NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
214 PM EDT Tuesday Jul 29 2014 


Synopsis... 
Canadian high pressure will dominate the surface pattern through 
midweek...leading to well below normal temperatures more typical of 
late Summer or early autumn. As the surface high weakens...moisture 
will return for the weekend increasing the chances of widespread 
showers and thunderstorms. 


&& 


Near term /through Wednesday/... 
as of 200 PM Tuesday...the afternoon forecast still looks on 
track...especially with the idea of minimizing the mention of any 
showers in the mountains. No echoes yet on radar and the Storm Prediction Center mesoscale 
anal Page still shows no SBCAPE. Hence...still think that current 
slight chance probability of precipitation over the highest terrain in the mountains will hold 
US despite the considerable quantitative precipitation forecast response in the 12z NAM and GFS. Any 
isolated showers that do develop should dissiapte quickly with the 
loss of heating. 


In regard to the big picture....the anomalous upper trough will 
remain in place over the eastern U.S through Wednesday. At the 
surface...cool high pressure will remain to the north of the region. 
These incredients will produce a cool night across the area for late 
July. In fact...our forecast is reflecting tying the record low for 
the date at avl which is 54 set in 1897. Elevations above 4000 feet or 
so will see lows in the 40s. Outside the mountains...lows will be 
mainly in the 60-65 degree range...except for some 50s in the NC 
foothills/northern NC Piedmont. No records outside the mountains 
appear to be in play tonight. The record low is 58 at clt/63 
forecast and 60 at gsp/62 forecast. 


Wednesday should be a similar day to Tuesday with partly to mostly sunny 
conditions. Forecast soundings are essentially capped so the chance 
of afternoon convection looks to be even lower on Wednesday. Will only 
increase probability of precipitation to slight chance over the SW mountains in the 
afternoon where models show some light quantitative precipitation forecast repsonse. Maximum temperatures will 
continue to be a couple categories below climatology. 


&& 


Short term /Wednesday night through Friday/... 
as of 145 PM Tuesday...the upper trough over the eastern part of North 
America will remain the dominant weather feature through the short 
range...but its evolution will have important consequences. The axis 
of the upper trough should be located over the middle-Atlantic and 
Carolinas on Wednesday night...but this will shift to the MS 
river/Great Lakes on Thursday in response to new short waves digging 
down into the trough. A weak 850mb low will also move west with the 
upper trough...and in doing so...the low level flow will come around 
to southeast for Thursday and Friday. Although the flow will be light and 
moisture transport will be weak...there should be enough moisture 
return to fuel an increase in shower coverage both days. Precipitation 
probability climbs up to the chance range mainly over the mountains and 
foothills for Thursday...and then solidly in the chance range for 
Friday. Bouyancy will also increase...so thunderstorms are possible 
again Friday afternoon. Not ready to jump into the likely range for 
Friday yet. The position and timing of a vorticity center moving through 
the region on the GFS is viewed with a suspicious eye at this time. 
Temperatures will remain below normal. 


&& 


Long term /Friday night through Tuesday/... 
as of 130 PM EDT Tuesday...the medium range forecast picks up at 00z on 
Saturday with the persistent upper trough axis over the Great Lakes 
and miss River Valley and upper ridging over the western Continental U.S.. the 
long range models suggest that the trough will begin to deamplify on 
Sunday and continue to lift through the rest of the period. This would 
result in a split flow pattern over much of the southeast region sandwiched 
between upper ridging to the west and the Bermuda high to the east. 


At the surface...deeper layer moisture is expected to be spread over the 
County warning forecast area by the start of the period and remain over the region through day 
7. By Sat evening...the bndy layer flow is expected to become more 
southeasterly and remain southerly to southeasterly for the remainder of the forecast period. 
Precipitation chances will remain good Thursday the weekend with probability of precipitation tapering 
off some for days 6 and 7 as some drier air could work its way in 
from the northwest. Temperatures should remain well below normal for early August 
with values expected to warm a few degrees by the end of the period. 


&& 


Aviation /18z Tuesday through Sunday/... 
at kclt...mainly broken clouds around 050ft this afternoon. They will 
become scattered late this afternoon. No visibility restrictions. 


Elsewhere...expect scattered-broken clouds at 040-050 feet through the 
afternoon. Clouds will become few-scattered late this afternoon. No visibility 
restrictions except at kavl where some light fog is expected early 
Wednesday morning. 


Outlook...high pressure will prevail into Thursday morning with the only 
possible restrictions being early morning fog/stratus in the 
mountain valleys. Moisture will be increasing during Thursday 
into Friday which will yield unsettled weather with enhanced 
precipitation/fog/stratus chances through the weekend.
