Forecast Discussion: Current Conditions: At 2 p.m. EST this Friday afternoon, low pressure moving off to the north of the area is bringing a few snow showers our way. While fine particulate levels were inversion elevated this morning, increasing mixing will pull these concentrations down this afternoon. Mostly cloudy, brisk, and cold for tonight with a couple more snow showers, with lows remaining in the middle 20s. *** Saturday's forecast: Clouds for the most part and not as cold Saturday as a warm front passes off to the northeast. A decent level of mixing will promote low levels of fine particulate. Partly cloudy Saturday night with lows around 30 degrees. *** Sunday's forecast: Turning out mostly cloudy and milder Sunday, and a bit of rain is possible late in the day and at night, but with temperatures in the middle 40s. The influx of milder air on light southwesterly winds will bring fine particulate levels to the moderate range. *** Monday's forecast: Overcast skies will continue as the new workweek commences, but it will remain on the mild side with light winds. Once again, fine particulate may be moderate most of the day. *** Extended forecast: The next cold front passes through late Monday night or Tuesday morning, and rain showers and mild air will accompany it, with maxes early Tuesday possibly reaching 50 degrees. A brief shot of cold air then follows the front for Wednesday with moderating temperatures late in the week. Air quality should be good most of the extended period.---McAuliffe
