February 27-28th, 2008 Northwest Flow Snowfall


A strong cold front moved through the area late in the afternoon on the 26th. Much colder air behind the front surged into the area during the 27th, while a series of upper disturbances (Figures 1 and 2) gradually deepened a trough over the eastern U.S. and provided a prolonged period of arctic air moving across the Great Lakes and into the southern Appalachians. The character of the snow showers went from banded to patchy in nature during the afternoon of the 27th, then back to banded during the following night into the 28th. (See Figures 3 through 6 below). The final disturbance (Figure 2) moved across the region around the morning of the 28th. Snow showers brought several periods of accumulating snows to those favored upslope areas (see storm total map below). For a perspective of the terrain influence, see the images below or click here for a side by side view. The summary for the event shows over a foot of snowfall fell near the Tennessee/North Carolina State line, and across the northwestern sections of Greenbrier County.
