BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
700 PM EDT TUE JUN 13 2017

The National Weather Service in Greenville-Spartanburg has issued a

* Flash Flood Warning for...
  Southwestern Cabarrus County in the Piedmont of North Carolina...
  Southeastern Mecklenburg County in the Piedmont of North
  Carolina...
  Northwestern Union County in the Piedmont of North Carolina...

* Until 1000 PM EDT

* At 656 PM EDT, Doppler radar indicated thunderstorms producing 
  heavy rain across the warned area.  Two to three inches of rain 
  have fallen in the past 1-2 hours.  Flash flooding is possible
  within the warned area over the next few hours.

* Media are already reporting flooded roadways, mostly due to
  poor-drainage, but the significant rainfall rates will overwhelm
  stormdrains and may flood area streams as well very shortly.

* Rapid rises on area streams and associated tributaries is likely, 
  including along: Mallard Creek, Reedy Creek, McAlpine Creek, 
  Little Sugar Creek, Doby Creek, Briar Creek, McMullen Creek, and 
  Fourmile Creek.

* Some locations that will experience minor flooding and may 
  experience significant flooding include...
  Uptown Charlotte, South Charlotte, East Charlotte, Matthews, Mint 
  Hill, Indian Trail, Weddington, Stallings, Harrisburg and Marvin.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Most flood deaths occur in vehicles. Do not attempt to cross
water-covered roadways, bridges, or low-level crossings. Only a few
inches of rapidly flowing water can carry away your vehicle. It is
not worth the risk. Please TURN AROUND, DON'T DROWN.

Excessive runoff from heavy rainfall will cause flooding in urban
areas. Storm drains, streams and other drainages will become
overwhelmed by excessive rainfall, flooding low-lying roads,
intersections, and parking lots. Underpasses are especially dangerous
because sudden flood waters can quickly surround and submerge your
vehicle. Stay alert and avoid flood-prone areas.

When it is safe to do so, please report flood waters or landslides
flowing over roads or threatening property to the National Weather
Service by calling toll free, 1, 800, 2 6 7, 8 1 0 1, by posting on
our Facebook page, or via Twitter using hashtag NWSGSP. Your message
should describe the event and the specific location where it
occurred, including roadways, nearby cross streets, stream names and
other landmarks.

What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before this flash flood warning went out at Jun 13, 5:55 PM EDT, 1 hour 5 minutes earlier.

Area forecast discussion, Jun 13, 5:55 PM EDT, 1 hour 5 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
555 PM EDT Tue Jun 13 2017

.SYNOPSIS...
Subtropical high pressure centered to our east will weaken through
mid week, allowing deep moisture to spread over the forecast area
from the south. Chances for showers and thunderstorms will increase
each day through the work week and remain elevated through the
weekend. A more well-defined cold front is expected to approach the
area early next week.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
As of 545 PM EDT: Updated the PoPs thru the evening hours to reflect
radar trends and also incorporate the latest CAMs. Decent SBCAPE of
2000-2500 J/kg combined with DCAPE of 800-1200 J/kg has been
supporting strong to severe storms across mainly the Foothills and
Piedmont. This activity should gradually diminish over the next few
hours as we are past peak heating.

As of 220 PM: The southeastern states remain under a broad upper
ridge, but a weakness exists in the form of a shallow sfc/upper
trough extending down the East Coast from a low over the Canadian
Maritimes. A small vort max is present over VA/NC as well. Despite
the enhancing effect of the trough, convection so far today has
been mainly associated with the high terrain. Steering flow is
weakly from the NW in this area, so it is logical that the model
consensus is for some of the activity to move off the ridges and
gradually into the Piedmont with time. Fairly high LCLs and DCAPEs
exist, and in light of weak shear these are marginally supportive
of severe downbursts, but so far no cells have had a sufficiently
strong updraft for such. Nonetheless, over the course of the aftn
outflow boundaries should focus new development. The suite of meso
models shows a couple hours' variation in how quickly things fizzle
out after the loss of heating. The NAMNest is on the faster side,
and its depicted coverage is verifying fairly well so far. However,
I am reluctant to trend PoPs down very quickly given the expectation
of lingering outflows. Some fog is likely to develop tonight in the
mountain valleys and where heavy rain falls this aftn...too early
to say with certainty exactly where. Profiles certainly are not
supportive of widespread fog so it should remain rather localized.

