12Z NAM shows a decent area of snow forming over central/eastern KY and eastern TN late Tuesday into Wednesday.

It appears like there is a wildfire just north of Amarillo that is depicted on radar.

Yep, powerlines knocked down by high winds behind the dry line. Some places up there haven't seen measurable precip in well over 100 days. Unreal.

Severe storms today, snow flying on Wednesday over much of the state.  Typical March weather in all it's lovely madness.

I know the severe event is the sexy talk right now but things might be shaping up for a good snow event in less than 48 hours.

Parts of central and all of eastern Kentucky is now under a winter weather advisory for 1-3" of snow.  MRX will probably issue one for the upper plateau, northeast valley and mountains once the current severe weather episode ends.  The mountain areas of North Carolina are already under a Winter Storm Watch.

MRX:

Quote
An upper trough will move across the lower Ohio and Tennessee
Valleys into the southern Appalachians through the period. A
frontal boundary will also move across this afternoon with
widespread showers and possibly thunder far eastern counties
developing this afternoon.

The cold air behind the frontal passage will allow the rain
showers to change to snow showers across the higher terrain first
this evening, and then into the Plateau overnight. For the valleys
of southwest Virginia and northeast Tennessee and gradual change
over to snow showers is expected early Wednesday morning.

Due to low-level instability, orographic lift, and deformation
zone wrapping around upper low, a prolonged period of snow showers
are expected across the area through Wednesday evening. Snow
accumulations will be elevation dependent given the relatively
warm ground and strong ultra-violet radiation melting snowfall.

Have issued a winter storm warning for the higher elevations of
southwest Virginia, such as High Knob, and the far eastern
Tennessee Mountains. Places like the higher terrain of the Smokys
will likely see the greatest snow accumulations.

Light snow accumulations are also possible over the lower
elevations of southwest Virginia and northern Plateau. May need to
issue a winter weather advisory there later this morning.

Besides the snow, freezing temperatures are expected area-wide for
Wednesday night/Thursday morning. A freeze watch will likely be
issued later today.

Looks like a typical March snow--most accumulation elevation driven.  Wednesday will be a "novel" snow day for the central valley with snow falling for a big part of the day, but little accumulation to show for it. Happy Spring!

Blue skies here this morning will allow for some solar heating.  We'll probably see some thunder this afternoon as the cold air moves in aloft with the upper low.

Area Forecast Discussion...UPDATED
National Weather Service Morristown TN
1015 AM EDT Tue Mar 20 2018

.DISCUSSION...
A cold front is currently located just northwest of our area
across eastern and southern KY, with a line of showers just ahead
of it moving into SW VA. Meanwhile, a mid-upper level trough is
located near western KY. As these features move through our area
this afternoon and evening, showers are expected to increase in
coverage. With some breaks in the clouds this morning, there
should be some instability to initiate shallow, low-topped
convection. An isolated thunderstorm cannot be ruled out as
forecast soundings this afternoon show fairly steep lapse rates
in the 850-700 mb layer.

I've already noticed towering cumulus developing as the fog lifts.  I wonder if we'll see any small hail or graupel today with the colder air aloft?
