What forecasters said that day

The local office's own words before this red flag 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 red flag warning went out at Apr 9, 6:45 PM EDT, 1 hour 43 minutes earlier.

Area forecast discussion, Apr 9, 6:45 PM EDT, 1 hour 43 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
645 PM EDT Thu Apr 9 2020

.SYNOPSIS...
Cool and very dry high pressure will build over the region
through Saturday. A strong storm system with abundant moisture is
expected to affect our region on Sunday and Monday before cool high
pressure returns by the middle of next week.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 640 PM EDT Thursday: Warm, dry and breezy conditions continue
with humidities into the teens across many areas. Current fire
related products east of the mountains are well placed with no
changes anticipated.

Otherwise, a Red Flag Warning remains in effect for all SC counties
in our FA through 8 PM EDT. A Wind Advisory remains in effect for
portions of the NC mountains through 8 PM EDT as well. A Special
Weather Statement remains in effect for portions of the NC Piedmont
and northeast Georgia regarding the increased fire danger for this
afternoon.

With temperatures well above normal and plenty of sunshine in most
locations, conditions have been rain-free today with the exception
of showers and thunderstorms that moved through the area early this
morning ahead of a cold front. With the cold front continuing to
push into the eastern Carolinas, the main story for today has been
the gusty winds associated with this feature and the increased fire
danger risk given these winds and the low relative humidity. As
noted above, hazard products are in effect for these concerns.

For tonight, do anticipate quiet and dry conditions to prevail with
higher gusts subsiding as upper troughing to the north begins to
slowly drop southward, while shifting eastward as well. Latest
guidance continues to suggest a tightening pressure gradient across
the mountains before daybreak as the vort max drops into the area
(around 09-12Z). As a result, around round of gusty winds may be in
store for the mountains early on before expanding to the rest of the
area (though higher gusts will remain confined to the mountains). As
a result, a Wind Advisory may be needed. Min temperatures will be
around normal. Will note, some of the CAMs continue to suggest light
QPF across the extreme northern mountains late tonight, which with
temperatures below freezing could allow for isolated snow showers
(mainly Avery and Mitchell counties) before daybreak. Attm,
confidence remains low and do not anticipate any snow accumulations.

On Friday, dry conditions will prevail as upper trough shifts
eastward offshore and ridging begins to amplify to the west with sfc
high pressure slowly building in from the west. With the increased
NW winds and low relative humidity, do anticipate criteria to be
near or met for fire weather concerns. Thus, additional fire weather
hazard products may be needed for Friday. After a few days of
temperatures above normal, max temperatures on Friday will actually
remain below normal.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 220 pm Thursday: The short term will be a tale of two halves,
as the cool and dry weather of the late near term will extend into
at least the first half of the weekend. In fact, within a strong
radiational cooling regime, frost concerns will be on the plate for
Sat morning, mainly along the I-40 corridor in the Piedmont and
foothills. (The spring frost/freeze program is currently inactive
for the mountains). Frost is certainly not a slam dunk, as
dewpoints/RH will still be very much in recovery mode, but suspect a
Frost Advisory will eventually become necessary for all or a portion
of the northern NC Piedmont and foothills for Sat morning.

Otherwise, a split flow regime will be in place across the western
half of the country through much of the period, with northern stream
energy allowing a Four Corners upper low to kick out and open into a
neg tilted trough across the Arklatx by Sunday evening. Partial
phasing of the flow will yield deep S/SW flow/moisture return across
the Southeast Sunday, with warm frontal/upslope precip likely
developing across our forecast area during the afternoon. Potent
cyclone developing across the Mid-Miss and western Ohio
Valleys...tracking into the Great Lakes is expended to send a
strongly forced frontal zone into the western Carolinas and
northeast GA by Sunday evening, with plenty of model clues that a
triple point/sub-synoptic scale low will likely track across the TN
Valley/southern Appalachians. Considering that the Gulf of Mexico
will be wide open...supporting unseasonably high levels of moisture,
these factors would yield a heavy rainfall threat across the region
late Sunday into Sunday night. However, the threat for excessive
rainfall remains somewhat cloudy owing to recent dry conditions.

Perhaps of greater concern is the potential for high shear/low CAPE
severe convection, as guidance is depicting very high values of low
level shear (~50 kts 0-1 km) to go along with the strongly forced
frontal zone. The GFS advects a ribbon of positive sbCAPE (250-500
J/kg) into the Piedmont after 00Z Monday, which is certainly
adequate for severe/potentially tornadic convection in such a
strongly forced/sheared regime. SPC's Day 4 Outlook depicting an
area of 15% risk to coincide with this "ribbon" of sbCAPE therefore
is entirely reasonable.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 245 pm Thursday: After the fireworks of the late short term,
much of the medium range looks to be quiet and cool, as a broad/low
amplitude trough is forecast to become established across much of
the eastern half of the country. In fact, temps are forecast to be
around 5 degrees below climo through the period. The only potential
disruption to this regime will be a potential for light rain  during
mid-week, when global models depict a Miller-A cyclone developing
off the Southeast Coast. However, the ECMWF, which has been the
wettest model with this scenario for a couple of cycles now, is
trending drier with today's 12Z run. As such, only token small pops
will be carried across primarily the Piedmont during the mid-week
time frame.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
At KCLT and Elsewhere: VFR and breezy west to northwest winds are
expected to prevail through the TAF period. Lee troughing may
support winds backing to southwest at times east of the mountains,
especially between 15Z and 22Z Friday.

Outlook: Precipitation and flight restrictions return this weekend.
Otherwise expect VFR.

.FIRE WEATHER...
RH has crept below 25% this afternoon across much of the Piedmont
and foothills, while wind gusts of 20-30 mph are common. A Red Flag
Warning remains in effect until 8 pm for Upstate South Carolina.
Fire Danger statements are also in effect for Northeast Georgia and
the non/mtns of North Carolina. RH recovery will not be especially
significant tonight, generally remaining less than 50% in most areas
east of the mountains.

Winds will again be gusty on Friday, and if anything RH will be a
bit lower despite much cooler temps. After coordination with land
management agencies and neighboring NWS offices, Fire Danger
Statements will be issued for all NC and SC zones, but we will wait
until today's products expire before issuing tomorrow's. Further
coordination will be needed with Georgia users.

Winds will be much weaker Saturday, but min RH is nevertheless
forecast to be in the 25-30% range, possibly warranting a new suite
of Fire Danger Statements. Heavy rainfall is forecast to develop
across the area Sunday into Sunday night.
