...FLASH FLOOD WATCH IS CANCELLED...

The Flash Flood Watch for portions of Central Kansas, South
Central Kansas, and Southeast Kansas has been cancelled. The
heavy rain from earlier this evening has moved out of the area and
the threat of flash flooding has decreased for the remainder of 
the overnight hours. Please continue to heed road closures until 
the water has receded and monitor creek and river levels. Flooded
roads can be harder to see at night, so caution is advised for 
those planning to drive overnight.

...FLASH FLOOD WATCH NOW IN EFFECT UNTIL 4 AM CDT THURSDAY...

The Flash Flood Watch is now in effect for

* a portion of South Central Kansas, including the following 
  areas, Cowley, Harper, and Sumner Counties. 

* Until 4 AM CDT Thursday.

* Intense rainfall rates are likely through late tonight due to a
  slow-moving band of thunderstorms in the area. This band of
  thunderstorms has a history of producing 1 to 2 inches of rain
  in a short amount of time and has led to several reports of
  flooded roads, creeks, and rivers. Areas not currently
  experiencing flooding may soon.

* PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that will 
cause flash flooding. Flash flooding is a very dangerous 
situation. Remember to turn around, don't drown. Never drive 
through flooded areas, especially at night! You should monitor 
later forecasts and be prepared to take immediate action should 
flash flood warnings be issued.

What forecasters said that day

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

NWS Wichita, KS wrote its last area forecast discussion before this flash flood watch went out at Sep 2, 3:35 AM CDT, 32 minutes earlier.

Area forecast discussion, Sep 2, 3:35 AM CDT, 32 minutes before
Area Forecast Discussion
National Weather Service Wichita KS
335 AM CDT Sun Sep 2 2018

.SHORT TERM...(Today through Tonight)
Issued at 327 AM CDT Sun Sep 2 2018

Active weather pattern setting up the next several days, with
periodic rounds of showers and thunderstorms with heavy rain
likely. Will issue a flash flood watch for this afternoon through
tonight for Barton, Ellsworth, Saline, Russell and Lincoln
counties.

Model consensus supports a solid signal for slow-moving and
training thunderstorms producing a swath of intense rainfall rates
anytime from mid-late afternoon through the evening. While the
exact location of this band of storms is uncertain, highest
confidence is somewhere north of a line extending from Great Bend
to Salina. The culprits are strengthening moisture transport into
a quasi- stationary boundary, amidst a deeply moist/unstable
airmass. An estimated 2-4 inches of rain fell yesterday evening
across the western half of Russell county, where the ground is no
doubt already saturated. Additionally, even though mid-level lapse
rates aren't quite as steep as yesterday, ample deep layer shear
and instability should support a handful of afternoon-evening
strong to severe storms, especially north of that Great Bend to
Salina line.

Kleinsasser

.LONG TERM...(Monday through Saturday)
Issued at 327 AM CDT Sun Sep 2 2018

Model consensus supports this active weather pattern persisting
across the Kansas region through at least mid to late week, as a
slow-moving deep longwave trough spins over the central and
southern Rockies, ejecting periodic shortwaves northeast over the
region. Consequently, unseasonably rich and deep tropical moisture
will continue to spread north, enhanced by disturbances moving
north/northwest out of the Gulf of Mexico.

For Monday and Tuesday, with a lack of appreciable focus,
scattered shower/thunderstorm activity should be hit-or-miss
across the region, with high precipitable water values and weak to
modest instability supporting intense rainfall rates with any
activity that forms. For Wednesday and Thursday, a cold front
sinking slowly south across the Kansas region will provide more
of a focus for numerous/widespread showers and thunderstorms
areawide, with a continued threat for intense rainfall rates.
Model solutions diverge beyond Thursday, with the ECMWF much
slower than the GFS exiting the cold front east, which would
support continued unsettled weather possibly through next weekend.

Later shifts may eventually need to contemplate additional
flood/flash flood watches across all or portions of the area
anytime Monday and beyond, especially once confidence increases on
timing and/or location of expected showers/storms.

.AVIATION...(For the 06Z TAFS through 06Z Sunday night)
Issued at 1159 PM CDT Sat Sep 1 2018

Convective trends are still the main issue. VFR conditions
expected outside of storms. Storms will continue to flirt with
KRSL and KGBD for the next few hours. Enhanced lift and veering
flow aloft will should lead to a few showers/storms a bit later at
KHUT-KICT in the 09-15 UTC. Isolated storms could develop in the
afternoon, but are more likely at during the evening, especially
at KRSL. -Howerton
