Forecast Discussion: Current conditions: Cold and gusty northwesterly winds are making winter's presence felt across the area this Wednesday afternoon, and the strong horizontal mixing has led to low values of fine particulate. In spite of sunshine, temperatures have struggled to get to the 30 degree mark with the wind making it feel like it is in the teens. Tonight, an area of low pressure coming out of the Ohio valley will bring snow to the region, with anywhere from a coating across the south and 2 inches across northern areas. *** Thursday's forecast: Brisk and continued cold Thursday with sunshine returning. Good horizontal and vertical mixing will promote good air quality, but high temperatures only reaching the lower to middle 30s. Mainly clear and cold Thursday night with lows in the middle teens, and a developing inversion will push PM numbers higher into moderate levels late. *** Extended forecast: A weak area of low pressure passing north of us will bring more cloudiness Friday, and a snow shower or two late Friday into Friday night. Lighter winds will cause fine particulate to be higher over Thursday, but afternoon mixing should be enough to keep the overall daily average in the upper good range. Clouds and some sunshine, brisk and chilly Saturday with plenty of mixing bringing good air quality. Temperatures will moderate some Sunday, with morning sunshine giving way to afternoon cloudiness and highs recovering close to 40 degrees. Light south winds will bring fine particulate levels back to the moderate range. The next cold front affects the area early next week with the chance for rain as it approaches, with another shot of cold air to follow for the mid week period.---McAuliffe
