NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
952 am EST Thursday Nov 27 2014 


Synopsis... 
an upper level disturbance will move off to the east today... 
allowing dry high pressure to return Friday and linger into the 
weekend. Expect a cold front to slowly cross our region from the 
north early next week. 


&& 


Near term /through tonight/... 
as of 945 am...radar showing precipitation across the northwest Piedmont continues 
to move east out of the area. That said...a few sprinkles could fall 
through noon. Across the mountains...snow showers continue with another 
round of heavier snow showers upstream to move through before noon. May 
need to extend the advection into the afternoon to cover this round if it 
moves slower or lingers longer. Otherwise...expect the snow to taper 
off and become more of a higher elevation and Tennessee border area 
event with no significant accumulations from late afternoon on. Some 
cloudiness will spill out of the mountains and across the NC foothills 
and Piedmont through the day while other clouds move across the upper 
Savannah River Valley. High temperatures look on track. 


As of 645 am...the last area of upglide-induced patchy light rain is 
lifting northeast of the area...while northwest flow showers have begun to 
generate across the southern Appalachians...although they remain 
quite scattered at this time. This should change as the boundary layer flow 
takes on a more barrier-perpendicular flow. Probability of precipitation will thus ramp back 
up by mid-morning. Otherwise...a small area of dense fog developed 
earlier across the northwest Piedmont and northern foothills. This 
was handled with an earlier Special Weather Statement...and the fog should erode quickly 
as drier air filters in behind surface front. 


Upglide-forced/patchy light precipitation event will wind down over the 
next couple of hours...as water vapor imagery indicates upper level 
speed maximum is already punching into the western Carolinas. Weak 
surface boundary will push across the area through the morning... 
turning winds toward the northwest...scouring much of the cloud cover east 
of the mountains (with the exception of the I-40 corridor/western NC 
Piedmont...and allowing precipitation event to transition to more of a 
typical northwest flow snow event for the far western NC mountains it appears 
there will be a lull of at least a couple of hours in mountain 
precipitation...before the northwest flow becomes better established later this 
morning. 


Ingredients will be in place for a decent accumulating northwest flow 
event. Moisture will be deep enough...with temperatures of -10 to -12 c at 
the top of the moist layer. On the other hand...the moisture depth 
is not ideal and the bl flow could stand to be stronger. Moisture 
will also likely become too shallow to support good snow shower 
generation by late evening. Two to four inches looks like a good bet 
in the usual locations...with some locally higher amounts possible 
in the highest elevations along the tenn border. That said...this 
does not appear to be a good setup for significant valley accums 
south of the I-40...so the advisory will be changed to the high 
elevation variety this package. 


Maximum temperatures will be below normal once again today (well below normal 
in the mtns). Below normal temperatures will continue into 
tonight...although continued mixing in the northwest flow regime should 
prevent temperatures from really bottoming out. 


&& 


Short term /Friday through Saturday night/... 
as of 215 am Thursday...flattening upper flow will characterize the short 
range period...as trough pushes off the East Coast Friday and low level 
ridging returns to the southeast soon thereafter. This ridge then 
sets up over the Atlantic fostering return flow into the southern 
appalachian region. Said flow is reinforced by the broad flow around 
low pressure ejecting from the northern rockies Saturday. Weak upglide 
occurs over the Ohio/Tennessee valleys as a result...with enough moisture for 
light model quantitative precipitation forecast in those areas Saturday. The Atlantic ridge is 
prognosticated to keep this off to our west and we should remain dry through 
Saturday night. Bands of cirrus will be seen at times with passing 
pockets of upper moisture...and lower clouds increase slightly over 
the western zones late Saturday. Though Friday will be on the chilly 
side...steadily rising low level thicknesses through the period suggest 
warmer readings for Sat and Sat night...returning near climatology. 


&& 


Long term /Sunday through Wednesday/... 
as of 135 am Thursday...the medium range forecast picks up at 12z on 
Sunday with another broad 500 mb trough digging down over the far northern 
states and relatively flat upper ridging over the southeast Continental U.S.. heights 
will likely fall some early next week as the upper trough moves over 
the Great Lakes...however all of the associated upper energy will 
remain to our north. 


At the surface...high pressure will be centered off the Atlantic coast 
with southwesterly low level flow bringing warmer temperatures to the region. The next 
frontal system will approach the area early Monday and lay down across 
our northern fringe becoming a back door cold front over the next 24 
hours or so. Well defined high pressure behind the front will slide 
eastward and set up a cad pattern later on Tuesday and into Wednesday. The 
Wedge doesnt appear to hang around very long as the long range 
models spin up a northern stream low which pushes the high well 
offshore by late Wednesday. The European model (ecmwf) tries to move an associated cold 
front through the County warning forecast area late Wednesday...however the GFS is much less 
progressive with this front and keeps it to our north. No 
significant changes were needed for the sensible forecast...with only 
slight to solid chance probability of precipitation from Monday Onward...with the best chances 
mostly relegated to the higher terrain. Temperatures will warm through Monday and 
then cool again as we go into middle week and the flow becomes more 
northeasterly. 


&& 


Aviation /15z Thursday through Monday/... 
at kclt and elsewhere (except khky)...VFR conditions are expected 
through the period. The only possible exception being kavl...where 
up-valley winds could result some occasional MVFR stratocu this 
afternoon and evening along with light snow showers. Kclt may also 
see some high based VFR stratocu spilling out of the mountains 
otherwise...winds will turn toward the northwest at 10-13 kts (several kts 
stronger at kavl) by early afternoon. Gusts of around 20 kts will be 
possible at the Piedmont terminals...with middle-20s knots gusts expected 
at kavl. Winds will diminish gradually this evening into the 
overnight. 


At khky...low clouds and fog have cleared...but VFR stratocu ceilings 
will continue off and on through the afternoon as clouds spill out of 
the mountains and across the air field. VFR conditions will remain 
through the end of the period as dry air filters in behind a cold 
front. Otherwise...winds will turn toward the northwest at 10-13 kts later 
this morning. Gusts of around 20 kts will be possible. Winds will 
diminish gradually this evening into the overnight. 


Outlook...dry high pressure will set up over the area through the 
weekend. A cold front will approach from the northwest early next 
week.
