NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Raleigh NC 
321 am EDT Sat Aug 23 2014 


Synopsis...a cold front will move south through the state Saturday 
night into Sunday. High pressure will then build south into the 
region for early next week. 


&& 


Near term /through Sunday/... 
as of 315 am Saturday... 


Today and tonight: northwest to north-northwest middle level flow will 
continue across central NC this morning and today... yielding a 
continued threat of disturbances aloft tracking across central NC. 
Meanwhile... a weak surface trough will slip to the south of central 
NC this morning... yielding generally a light northeast to northerly 
surface flow across the area today. However... the main surface 
front is expected to remain to the north of the area through at 
least this afternoon/evening. Given all of this... expect mostly 
cloudy to overcast skies today... with scattered showers and storms 
today (possibly numerous)... most during peak heating aided by the 
approaching surface front. This should help to hold temperatures down some 
from yesterday for most locations. Thus... will show high temperatures 
ranging from the middle 80s NE to lower 90s SW. With respect to a severe threat 
today... given the expected cloud cover and continued general 20-25 
kts of deep layer shear expect any threat to be very isolated. Both 
the GFS and NAM show the best instability across the southwestern 
half of the County Warning Area (generally in the 1000-1500 j/kg range... surface 
based)... and thus would expect this location to be most favored for 
a strong to severe storm or two. However... given the probability is 
rather low we are not even outlooked in the day one convective 
outlook from Storm Prediction Center. Heavy rain will be a threat with the strongest 
convection as precipitable waters are forecast to remain near 2 inches. 


Main area of convection is forecast to begin pushing to the south of 
the area by this evening... while the low level frontal zone begins 
to move into the area. This should yield a continued low end chance 
of at least some showers though. With a low level east to 
northeasterly flow tonight... low stratus is apt to develop... with 
patchy light drizzle even. The main push of the cooler air should 
hold off until after daybreak Sunday. Thus... expect low temperatures will 
be in the upper 60s to lower 70s. 


Sunday: surface high pressure will continue to build into the area 
on Sunday... along with drier air aloft. This will yield much drier 
conditions on Sunday... with skies becoming partly sunny by 
afternoon. High temperatures will be cooler... around 80 northeast to middle 
80s south/southwest. Can't rule out some light showers in the east 
to east-northeasterly low level flow in the morning to early 
afternoon though. 


&& 


Short term /Sunday night and Monday/... 
as of 306 am Saturday... 


Surface dry Air Ridge extends southward into NC from a parent high 
positioned over northern middle Atlantic. This surface ridge supported 
aloft by a building upper level ridge...stretching from the middle- 
lower MS valley northeastward into New England. Northeasterly low level flow will 
advect cooler drier air into central NC. This drier air will aid to 
diminish any residual stratocu. 


Low level thicknesses drop to values 15-20m below normal for late 
August. This yields maximum temperatures of near 80 across the far north-northwest to 
low/middle 80s far south. Min temperatures Sunday night low-Maryland 60s. 


&& 


Long term /Monday night through Friday/... 
as of 306 am Saturday... 


Monday night through Thursday...tranquil weather pattern will 
continue. Upper level ridge will remain highly amplified until late 
Wednesday into Thursday at which time a short wave in the northern stream 
will be exiting the northern plains into the Great Lakes. The 
approach of this system will weaken/suppress the upper ridge 
southward. Associated surface ridge will maintain a dry weather regime 
with moderating temperatures through Thursday. Maximum temperatures Tuesday 
near 80 north to lower 80s south warm to the middle-upper 80s by 
Thursday. Min temperatures also gradually modify...from the upper 50s-lower 
60s Tuesday morning to the middle 60s Thursday morning. 


Forecast confidence wanes Thursday into Friday as GFS is much faster 
with the approach of the northern stream short wave toward the East Coast 
versus the slower European model (ecmwf). Also of concern is the eventual track of 
the tropical system that is expected to track parallel but offshore 
of the southeast U.S. Coast. Latest model guidance (mainly ecmwf) has 
shifted a little more to the west...with major timing differences 
(ecmwf much faster compared to the gfs). With the tropical system 
offshore and a trough in the vicinity of the Great Lakes/middle MS 
valley...would expect a narrow ridge over the Carolinas. Until the 
differences are resolved...favor a warm and mainly dry forecast for 
the end of the work week. Have warmed temperatures into the middle 80-around 
90 for maximum temperatures Friday while decreased rain chance to slight chance. 


&& 


Aviation /06z Saturday through Wednesday/... 
as of 155 am Saturday... 


24-hour taf period: isolated to widely scattered showers continue to 
move through central NC this morning... with the strongest 
convection located across western and southern portions of the area. 
Thus... expect kfay/kgso/kint will have the best chance at seeing 
some convection over the next several hours. However... krdu and 
krwi could see some of this activity too... but more in the 08/09z 
to 13z time frame. IFR/MVFR conditions will be possible with any 
showers and/or storm this morning. Given the subtle disturbances 
aloft moving across the region... skies have generally remained 
mostly cloudy to overcast (vfr though... lots of middle and high 
clouds). Thus... we have seen less in the way of sub-VFR visbys/ceilings 
develop this morning. Still think the best chance of seeing some sub- 
VFR conditions will be at krwi. Thus... will still show some sub-VFR 
conditions possible... mainly during the pre-dawn hours this morning 
at krwi. 


Greater convective coverage is expected later this morning into the 
afternoon as a series of upper level disturbances track S/south-southeast across 
the Carolinas and a back door cold front/pre-frontal trough 
progresses towards central NC from the N/NE. Thus... will add a probability- 
30 group to the tafs for storms this afternoon into the early 
evening at all taf sites. 


Outlook: IFR ceilings will be possible in the wake of the backdoor 
cold front tonight through middle-day Sunday...though coverage and 
duration remain a bit uncertain. An upper level ridge centered in 
vicinity of the southern Appalachians should result in better-than- 
normal chances for VFR conditions Mon-Wed...though a persistent east/NE 
low-level flow may allow adequate moisture for low-topped shower 
activity...especially at the eastern terminals (fay/rwi). 


&& 


Rah watches/warnings/advisories... 
none.
