NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
232 PM EDT Wednesday Sep 2 2015 


Synopsis... 
a weak pressure pattern will linger atop the region for the rest of 
the workweek. Late Summer warmth and daily thunderstorm chances will 
be the main features of interest. A back door cold front is expected 
to push across the region on Friday followed by a cool and moist 
area of high pressure this weekend. 


&& 


Near term /through Thursday/... 
as of 230 PM Wednesday...mean upper ridge will remain in place over 
the eastern half of the country. Our area is left in weak northwest 
flow aloft with intermittent shortwaves riding down the flow. One 
will dive down toward the Carolina coasts tonight...while another 
piece of energy from the lower Mississippi Valley will get picked up 
by the mean flow...traversing the Tennessee Valley and working its 
way toward the Carolinas early Thursday morning. This will bring 
with it some middle-level moisture that will serve to increase cloud 
cover overnight...thus keeping lows several degrees above seasonal 
normals. A very very weak surface boundary will push through 
tomorrow as well and despite surface winds shifting around to the 
northeast...seems slight to low chance probability of precipitation are warranted across the 
area tomorrow to account for the additional lift associated with the 
shortwave and front. Some weak orographic lift may serve to enhance 
convection especially across the southern mountains as well. Despite 
all this...highs will continue to hover above seasonal normals with 
low 90s across the upstate and Piedmont and 80s across all but the 
highest elevations of the mountains. 


&& 


Short term /Thursday night through Saturday/... 
as of 215 PM Wednesday...an upper level high will begin to 
strengthen over the northeast states...while a relative weakness 
will linger around its western and southern periphery...extending 
from the Ohio Valley to the southeast states. This will place the 
County warning forecast area within very weak middle and upper level flow through the short term. 
At the surface...high pressure will build over New England...ridging 
southwestward through the Carolinas. A weak back door cold front will 
push through Thursday night...with gradually increasing northeasterly 
to easterly low level flow Friday through Saturday. Guidance is in pretty 
good agreement on the flow transporting increasing low-middle level 
moisture. This combined with falling heights aloft should result in an 
increase in instability for Friday and Saturday. The easterly flow will 
also enhance upslope forcing along the Blue Ridge for lift. So I 
will forecast a shotgun chance pop on Friday...with slightly higher values 
in the high terrain...and solid chance to low-likely pop for Saturday. 
This is not much change from previous forecast. Friday still looks to 
see above normal temperatures...as thicknesses Don/T fall much until 
Saturday. More cloud cover and precipitation on Saturday will result in 
temperatures about a category below normal. 


&& 


Long term /Saturday night through Wednesday/... 
as of 100 PM Wednesday...the latest medium range guidance supports 
the going thinking of surface ridging continuing to nose sswd into the 
County warning forecast area through Sunday. The prognosticated pressure gradient looks similar to 
Saturday...but thinking clouds will be a tad thinner with maximum 
temperatures a hair warmer. With surface pressures forecast to rise on Labor 
Day Monday...progressively less cloud cover and maximum temperatures 
climbing toward climatology is expected. The inherited climatology range... 
diurnally enhanced deep convective chances will remain as is. 
Back to more typical late Summer conditions on Tuesday featuring 
temperatures and pop near climatology with an increase in return flow 
prompting greater thunderstorm chances for the new day 7. 


&& 


Aviation /19z Wednesday through Monday/... 
at kclt and elsewhere...surface high pressure will remain in control 
today...but a weak shortwave will drift from the southern 
Appalachians to the middle-Atlantic coast tonight...with another weak 
shortwave pushing across northern Georgia into South Carolina early 
Thursday. The two of these combined will allow for isolated 
convection to form this afternoon but not enough to mention in the 
tafs. Should see an increase in low VFR cloudiness especially 
overnight. West-southwest winds at taf time at all but kavl /NW there/ will 
veer and shift to west-northwest by 00z or so...and around to north /mainly calm/ 
overnight. Should not see any restrictions at the taf sites Thursday 
morning due to drier surface air building in. 


Outlook...a pattern of diurnal isolated/widely scattered showers 
and thunderstorms is expected to continue through the end of the 
work week. By the weekend...a moist easterly flow is expected to 
develop...bringing better chances for showers and restrictions. Low 
clouds and fog will be possible each night in the mountain valleys.
