The intensity of snow has continued to gradually increase this evening. Snowfall rates should at least persist at current levels if not increase. Rates of between 1-3" per hour are likely overnight. By morning (over the next twelve hours), most places in the metro region should pick up another 10-12 inches of snow, with locally higher amounts. Another 4-8" is possible during the day Saturday. We continue to expect total accumulations of 16-26". Temperatures are holding right around freezing which is making this a heavy, wet snow. Unfortunately, that may increase the risk of power outages as the night wears on (although temperatures should start dropping off some more after midnight), especially with winds increasing.

So far, most areas have picked up 3-6", with locally heavier amounts to the northwest and southwest of the immediate metro area. From Fredericksburg to Charlottesville, Va., there have been reports of sleet. Some sleet may advance northward and mix with snow in southern and eastern suburbs through around midnight, but the predominant precipitation type for the most of the metro region should be snow.
