What forecasters said that day
The local office's own words before this winter storm watch 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 winter storm watch went out at Feb 5, 10:12 AM EST, 1 hour 37 minutes earlier.
Area forecast discussion, Feb 5, 10:12 AM EST, 1 hour 37 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
1012 AM EST Fri Feb 5 2021
.SYNOPSIS...
A cold front will move east of the area today. Dry high pressure
will briefly tonight but with an unsettled pattern returning for the
weekend. Dry high pressure builds back into the area on Monday.
Unsettled weather possible through the rest of the week.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 955 AM Friday: The last of the precip is still moving across
our far SE zones, but should end once the cold front pushes farther
east by late morning. Weak high pressure will build in from the west
during the day and decreasing clouds will lead to peeks of sunshine
for the afternoon and early evening hours. Clouds have already
started breaking down across the western zones where the fropa has
occurred. With low-level CAA filtering in behind the front, expect
winds to pick during the day. This will provide the area with some
gusty winds, especially over the higher terrain, but is expected to
remain at sub-advisory level.
The front may not clear the region by much given that the frontal
boundary may get hung up in deep layer WSW flow as a broad trough
axis persists back over the central CONUS. Nevertheless, a brief
period of dry weather today and tonight to go along with westerly
downslope warming should permit max temps to surge to near or
slightly above climo east of the mountains. Expect min temps to
be near climo Friday night.
&&
.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
As of 330 AM EST Friday: Guidance coming into better agreement on
the overall pattern for this weekend. A short wave moves toward the
area Saturday and across the area Saturday night. The wave moves
east of the area Sunday with zonal flow developing Sunday night.
This wave induces cyclogenesis near the Gulf Coast along the tail
end of the frontal boundary that moves through the area today.
Moisture increases ahead of this low and moves into the area from
the southwest. Moisture and forcing maximize Saturday evening as
upper divergence moves in along with the short wave and the low
passes by to the south. Have increased PoP to high likely to trend
toward the guidance consensus. Although the pattern is looking more
Miller A, the developing CAD is more in situ type and p-type looks
to be messy more like a Miller B. There will also be a warm nose
moving in from the south. Naturally, partial thicknesses and thermal
profiles differ with each model. The NAM has the strongest warm nose
along with a decent barrier jet keeping a cold nose in place just
above the surface. The GFS takes a little longer for the warm nose
to develop, but it is very deep when it does. Have gone with a
guidance blend for thermal profiles using a Top-Down methodology for
p-types. This shows mainly rain along and south of the I-85
corridor, although sleet or even snow could mix in at onset as often
occurs. Sleet and snow would develop north of there with more sleet
where the warm nose is stronger and snow where it is weaker.
Accumulations will be highly dependent on the warm nose and surface
temps. A slight variation in either would cause significant
differences. For now, show no significant freezing rain. Snow/sleet
accums would be highest across the northern Blue Ridge Escarpment,
with some accums across all the mountains, even in the Upstate and
NE GA. Light accums would also be possible across the NC Foothills
and NW Piedmont. Given the ongoing Winter Weather Advisory, will
hold off on any product issuances for now to avoid confusion. If
these trends continue, then products will be needed.
Precip tapers off quickly Sunday morning as moisture and forcing
move quickly east with the departing low pressure system. A brief
period of light NW flow snow will linger near the TN border, but no
significant additional accums are expected. Dry conditions expected
Sunday night. Highs will be a little below normal Saturday and
Sunday, but possibly near normal outside of the mountains. Lows will
be near normal Saturday night then below normal Sunday night.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 245 AM EST Friday: Guidance still shows a general zonal upper
pattern over our area with a series of weak short waves passing
through the flow. Strong upper lows remain over the Great Lakes or
the Rockies. Big detail differences remain in the guidance surface
patterns and resulting sensible weather over our area. The GFS and
Canadian favor a weaker mid week system while the ECMWF is stronger
and much wetter. Monday looks to be dry before moisture increases
Tuesday or Wednesday. The GFS being weaker has some light, generally
rain, Wednesday. The ECMWF is much wetter, also generally rain, on
Tuesday. There could be a brief period of NW flow snow behind each
of these systems. The GFS is then wetter on Thursday with a weak but
farther north low pressure system. The ECMWF is suppressed and dry.
Again, the GFS is generally rain but possibly changing to snow over
the high elevations at some point Thursday or Thursday night. Have
gone with a guidance blend for PoP but capped it at low chance given
the model differences. Used a guidance blend for temps as well,
which gives near normal temps for Monday, rising above normal
Tuesday, falling toward normal Wednesday, then below normal
Thursday. Of course, this is all subject to change given the
differences and low forecast confidence.
&&
.AVIATION /15Z FRIDAY THROUGH TUESDAY/...
At KCLT and elsewhere: Rain is gradually coming to an end at all
terminal sites as the cold front continues its march over the area.
Expect the rain to completely shut off once the frontal boundary
passes over the area during the mid-morning hours. Cigs have been
teetering between VFR/MVFR, but has recovered to VFR where the
frontal passage has already occurred. Drier air will filter in once
the front makes a full passage and winds will back to the W/NW. CAA
will allow for an uptick in winds during the day, which progged
gusts to enter all TAFs during the afternoon and early evening hours
before subsiding around sunset. VFR conditions will prevail through
the rest of the TAF period after the frontal passage, but
flight restrictions will return fairly quickly later Saturday.
Outlook: Brief drying returns tonight into Saturday, but with high
uncertainty developing regarding restrictions Saturday night through
Monday. There is some chance of a wave and moisture moving east
along the stalled front to our southeast and bringing precipitation
and restrictions back into the area the latter half of weekend. Any
drying early next week may be short-lived as well.
