NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
349 am EDT Sat Jul 4 2015 


Synopsis... 
a broad upper level trough will remain over the southeast through 
Monday...providing lift and maintaining elevated rain and 
thunderstorm chances each day. Slightly drier conditions return 
Tuesday and Wednesday...before another front pushes across the 
southern Appalachians by the end of the work week. 


&& 


Near term /through tonight/... 
as of 325 am EDT Saturday...rather robust band of convection 
associated with deep layer instability continues to slide along the 
i20 corridor from eastcentral Georgia into the SC midlands. Latest Storm Prediction Center 
mesoanalysis continues to indicate a modestly unstable environment 
over these areas...while showing a rather sharp decreasing gradient 
northward into the SC upstate. Further west another band of broken 
convection stretched in a north/south orientation from southeast Tennessee 
southward to around Columbus Georgia. It is this convective element that 
latest cams forecast will survive/advance into northeast Georgia and the 
western Carolinas by around daybreak. 


For the remainder of the Holiday...the pattern is somewhat similar 
to that of yesterday as it is highlighted by a broad positive tilted 
upper trough...and a quasi stationary convergence axis across the Tennessee 
Valley. This surface feature combined with lobes of vorticity 
around the upper trough...all enhanced by rear entrance region of 
upper jet...will support scattered/numerous showers and 
thunderstorms once again today. Also similar to that of yesterday 
will likely be the evolution of the instability parameters across 
the region which will be greatly impacted by am 
convection...especially over the southern tier of the forecast area. 
20-30kts 0-6km bulk shear will once again be present in the 
profiles...however its seems the above mentioned faults in 
instability will prevail leading to only a few strong storms at best 
this afternoon. Precipitable waters  remain around 2 inches which will lead to 
continued flash flooding threats where any cell training occurs. 
Plans are to expand/extend current Flash Flood Watch to account for 
most recent precipitation/ffg values in the near term...and beyond into the 
short term. Latest quantitative precipitation forecast remains very similar to that of last forecast 
cycle which focuses mainly on the SW mountains of western NC...and 
northeast Georgia where upwards of 1-2 inches is featured. 
However...those numbers could be understated if/when training of 
cells occurs. 


All said...the Independence day forecast features scattered to numerous 
probability of precipitation for rain showers/thunderstorms and rain this morning across the upstate and upper Savannah 
River valley...before tapering to chance levels this afternoon. At 
that time the highest probability of precipitation will reside over the high terrain...and 
also along and north of i40 in the western NC Piedmont where likely 
levels are mentioned. Skies will be mostly cloudy with below normal 
temperatures. 


&& 


Short term /Sunday through Monday night/... 
as of 315 am Independence day...on Sunday the key features will 
continue to be a broad upper shortwave centered over the upper tenn 
valley...and a weak low level boundary over the Carolinas. 
Differences in the pattern are minor compared to Saturday. Deep 
moisture will actually be slightly better...characterized by precipitable water 
values above the 90th percentile per Storm Prediction Center radiosonde observation climatology. This is in part 
due to a better Gulf connection...on account of low level winds 
backing to southwest immediately ahead of the upper trough. This will 
enhance upslope forcing into the SW portion of the County warning forecast area as well. 
Furthermore wind profiles will feature weak and nearly unidirectional 
shear. The concern accordingly will continue to be for thunderstorms 
producing heavy rain and potentially training. With the ingredients 
continuing to be in place for a flood threat...we have extended the 
Flash Flood Watch another 24 hours...now ending at 00z Monday. Also 
the area has expanded to all of Jackson Colorado...Oconee Colorado...and the 
remainder of our NE Georgia counties. These areas have the lowest ffg 
values as well as greater potential for upslope enhancement. Maximum 
temperatures will continue to be below climatology...similar to Saturday. 


On Monday the trough will lift northeastward across the area...and begin to 
merge with a larger scale shortwave entering the upper Mississippi 
Valley. The influence of the trough on lift will be lesser...and 
profiles are less conducive to heavy rain production. However 
isolated flooding cannot be ruled out. Probability of precipitation in general will be lower 
particularly over the southern half of the County warning forecast area. Despite less cloud cover 
and precipitation...temperatures may be slightly cooler due to lower thicknesses 
beneath the trough. So values still top out a category or two below 
climatology. 


&& 


Long term /Tuesday through Friday/... 
as of 130 am Independence day...heights start to rise Tuesday as 
upper low is absorbed into the northern stream and subtropical ridge 
regains strength over the southeast. Midlevel lapse rates accordingly 
weaken from day to day...so diurnal convective potential will return 
to near climatology...with mainly just showers mentioned. As a shortwave 
moves across Ontario/Quebec a cold front will sag into the Ohio Valley 
Wednesday...with high pressure building eastward behind it. The presence of this 
feature limits our confidence going forward. It is a seasonably weak 
boundary...however global models hint that a wave will develop along 
it somewhere to our west...though they differ in the details. GFS/Gem 
depict the wave tracking along or north of the Ohio River...mainly 
keeping the front on our northwestern fringe. The ec on the other hand 
develops a stronger wave over the Southern Plains...leading it to delay 
its push across the mountains until Friday. However this also implies a more 
bullish front. Will bring probability of precipitation back up slightly Thursday and Thursday night. 
Temperatures will warm back to near normal by Wednesday. 


&& 


Aviation /08z Saturday through Wednesday/... 
at kclt...VFR conditions will prevail through the period with the 
exception of possible rounds of convection leading to restrictions 
this morning...and again this afternoon. Stalled boundary in the 
vicinity of the Carolinas continues to yield an unsettled pattern 
with scattered rain showers/thunderstorms and rain favored. Thus...the taf initializes dry 
under scattered middle to broken high clouds and modest SW winds. Weather is 
introduced by morning as latest cam guidance favors upstream 
convection advecting over the Piedmont...hence a vcsh with a 4hr 
tempo for thunderstorms and rain. Winds will also increase out of the west-southwest at that 
time with gusts as high as 20-25kts possible during the 
morning/afternoon. Prob30 for thunderstorms and rain will prevail for the afternoon 
hours as chances drop off slightly...however remain at warranted 
levels. Conditions will improve into the early evening where scattered 
middle clouds and high level clouds prevail. 


Elsewhere...similar to that of kclt above where multiple rounds of 
rain showers/thunderstorms and rain are forecast at all sites on Saturday. The greatest chance 
will remain over the mountains/foothills where kavl/khky receive 
prevailing rain showers with thunderstorms in the vicinity mentions. Although chances are slightly 
lower across the upstate per guidance...latest radar trends favor 
better coverage through middle morning therefore also prevailed rain showers 
and thunderstorms in the vicinity at the SC sites. Restrictions are possible amongst any 
precipitation...however tafs only feature MVFR at khky/kavl per 
guidance. Otherwise...increasing SW winds at the SC sites will lead to 
yet another windy/gusty day with gusts as high as 25-30kts 
possible. Into the afternoon hours...shra/vcts or prob30s for thunderstorms and rain 
are featured at all sites to account for any convective activity. 
Expecting conditions to improve into the early evening as stated 
above. 


Outlook...precipitation coverage will remain high through 
Sunday...then the pattern will transition to a more diurnal 
pattern...but with continued moisture in the area. Restrictions will 
be confined mainly to thunderstorms and then early morning stratus 
where heavy rain fell the previous day.
