Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
329 AM EDT Fri Mar 22 2019

.SYNOPSIS...
Cool and dry high pressure moves over our region from the
Great Lakes today, and then moves off into the Atlantic late in the
weekend as a brief warming trend returns. An area of low pressure is
forecast to track across our area early in the week, bringing the
chance of rain and a few thunderstorms, then dry high pressure
returns for Wednesday.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 315 AM: The western side of a double-barreled 500 mb low will
dive southeast across the Central Appalachians today. This feature
will bring a second shot of strong CAA and increased nwly 850 mb
winds across the CWA today. Despite a modest 1025 mb sfc high
building in behind a departing coastal low pressure system, it looks
to be a breezy to windy day for the fcst area. Winds across the
Northern NC mountains will be close to the advisory criteria of 30-
40 mph and gusts of 45-60 mph, while the piedmont looks to have 15-
25 mph and gusts of 25-35 mph, esp across the NC zones. After
coordination with RNK, have opted to issue a Wind Advisory for the
Northern Mountains and adjacent escarpment zones for today through 6
AM Saturday. The winds combined with the mixing of dewpts down into
the 20s will result in low RH for most of the lower elevations,
which have fire weather impacts (see fire wx section below).
Otherwise, it should be sunny today (with some lingering stratocu
along the TN border thru late morning). Max temps will be a little
below normal, ranging from the 40s to upper 50s in the mountains and
in the 60s across the piedmont.

Tonight, the 850 mb CAA will continue, but overall winds should
gradually decrease---first over the piedmont in the evening, then in
the mountains overnight. Temps will be held up somewhat by the
mixing, but still should drop a couple categories below normal
(mainly in the 20s lower 30s mountains and mid to upper 30s
piedmont).

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
As of 245 AM EDT Friday: Overall fairly quiet through most of the
short term, with troughing down the East Coast pushing offshore and
giving way to ridging that will build into the area. High pressure
over the Midwest to start the period will work is way southeast and
offshore by Sunday morning. Pressure gradient will decrease and flow
will gradually shift back around to the south, so expect a gradual
warming trend through the period...and overall a very pleasant
weekend. The ridge amplitude will decrease as a trough moving off
the Rockies damps and lifts toward the Great Lakes through the
period. Some anemic moisture attendant with this system may move
into the mountains Sunday afternoon and evening, drying up as it
pushes east. A secondary shortwave will dive down behind the trough
Sunday night as a surface low over the Ohio Valley is forced
southeast, but best forcing with this system will hold off until
Monday.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 300 AM EST Friday: Approaching system will be on our doorstep
Monday morning, passing through the area during the day. Still some
timing differences with the global models on the frontal passage,
but the overall look of the system is fairly similar. By the time it
gets to our area, the shortwave will have weakened to the point that
deep-layer shear certainly leaves something to be desired, but there
might be enough airmass recovery ahead of the front, with afternoon
highs climbing just a hair above seasonal normals, that instability
is able to develop Monday afternoon and evening, possibly lingering
into the early overnight hours. SBCAPE values remain below about
750J/kg and generally below 500, so have continued the thunder
wording across most of the area, mainly along and south of I-40.
Moisture dries up fairly quickly but any lingering moisture at the
higher elevations around daybreak Tuesday may switch over to some
brief snow. GFS is a little faster with exiting the precip while
ECMWF holds onto it just a little longer, so a generic blend seems
to work for now.

Behind the front, should see temperatures knocked back down 10-12
degrees for Tuesday with dry high pressure stretching down the
Eastern Seaboard. Dry conditions with a gradual warming trend
through the end of the period.

&&

.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
At KCLT and elsewhere: The upper low will begin to slowly shift NE
of the area thru the period, keeping some low clouds and spotty
light SHRA/SN along the TN/NC border. The clouds continue to produce
cigs over KAVL, but elsewhere only a few stratocu thru the
overnight. Otherwise, it's mainly a wind fcst. A fairly tight
pressure gradient along with deep mixing will result in a gusty west
to northwest winds across the region, starting around 13-15z today.
Gusts of 25-30 kts expected for a few hours this aftn, before some
diminishing around sunset.

Outlook: Gusty winds will gradually taper off this evening.
Otherwise, expect VFR to prevail into the weekend. The next weather
system will affect the area by Monday, bringing some precip and
chances for restrictions at that time.

Dry and breezy to windy conditions will redevelop today, with RH
values generally between 25-30%, but some areas in NE Georgia will
drop below 25% RH. A Fire Danger Statement is in effect for NE
Georgia for this afternoon and early evening. Winds will diminish on
Saturday but dry conditions will continue, with more of the area
dropping below 25% (and NE Georgia will likely need another Fire

showers and a few thunderstorms possible on Monday.

...GUSTY NORTHWEST WINDS AND ACCUMULATING SNOWFALL POSSIBLE
ACROSS THE HIGHER ELEVATIONS TONIGHT...

Lingering moisture and the infiltration of colder air associated
with a cold front will bring the potential for rain and snow
showers along the higher elevations, especially above 3500 feet,
through the overnight hours. Additional snowfall amounts of up to
an inch will be possible, especially near the Tennessee border.
The potential exists for dangerous driving conditions across high
mountain roads due to the combination of snow and gusty northwest
winds of 20 to 30 mph, with gusts up to 40 mph.

...FIRE DANGER STATEMENT IN EFFECT FOR NORTHEAST GEORGIA FROM 2
PM EDT THIS AFTERNOON THROUGH THIS EVENING...

Relative humidity values will fall below 25 percent for several
hours this afternoon. The combination of low relatively humidity
values and low fuel moisture values will result in enhanced fire
danger this afternoon.

Please refer to your local burn permitting authorities on whether
you can burn today. If you do burn, use extreme caution since
fires can quickly get out of hand under these conditions.
