NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
1004 am EDT Monday may 4 2015 


Synopsis... 
high pressure will remain across the region through the middle of 
the week. A weak cold front is expected to drift down from the north 
on Thursday. For the late part of the week...uncertainty is high as 
low pressure may move up the southeast coast and over the Carolinas. 


&& 


Near term /through tonight/... 
as of 10 am...conditions across the region remain clear with light 
southwest winds. I will update the forecast to reduce sky cover and 
populate temperatures/dewpoints with observations. The temperatures heading 
into this afternoon appear on track. I will delay Ridgetop 
convection by one to two hours based on 12 ffc sounding and latest 
runs of cams. 


As of 630 am EDT Monday...current forecast remains on track therefore no 
significant changes made/needed to the forecast. Did adjust 
temperatures/dews over the next few hours to account for recent trends. 
Expecting middle level cloudiness to dissipate this morning as primary 
500 mb wave exits east. However...low level cumulus will prevail by late 
morning as lapse rates steepen in the moist planetary boundary layer. 


Previous discussion... 


As of 315 am EDT Monday...the pattern aloft continues to feature a 
broad Flat Ridge over the southeast Continental U.S....while a weak 500 mb impulse 
slides through the mean flow over the southern Apps as evident on 
recent WV imagery. At the surface...high pressure centered off the 
NC coastline continues to rotate leading to weak south-southeast flow over forecast 
area. This pattern will prevail through the period with only slight 
modification to the surface high expected as it slowly slides 
further out to sea. Guidance continues to favor convection across 
the high terrain of western NC this afternoon/evening with the 
nam12/cams being the most aggressive. In addition...00z arw/nmm 
products indicate some convection over the NC/SC Piedmont...into 
portions of northeast Georgia. Soundings due indicate some instability in 
the low/middle levels...however within very shallow moist layer beneath 
middle/upper warm nose. 


Thus given recent days lack of verification of the higher res 
guidance...leaned on the low end of guidance as it pertains to probability of precipitation this 
afternoon. This yielded isolated/scattered rain showers and or thunderstorms and rain over 
the mountains...with probability of precipitation sharply tapering to non mentionable levels 
over the Piedmont and northeast Georgia. Lack of present triggering 
mechanisms was the leading factor in keeping probability of precipitation out of the lower 
terrain locations...while deeper moisture and possible upslope 
forcing could promote initiation over the mountains think any thunderstorms and rain that 
does occur will feature primary threats of cloud to ground lightning 
and brief heavy rainfall. Otherwise...partly/mostly cloudy skies 
will prevail as cumulus develops with peak heating this afternoon. Highs 
will top out in the lower 80s outside of the mountains...while the higher 
terrain reaches into the 70s for most locations. Conditions will 
improve through the evening with heating loss...thus all probability of precipitation are 
removed around midnight. Patchy fog could occur on Tuesday morning 
in and around the mountain valleys...especially if/where any daytime 
precipitation has occurred. Lows overnight will remain at or just 
above normal regionwide. 


&& 


Short term /Tuesday through Wednesday night/... 
as of 215 am Monday...the short range still looks relatively 
uneventful...as an upper ridge slowly amplifies over the region on 
Tuesday and Wednesday even as an upper low organizes and moves north 
along the Florida/Georgia coast. The pattern supports weak surface high 
pressure across the region through the period. A weak surface boundary gets 
strung out to the north and probably will not be able to make it this 
far S through Wednesday night. The models have latched onto this idea 
that mainly diurnal showers/thunderstorms will form across the 
higher terrain both days. While the forecast generally follows that 
plan...with a slight chance/chance each afternoon/evening...my confidence 
is probably not as high as the forecast might suggest. Thus far...the 
models have been overdeveloping the afternoon convection over the 
mountains the last few days. On Tuesday and Wednesday...buoyancy is not 
really all that great. Low level moisture convergence is not 
impressive. Backward trajectories each afternoon suggest that the 
mountains remain isolated from any real moisture source. This suggests 
that the amount/extent of precipitation in the models over the mountains might be 
overdone. Temperatures were generally nudged a bit warmer through the period 
thinking that we will be drier than indicated. 


&& 


Long term /Thursday through Sunday/... 
as of 315 am Monday...the medium range looks more interesting and 
more uncertain in light of the 00z run of the GFS...which wants to 
take low pressure of sub-tropical origin onshore of SC on Thursday 
and then westward Thursday night before stalling inland on Friday. 
If this development were to pan out...we would certainly need to 
raise precipitation chances considerably late in the week. Fortunately...a 
peek at the 00z run of the European model (ecmwf) will keep US from making those 
changes just yet...as that model keeps the upper/surface low offshore 
through the period. Few changes were made as a result. Precipitation chances 
were raised slightly on Thursday...which shows the most Promise for 
some convective activity with a weak front drifting into the 
vicinity...but mainly to come more in line with neighbors and the 
latest guidance from HPC. After that...the European model (ecmwf) suggests more of 
the same...with weak high pressure and an upper ridge...and the 
region still cut off from any moisture transport from the Gulf or 
Atlantic. Temperatures should be slightly above normal. 


&& 


Aviation /14z Monday through Friday/... 
at kclt and elsewhere...VFR conditions will prevail through the 
period as high pressure dominates. Earlier low/middle level ceilings have 
eroded and or spread out...thus prevail few/scattered at all sites in lieu 
of ceilings...except at kavl. Light/calm winds increase out of the south-southeast 
around to 6-8kts by late morning as the mixed layer 
deepens...however with no gusts expected. Still expecting 
increasing lapse rates to yield modest low level cumulus development with 
peak heating this afternoon. Continued to keep all sites dry 
through the afternoon with the exception of thunderstorms in the vicinity mention at kavl 
where instability will be maximized. 


Outlook...isolated to scattered diurnal convection is expected 
through Thursday...mainly over the mountains...as moist southerly flow 
persists.
