...Snow showers to continue overnight and early Friday morning...
A surge of colder Arctic air into the region will provide progressively colder temperatures and upslope westerly winds overnight and early Friday morning. This is resulting in intermittent snow showers this evening...and this is expected to continue overnight and into the early morning hours Friday.
Snow accumulations will be most common at higher elevations and on west facing slopes of the mountains. Reported snow accumulations so far this evening range from trace and dusting amounts across Bath...Smyth...and Grayson counties in Virginia...Greenbrier...Monroe...Summers...and Mercer counties in West Virginia...to around 1/2 inch in eastern Tazewell County Virginia...where roads are becoming snow covered...to more widespread 1 to 2 inch amounts across much of Ashe and Watauga counties in northwest North Carolina.
With colder air steadily moving into the region overnight...untreated roads and surfaces will likely become snow covered...slick...and hazardous.
At this time...total nighttime snow accumulations are expected to remain less than 2 inches...thus an advisory does not appear warranted at this time. Nonetheless...additional caution should be exercised if traveling tonight or early Friday morning in these areas.
