NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
451 am EDT Tuesday Oct 21 2014 


Synopsis... 
a weak cold front will cross the region from the northwest today 
followed by dry northwest flow on Wednesday. Dry high pressure will 
then return on Thursday and linger into the weekend. 


&& 


Near term /through tonight/... 
430 am EDT update...low level stcu is becoming more widespread across the 
NC mountain spine and the sky grids were adjacent up a little across the western 
portion of SW mountain zones. Areas of dense fog is developing across the 
little Tennessee Valley while other mountain valleys are seeing less dense fog 
setting up. The French Broad valley could drop into patchy dense fog 
over the next few hours. 


As of 245 am...an upper level trough remains progressive through the 
period...bringing a clipper low across the middle atl through the day. 
Prefrontal moisture will be glakes enhanced bringing increasing 
cloud cover to the NC mountain spine and northern mountain counties this 
afternoon/evening. Along with good mech lift...there will be the 
presence of ulvl divergence across the mountains aiding in stratiform precipitation 
generation. Thus have bumped probability of precipitation up to the chance range centering 
on 18z for a few hours. With the progressive nature of the parent 
low...have allowed probability of precipitation to drop to isolate late afternoon and evening 
as upstream moisture becomes shallow and less available. Mixing to 
800 mb will produce low end to moderate wind gusts this afternoon across 
the mountains and fthills. Maximum temperatures will be right around normal over the 
mountain valleys and a few degrees above normal non/mountains in downslope 
enhanced warming. 


There will be an increasing pgrad with the clipper trough late 
afternoon across the mountains developing east through the County warning forecast area 
overnight. BUFKIT time heights show reinforcing sigma cold air advection beginning 
around 02z with gusts reaching 30 kts or so over the mountain valleys...and 
likely 40-45 knots gusts across the higher elevations. Expect these 
winds to continue through the overnight as a California airmass mixes 
in...diminishing somewhat around daybreak. No wind advection will be issued 
as the criteria needed is about 8-10 kts higher for sustained winds 
and gusts. Min temperatures will drop to about 5 degrees f below normal with 
Montana Mitchell likely dropping below freezing. Temperatures and dew points will 
approach the frost range over some higher mountain elevations...but 
continued momentum transfers will preclude the need for a Fr.Y. 


&& 


Short term /Wednesday through Thursday night/... 
as of 205 am EDT Tuesday...the County warning forecast area will remain within deep cyclonic 
flow on Wednesday and as cooler air permeates the region...maximum 
temperatures should be several categories cooler than Tuesday. Save 
for some upslope cloudiness across northwest NC...sunshine should be 
plentiful...accompanied by locally gusty northwest winds. Expecting 
deamplifying flow and rising heights atop the region for Thursday 
as upper level cyclone center wobbles further up the NE Atlantic 
coast. Deep layered dry air should allow for abundant sunshine and a 
category or two warmup...but still below climatology...from Wednesday/S 
readings. 


&& 


Long term /Friday through Monday/... 
as of 225 am Tuesday...medium range models depict little in the way 
sensible weather across the southeast Continental U.S. To round out the workweek with a 
developing weakly forced shortwave trough aloft and broad surface Lee 
troughing. Maximum temperatures will continue to rebound...nearing 
climatology. A degree or two warmer than persistence will be featured for 
Saturday within dry northwest flow aloft...and yet warmer for Sunday as 
deep layered ridging noses eastward. At this juncture...it still 
looks like ridging will hang on through day 7...dry and continued 
mild for Monday. 


&& 


Aviation /09z Tuesday through Saturday/... 
at kclt...VFR conds through the period. Middle level clouds are pushing 
off to the east currently with drier air mixing in through the 
afternoon. Downslope warming will allow good mixing with some low 
end gust possible this afternoon. Few fair weather cumulus will likely develop 
this afternoon as well...but not included in the taf at this time. Winds 
will remain west/ly with veering occurring after 20z. 


Elsewhere...areas of morning fog/br developing mainly across the mountain 
valleys and into the northern NC fthills. Kavl should see a dip into IFR 
visibility...while khky will likely be held at MVFR...but may need a tempo 
IFR. Moderate gusts late this afternoon continuing through the 
period at kavl and khky with clipper front and cold air advection pushing in. 
Non/mountain sites should see MVFR visibility around daybreak with increasing 
west/ly to northwest/ly winds middle day veering around 00z. 


Outlook...blustery and cooler for the middle part of the week...then 
warming the latter portions into the weekend. Gusty mountain winds 
Tuesday night seem to be the only aviation concern apparent at this 
time...as air will dry and winds become light.
