Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
251 PM EDT Mon Jun 11 2018

.SYNOPSIS...
A weak cold front is expected to move south across the region
tonight. Behind the front, Tuesday should be relatively cloudy and
not as warm. Typical summerlike conditions will return for Wednesday
through the weekend.

&&

.NEAR TERM /THROUGH TUESDAY/...
As of 245 PM EDT Monday: This update includes the discussion
for the 18Z TAFs along with the afternoon package update.

Mid-level cloud cover was more expansive through the morning hours
than previously anticipated across the western Carolinas and
northeast GA, making the temperature forecast a tricky one today.
With less cloud cover along the I-77 corridor, Charlotte ended up
being the warmest of the official climate sites today (currently 91
degrees), with temperatures elsewhere remaining in the upper 70s to
low to mid 80s. Expect this to hold true as cloud cover continues to
expand eastward. Though shower activity was previously confined to
the higher elevations along the TN border this morning, shower and
thunderstorm development has blossomed elsewhere within the last
hour, though will note activity is more widespread west, east and
south of the FA attm. With portions of a backdoor cold/cool front
continuing to drop into NC from the northeast along with a low level
boundary which has developed along portions of the NW Piedmont,
areas along and just east of the I-77 corridor as well as areas
across portions of northeast GA may be the areas that see the most
convective activity today, though isolated showers and thunderstorms
cannot be ruled out across the foothills into the Upstate. Though
instability is marginal, would not entirely rule out a severe
thunderstorm today as the area remains within SPC's Day 1 Marginal
Risk.

Once the front pushes through the FA tonight, instability will
become obsolete and sfc high pressure off to the northeast will
build in overnight and into Tuesday, allowing for a wedge front to
be the main weather pattern feature through the rest of the near
term forecast period. Increasing cloud cover tonight is expected to
persist through into Tuesday as the feature settles in, allowing for
overnight temperatures to remain above normal. Temperatures on
Tuesday will be cooler than today, anywhere from 5 to 10 degrees
cooler, with overall light northeast winds prevailing.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
As of 130 PM EDT Monday: Thanks to the progressive pattern,
weak sfc ridging nosed swwd into the cwfa will give to a broader
w to sw flow on Wednesday, with developing lee troughing.
Weakly cyclonic flow aloft will aid in diurnal deep convective
development, with coverage possibly becoming numerous in the
mountains. Maximum temperatures should bounce back to around
climo. The pattern atop the SE CONUS is progged to change little
through Thursday, featuring a weak westerly flow aloft and a
non-descript sfc pattern. Outside of making an upward
adjustment to inherited max temps, a pretty typical mid-June day
is expected featuring diurnally enhanced tstms.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
As of 200 PM EDT Monday: Mid level ridging will build across
the area during the middle of the week but westerly flow will
remain not far to the north. The ridging will strengthen over
the middle of the country by next weekend while a low develops
just off the mid- Atlantic region.

Fairly typical early summer conditions are expected as a result of
this pattern. Expect more coverage of diurnally enhanced showers and
thunderstorms for the middle of the week with the coverage being
less Friday through the weekend as the ridge asserts its influence.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
At KCLT and elsewhere: VFR prevails across the area this
afternoon with a backdoor cool front just to our northeast, and a
boundary across the NW Piedmont, which has allowed for winds from
KGSP/KGMU to KCLT to become more northerly over the past few hours,
while NW winds prevail elsewhere. Showers and thunderstorms are
beginning to develop across portions of the FA this afternoon,
mainly just east of the I-77 corridor, as well as along the NC/TN
border and across northeast GA. Though more cloud cover was in place
across the area this morning than previously anticipated, expect
isolated to scattered activity to grow and persist through the
evening hours. Thus, have kept VCSH/VCTS at all TAF sites this
afternoon and evening. Otherwise, expect VFR cigs to gradually
deteriorate to MVFR/IFR overnight as sfc wedge builds in across the
area with the parent sfc high pressure to the northeast. Isolated
showers and thunderstorms are possible on Wednesday as well, but
anticipate coverage to be less than today. Winds will become
northeasterly overnight with this feature (except for KAVL -
southeast) and prevail through the end of the valid TAF period, 3 to
8 kts.

Outlook:  Periods of showers and thunderstorms will be possible each
day, primarily in the afternoon, along with some fog and reduced
ceilings, primarily in the mountains.
