JPTWhat forecasters said that day
The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before this river flood warning went out at Feb 10, 10:42 PM EST, 26 minutes earlier.
Area forecast discussion, Feb 10, 10:42 PM EST, 26 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
1042 PM EST Sat Feb 10 2018
.SYNOPSIS...
Strong southerly flow continues to transport deep Gulf moisture
over the region through Sunday as a slow-moving cold front
approaches eastern Tennessee. Heavy rainfall is likely as the
front approaches the mountains tonight and Sunday. Precipitation
chances will continue into the early part of the work week as the
front is slow to depart the region.
&&
.NEAR TERM /THROUGH SUNDAY/...
As of 1030 PM EST: The southern Appalachians are still on the
eastern edge of a large rain shield that extends from the Mid-
Atlantic to the central Gulf. Meanwhile, a TMB/wedge front is
slowly lifting north across the Piedmont, and seems to be a
focus for some intense showers. They are small and moving enough
that they shouldn't pose any excessive rain concern. Rain is
adding up in the SW Mountains, with gauges reporting 1-2" in the
last 24 hours. Stream gauges are beginning to rise, but are not
approaching flood stage at this time. See Hydrology section
below for more information.
So with all that said, the forecast is on track, and only minor
adjustments were made.
The overnight continues with light to moderate rain as a frontal
zone approaches from the west and keeps deep sw/ly flow aligned over
the FA thru the near term. A good connection to GOM and even Pac
moisture is noted in Sat loops which have increased PWATS to well
abv normal levels. There will be periods of upper vort energy
crossing the area throughout the night and into tomorrow which will
enhance precip rates and aide in producing deep convective cells.
In fact...soundings indicate a measure of elCAPE increasing
overnight with sbCAPE developing tomorrow as sfc temps rise abt 10
degrees abv normal in continued llvl wwa flow. So...very high amnts
of available moisture will be aided by isent lift and thermo/dyno
forcing. Thus...the flood watch still looks good and will not adj in
placement or time.
As for rainfall amounts...went with ens and op blends as the various
op models have varying ideas with placement and amounts of QPF. The
fcst still favors the SW NC mtns and NE GA where arnd 2-3 inches are
possible thru Sun. The models continue to advance heavier precip
bands east as well over the srn NE GA counties and the Upstate...so
rainfall totals have been bumped up in these areas as well. All in
all...it looks like areas along and north of the I-85 corridor will
receive the brunt of the precip and this will be the area of concern
for flooding issues beginning during the overnight period over the
far wrn zones.
There is a chance of strong to even a couple severe thnderstorms
tomorrow afternoon with differential heating and an increase in
sbCAPE possibly co-joining with stg deep layered shear. A QLCS type
line is not out of the question. Min temps will be non/diurnal with
lows likely occuring at the beginning of the tonight period or 23z.

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
As of 210 pm Saturday: The leading edge of a slow-moving frontal
zone should be draped across the southern Appalachians at the start
of the period, with frontal circulation and upper divergence in the
right entrance region of an upper jet max providing the main sources
of lift. Duration-type flooding issues may be ongoing across
portions our mountains to start the period, while lingering weak,
but positive buoyancy could result in scattered thunderstorms/heavy
rain showers, with a potential for localized flash flooding,
especially with any cells training ahead of the boundary and/or
along terrain features. Nevertheless, guidance does not offer any
consensus on the potential for weak surface waves to focus any
organized areas of heavier rainfall Sunday night. Assuming this is
the way events pan out (which would be a rather bold assumption in
this pattern), rainfall outside of any areas of deep convection may
be somewhat muted Sunday night/early Monday.
Pops remain in the likely-to-categorical range through much of
Monday, as the front is not expected to see much forward momentum
through our area until later in the day/Monday night. At that point,
sprawling 1040+ mb surface high pressure building east of the
central and northern Appalachians will allow much cooler/drier air
to funnel southward east of the mtns, pushing the front back-door
style through the forecast area by Tuesday morning. Deeper moisture
will begin shunting south and east of the area by this time,
allowing for a gradually diminishing pop trend such that rain
chances are slight chance at best by the end of Tuesday. However,
ample low level moisture should linger north of the boundary on
Tuesday, resulting in wedge-like conditions, with cloudy skies,
below-normal temperatures and perhaps some pockets of drizzle.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
As of 245 PM Saturday: The guidance remains in general agreement
that the upper pattern remains relatively flat and nearly zonal over
the southeastern CONUS keeping stronger northern stream short waves
near the Great Lakes while the center of the subtropical ridge moves
from the Gulf of Mexico into the Atlantic through the period.
However, there are some detail differences. The GFS is a little
stronger and farther south with a wave that moves through on
Thursday. It is also a little stronger and farther south with a wave
on Saturday. These differences show up at the surface as well. Any
lingering isentropic lift diminishes Tuesday night with diminishing
precip chances and an eroding cold air damming high. A weak cold
front approaches the area Wednesday night and crosses the area on
Thursday on the GFS while the ECMWF keeps it off to the west.
Another cold front approaches the area on Friday on the GFS while
the ECMWF brings keeps the original front in place but shows waves
moving along the front slowly inching it toward the area. The GFS
moves the front into the area Friday night and to the east on
Saturday while the ECMWF brings the front into the area Friday night
but stalls it just to our south as a wave along the front keeps
moisture over the area Saturday with a CAD high building in from the
northeast.
Given these differences, have gone with a model blend for the
forecast. This keeps any small PoP limited to the mountains for
Tuesday night and Wednesday, spreads higher chance PoP across the
area Wednesday night into Thursday, then has varying amounts of low
end chance PoP for Friday and Saturday. Needless to say, this is a
low confidence forecast given the detail differences. Temperatures
remain well above normal through much of the period, but do drop
down toward normal for Saturday.

