Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
224 PM EDT Mon Jun 7 2021
.SYNOPSIS...
Daily shower and thunderstorm chances continue through the week as
an upper low meanders northeastward into the Great Lakes region
while the Bermuda High pumps Gulf moisture into the Southeast. Even
as this pattern breaks down late this week, showers and
thunderstorms will continue at least through Saturday.
&&
.NEAR TERM /THROUGH TUESDAY/...
As of 150 pm: Convection is blossoming across the forecast area
early this afternoon along the leading edge of deep moisture plume
extending from the Gulf of Mexico into the TN Valley and southern
Appalachians. Coverage should continue to increase as activity lifts
northeast across the CWA through the afternoon into early evening,
warranting 70-80 PoPs across much of the forecast area. Instability
is perhaps a bit higher than what was previously anticipated, while
shear values are at least approaching the moderate range, so there's
been a slight uptick in the chance for a pulse severe storm or two.
Meanwhile, slightly improved mean tropospheric flow is allowing for
better cell movement than during the past couple of days.
Nevertheless, the potential for training cells, continued very moist
conditions/warm rain processes, and increased overall convective
coverage than in previous days will result in a continued risk of
locally excessive rainfall. Convection should again steadily
diminish and/or move east of the forecast area this evening, with
token small PoPs retained through the overnight in light of the
moist environment. Min temps will again be several degrees above
climo.
In terms of the synoptic setup, just more of the same on Tuesday,
with upper low wobbling very slowly east across the central Conus,
and subtropical ridge east of the area supporting anomalously moist
conditions across the forecast area, although guidance indicates
some decrease in mean 1000-500 mb RH. Short term guidance also sets
up a weak surface trough across the forecast area, which could
provide a focus for diurnal convective initiation, in addition to
the usual terrain effects. Thus, another day of above-climo PoPs is
warranted, with 50-60% chances peaking during the late afternoon in
most locations. The threats for a brief pulse severe storm or two
and locally excessive rainfall will otherwise persist.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
As of 145 PM EDT Monday: Midlevel ridging persists through Wednesday
before weakening on Thursday as the upper low previously situated
over the Ozarks meanders northeastward. As it does so, it loses
much of its veracity and phases with a developing trough over
Canada, and with a fairly relaxed height gradient it will be tough
to get significant synoptic forcing. Meanwhile, at the surface,
southerly flow continues as a consequence of the stationary Bermuda
High over the west Atlantic. Late Thursday, the global models hint
that it will begin creeping southeastward, but this should not
hinder continued southerly flow from pumping Gulf moisture into the
low-levels. So, where earlier in the week profiles look to be near-
saturated through much of the troposphere, midlevels will begin to
dry out starting Thursday as mid/upper flow veers more west-
southwesterly. The area of 2"+ PWATs will push eastward
following the best synoptic environment, and our CWA will see
slowly diminishing PWATs after Thursday morning.
Nonetheless, we'll be looking at rain chances through end of the
short term - scattered showers all day Wednesday and into Thursday,
with the potential once again for some afternoon pulse storms in the
presence of modest surface instability. It's looking as though the
threat of heavy rain could continue into Thursday owing to
stationary storm cells, with PWATs lingering in the ~1.5" vicinity
and background winds struggling to pick up the pace. Luckily, in
line with what we've seen thus far this week and this past weekend,
the flooding threat should remain highly localized.
Temps should climb from at- or slightly above-normal on Wednesday,
to at least 2-3 degrees above normal on Thursday.
&&
.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
As of 200 PM EDT Monday: On Friday, the trough over the northeastern
CONUS prompts development of a weak low pressure system over the
Ohio Valley. The warm frontal boundary should keep well to our
north, though it should aid in maintaining PoPs late Friday and
early Saturday. A weak attendant cold front pushes through the CWA
on Saturday, and flow at least briefly turns northwesterly. The
approach of a second upper feature - a shortwave that attempts to
skirt the broader trough - complicates matters, potentially inducing
additional rainfall past Saturday. Models remain in poor agreement,
however - with the GFS and ECMWF pushing for more rain, while the
CMC allows the shortwave to simply fade into the background flow as
dry, high pressure filters into the CWA on Sunday. For now, have
kept chance PoPs in the grids through the end of the extended.
Highs should remain a degree or two above normal through Saturday.
They'll likely drop on Sunday behind Saturday's cold front, but
certainty is low for not on the details.
&&
.AVIATION /19Z MONDAY THROUGH SATURDAY/...
At KCLT and elsewhere: Convection is blossoming across the Terminal
Forecast Area this afternoon, and tempos for TSRA are warranted at
all sites. Coverage of convection should steadily diminish and/or
move east this evening, but coverage should remain high enough to
warrant VCSH through at least late evening. Statistical guidance is
in good agreement in developing widespread IFR, or even LIFR
conditions (primarily cigs) late tonight into early Tuesday, and
this trend is reflected in the latest forecast. Scattered convection
should begin firing by the end of this forecast cycle, and Prob30s
for TSRA are advertised at all sites during Tue afternoon.
Outlook: Scattered to numerous, mainly diurnal convective coverage
and associated restrictions persist through much of the week.
Morning fog/stratus are also possible, especially in the mountain
valleys.
