Forecast Discussion: Current Conditions: At 2 p.m. EST this Tuesday afternoon, northwesterly winds continue to drive colder air into the area, with periods of snow accompanying the chill. Increasing mixing is also lowering fine particulate into the good range this afternoon. Snow showers tonight will accompany a frigid wind, bringing wind chills down close to zero as actual temperatures fall to the middle teens. *** Wednesday's forecast: Any morning sun Wednesday will give way to clouds in the afternoon, and a bit of snow can even occur by evening as another low pressure area moves out of the Ohio valley. Ample mixing will mean low PM2.5 concentrations. Snow will continue Wednesday night, and there can also be a couple of inches of accumulation. *** Extended forecast: Snow ending early Thursday will yield to a little afternoon sunshine with high pressure building in from the west. Friday will bring considerable cloudiness, and an area of low pressure passing well to the north will spell snow showers Friday night into Saturday morning. Moderation in temperatures is likely over the weekend as the surface and upper level flow turn more west to southwesterly. Temperatures by Sunday may reach the 40s once again, before another low coming out of the Tennessee valley moves in with a mixed precipitation event Sunday night and Monday. Air quality in the long range period mainly in the good range, with the best chance for moderate coming Friday.---McAuliffe
