NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
209 am EDT Monday Apr 21 2014 


Synopsis... 
high pressure will weaken over the region today. A cold front will 
cross the area from the west on Tuesday...with dry high pressure 
returning Wednesday through Thursday. Another cold front will reach 
the region by Friday. 


&& 


Near term /through tonight/... 
as of 205 am...a quiet near term is expected...as sharp upper ridge 
axis translates east across the County warning forecast area. An inverted surface ridge axis also 
remains in vicinity of the region...resulting in light NE flow east of the mountains 
and dry conditions. There may be some patchy frost in the northern 
mountains...but nothing widespread across the rest of the high terrain to 
warrant a frost advisory. Temperatures currently look on track. 


Temperatures will continue to rebound under sunny skies and light winds 
today. Expecting highs to be about a category above normal...mainly 
in the middle-upper 70s across the area. 


Tonight...middle and upper level heights will fall with an approaching 
latitudinal trough and associated cold front. There will be an 
increase in middle-high clouds and even some strato-cumulus development in 
the SW NC mountains overnight...keeping temperatures elevated above normal in 
the upper 40s mountains an in the 50s Piedmont. Guidance in pretty good 
agreement on scattered showers along/ahead of the front crossing the 
Ohio/Tennessee valleys. A slight chance to low-end chance pop will creep to the Tennessee/NC 
border before daybreak Tuesday. Otherwise...it should be dry overnight. 


&& 


Short term /Tuesday through Thursday/... 
as of 205 am EDT Monday...the upper trough that will cross the eastern 
U.S. On Tuesday is not particularly amplified or coherent...but it 
should be accompanied by some degree of upper level divergence Tuesday 
afternoon. The weak upper forcing and low level convergence along the 
passing cold front should combine with modest surface based instability 
to create scattered to numerous coverage of showers and thunderstorms 
through Tuesday afternoon. The severe thunderstorm threat looks rather limited by the 
tall skinny cape in area model profiles along with modest 25 to 30 
knots surface to 3 km shear values in the westerly flow. However...the Storm Prediction Center 
calibrated sref severe thunderstorm probabilities continue to point to a northwest 
NC Piedmont maxima...where surface instability has just enough overlap 
with the best westerly shear and upper forcing for a slightly 
greater severe threat. There is not enough confidence for an severe weather potential statement 
mention of severe thunderstorms at this point. 


Expect breezy to windy conditions Post frontal passage Tuesday night into Wednesday 
morning. Broad ridging will then return Wednesday through Thursday with dry 
conditions and near climatology maxes and mins. 


&& 


Long term /Thursday night through Sunday/... 
as of 205 am EDT Monday...a northern tier vortex crossing the Great Lakes 
on Friday will not provide much amplification to the trough over the 
southern tier states. In addition...moisture looks somewhat limited with 
the Friday surface front/trough passage. However...instability is rather 
robust on both the GFS and European model (ecmwf) solutions across the Piedmont Friday 
afternoon and about 40 knots of deep layer shear is evident in profiles. 
Little change will be made to the late week forecast...with chance probability of precipitation 
for thunderstorms and rain throughout the region on Friday. 


Broad troughing will likely linger into Sat over the east...with a 
secondary cold front featuring a better thermal contrast approaching 
from the north. This front will likely stall in or near the forecast 
area over the weekend. The position of the boundary will determine 
where instability lingers/returns and this will be difficult to 
project that far out in the forecast. Will keep mainly isolated to scattered 
diurnal convective chances going over the weekend for primary mountain 
and SW sections. 


&& 


Aviation /06z Monday through Friday/... 
at kclt...a quiet taf period as surface high pressure axis translates across 
the area...with generally sky clear or few/sct250 through the period. Light 
winds will favor a NE direction until about noon...then become 
variable during the afternoon before switching to SW. 


Elsewhere...similar to kclt above...with light NE winds or variable 
through middle morning...then favoring SW by early afternoon. Forecast soundings show 
possible some high-based cumulus developing across the NC mountains and 
into the upstate late afternoon/early evening...but otherwise cirrus only 
clouds expected through the period. 


Outlook...a fairly wet frontal system...with Piedmont 
thunderstorms...is expected on Tuesday...with drying returning middle week. 


Confidence table...
