   Areas affected...WV...northwestern VA...western MD...and far
   southwest PA

   Concerning...Winter mixed precipitation 

   Valid 020759Z - 021200Z

   SUMMARY...Several hours of freezing rain are possible this morning
   from WV into northwestern VA, western MD, and far southwest PA.
   Highest freezing rain rates are expected along the Blue Ridge
   Mountains.

   DISCUSSION...Regional radar imagery shows a large precipitation
   shield continuing to expand northeastward across WV into northwest
   VA, western MD, and far southwest PA. Surface observations show
   several sites in southwest WV are currently reporting freezing rain
   while the sites north and east into more of eastern WV and adjacent
   northwest VA and western MD are currently precipitation free.
   Temperatures within the precipitation free zone are currently near
   freezing, and the expectation is that temperatures will cool a
   degree or two over the next free hours as the precipitation
   continues to expand into the region. Recent KRLX imagery shows a
   well-defined melting layer around 4 to 5 kft, suggesting that
   freezing rain could be the predominant precipitation type for at
   least a few hours. Some sleet could occur as well, but the
   shallowness of the cold wedge should keep its occurrence isolated.
   After an initial cool down with temperatures below freezing for at
   least a few hours, temperatures should warm again from southwest to
   northeast, with the primary precipitation type transitioning to a
   rain/snow mix.
