Forecast Discussion: Current conditions: After a mild morning, a cold front has swept through the area and brought in chillier air this Tuesday afternoon. Strong mixing from the west and northwest has resulted in lowered levels in fine particulate. Partly to mostly cloudy overnight with PM increasing, but remaining within the good range. *** Wednesday's forecast: An area of high pressure building into the Tennessee valley on Wednesday will bring a little afternoon sunshine as temperatures move close to 40 degrees. Fine particulate matter will remain at the top end of the good range with lighter winds and dry air in place. Turning mostly cloudy Wednesday night with a bit of snow developing. *** Extended forecast: A cold front moving across the area on Thursday brings rain and snow showers early, with increasing winds by afternoon. Particulate matter concentrations will quickly drop to the good range by afternoon. Good air quality continues on Friday with plenty of clouds along with a couple of snow showers. High temperatures will only go just past 30 degrees. Our progressive weather pattern will continue as we move on into 2017 with another front bringing snow showers early New Year's Day, then a wave of low pressure along a stalled front across the Tennessee valley brings sleet turning to rain Monday. PM2.5 levels during this period will range from upper good to lower moderate.---McAuliffe
