Monday. Mostly cloudy with a snow shower or two Tuesday night as lows dip to the upper 20s. *** Extended forecast: High pressure will slowly build over the area during the middle of this week, then be moving off to the east by week's end. Temperatures will drop to near normal for the middle of this week, then milder air moves back in late week with winds turning more south-southwesterly. Air quality will be good Wednesday with plenty of mixing and dry air being present, but then PM2.5 concentrations may increase by later this week due to both warm air advection, light winds, and stronger temperature inversions.---McAuliffe
