NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
624 am EDT Thursday Oct 23 2014 


Synopsis... 
dry high pressure will remain in control of the weather through 
early next week. 


&& 


Near term /through tonight/... 
through the early morning...clear skies will prevail and clouds 
across the western mountains will continue to dissipate as an upper trough pulls 
NE. Patchy to areas of Fr are likely across the southern mountains and extreme 
NE Georgia before heating commences around 13z. Temperatures and dew point/S look good 
with only minor adjacent needed to cover the next few hours. 


430 am EDT update...made minor changes to the sky grids. The temperature 
and dew point grids were mostly in line with the diurnal curve. Mesonet observation 
across the Fr.Y area indicate a good chance of current frost or the 
development of frost in the next couple hours across most of the 
affected zones. 


As of 230 am EDT...strong Canadian hipres will continue building 
into the region today supported by short wave ridging and subs aloft. This 
will create dry conds through the column with precipitable waters  ranging from 
0.25 to 0.35 west/east during maximum heating. Clouds will be hard to 
come by once again tday with increasing cirrus by late afternoon from 
the west ahead of an ulvl trough. The surface p/gradient will loosen over the 
area as well with winds remaining in a weak northwest/ly config throughout 
the day. Early to middle morning gusts across the mountain valleys will 
relax in the afternoon as the bl loses momentum energy. Maximum temperatures 
will be close to normal...likely a couple degrees below a low level 
thickness trough slowly modifies in good insol. 


The overnight will feature the advance of an 500 mb short wave trough. This trough 
will be limited in moisture and only bring ulvl clouds through 
daybreak. The latest NAM and GFS soundings account for these 
clouds...but still develop weak to moderate surface/based inversion 
across the County warning forecast area. Surface dew point/S will be too low for much of a visibility 
concern...but dew point/S near freezing will make areas of frost probable 
across all the NC mountains a Fr.Y will be issued for the NC mountain 
counties not already turned off for the season by the earlier Oct 
5th freeze. Mins will range from the lower to upper 30s across the 
mountains and fthills...to the lower 40s non/mtns. 


&& 


Short term /Friday through Saturday night/... 
as of 315 am Thursday...classic autumn weather will continue 
into the early part of the weekend...as another short wave dives out 
of the Midwest to reinforce the mean trough over the eastern states. 
This wave may bring a brief period of middle/high clouds on 
Friday...and the remotest of mountain shower chances...but overall 
the impact on sensible weather will be minimal. By Sunday...heights 
will begin to rise in response to a building ridge over the central 
Continental U.S.. therefore...while temperatures will begin the period very close to 
climatology...maximum temperatures Sunday are expected to creep a category or so 
above normal 


&& 


Long term /Sunday through Wednesday/... 
as of 255 PM Wednesday...guidance in good agreement indicating a pattern 
change during the medium range...with the eastern trough being 
replaced with a ridge through Tuesday. Southwesterly flow aloft develops Wednesday as 
the ridge axis moves east and a trough moves into the central Continental U.S.. 
a dry front crosses the area Sunday with high pressure building in 
Monday and sliding across the area Tuesday. The guidance differs on the 
strength and speed of the trough...with the GFS weaker and faster 
and the European model (ecmwf) stronger and slower. This results in the GFS 
bringing a weak front into the mountains late Wednesday...and the European model (ecmwf) 
bringing a stronger front with good southerly flow into the western County warning forecast area by 
that time. For now...have limited pop to slight chance for the NC mountains 
and northern tier...in line with a model blend...given the uncertainty. 
Mild temperatures sun see a brief cool down Monday...then show a warming 
slow warming trend through the end of the period. 


&& 


Aviation /12z Thursday through Monday/... 
at kclt and elsewhere...VFR flight conds through the taf period. High 
pressure will continue to build across the region with supporting 
ridging/subs aloft. This will create very dry profiles with sky clear all 
sites through most of the daytime. Frost development is possible at 
kavl and khky before melting after 13z. Weak winds will remain aligned 
up valley at kavl and generally north-northwest/ly at all other terminals except 
kand...where flow around the terrain will make for west/ly flow in the 
afternoon. Upper clouds will begin to move in from the west 
during the second half of the taf period. 


Outlook...quiet weather will continue across the region...as deep 
layer ridging settles in through this weekend. 


&& 


Gsp watches/warnings/advisories... 
Georgia...frost advisory until 9 am EDT this morning for gaz010-017. 
NC...frost advisory from 2 am to 9 am EDT Friday for ncz033-049-050- 
053-063>065-501-503-505-507-509. 
Frost advisory until 9 am EDT this morning for ncz063. 
SC...none.
