Forecast Discussion: Current Conditions: At 2 p.m. EST this Tuesday afternoon, areas of snow continue across the region. The steady snow will end this evening, but there can still be another snow shower or two lingering overnight tonight. Temperatures overnight will settle back into the lower to middle 20s with good air quality. *** Wednesday's forecast: A pressure gradient between a storm departing off the New England coast and high pressure over the Plains will bring brisk and cold conditions to the area on Wednesday with a mostly cloudy sky and a snow shower here and there. Ample mixing will bring low levels of PM2.5. Afternoon temperatures only recovering to the upper 20s. Partly to mostly cloudy and cold Wednesday night with lows in the middle teens. *** Extended forecast: Temperatures will average below normal mid-February levels during the long range period, but will be especially so over the weekend, as a bitter blast of Arctic air comes southward behind a front expected to pass sometime Friday night. Periods of clouds and sunshine for the day Thursday with enough mixing present to maintain low levels of PM2.5. With an Arctic cold front approaching later Friday and Friday night, a few snow showers are possible. Any sunshine we get on Saturday will be ineffective as high temperatures may not get above the middle teens with wind chills below zero. Good air quality will continue until late in the weekend when winds will ease and stronger inversions develop Saturday night into Sunday. These factors will cause PM2.5 levels to increase by Sunday. Finally, there is the possibility of a storm system coming out of the southern U.S. which could produce more snow for us late Monday into Tuesday of next week.---McAuliffe
