Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
235 PM EST Fri Jan 4 2019
.SYNOPSIS...
Heavy rainfall will continue to exit the area as a low pressure
system pulls away from the southeast. Dry high pressure will spread
back over the region this weekend and linger into early next week.
&&
.NEAR TERM /THROUGH SATURDAY/...
As of 225 PM EST: Regional radars show the advancing rain shield
moving east across the I-77 corridor this afternoon. Cellular
elements are redeveloping across northern GA and eastern TN and
scattered coverage of slightly better rates will be possible over
our area through early evening as the upper low approaches the
southern Appalachians. Will pare Anderson County out of the Flood
Watch, but keep locations from Pickens north and east in the Watch
as streams continue to rise in these areas and we're seeing
intermittent rain showers as well. Expect an early cancellation in
these areas as well at some point this evening.
Otherwise, a mid-level dry slot wrapping into the region from the
southwest will steadily diminish PoPs through the early evening
hours. However, there remains a small chance of a few convective
elements over the southern piedmont and southwest mountains late
this afternoon as the frontal system approaches and with strong 850
mb flow remaining backed well east of the closed low advancing
across AL/TN. Will keep an isolated thunder mention in for these
areas, but the chance of anything strong looks remote. The lingering
surface wedge should scour and retreat northward tonight.
The H5 closed low will reach the Smokies this evening and then
translate across western NC overnight. the lifting low moving east
of the area will herald the onset of very strong cold advection
winds overnight into Saturday morning, as well as falling snow
levels across the NC mountains. The current thinking is that any 1
to 2 inch snow accumulations will be confined to the higher ridges,
generally above 4500 feet. Regarding winds, although the NAM
features some 50 to 60 kt of 850 mb flow late tonight, the
GFS/RAP/GEFS mean are all somewhat less, and mixing will likely not
tap into the more damaging winds aloft. An advisory seems prudent
for most of the NC mountains and one will be posted overnight
through Saturday for all of the central and northern NC mountains,
and for elevations above 3500 feet in the southern NC mountains.
Mountain wave cirrus may set up tonight and linger well into
Saturday. This could have modest impacts on maximum temperatures,
especially across western NC. The pressure gradient will relax very
slowly through Saturday afternoon, but with gusty conditions
throughout as mixing develops Saturday morning, especially across
western NC. Will keep the NC mountain advisory going all day given
the mixing, but it can probably be cancelled by mid to late
afternoon as the gradient starts to weaken.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
As of 2pm EST Friday: By Saturday evening, region will see continued
drying in northwesterly flow behind system that brought significant
rainfall on Friday. Sunday and Monday will see the development of an
upper ridge over the central CONUS on Sunday that propagates to the
East Coast by Monday evening. Passing of this ridge will give quite
fair and warm conditions Sunday and Monday with high temps as much
as 20 degrees above normal on Sunday. Bias correction on guidance
is running around minus 6 degrees, which I reduced to 3 degrees for
the official forecast as the upcoming weather pattern is somewhat
different than the recent history that bias correction is based on.
By Monday evening, next upstream system begins to affect the
Southern Appalachians with some Gulf moisture being drawn into the
area ahead of a broad region of low pressure. This leads to some
light showers as early as Monday evening in the mountains. Also on
Monday, surface high associated with migrating upper system, reaches
areas east of the CWA, with some northeasterly CAD flow developing
along the foothills, which could give some cloudiness and reduce
Monday highs to 5 to 10 degrees below those of Sunday (though still
well above normal).
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As of 2pm EST Friday: Round of what looks like fairly light
rain primarily over the mountains and foothills on Tuesday/Wednesday
provides the only precipitation for the Tuesday through Friday
period. As a couple upper waves pass by well north of the area
Tuesday and Wednesday, a cold front with some Gulf moisture ahead of
it crosses the CWA by Tuesday evening. Dewpoints increase about 5
degrees on Tuesday with this moisture, but, despite forcing from
cold front, moisture is limited enough that rain will be mostly over
the favorable upslope portions of the mountains and possible some
into the foothills; with precipitation generally less than a tenth
of an inch. Temperatures are expected to remain warm enough that
snow will only be possible at the higher elevations. With passage of
front on Tuesday, area will dry considerably with some cold
northwesterly advection behind the front. Dewpoints plummet back
into the 20s by Wednesday with temperatures dropping through the end
of the week. This will be the driest air the area has seen in recent
weeks, and may usher in a more seasonal regime. The EC model
generally agrees in broad trends with the GFS guidance through
Thursday, with both models showing a trough to the East and ridging
over the central CONUS Thursday morning. EC differs in having the
eastern ridge quite a bit stronger, with more cold advection and
drying Wednesday through Friday than seen in the GFS model.
&&
.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
At KCLT and elsewhere: The onset of southerly winds will soon mean
slow, gradual improvement in foothill and piedmont ceilings, but
this will likely take until the frontal system scours the low level
moisture from southwest to northeast this evening. Until then,
expect mainly IFR, with occasional LIFR, along with slowly
diminishing shower coverage. ENE winds in the wedge layer will give
way to gusty S to SW winds as the wedge front retreats and then more
westerly flow with time. KAVL will see a sharp switch to NW flow
this evening, with robust gusts of 20 to 30 kt developing and
possibly even some 30 to 35 kt early Saturday during the peak of the
cold advection behind the departing low. All locations east of the
mountains will see WSW to WNW flow with gusts at times as mixing
improves Saturday morning. Expect VFR conditions overnight through
Saturday, but with lingering or redeveloping MVFR at KAVL overnight
with NW flow moisture in place.
Outlook: Drying westerly and northwesterly flow will develop and
persist late Saturday, with VFR conditions and dry weather lasting
through the weekend into early next week. A swiftly moving front may
cross the region Monday night, but with very small chances of any
associated restrictions.
