NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Greenville-Spartanburg SC 
654 am EDT Friday may 29 2015 


Synopsis... 
Bermuda high pressure will persist across the region through the 
weekend and into early next week. Deeper moisture will gradually 
spread along the southern Appalachians within the southerly flow 
between low pressure approaching the middle Mississippi Valley from the 
west and the offshore Bermuda high to the east. A cold front will 
push southward into the region around middle week and then likely stall 
nearby. 


&& 


Near term /through tonight/... 
as of 650 am...I will issue a quick update to increase the mention 
of fog across the unifour and portions of the northern upstate. In 
addition...I will remove probability of precipitation through middle morning. Trends within the 
temperature...sky...and wind appear on track. 


As of 310 am...near term models indicated that an old sea breeze 
will remain over the Piedmont through sunrise. The position of the 
sea breeze should generally align along the I-85 corridor. Winds 
should remain calm to light south-southwest wind through the morning hours. High 
pressure centered over the western Atlantic and an elongated cold 
front across the central Continental U.S. Should result in southeast winds this 
afternoon and evening. As the winds shift this afternoon...the old 
boundary is expected to slide across the foothills and east facing 
mountain slopes. The combination of weak instability...higher 
dewpoints...and weak upslope flow should trigger scattered rain showers and thunderstorms and rain 
this afternoon into the early evening. The greatest coverage should 
occur over the NC foothills and northern mountains high temperatures are 
forecast to range at to slightly above normal. Forecast soundings 
indicate that storm motions should remain similar to values observed 
on Thursday. Therefore...we will highlight the potential for slow 
moving heavy downpours in the severe weather potential statement. 


Tonight...the forecast area will remain of the western edge of a 500 mb 
587 dm ridge...heights will begin to fall during the pre dawn hours. 
Mild middle level temperatures should result in steady stabilization 
after sunset. Any convection across the region should start to 
dissipate with loss of heating...I will indicate in the probability of precipitation. 
Overall...conditions will remain comparable to early this 
morning...light south to calm winds...waves of middle and high debris 
clouds...and patchy fog. Low temperatures are forecast to range from 
the low 60s within the mountain valleys to middle 60s east. 


&& 


Short term /Saturday through Sunday night/... 
as of 245 am Friday morning...the short term forecast picks up at 12z on 
Saturday with upper ridging lingering over the region and a low 
amplitude upper trough gradually making its way towards the County warning forecast area. Over 
the remainder of the period...the ridge axis slides farther off the 
East Coast while the trough axis is expected to be just to our west by 
early Monday. At the surface...the Carolinas will still be under the 
influence of the Bermuda high with weak southerly flow over the region. An 
elongated frontal zone with deep layer moisture will approach the County warning forecast area 
late Sat/early sun...however the models are slow to bring the moist 
air into the County warning forecast area. Its looking like the bulk of the deeper moisture 
wont spread over the area until the end of the period early Monday. 
Regardless...precipitation chances are minimal for Sat and considerably 
higher for sun. Surface based instability looks fairly impressive on Sun 
afternoon/evening with ample cape in the hail growth region. Shear 
and helicity are minimal...but we could certainly see numerous pulse 
type severe ts through the day on sun. Temperatures are still on track to warm a 
few degrees over the period with highs reaching the middle to upper 80s 
each day. 


&& 


Long term /Monday through Thursday/... 
as of 310 am Friday morning...the medium range forecast picks up at 12z 
on Monday with an upper trough axis just to our west and upper ridging 
to our east over the Atlantic. Over the next 48 hours or so...the trough 
axis will gradually slide over the Carolinas and then lift NE of the 
area while broad scale upper ridging begins to build in the troughs 
wake. At the surface...a large plume of deep layer moisture associated 
with a dissipating frontal zone will keep the forecast area under 
favorable conditions for widespread showers and ts on Monday and Tuesday. 
By Wednesday...some drying is likely...especially over the northwest zones as the 
deeper moisture moves farther east and the Great Lakes high slides 
farther southeast and sets up wedge type surface pattern over the forecast area. 
This wedge is expected to maintain itself through day 7. High temperatures 
will cool a few degrees Monday through Wednesday with values expected to warm 
again on days 6 and 7. 


&& 


Aviation /12z Friday through Tuesday/... 
at kclt...winds are expected to remain light to calm early this 
morning...as the terminal remains within the axis of a weak surface 
ridge. Based on surrounding observation...it appears that a period of MVFR 
ceilings may develop during the first one or two hours of sunlight. 
Otherwise...sky is forecast to remain VFR...with periods of scattered to 
broken clouds around 040 kft. MOS and near term models agree that winds 
should remain from the south-southwest through middle day...then turning from the 
south-southeast during the afternoon. The light southeast low level flow should favor the 
foothills and mountains for afternoon convection...I will keep the taf 
dry. 


Elsewhere...several of the terminals received measurable rainfall 
Thursday afternoon and evening. Areas with wet ground have resulted 
in the formation of fog and stratus before the release of the 12z 
tafs. At khky...I will mention LIFR visible and ceilings in the taf until 
VFR returns by kavl may keep light fog through 15z...then VFR. By 
the afternoon...low level southeast flow should bring a round of humidity across 
the southern Appalachians this afternoon. I will highlight the 
convection with afternoon prob30 for kavl and khky. Convection 
should dissipate short after sunset. 


Outlook...moist SW flow will continue to affect the terminal 
forecast area through this weekend...as a cold front lays over to 
the north of the area. Expect pockets of morning fog and/or stratus 
most days...with continued chances of afternoon/evening rain showers/thunderstorms and rain each 
day.
