Forecast Discussion: Current Conditions: Light snow continues this Tuesday afternoon as a slow moving area of low pressure moves off to our north. A secondary low pressure area will develop off the Virginia coast tonight and move northeastward Wednesday morning. This will act to continue the snow across the area, with total accumulations between 2 and 4 inches during the next 18 hours. *** Wednesday's forecast: Snow will end at mid morning Wednesday, then sunshine will return in the afternoon. Windy and cold with temperatures holding in the upper 20s. Strong mixing will bring lower levels of fine particulate by afternoon. Mostly clear and rather cold Wednesday night with low temperatures near 10 above. *** Extended forecast: A warmup is in store for later this week as high pressure settles near the Mid-Atlantic coast with winds turning into the southwest. Temperatures Thursday will reach the upper 30s, and be into the lower 40s by Friday. 50 degree temperatures cannot be ruled out by later in the weekend as a upper level ridge builds over the eastern part of the nation for the first time in awhile. The only downside is that air quality turns moderate again with mixing being limited along with higher humidity.---McAuliffe
