NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
701 PM EST Monday Jan 26 2015 


Synopsis... 
in the wake of a strong departing low...dry high pressure will 
spread back over the region from the northwest tonight and tomorrow. 
Another cold front is expected to cross the region late Thursday 
into early Friday with another round of high pressure in its wake. 


&& 


Near term /through Tuesday/... 
645 PM update...surface observation from the northwest NC mountains indicate some snow 
showers are occurring there...evidently from below radar beam level. 
The smokies/balsams however appear to have the best chance of seeing 
notable accumulation...with the plume of moisture from Lake Michigan 
approaching along with the channeled vorticity maximum. Light radar 
returns accordingly are seen over the Cumberland Plateau. So it 
appears the southern half of the mountain zones will be the focus for precipitation 
in the evening...and perhaps the rest of the night with latest model 
forecasts showing the best setup for northwest flow in the north being right 
now. Will continue the west-southwest as-is but provide updated snow totals 
and a revised text product by 0300z. 


As of 245 PM EST Monday...broad full latitude longwave upper trough 
remains across the eastern Continental U.S. With sharp ridging across the west. 
Closer to home...brisk northwest flow amongst the amplified upper 
pattern and pooled low level moisture continues to yield light 
upslope snow showers along the Tennessee border. Further east...forecast 
features decreasing probability of precipitation across NC Piedmont as earlier shower 
activity has diminished with only a few light echoes evident on 
radar. Models continue to trend towards a brief lull in northwest 
flow snow shower activity along the Tennessee border counties before a 
second round of channeled vorticity slides through the region 
tonight. Low level moisture associated with this energy impulse 
will pool along the mountains once again leading to re initiation of 
snow showers. Thus...likely/categorical probability of precipitation are featured in the 
forecast. Model quantitative precipitation forecast continues to yield sub warning criteria snow 
totals thus opted to extended current advisory through noon Tuesday 
to also include expansion northward into the northern mountains of 
western NC. Forecast accumulations will generally remain around 2 
to 3 inches with some 4 inch totals possible along the higher peaks 
and ridgetops of the smokies by morning. In addition to the 
snowfall...gusty northwest winds will prevail through much of the 
night with some of the higher elevations sites experiencing gusts 
near 40mph...while the lower elevations top out with gusts nearing 
25-30mph. 


Outside of the mountains...conditions will gradually improve through 
the overnight with skies beginning to scattered near midday Tuesday. 
Downsloping flow will yield temperatures just below normal despite 
cold advection pattern. 


&& 


Short term /Tuesday night through Thursday night/... 
as of 230 PM Monday...the first part of the short range looks like 
the quietest part of the entire forecast. Any remaining northwest flow snow 
showers over the northern mountains of NC should taper off right away 
Tuesday evening. The axis of the upper trough should move slowly off the East 
Coast Tuesday night...which will keep a dry northwest flow overhead. An 
upper ridge will slowly build in from the west on Wednesday with the 
axis of the upper ridge moving overhead Wednesday night. This will 
support dry and cool high pressure that will keep temperatures generally a 
category or so below normal. 


On Thursday...the models show a pair of short waves moving through the 
Midwest and around a mean trough over the east. The first wave should 
stay over the Ohio Valley on Thursday afternoon. Warm advection ahead 
of the wave may help to develop some light precipitation across the forecast 
area...with the best chance over the mountains forecast soundings suggest 
this will be an elevation-dependent rain or snow situation. There 
should be a small chance for precipitation outside the mountains that should 
fall as rain. Temperatures were undercut from the guidance...with the 
expectation that increasing clouds and some light precipitation will 
continue to keep temperatures below normal. The second wave should help to 
drive a cold front across the western Carolinas Thursday night. Most 
of the precipitation with this feature will be confined to the mountains 
improving moist upslope flow behind the front should maintain a 
chance of precipitation on the Tennessee border through at least daybreak on 
Friday. This should be in the form of snow showers owing to the cold 
advection behind the front. Min temperatures east of the mountains should be above 
normal because of lingering clouds. 


&& 


Long term /Friday through Monday/... 
as of 215 PM Monday...a prominent trough axis will move quickly east 
of the forecast area Friday morning and then off the eastern Seaboard 
through the day. Shallow moisture in the northwest flow cold advection 
behind the trough could linger through late Friday morning...but with 
little to no additional snow accumulations in any upslope showers in 
the western mountains maxes will fall below climatology...perhaps 10 degrees or 
more below climatology in the NC mountains. 


The upper level flow pattern will become zonal through Sat with surface 
high pressure likely building over to the north of the region. A steady 
increase in middle and high clouds is expected. Model differences then 
appear through the latter half of the weekend...with the GFS 
generally faster than recent European model (ecmwf) runs in featuring a northern stream 
wave digging into the Midwest on Sunday. The 00z operational European model (ecmwf) 
was a bit slower...but the 12z run is now closer to the GFS timing 
on the wave. The main sensible weather difference for Sunday is that 
the faster GFS timing allows precipitation to arrive by 
daybreak...with a southern tier freezing rain/northern tier snow and sleet 
threat...with relatively prominent cad setting up from the NE. 
Profiles would then warm for the peak of the warm advection...with 
mainly a rain ptype except for lingering freezing rain in any cold pockets 
just east of the Blue Ridge. The European model (ecmwf) has a slower onset of 
precipitation...with less morning freezing rain threat...much weaker 
cad...but then more of a rain versus snow ptype issue throughout the 
whole event. Sunday temperatures have been lowered slightly...and ptypes 
remain rain/snow. 


Differences are more Stark Sun night into Monday. The GFS drives a 
cold front through the region and dries things out...other than any 
lingering northwest flow moisture in the western mountains the European model (ecmwf)...on the other 
hand...develops a surface wave over the southeast and keeps heavy precipitation 
in the region Sunday night into Monday. Associated ptype issues 
would continue depending on the surface low track. Will continue to keep 
all ptypes rain versus snow throughout given all the uncertainty in 
thermal profiles. 


&& 


Aviation /00z Tuesday through Saturday/... 
at kclt...VFR but with a ceiling persisting most of the evening. Bases 
will gradually lift and scatter...but a pocket of midlevel moisture 
will pass overhead late tonight bringing ceilings back for a time 
lasting through the morning. Northwesterly winds are likely to gust at least 
occasionally this evening in cold advection and tight pressure 
gradient. Mixing will diminish after midnight which should allow 
winds to weaken. A few gusts are likely to return Tuesday but a fairly 
steady northwest breeze will prevail. 


Elsewhere...VFR east of the mountains...where moist northwest flow will continue 
through tonight and Tuesday morning beneath a persistent upper trough over 
the East Coast. A channeled stream of vorticity may provide some 
enhancement to forcing but snowfall rates will mainly be determined 
by wind speed and low level moisture. Kavl will continue to see MVFR to 
low VFR clouds through morning though any precipitation will remain nearer the 
tenn border. Northwesterly gusts will affect all the sites this evening 
before diminishing with the pressure gradient later tonight...but 
they will pick back up with mixing by late morning. 


Outlook...a series of clipper systems will bring periodic chances 
for snow showers...mainly to the mountains through the week. Most of 
these snow showers will remain west and north of kavl...but brief 
periods of restrictions and snow showers cannot be ruled out there. 
Otherwise...mainly VFR conditions are expected.