Heights continue to fall over the Mid-Atlantic as the aforementioned
shortwave/vort max shifts east, but rise a bit over us. The
low-level flow backs to NW as ridging tries to build in. Overnight
this NW flow could fire a few showers/storms near the Tenn
border, so a small PoP returns in the early morning up there. That
shortwave, in conjunction with continued westerly flow across the
Appalachians, appears to keep the trough in place for Wednesday.
Lapse rates will be modest and similar to those today. Hence
convective potential is similar as are PoPs. Modeled DCAPE values
however are notably larger which implies greater downburst risk
under still weak shear. SPC Day 2 outlook covers most of the CWFA,
excluding our southwest and far south, in a Marginal Risk area.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
As of 115 PM EDT Tuesday: Moisture, instability, forcing, and the
resulting convective coverage, will gradually increase Thursday
through Friday. As the upper ridge over the southeast starts to
break down on Thursday, upstream shortwave energy will stand a
better chance of reaching the southern Appalachians by peak heating
Thursday afternoon. Better upper-level troughiness will then develop
between the Mississippi River Valley and the Appalachians by Friday.
The pattern of mainly diurnal convection will continue during this
late week period, with a steady uptick in convective coverage and
intensity as lapse rates steepen a bit and surface-based CAPE values
reach 2000 to 2500 J/kg across more of the area. Flow up the column
will remain light through the period, but the boundary layer flow
will become more southerly with time. This will increase moisture a
bit as precipitable water values exceed 1.5 inches in the mountains
and approach 2 inches in southeast sections. This will increase the
localized heavy rain threat as well. Coverage should also become
more expansive outside of the mountains on Thursday and Friday
afternoons as west to southwest flow increases slightly aloft.
Expect overnight min temps at least two categories above climo, with
afternoon maxes at least a category above climo eacy day.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
As of 200 PM EDT Tuesday: The work week will end with a fairly weak
pressure pattern over the southeast as a wave rounding an upper low
centered over southern Ontario provides some weak upper level
forcing close to the spine of the Appalachians. This will aid the
development of mainly diurnally-driven showers and thunderstorms
Friday night. Deep, moist southerly flow with a decent Gulf fetch
will continue through the weekend as heights begin to fall aloft. PWs
will remain 1 to 2 standard deviations above normal through early
next week...and storms should have good coverage each afternoon over
the weekend and be relatively efficient rain-producers considering
the moisture profiles and deep warm cloud layers. Though the showers
and thunderstorms will be convective...there could be an isolated
flash flood concern by the end of the week if showers and storms can
train over the same areas over multiple days. Pops will remain above
climo both Saturday and Sunday.

By Monday, a more substantial shortwave will be rounding the
longwave trough deepening over the east coast...and a more defined
front may be able to push through the area Monday night and Tuesday.
The falling heights and resulting QG forcing for ascent over much of
the area should lead to good coverage of showers and thunderstorms
Monday afternoon and evening...and pops were increased even more
above climo, though they were capped in the likely range. Whether or
not this frontal passage is clean remains to be seen, as there are
some model disagreements over the depth of the east coast trough and
just how progressive the pattern will be. Temperatures will be
remain about 5 degrees above average through Monday before dropping
to near climo on Tuesday as the upper level trough sits over the
eastern half of the CONUS.

&&

.AVIATION /22Z TUESDAY THROUGH SUNDAY/...
At KCLT this aftn: Chances for convection this aftn appear no
greater than previously anticipated. Consensus of guidance is for
a cluster of activity to form along outflow boundary over the NC
Foothills and NW Piedmont, which will peak in intensity before
it reaches the field. Nonetheless the outflow may bring brisk NW
gusts and some new TS will continue to fire along the boundary
until early evening.

Otherwise: TEMPO TSRA at all terminals except KAND this aftn;
KAND is a bit more removed from the high terrain where the most
widespread convective initiation will occur. Any TSRA will be
capable of gusts above 20KT and brief vsby restrictions. Though sfc
dewpoint depressions will be small tonight, and crossover temps
fairly high, models mostly exhibit dry boundary layers above the
sfc. Given unfavorable profiles and patchy midlevel cloudiness I
only have the confidence to fcst fog at KAVL tonight, given its
valley location. Patchy fog will develop wherever heavy rain falls
from this aftn's storms but it is too early to tell which (if any)
terminals will experience a direct hit. Winds will mainly be SW,
but lee troughing should begin to back those to SW in the Piedmont
(incl KCLT) by midday.

Outlook: Improving boundary layer moisture combined with a weakening
upper ridge will lead to increasing chances for SHRA/TSRA each
day this week. Morning visibility restriction chances will also
increase, mainly in the mountain valleys, but also is possible
outside of the mtns where any precipitation has recently occurred.
