And this my friends are why half our Mets are bald???… no shame my lady or gentleman friends.. I added extensions to have longer hair! Winter precip in the southeast… the most difficult concept to master.. it defies the laws of physics!

Yes that is 99.5 percent ZR and sleet

Hey its not even started yet bro. Could completely change for you guys.
That is generator worthy here.
I started a thread for the coastal potential it's probably DOA but there's no reason for us to sit here talking over each other about 2 independent things
Lee side is a no go. Per usual with this type of setup. Cant fool Jimmy

I feel like the hi-res models aren't quite in range in this setup to hone in on things just yet. I like a GFS/Euro blend right now in terms of the orientation of the snow band, but with throwing in a bit more mixed precipitation on the southern edge as the globals will struggle to capture the warm advection warm nosing compared to the hi-res modeling. NW Mississippi looks like the best spot to me for snow.

SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
As of 155 pm EST Saturday: A broad upper trough will retrograde
slightly toward the center of the country and sharpen during the
short term, as a series of short wave troughs dig across the
northeast quadrant of the country. The upper jet will strengthen
atop our region early in the period, with resultant tightening of
the temp gradient w/in pre-existing baroclinic zone allowing for
frontogenesis/isentropic lift across the TN Valley and the southern
Appalachians late Sun night, and especially through the daylight
hours. Light precip should blossom across this region during that
time, with forecast soundings indicating a rain/snow proposition for
the NC mountains.
For the Smokies and vicinity, soundings support mostly snow even in
the lowest valleys, with perhaps some rain mixing in at times.
Forcing and moisture will be such that liq equivalent QPF will be
marginal for warning-criteria snowfall, but strong SW flow could
provide enough enhancement from mech lift to push some locations in
southwest NC over the top. Considering this, along with model trends
(which have been steadily trending wetter), and with the expectation
that the higher elevations will be exclusively snow lends enough
confidence to issue a Winter Storm Watch for Graham and Swain
Counties from 12Z Mon through 12Z Tue. Considered a high elevation-
only Watch, but prelim accums are close enough in the valleys to
issue for all elevations. Locations to the north and east...mainly
across the TN border counties could see solid Advisory-level
snowfall. Otherwise, PoPs Monday range from likely along the TN/NC
border, to slight chances across the foothills. If precip is able to
break containment into the I-40 corridor across the foothills, some
-SN will be possible there.
There is quite a bit of uncertainty as to how things will evolve Mon
night into Tue, as models are at odds in terms of their handling of
a short wave trough digging toward the Southeast by the end of the
period...and its potential consequences for coastal surface
development. Guidance sources are split in spreading light precip
into the eastern half of our CWA during this time frame.
Nevertheless, there is enough to go on to introduce small PoPs
across the Piedmont Tuesday. If precip occurs, rain is the most
likely p-type, but there could be a brief transition to snow as
colder air begins spilling into the area at the end of the period.

RGEM another huge hit northern Mississippi and NW Alabama with the initial precip
Damn these RGEM totals are gonna be nuts