.AVIATION /04Z SUNDAY THROUGH THURSDAY/...
At KCLT and elsewhere: Very moist atmosphere in place with
southwesterly upglide flow will continue to keep low cigs and
widespread showers around the area tonight thru Sunday. There is a
boundary setting up just southeast of the Upstate and KCLT sites
that has been drifting north. Some improvement in vsby and cigs may
occur if the boundary manages to cross over the sites. This is in
effect part of a shallow wedge erosion. By daybreak Sunday, guidance
shows all sides on the warm side of the wedge with IFR to MVFR cigs
and generally MVFR to VFR vsby (except in SHRA). There is also a
little more instability Sunday aftn for TS, but confidence is still
too low to mention in the TAF sites for now. Winds are still light
and favoring a NE direction within the wedge, but should turn out of
the S and increase (helping keep vsby up a little). Some gustiness
is expected on Sunday, especially at KCLT. KAVL is tricky due to the
downslope SW flow keeping conditions MVFR. Guidance wants to sock
KAVL back in overnight, partly due to the greatest coverage of
precip expected over the mountains. For now, will prevail MVFR with
tempo IFR.
Outlook: Some worsening of restrictions expected Sunday night, then
improving conditions are expected on Monday. However, moist cold air
damming will likely keep restrictions around into Tuesday.

.HYDROLOGY...
Across the North Carolina mountains, soil moisture values
and streamflows are near normal to above normal across most
of the area, with some exception across the extreme southwest
mountains. However, the somewhat drier antecedent conditions
across the southwest mountains will be quickly overcome by
anticipated rainfall. Reservoir pools are at or above target
levels as well so storage will be limited. Therefore, given the
primed antecedent conditions, runoff will be significant and the
likelihood of isolated to scattered small-stream flooding remains
high, especially across the southwest and southern mountains. Minor
mainstem flooding is most likely across the favored upper reaches
of the French Broad River, and remains possible along the Pigeon,
Nantahala, and Tuckasegee Rivers. While rainfall tonight will be
very efficient given near-record moisture content, heavy rainfall
totals will occur over a time period generally not conducive to
flash flooding, which occurs within 6-hours from rainfall onset.
Nevertheless, small-streams will respond fairly quickly to any
locally intense rainfall that develops.
Across the Foothills and western Piedmont of the Carolinas and
northeast Georgia, soil moisture values and streamflows have made
significant recoveries with recent rainfall, eliminating lingering
dry conditions and increasing the likelihood of significant runoff.
Where bands of heavy rainfall can set up across these regions
through early Monday, isolated to scattered minor small-stream
flooding is possible. Mainstem river flooding is less likely,
but cannot be ruled out, especially along the Saluda, Reedy,
and upper reaches of the Middle Tyger River.

conditions across the area, see http:/weather.gov/gsp/floodoutlook.
