NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
741 PM EDT Thursday Jul 30 2015 


Synopsis... 
a cold front will continue to move through the area this 
afternoon...and settle southeast of the area tonight through Friday. 
The front and associated deeper moisture will likely remain confined 
along the southeast coastline through the weekend...with slightly 
cooler temperatures and much drier air expected over the forecast 
area. Low level moisture will gradually return early next week as 
another cold front approaches from the north. 


&& 


Near term /through Friday/... 
as of 740 PM EDT Thursday...other than slight increases to middle 
chance probability of precipitation along the i85 corridor over the next few hours per 
latest cam guidance...current forecast remains on track. Did make minor 
tweaks to temperatures/dews and sky to account for most recent Sat/obs. 


Previous discussion... 


As of 215 PM...a vigorous short wave trough continues to progress across 
the Great Lakes into the northeast states tonight...bringing some 
height falls atop the County warning forecast area near the base of the trough axis. 
However...overall forcing is fairly weak this far south...as 
vorticity is being sheared out. At the surface...a cold front is making 
inroads into the Piedmont off the Blue Ridge. Some metars are 
reporting a notable drop in dewpoints from the lower 70s to upper 60s. 
However...the drier air is still back over central KY/TN. Cape is 
decent along and ahead of the front...but deep convergence must be 
lacking...because convection has been unimpressive so far given the 
instability. I will keep a chance pop through the rest of the afternoon...then taper 
probability of precipitation from northwest to southeast this evening. 


Overnight...dry air will continue to filter in from the north...thus 
ending probability of precipitation. Forecast soundings show lingering moisture under a developing 
inversion...so there will be some lingering stratocu through 
daybreak...especially along and southeast of I-85. Min temperatures will be a 
couple categories cooler than in recent days across the northern 
zones...but still above normal across the southern half of the County warning forecast area. 


Friday...as an upper trough digs across the Appalachians...dry high pressure 
will continue to build in from the northwest. Guidance in good 
agreement on deeper moisture being shunted south of the County warning forecast area across 
the Gulf states and midlands. So expect a dry day on tap. 
Thicknesses do not fall much behind the front...but dewpoints should drop 
into the 50s to lower 60s across the entire area during the afternoon. So it 
should feel much less muggy. Highs will still be a category or two 
above normal...except near normal in the high elevations. 


&& 


Short term /Friday night through Sunday/... 
as of 230 PM EDT Thursday...the weather for the weekend looks about 
as quiet and uninteresting as it gets for middle-Summer across the 
western Carolinas and northeast Georgia. Temperatures should be 
slightly above normal through the period...but the main story will 
be the relatively dry air mass. In the wake of the cold front 
passage...the high pressure air mass to the north and northwest will be slow to 
modify through the weekend. A blend of the models suggests dewpoints 
dropping into the 55 to 60 range Saturday and Sunday...which will 
drop the afternoon relative humidity down near 30 percent. That combined with some 
relatively warm air at middle levels will all but eliminate most of the 
potential for positive buoyancy...which means a very low potential 
for deep moist convection. Although the remnant cold front boundary 
will be close...it should be to the south of the forecast area. 
Thus...expect only an isolated shower over the balsams Saturday 
afternoon...otherwise the entire area should be dry through midday 
Sunday. Will allow for some modification by Sunday afternoon...so a 
slight chance pop will be included mainly over the mountains 


&& 


Long term /Sunday night through Thursday/... 
as of 230 PM EDT Thursday...the medium range begins Monday with 
slight height rises in the upper trough hovering over the eastern 
Seaboard. Monday and Tuesday are marked by continued airmass drying 
and low level q-vector divergence...with both major global models 
showing only minimal quantitative precipitation forecast response over the forecast area. Model 
agreement wanes significantly after Tuesday...as a frontal boundary 
swings out of the Midwest. The GFS passes the front through the area 
on Wednesday...while the European model (ecmwf) hangs up the boundary over the Ohio 
River valley. Quantitative precipitation forecast response is only slight in the GFS due to lack of 
deep layer moisture and less than impressive instability...so kept 
probability of precipitation to slight chance or lower with best chances over the higher 
terrain. The upper trough will continue to hang over the eastern 
Continental U.S. Through the end of the period...and the trough axis finally 
approaches and forces another more substantial front through the 
area late Thursday or Friday. Exact timing of the front will need to 
be hashed out as models hopefully come into better agreement later 
in the period...though quantitative precipitation forecast response is again not particularly 
impressive due to lack of instability. Maximum temperatures will start just 
above climatology...and rise a degree or two by the end of the period. 


&& 


Aviation /00z Friday through Tuesday/... 
at kclt...VFR through the period despite weak cold frontal passage this 
evening. Initialized taf with vcsh as latest convective allowing 
guidance favors development along/south of the i85 corridor through 
03z-04z. Confidence is low due to the poor verification of the 
guidance over the last 6 hours...thus opted not to include tempo. 
Otherwise...the front will slide through overnight with 5-10kt winds 
solidly out of the north-northwest through the remainder of the period with some 
minor gusting possible around daybreak...however not in taf. Skies 
will scattered after any possible convection tonight leading to few low 
stratus under high level cirrus by morning. Soundings are rather 
dry aloft on Friday thus removal of any high clouds seemed warranted 
therefore the remainder of the taf beyond 18z features only low VFR 
few cumulus. 


Elsewhere...VFR and thus similar to that of kclt above with a weak 
cold frontal passage occurring this evening. All sites aside for kavl feature 
low confidence thunderstorms in the vicinity as the atmosphere is most stable over the 
mountains. Otherwise...removed all weather mention from all sites around 
the 03z-04z timeframe leading to prevailing 06-10kts north-northwest winds by 
morning along with few low VFR stratus and high level cirrus. 
Eventually expecting the middle/upper levels to dry leading to only low 
level few VFR cumulus by midday at the SC sites with sky clear at the NC sites. 


Outlook...expecting generally dry and quiet weather through the 
weekend with a gradual increase in chances for showers/thunderstorms 
and restrictions for the start of the new work week.
