Area forecast discussion, Oct 7, 3:39 AM EDT, 6 hours 2 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
339 AM EDT Thu Oct 7 2021
.SYNOPSIS...
An upper level Low pressure over the lower Mississippi Valley will
focus a very moist southerly flow off the Gulf of Mexico into our
region for another day before it moves toward the Great Lakes.
Expect periods of widespread showers and locally heavy rainfall
through Friday especially for the mountains and foothills. As this
low and its associated front moves east of our area this weekend,
dry high pressure will be in place into early next week.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 335 AM EDT: A deep upper low will slowly move north from the
Mid-South into the Mid-West through the period. A series of short
waves will rotate around the low and across the area today. Much
weaker short waves are expected tonight. Good upper divergence
expected today as a jet streak rotates across the area. The
divergence weakens overnight as the jet streak moves away from the
area. Deep moisture remains in place over the area through the
period with PW values generally 1.5 inches or higher. Weak
instability remains in place as well along with good warm cloud
precip processes and isentropic lift. The one limiting factor is the
low level jet. While H85 winds will be southeasterly today, they
remain less then 30 kts. The synoptic and CAM guidance all respond
with widespread precip coverage over the western CWFA with lower
coverage over the east. The Flash Flood Watch looks well placed and
basically in line with QPF and Excessive Rainfall forecast from WPC.
That said, can't rule out flooding outside of the watch, especially
along the Upper Savannah River valley of the northern Blue Ridge.
Another warm and muggy day expected.
With forcing diminishing tonight as the upper low moves north,
expect precip coverage and intensity to diminish. This is in line
with both synoptic and CAM guidance. Deep moisture and weak upslope
flow will keep a chance of showers across the area overnight, but
the threat of new flooding greatly decreases. Therefore, the current
end time of the Watch still looks good. Will be another warm and
muggy night.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
As of 300 am Thursday: Arcing upper trough associated with filling
upper low/transitioning open wave over the Midwest at the start of
the period will push steadily through the forecast area Fri into Fri
night. With in-situ cold air damming likely all but dissipated
during that time and plenty of lingering low level moisture...part
of which will be supplied from easterly flow north of tropical
disturbance off the Carolina Coast. Numerous showers and scattered
storms are therefore expected to flare up once again on Friday,
warranting likely PoPs across the entire area. There will be a
continued threat of locally excessive rainfall, with local antecedent
hydro conditions likely being the primary driver of any developing
runoff issues on Friday.
With low level moisture continuing to circulate around the
disturbance off the coast, PoPs will linger across primarily the
eastern half of the area Fri night into Saturday, but with a gradual
draw-down in probabilities to less than 20% by Saturday evening. Min
temps will remain above climo through the period, while maxes will
steadily warm to the tune of a couple of degrees above climo by
Saturday afternoon.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 245 am Thursday: Establishment of a long wave trough across
the western Conus will result in downstream ridging over the East by
the early part of the medium range, and this regime is forecast to
more or less persist into the middle part of next week. This will
result in dry and unseasonably warm conditions through much of the
period, with temps likely averaging around 5 degrees above climo.
Additionally, dewpoints will be anomalously high for early/mid
October, and in fact, wouldn't completely rule out some spotty
diurnal mountain showers early next week. Overall, it's not going to
feel especially fall-like.
&&
.AVIATION /08Z THURSDAY THROUGH MONDAY/...
At KCLT and elsewhere: Despite some VFR across the area, expect
deteriorating conditions this morning as moist upslope flow
continues, along with copious low level moisture. Expect MVFR cigs
to become widespread with IFR/LIFR cigs by daybreak then continuing
through the morning. Expect MVFR vsby to develop across much of the
area with TEMPO IFR vsby in heavier showers. NE wind continues
through the morning, S at KAVL. Expect slow improvement to MVFR cigs
and VFR vsby in the mid-afternoon. Showers will continue through the
period, so have prevailing or VCSH continues. TSRA will be possible
during the afternoon, so PROB30s have been included for that. Expect
cigs to drop back into the IFR range during the evening with some
MVFR vsby. NE wind, S at KAVL, continues through the period.
Outlook: A wet pattern is expected to continue into Friday, with
occasional periods of widespread showers and frequent occurrence of
flight restrictions expected. Finally, some drier air will try to
work in from the west this weekend, but low-level moisture may
linger, keeping a chance of low cigs and fog, especially late
night/early mornings.
