NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
142 PM EDT Wednesday Apr 1 2015 


Synopsis... 
surface ridging will prevail on Wednesday ahead of increasing 
precipitation chances on Thursday as moist southerly flow returns. 
Another cold front will push through northeast Georgia and the 
western Carolinas on Friday evening ahead of drier high pressure for 
the weekend. Moisture will return for the start of the next work 
weak as southerly flow once again commences over the region 
therefore increasing precipitation chances. 


&& 


Near term /through tonight/... 
as of 1205 PM...clear conditions prevail across the western 
Carolinas and northeast Georgia as of midday. Temperatures will maximum out a little 
above climatology this afternoon mainly over the western portion of the 
forecast area. Current grids are in good shape but made some minor 
adjustments to winds/dewpoints primarily for fire weather. 


As of 915 am...made some adjustments to temperature trends. Otherwise...the 
current forecast looks on target. 


As of 630 am...after a near miss from the northern extent of the decaying 
precipitation associated with the convection moving across Georgia...we 
should remain dry this morning. Still a very small chance of a shower 
developing over the lakelands/Savannah River basin with the front 
drifting S across that region...but it will not be included in the 
forecast. Temperatures continue to run warmer than forecast...giving US a bit of a 
milder start to the day. 


Over the next 24 hours...a progressive upper pattern will see the 
upper trough axis move eastward out over the western Atlantic...and an 
upper ridge building eastward over the Appalachians/western Carolinas. 
Weak high pressure will build in from the middle-Atlantic region behind 
the front this morning. High temperatures should be on the order of five 
degrees cooler than yesterday with the subtle air mass change. The 
upper ridge axis will move east across the region late tonight and 
that should push the surface high offshore...setting the stage for 
moisture return after midnight. A dampening short wave riding up the 
ridge will approach from the west after 06z Thursday and will bring 
some Gulf moisture with it...while the flow around the departed 
surface high will allow some Atlantic moisture to return as well. 
Prefer the slightly less enthusiastic precipitation development of the GFS 
near the Blue Ridge west of I-26 around daybreak Thursday...as it seems 
the model guidance develops the upslope precipitation a bit too fast. Will 
cut down the precipitation chances a bit. Min temperatures should be at or above 
normal. 


&& 


Short term /Thursday through Friday night/... 
as of 300 am EDT Wednesday...the short term forecast period initializes 
Thursday morning amidst short wave ridging aloft over the southeast 
Atlantic coast...while region of height falls approaches from the 
west. At the surface...high pressure will be in control of the 
pattern across northeast Georgia and the western Carolinas...however 
quickly retreating out to sea as a warm front approaches from the 
southwest driven by potent southern stream upper wave and associated 
surface cyclone over the Central Plains. A northern stream upper wave 
will be sliding through the northern Great Lakes with a surface 
trough/front stretched to the south along the Mississippi River 
valley. Models continue to agree on improving warm air advection regime with 
dewpoints surging across the southern Apps through the day on 
Thursday. Therefore the forecast features increasing probability of precipitation through 
morning across northeast Georgia...southwest NC...and the western upstate 
as upslope/upglide forced precipitation prevails early on ahead of 
maximum heating/instability. Probability of precipitation will then spread out further east as 
model soundings indicate modest/improving lapse rates aloft as the 
upper ridge shifts east...with steepening llv lapse rates with 
heating and moisture influx. Soundings also indicate some 
directional sheer in the profile Thursday afternoon/evening across 
these zones with approx 30km bulk shear present...however speed 
shear looks to be lacking as no primary low level jet/mlj is present. All 
said...would not be surprised at all to see a few deep/organized 
thunderstorms with hail/damaging winds being the primary threats as 
fz levels remain below 10kft. 


Beyond that...southerly upslope flow will veer southwesterly 
somewhat and weaken into the overnight hours. This combined with 
heating loss warrants lowered probability of precipitation due to lack of any forcing in the 
return. On Friday southerly flow will continue...however according 
to model guidance...llv dry air from remnant 850 mb ridge over the Gulf 
will be entrained in the mean flow thus advecting a region of lower 
dewpoints northward. This drier air at the surface on Friday would 
be a substantial limiting factor for any convection ahead of the 
frontal passage Friday night. Thus...probability of precipitation actually lower to slight chance 
levels across the NC/SC Piedmont as soundings look rather 
unimpressive. Models continued to favor at least high end chance 
probability of precipitation over the high terrain thus that was accepted in the forecast. 
Meanwhile...a line of convection just ahead of the front will likely 
be marching east through the Tennessee Valley...eventually arriving into 
the western NC and northeast Georgia mountains by the 00z timeframe. 
Expecting this line to move through the region overnight...therefore 
likely probability of precipitation are feature over most of the forecast area with thunder 
mentioned. Due to the above mentioned stable airmass over the 
southern Apps...would not be surprised to see any strong/severe 
convection along this line to weaken as it enters the forecast area. By 
periods end Saturday morning...the primary upper trough axis will 
swing through thereby motivating the front along or just east of the 
Interstate 77 corridor. 


&& 


Long term /Saturday through Tuesday/... 
as of 345 am EDT Wednesday...the medium range forecast period 
initializes Saturday morning amidst a departing cold front and 
intruding high pressure beneath quasi zonal flow aloft. Mentionable 
probability of precipitation will be in the forecast initially...however will lower quickly to 
non mentionable levels by middle afternoon. Skies will clear out as 
the high builds in thus allowing for abundant sunshine amongst 
falling thicknesses. Temperatures on Saturday will be a few degrees 
under climatology...with slightly cooler temperatures prevailing on Sunday 
where frost conditions are possible over the mountains during the early 
morning hours. The surface ridge will migrate east into Monday allowing 
for the return of southerly warm air advection beneath continued zonal flow aloft. 
Modest baroclinic zone across the arklatex...east into the midsouth 
will build ahead of another potent cold front. Increasing moisture 
over the southern Apps Monday into Tuesday will yield reintroduction 
of chance probability of precipitation by Monday evening as upglide maxima region advects 
overhead along the western periphery of the departing surface 
ridge. Probability of precipitation will remain at low end chance levels on Tuesday as 
improving warm air advection regime yields dewpoints in the upper 50s to lower 60s 
thus providing ample moisture for convection. Temperatures on 
Monday will return to normal levels...with warmer temperatures forecast 
on Tuesday.

Aviation /18z Wednesday through Monday/... 
zczc gspwrktaf 011040 
ttaa00 kgsp ddhhmm 


At kclt...looks like VFR conditions will prevail through the taf 
period. However...moisture will increase across the area Thursday 
morning as high pressure moves well off the coast and Gulf moisture 
advects into the region. Looks like deeper moisture and best 
isentropic lift stays west of clt...so only lowering VFR ceilings 
are anticipated after 12z. Light NE winds will shift to southeast circa 
00z. 


Elsewhere...VFR conditions with light winds will hold for the 
overnight. Deepening moisture and isentropic lift will develop circa 
12z with VFR ceilings lowering to MVFR and even IFR at kavl by 
17z. The exception will be khky which should remain VFR. Scattered rain 
showers are also expected to be around the airfields after 12z 
except at khky. 


Outlook...moist southeast upslope flow will continue Thursday night 
into Friday morning which will promote MVFR to IFR ceilings. 
Conditions will improve to VFR by Friday afternoon. A cold front 
will affect the area Friday night into early Saturday...bringing 
another round of rain/possible thunderstorms and restrictions. VFR 
will return for the rest of the weekend.
