NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Raleigh NC 
955 am EDT Tuesday Aug 4 2015 


Synopsis...an area of low pressure will track from near Myrtle 
Beach northeastward along the southern Outer Banks of North Carolina 
through tonight. Meanwhile... a cold front will approach from the 
northwest and settle into North Carolina on Wednesday. 


&& 


Near term /through tonight/... 
as of 955 am Tuesday... 


Forecast is in good shape. Latest surface analysis shows surface low 
pressure off the northern SC coast poised to move to the northeast today 
near the southern NC coast and southern Outer Banks. A rather impressive 
shield of convection accompanies this low... and some of these 
elements have spread northwestward into the southeast County Warning Area. This behavior is 
expected to persist through today... resulting in scattered showers 
and storms over the southeast coastal plain east of I-95. This is in 
line with nearly all coarse and hi-res guidance including the Storm Prediction Center 
sseo... NSSL WRF... and ncar ensemble output. Subsidence on the west 
side of this formidable low should help temper much of the 
convection more inland (nw of a Fay-Wilson line)... however farther 
northwest over the northwest and far northern Piedmont... sheared vorticity spreading 
east-southeast from NE/IA/MO convection into the broad base of the mean 
longwave trough will spread into eastern Kentucky/Tennessee and western Virginia/NC later this 
afternoon through evening... likely instigating isolated to 
scattered convection along either an old outflow and/or the baggy 
Piedmont trough... although as was the case yesterday... entrainment 
of dry air within the below-normal-pw environment persisting over 
the western Piedmont of NC will limit coverage/strength/lifetime of any 
such convection. The hrrr and ncar ensemble probabilities bring this 
convection into our northwest County Warning Area around middle afternoon... with a slow 
southeastward drift and eventual dissipation by middle evening... in 
line with the current forecast with only minor tweaks needed. 
Aforementioned subsidence should prompt good heating particularly 
over the southern and eastern Piedmont and western sandhills (away from the 
coastal cloud shield)... and highs in the middle-upper 90s appear 
attainable there... with low-middle 90s elsewhere... coolest in the 
extreme east-southeast County Warning Area. -Gih 


Previous discussion from 335 am: 
a 1011 mb surface low centered just south of kchs is forecast to 
track northeastward generally along the coast of the Carolinas 
through tonight. Deep convection has blossomed during the past 
couple of hours in association with the low...and extrapolation of 
this activity (and the track of the surface low) suggests it should 
remain confined from Sampson and Wayne counties and especially 
points eastward...in axis of focused 925-850 mb moisture transport 
to the east of an inverted trough axis from the low center. 


Otherwise...a Piedmont trough will sharpen this afternoon...ahead of 
a cold front that was analyzed this morning from the lower Great 
Lakes to the lower Ohio Valley. The models indicate the cold front 
will settle south across Virginia tonight...to near the NC border by Wednesday 
morning. Will retain a 20-30 percent chance of a late afternoon and 
evening storm from activity that could either develop in-situ in vicinity of 
a Piedmont surface trough and/or that is more likely to initiate 
upstream over the NC/SW Virginia Mountains and in vicinity of the aforementioned 
front...which would then propagate away from those forcing 
mechanisms and into the NC Piedmont late this afternoon and evening. 


Strong diurnal heating of a deeply mixed boundary layer...and 
associated steep low level lapse rates and 25-30 c dewpoint 
depressions...would support a conditional risk of strong to damaging 
downburst wind gusts if convection indeed develops over or 
propagates into...central NC. However...middle level flow at this 
latitude/over central NC will remain only modest to the south of the 
main belt of westerlies at the base of a broad trough centered near 
James Bay...so any severe occurrence should be isolated. 


High temperatures near or slightly above those of Monday given a slight 
uptick in forecast low level thickness values - upper 80s/around 90 
where clouds should be most prevalent from kctz and kgsb and points 
eastward...to 90-98 degrees elsewhere...hottest from afp to Fay. 
Lows generally 70 to 75...after any convection that does occur moves 
east and/or dissipates by late evening. 


&& 


Short term /Wednesday and Wednesday night/... 
as of 350 am Tuesday... 


While the cold front will settle south across central NC and serve 
as a possible trigger for convection again Wednesday afternoon and 
evening...generally westerly flow aloft -including a significant 
downslope component at 850 mb- and veered surface flow into a pre- 
frontal trough that the models indicate will have drifted into the 
coastal plain...should generally limit coverage. Any scattered or 
widely so storms that do form...however...would again pose a risk of 
strong evaporatively-enhanced wind gusts. Weak cold air advection north of the 
boundary will take the edge off of the heat across the northern 
Piedmont...where lower 90s are expected...versus middle to upper 90s 
once again over the southern Piedmont and sandhills. Slightly cooler 
and less humid as the front settles to the near the SC border by 
morning...with lows in the upper 60s to around 70 degrees. 


&& 


Long term /Thursday through Monday/... 
as of 410 am Tuesday... 


The cold front forecast to be near the NC-SC border Thursday morning 
will meander back to the north on Thursday...as a wave of low 
pressure tracks from the middle-Mississippi River valley region toward 
the Ohio Valley region in response to a shortwave moving east from 
the central rockies. There are still significant model differences 
in the amplitude/timing the system that result in below average 
forecast confidence for late week. 


The NAM and European model (ecmwf) seem to be more consistent in showing a deeper 
disturbance and and noticeably stronger surface low that tracks just 
north of central NC late Thursday into early Friday...while the GFS 
shows a variety of disturbances in west-northwesterly flow aloft 
that eventually evolve into a deeper shortwave trough crossing our 
region late Friday. Will continue best chance probability of precipitation Thursday evening 
through Friday afternoon given the aforementioned consistencies in 
the European model (ecmwf) and NAM...though the best coverage may ultimately end up 
to our north with the retreating frontal zone. While the strongest 
middle-level westerlies will reside to our north during this 
period...the amplitude of the disturbance depicted in the European model (ecmwf) 
(albeit impacting the area at a poor time diurnally) and the 
presence of the frontal zone suggest a severe threat isn't out of the 
question. The trailing cold front will then cross the area by Friday 
evening...ushering in some drier air and leaving most of the County Warning Area dry 
as the focus moves toward the coastal area for the weekend 


The combination of cloud cover and periods of showers/storms should 
lead to highs a below normal by Friday....remaining at or just below 
normal Saturday before slowly trending warmer early next week 
beneath renewed northwesterly flow aloft. 


&& 


Aviation /12z Tuesday through Saturday/... 
as of 800 am Tuesday... 


Moist southerly low level flow on the north-northeast periphery of an area of 
low pressure near the central SC coast this morning will maintain 
scattered to broken IFR-MVFR range clouds at rdu/Fay/rwi...which 
will lift and scatter to VFR between 13-16z. While an isolated to 
widely scattered storm will be possible at all sites in advance of 
an approaching cold front late this afternoon and evening... 
particularly from int/gso to rdu...an axis of more numerous showers 
and storms will develop and affect the eastern Carolinas...including 
Fay and vicinity...beginning as early as this morning...before 
diminishing by this evening as the low passes by to the east. 


Aside from a small chance of a shower/storm Wednesday-Wednesday night... 
generally VFR conditions are expected through mid-week. A frontal 
system will cross the middle Atlantic region and result in a peak in 
the probability of showers and storms...and sub-VFR conditions...NC 
late Thu-Fri.
