Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
1029 PM EDT TUE JUL 19 2016

.SYNOPSIS...
A weak front will stall out over the area tonight, bringing increased
chances for widespread showers and thunderstorms. The front dissipates
over the region tomorrow with subtropical high pressure building back in
for the rest of the week and early next week.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
As of 1020 PM, convection is confined to the I-77 corridor in NC
attm, with persistent but weakening strong to severe storm over
Rowan County, and additional cell development occurring along the
outflow spreading away from this cell. Pops have been increased to a
solid chance across these areas, including the SW Piedmont for the
next couple of hours. Once this activity weakens and/or pushes east,
the remainder of the overnight should be free of convection. Min
temps will be above normal, with the exception of the few pockets
that have been influenced by convective outflow.

The upper pattern will gradually amplify thru tonight with the large
and sprawling upper anticyclone over the Srn Plains and an upper
trof along the east coast providing a NNW flow. Not too much in the
way of mid/upper support in the big picture, and the models do not
show any upstream development that might send out an outflow
boundary that would impact our area. Thus, expect Wednesday to be
quiet relative to the past few days. Fcst soundings show some
instability atop a strong cap early in the day, but as temps rise
and the boundary layer deepens and moisture mixes out, most of that
buoyancy is eliminated.  That does not suggest much of a chance for
precip outside the mtns, so precip prob was kept at or below climo.
Temps should be very similar to today.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
As of 200 PM Tue: Expansive upper ridge will remain over the
southern Plains for the latter half of the work week, retrograding
bit as waves progress eastward in the northern stream. The Bermuda
High will remain the dominant feature over the Southeast coast,
though it is suppressed slightly as a trough settles over the
Northeast Friday. Low level winds will remain southerly, but
veer to SW over the course of the forecast period. Overall the
pattern looks routine for July, with PoPs forced by the diurnal
instability cycle, and t-storms remaining disorganized/pulsey on
account of small shear parameters. Temps will warm a bit further
Friday with an uptick in thicknesses, with maxes reaching category
or two above normal. Dewpoints appear likely to mix out enough to
keep heat indices around 100 at most during this period.

Latest NAM does not seem to be generating any MCS activity over
the Midwest Wed or Thu nights as it has on some previous runs,
but it is still not out of the question that such a storm could
develop and be carried into the upper TN Valley or southern
Appalachians. We'll keep an eye on the situation upstream.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
As of 215 PM Tuesday...the medium range fcst picks up at 00Z on
Saturday with broad upper ridging over the central CONUS and a
low amplitude upper trof digging down over northern New England.
Over the weekend, as the polar jet becomes more active and moves
farther south, the ridge gradually gets suppressed and heights
begin to fall. The period ends early next week with relatively
zonal flow over the SE region and the ridge persisting over the
Western CONUS. At the sfc, we still expect to be under the
prevailing Bermuda High for the whole period. This should keep
light, southerly flow over the region each day with near climo
summertime POPs and very warm temps. Heat indices climb to
advisory levels over much of the lower elevations for Saturday and
Sunday and get very close on Monday.

&&

.AVIATION /03Z WEDNESDAY THROUGH SUNDAY/...
At KCLT and elsewhere, VFR conditions are expected through the
period. The only convective mention this evening will be at KHKY,
where a cell currently about 20 miles north of the terminal may be
in the vicinity by around 01Z. Cannot completely rule out a shower
or storm in the vicinity of KCLT by late evening or so, but chances
are very low. Winds are generally expected to remain light NW, or
become light/vrbl this evening, then become light NE by tomorrow
afternoon. Chances for convection appear to be low again on Wed, so
no mention of convection tomorrow afternoon.

At KAVL, kind of a tricky forecast in terms of the fog/stratus
potential tonight, esp in light of the fact the there was none last
night. Very light precip fell at the terminal today and dewpoints
were several degrees lower than they've been in a few days. However,
the light up-valley flow and occl mid-level clouds that prevented
fog/stratus development last night is not expected to be as
prevalent tonight, and available guidance is quite pessimistic.
Opted to feature prevailing MVFR visby with a tempo for 2SM/FEW003
after 08Z. Otherwise, widely scattered convection should develop
across the area again tomorrow afternoon, supporting a PROB30 for
TSRA after 18Z.

Outlook: Expect fairly typical midsummer weather with afternoon
showers and thunderstorms during the middle and latter part of the
week. Morning fog and low stratus will be possible each day in the
mountain valleys and also in locations that received heavy rainfall
in the preceding afternoon/evening.
