Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
337 AM EDT Thu Oct 31 2019
.SYNOPSIS...
A strong cold front sweeps across the area from the west this
afternoon and evening with heavy rainfall and strong to severe
thunderstorms possible. The cold front will push east of the area
tonight. Behind the front high pressure will usher in much cooler
and drier conditions, with temperatures falling below freezing
across the mountains Friday night. Cool and dry conditions will
persist through the weekend and into early next week.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 330 AM EDT: A very active day with regard to severe
weather and localized heavy rainfall is still expected across the
western Carolinas and northeast Georgia today. Then, windy
conditions and freezing temperatures will be a concern in mountains
tonight. The setup early this morning includes a deep plume of
moisture feeding into the forecast area from the western/central
Gulf of Mexico. A closed low pressure system emerging from the
Plains is pushing into the Midwest, and the associated surface cold
front is racing eastward through central TN and western AL. Closer
to home, any remnant of a wedge frontal boundary continues to lift
northward early this morning, with improving southerly flow now
reaching the I-40 corridor. Any vestige of a surface stable layer
should quickly wrap north of the area through daybreak. Shower
coverage should blossom again from the southwest through daybreak.
Conditions will deteriorate quickly today as the approaching cold
front reaches the southwest mountains by Noon, moves east into the
foothills in the early to middle afternoon, and then races through
the I-77 corridor late in the day. Upper jet divergence will
increase sharply over the cold front, with the associated strong
forcing overcoming any limitations from the modest mid-level lapse
rates. Expect the southerly low-level jet to easily reach 50 kt by
mid-morning, and then stay around 50 or better through the afternoon
hours until the front arrives. Model consensus surface positive
bouyant energy runs about 1000 to 1500 J/kg ahead of the cold front
this afternoon, especially in the eastern half, and deep-layer bulk
shear values should reach 50 kt. Some 30 to 40 kt of bulk shear
could be concentrated in the lowest 1 km, especially across the
western NC foothills and piedmont, and the latest Day One Slight and
Enhanced Risks look well-placed. Damaging wind gusts will be the
primary threat with the main, solidifying convective line this
afternoon, but a few tornadoes will be possible. Regarding heavy
rainfall, the current, limited Flood Watch looks well placed given
the expected fast movement of the main convective line this
afternoon. No changes are planned for the Flood Watch.
The cold fropa will usher subfreezing 850 mb temps in quickly across
the mountains by 00Z this evening, with freezing temperatures
arriving rapidly at the surface overnight. An NC mountain/GA
mountain freeze warning will be posted for tonight, with
frost/freeze products then discontinued across the mountains on
Friday. Northwest flow upslope moisture will also wring out some
snow showers at the higher elevations tonight before drying up
quickly toward daybreak Friday. Will limit any dustings of snow late
tonight to the highest ridgetops of the Smokies and around Mount
Mitchell/Beech Mtn tonight. Finally, the gradient in the cold
advection flow will be strong enough to warrant a Wind Advisory in
the northern NC mountains, with winds ramping up after sunset
tonight and diminishing slightly toward daybreak Friday.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
As of 335 am Thursday: As the period begins on Friday morning,
the upper low responsible for the active weather across our area
on Thursday will be rapidly departing the northeast U.S. as a
shortwave trough digs into the Great Plains underneath a
developing longwave trough. The trough axis will propagate east
in progressive fashion through the period, and the attendant
reinforcing cold front will have zero opportunity to tap into
any moisture as it approaches our area Saturday afternoon. The
front should clear our area early Saturday night with another
high pressure center building into our area to end the period
Sunday morning.
Therefore, with no moisture to work with, the main weather story
for the short-term will be the cooler temperatures resulting
from the initial cold-air advection behind the first front and
a reinforcing shot of cold air behind the second front Saturday
night. Expect highs to be a solid 7-9 degrees below normal
on Friday and 6-8 degrees below normal on Saturday. With high
pressure building in on Friday, expect surface winds to weaken to
light and variable if not calm and set us up for widespread frost
potential Friday night into Saturday morning east of the mountains
as low temperatures should bottom out between 33-38 degrees over a
large portion of the Piedmont and Foothills. While mountain low
temperatures for Friday night will be a bit warmer than Thursday
night's lows (near freezing), the second frontal passage later
Saturday will usher in a new round of CAA and lows Saturday night
should drop several degrees below freezing again for the mountains,
with widespread 33-36 degree lows east. However, winds may be a
bit elevated Saturday night behind the front and frost development
may be more confined to sheltered areas.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 335 am EDT Thursday: Model guidance is in fairly good
agreement regarding a broad longwave trough over the majority of
ConUS into early next week, with divergence developing between
the GFS and the ECMWF/Canadian solutions heading into Tuesday
due to differences in the handling of southern stream energy.
The EC/Canadian camp phase the northern and southern stream jets
across the Lower Mississippi River Valley, producing enough
lift over persistent surface ridging to cause isentropic showers
over the area Tuesday into Wednesday whereas the GFS remains
dry due to a lack of forcing. Either way, we are not expecting
significant impacts with this energy. There is a bit better
agreement that another cold front will approach the area towards
the end of the period late Thursday into Friday with another
interaction of northern and southern jet streams across the Ohio
and Tennessee valleys, but again, the pattern remains fairly
zonal and without significant amplification, we are not
concerned about appreciable moisture flux and any significant
rainfall. Therefore, a comparatively quieter week ahead is
expected at this time.
Sunday afternoon should have our coldest high temperatures, maxing
out about 6-8 degrees below normal with surface high pressure
centered near our area. Sunday night into Monday morning, lows
will once again range from 33-36 degrees east of the mountains,
but winds should be light or calm, suggesting better potential for
widespread frost when compared to Sunday night. Thereafter, as the
high pressure center moves offshore, we remain within a weak ridge
but lose our cold air source and winds gradually veer to southerly
by late week. Therefore, highs gradually moderate to near normal
if not 1-3 degrees above normal Wednesday through Friday.
&&
.AVIATION /08Z THURSDAY THROUGH MONDAY/...
At KCLT and elsewhere: Shower coverage should be sufficient to
carry categorical light rain showers across the terminal forecast
area this morning in the very moist airmass ahead of the approaching
front over central TN. With any residual surface stable layer
gradually scattering out in the improving southerly flow, anticipate
mainly MVFR to low end VFR visibility this morning, but with IFR to
LIFR cigs being fairly persistent. The IFR ceiling restrictions will
persist through much of the day despite the breezy to windy
conditions developing as the front pushes in the from the west this
afternoon. KCLT will see the best chance of MVFR cigs before the
convection arrives. Expect robust SSW to SW wind gusts throughout
ahead of the cold front. Vsby reductions to IFR will occur mainly in
the heavier showers and thunderstorms. Will also feature afternoon
PROBs for TSRA and strong wind gusts around the time of arrival of
the main convective line just ahead of the cold front. Conditions
will improve rapidly to VFR with the fropa this evening, and gusty
winds will continue as they shift to W or NW.
Outlook: VFR conds with lighter winds are expected to prevail Friday
through much of the weekend. Overnight mountain valley fog each
morning may be the exception.
