Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
1138 AM EST Thu Nov 12 2020

The National Weather Service in Greenville-Spartanburg has extended 
the

* Flash Flood Warning for...
  Cabarrus County in the piedmont of North Carolina...

* Until 300 PM EST.

* At 1138 AM EST, Doppler radar was showing that the threat for 
  additional heavy rain was coming to an end.  However, after this 
  morning's widespread 3 to 4 inch rainfall, with locally higher 
  amounts, flooding continued across much of the county.  This 
  includes, but is not limited to, greater Concord and the I-85 
  corridor, and just about all the tributaries which feed the Rocky 
  River.  It is likely that flooding along the Rocky River proper 
  will linger well into tonight.



  HAZARD...Life threatening flash flooding.

  SOURCE...Doppler radar and automated gauges.

  IMPACT...Life threatening flash flooding of creeks and streams,
           urban areas, highways, streets and underpasses.

* Some locations that will experience flash flooding include...
  Kannapolis, Downtown Concord, West Concord, Davidson, Harrisburg, 
  Enochville, Mt Pleasant, Charlotte Motor Speedway and Coddle Creek 
  Reservoir.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Warning means that flooding is imminent or occurring. 
If you are in the warned area move to higher ground immediately. 
Residents living along streams and creeks should take immediate 
precautions to protect life and property.

Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
252 PM EST Thu Nov 12 2020

The National Weather Service in Greenville-Spartanburg has extended 
the

* Flash Flood Warning for...
  Cabarrus County in the piedmont of North Carolina...

* Until 600 PM EST.

* At 252 PM EST, Heavy rain has ended across Cabarrus County and no 
  additional rainfall is expected for the duration of the flood 
  event.  However, after this morning's widespread 3 to 5 inch 
  rainfall, with locally higher amounts, several streams are 
  continuing to rise rapidly and are well above their banks.  
  Therefore, the threat for worsening flash flood conditions, 
  especially along primary streams across Cabarrus County including 
  Coddle Creek, Mallard Creek, Irish Buffalo Creek, Cold Water 
  Creek, Dutch Buffalo Creek, and the Rocky River will continue into 
  the early evening hours.  To highlight the potential for 
  significant flooding along these streams, especially the lower 
  portions of Coddle Creek and the Rocky River near Georgeville, NC 
  200, and Mt Pleasant Rd, the Flash Flood Warning has been extended 
  until 6pm.

* It is critically important that residents near streams continue to 
  seek higher ground and avoid the flood plain until the streams 
  crest and begin to recede.  Drivers are urged to stay away from 
  flooded roadways and obey all barricades, which are in place for 
  your protection.  Many roads may have been compromised by flash 
  flooding and may not be safe, even if there is no water over them.

  HAZARD...Life-threatening flash flooding due to previous heavy
           rainfall.

  SOURCE...Automated streamgauges

  IMPACT...Life-threatening flash flooding of creeks and streams,
           urban areas, highways, streets, bridges and
           underpasses.  A few structures may be impacted by
           rapidly rising floodwaters.

* Some locations that will continue to experience flash flooding 
  include... Kannapolis, Downtown Concord, West Concord, Davidson, 
  Harrisburg, Enochville, Mt Pleasant, Charlotte Motor Speedway and 
  Coddle Creek Reservoir.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Warning means that flooding is imminent or occurring. 
If you are in the warned area move to higher ground immediately. 
Residents living along streams and creeks should take immediate 
precautions to protect life and property.

Excessive runoff from heavy rainfall will cause flooding of small 
creeks and streams, urban areas, highways, streets and underpasses 
as well as other drainage areas and low lying spots.

Stay away or be swept away. River banks and culverts can become 
unstable and unsafe.

...FLASH FLOOD WARNING WILL EXPIRE AT 6 PM EST THIS EVENING FOR 
CABARRUS COUNTY...

The Flash Flood Warning for Cabarrus County will expire as the 
flash flood threat has ended.  However, larger streams are still 
cresting and residual flooding concerns are widespread, therefore a 
Flood Warning has been issued to replace the Flash Flood Warning.

A Flood Warning is in effect to highlight residual Minor flooding 
following earlier flash flooding.  Numerous roadways may still be  
flooded and closed.  A few structures may still be threatened by
floodwaters.  Extensive and significant flooding of low-lying areas 
adjacent to streams including farmland, parks, greenways, boat 
access areas, and other locations is ongoing.

Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
701 AM EST Thu Nov 12 2020

.SYNOPSIS...
A slow moving cold front is expected to move across the region
today providing a focus for additional showers and storms. The
front should move off to the east tonight, followed by dry air
moving in from the west on Friday. High pressure moving past to
the north should control our weather for most of the weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 650 AM Thursday: The cold front is about half way thru
the forecast area attm, slowly pushing east. So all the heavy
rain has set up across the eastern zones. Rain rates/updrafts
have trended upward along the eastern edge of the precip band,
with highest rates from Greenwood County thru the Charlotte metro
area to the Triad. Flash flooding remains a real concern in those
areas. To the west, with the rain pulling out, have removed some
of the western zones from the FFA. The French Broad Valley and the
Northern Mountains have been left in the FFA due to ongoing runoff,
but will probably be able to be canceled with the next update.

From the 330 AM update...A leading shortwave trough exiting a broad
longwave 500 mb trough across the central CONUS will produce strong
upper divergence atop the forecast area thru this morning. The
mid and upper level support will be coupled with a slow-moving
cold front, which has already push into the NC mountains and will
continue to advance east thru the day. PWATs are still running at
record levels along and ahead of the front. And forecast soundings
show very deep warm cloud layers and unidirectional flow that
supports training convection. All this to say that the flood
threat is probably at its highest over the next 6-8 hours or so,
especially along and east of the Blue Ridge Escarpment. No changes
were made to the Flood Watch with this update, but some of the
counties in the western and central NC mountains may be able to be
canceled with the next update. As a frontal band of heavy showers
(and possibly some isolated embedded tstms) will set up over the
I-77 corridor right around daybreak. Guidance shows an additional
1-3", with locally higher amounts.

Around noon...the heaviest convection should begin to exit to our
east, with Union County, NC, being the last to clear out. Low-level
flow behind the front will be fairly weak, and forecast soundings
show low clouds stubbornly holding on thru the aftn. The exceptions
will be in the western mountains and the Upper Savannah Valley,
which could see more sunshine before sunset. Temps will be tricky,
as too many breaks in the clouds could allow temps to shoot
up several degrees warmer than the current forecast. For now,
think they will range from the lower 70s northeast to upper 70s
southwest. Dewpts will come down from the lower 70s to mid 60s,
so it will still feel fairly humid.

Tonight...dry air continues to filter in from the west, but
low-level moisture lingers. It could be a good fog night for some
areas, but high pressure building in from the west and T.C. Eta
tracking along the GA/SC coast will keep a pressure gradient
atop the area. So still think it will be more of a low stratus
deck that forms with patchy fog, rather than widespread dense
fog tonight. Temps will start falling like usual around sunset,
but may not get below our record high minimums at any of our
climate sites before midnight. Lows will be mainly in the 50s,
still about 14-18 deg above normal.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
As of 138 AM EST Thursday: Autumn is on track to return to the
western Carolinas and northeast Georgia for the weekend. The
moisture gradient should be across the fcst area at daybreak Friday
and is expected to push east during the day with a modest WNW flow
at 850mb, ushering in the dry air associated with high pressure to
our west. A flat upper ridge will carry that surface high past to
the north through Saturday, giving us a classic autumn day with
temperatures right around normal. The high will migrate off the
Mid-Atlantic coast Saturday night, with some weak moisture return by
daybreak Sunday. Think the guidance is a little premature suggesting
that some upslope light precip might develop around daybreak Sunday
near the Escarpment. Prefer to keep the fcst dry for now.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 321 AM EST Thursday: A broad upper trof moving east across
the Plains will push a cold front in our direction on Sunday, but
forcing and moisture return looks minimal. Guidance was generally
accepted with a chance of showers ramping up over the mtns/foothills
through the afternoon. The front should move quickly through the
region given such a low amplitude upper pattern, so we dry out
again Sunday night as the upper trof axis moves past. After that,
high pressure will build in from the west and dominate through
Tuesday, before a dry reinforcing front moves through followed
by the next surface high building in from the NW for the rest of
the period. Temperatures will be on the order of a category below
normal for most of the period.

&&

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
At KCLT and elsewhere: At time of 12z TAF issuance, a slow-moving
cold front had just passed thru KHKY and was about to cross the
Upstate TAF sites. Conditions have briefly improved in those sites
in the wake of heavy rain showers, but will likely return to IFR or
at least low MVFR for a few hours this morning. The front will pass
thru KCLT around 14z, shifting the winds from S to N. The line of
heavy showers and embedded tstms should start to shift east in the
14-17z time frame. Drying starts to take over after 18z, but not
enough to scour out the low cigs, which look to remain generally
MVFR, except for some scattering out in the Upstate and at KAVL. The
low cigs will likely persist tonight as well, with guidance showing
LIFR possible east of the mountains overnight. There is some hint
in the guidance that winds may become light enough to allow fog
to form, but overall, it looks mostly like a stratus event tonight.

Outlook: Dry high pressure will finally build in Friday, scouring
out the low clouds and any fog that's around Friday morning,
bringing back mostly VFR conditions thru the weekend.
