New MD covers the NW corner of the state. Another MD just a hundred miles east for a severe watch possibility. 

 

MD 28 graphic
   Mesoscale Discussion 0028
   NWS Storm Prediction Center Norman OK
   0413 AM CST Mon Jan 03 2022

   Areas affected...Parts of southwest through northern Virginia and
   central Maryland

   Concerning...Heavy snow 

   Valid 031013Z - 031415Z

   SUMMARY...Heavy snow rates around 1-2 inches per hour and
   occasionally greater appear increasingly possible along and to the
   east of the Virginia Blue Ridge Mountains, into the Greater
   Washington D.C. and Baltimore Metropolitan areas, through 7-10 AM
   EST.

   DISCUSSION...Precipitation rates have increased along a frontal zone
   north through north-northeast of a deepening surface cyclone center
   across the South Carolina Piedmont.  Although temperatures near the
   surface and in layers aloft are generally still warm to the east of
   the Appalachians, across much of the southern Mid Atlantic, a
   combination of strengthening mid/upper forcing for ascent and
   gradual low-level cold advection on northerly surface flow is likely
   to contribute to profiles increasingly conducive to snow.

   Surface temperatures are already approaching freezing across much of
   the Greater Baltimore and Washington D.C. metro areas into the
   immediate lee of the Blue Ridge, where strengthening mid-level
   frontogenetic forcing for ascent appears likely to become focused,
   beneath an intensifying divergent flow field between coupled upper
   jets.  Forecast soundings suggest that lift will become increasingly
   maximized within the dendritic growth layer through 12-15Z, in the
   presence of seasonably high moisture content (including precipitable
   water on the order of .75-1.0 inches) supportive of 1-2 inch per
   hour snow rates, and perhaps occasionally heavier.

Thundersnow!

Big flakes blowing around here in Southern Jackson, just a dusting on grassy and elevated surfaces so far. 32.2 and dropping.

  • Crossroads cam looks solid with 1 - 2" on the ground, same for Highlands but looks a bit more (6am)
  • Someone i follow on twitter (and encouraged to join the forum) is out of Yancey at 4500', 1/2 mile from the TN line and is reporting 7" as of 6am. 
  • 2" here in the valley (Waynesville), about a mile from downtown the way the crow flies. 

Congrats everyone!

Amazing to see that funnel of cold air come right how into Henderson county as shown on the models. Yard is white, rates are moderate. 
Edit: The WIND! Just heard a tree fall somewhere in the neighborhood. 
Yeah this wind is intense. I'm concerned about losing power. The trees are moving a lot more than I like right now.

When these gusts hit it’s a bit crazy, strongest yet.  I think I can hit 6” here if I can get some of those heavier returns to rotate in from TN, I bet my ol’ bugaboo of dendrite size struck again from what I’ve seen since 4 am.  Hard to pile up above 6” with lackluster flakeage for lack of a better term.  One of these days I’ll get some quarter-sized flakes.
