Interesting from NWS GSP:

Quote

As of 920 PM Monday: The upper low embedded within East Coast trough
is centered over the Tidewater region to our NE. Since sunset, have
seen an expansion of light radar returns at elevations apparently
below the Blue Ridge Escarpment; this appears to be due to a
mountain wave, but per nighttime microphysics satellite product and
IR cloud top temps, the lower clouds NW of the Escarpment are likely
dropping some flurries or light snow within the radar-shadowed
areas. The setup looks to have been captured well by the NAMNest,
so it was blended into the overnight fcst to expand the light snow
and/or flurry mention southeast into the Piedmont. With the upper
low in place, can`t absolutely rule out flurries anywhere in the
CWA, but have kept the mention where the low-level moisture is
better. On that note, continued drying/downsloping should diminish
the Piedmont activity in the early morning.

The NW flow snow will become more of a pure upslope event following
the loss of the dynamic lift Tuesday morning. Orographic lift across
the TN border and Smokies still looks to produce over a foot of
snow by the end of the period Tue evening. Most of the higher
amounts associated with this event will be above ~3500-4000`,
where thermal profiles are favorable for snow with heavy snowfall
rates. See no reason to make significant change to existing snow
amounts; do not yet have enough obs/measurements to improve on
what we`ve got. Did rerun accums with latest PoPs, which made
minor changes (new WSW out soon). The snow will diminish a bit
more quickly in the afternoon/evening as drier air filters in. The
Winter Weather Advisory is still in effect for elevations below
3500`, but those in populated areas along the TN border and down
the valley away from the TN border, snow amounts lessen by a lot
in these areas compared to the higher peaks. Expect a general 1-3"
in these locations, while areas under the warning will exceed 4+".

I agree. Temps are right, brutal wind chills, about a 15:1 ratio, sideways snow. I bet Bucket's getting smoked right now.

Just checked and I've picked up 4" on my board since dusk, even with all the wind. There's gonna be some big drifts beside the house in the morning!

 

Oh, and I got my propane today!

Got my inch I was hoping for, ended up with a storm total of 1.75" and although its still snowing, its so wind whipped and small in size i doubt we add much more. 

Cat has a running storm total of 6" 

  • 2" Sun PM - Mon AM
  • 4" Mon PM - Tues AM
  • Still light - moderate snow up there, maybe another 0.5 - 1" before its all said and done.

Nothing coming down in NW Catawba here in Hickory, despite the radar returns indicating otherwise. The direction of this flow is different than normal, though, which may explain the returns that are breaking containment. It's almost due north, just a few degrees west of that.

Saw a few flurries under those radar returns last night after 10pm here in SE Caldwell County. Was hoping for more given the returns. Looks like we may have another shot at some more flurries today with more returns breaking containment.
