What forecasters said that day

The local office's own words before this severe thunderstorm warning 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 severe thunderstorm warning went out at May 27, 12:21 PM CDT, 1 hour 6 minutes earlier.

Area forecast discussion, May 27, 12:21 PM CDT, 1 hour 6 minutes before

Area Forecast Discussion
National Weather Service Wichita KS
1221 PM CDT Sat May 27 2017

.SHORT TERM...(Today through Monday Night)
Issued at 350 AM CDT Sat May 27 2017

Forecast Headline: Severe Thunderstorms With A Trifecta Of
Threats Likely Late This Afternoon & This Evening. (Especially
Across Southeast KS Where Risk Has Been Raised From "Enhanced" To
"Moderate".)

This Morning:
Severe thunderstorms capable of both 1-2 inch diameter hail and
50-60 mph winds continue to surge east 40-45 mph from Northwest
into Central KS. The leading edge has entered Russell & Barton
Counties with the strongest cell approaching Barton County. Per IR
imagery the thunderstorm tops have "kept their cool" with temps
around -60C. With thunderstorms moving into an increasing moist
environment the southern edge of the convection may spread slowly
SE perhaps as far south as Northern Reno & Harvey Counties. The
outflow boundary that the convection is unleashing toward South-
Central KS should stabilize the airmass. SPC 3-hourly MLCAPES
depict such stabilization already in progress with fairly
expansive area of MLCAPES decreasing by 200 J/KG. As such these
thunderstorms should weaken as they venture further into Central
KS.

This Afternoon & Tonight:
No doubt the greatest concern is severe thunderstorm potential.
Short-range models have been consistent in lifting a warm front N
as a broad, positively-tilted upper-deck trough extending from
Central Canada to CA/NV moves east toward, then across the Great
Plains today & tonight. As the trough approaches the warm front
would continue to lift N while cold front surges E/SE toward, then
across, South-Central KS this afternoon. The airmass ahead of the
cold front will be EXTREMELY unstable with SBCAPES soaring into
the 5,000-6,000 J/KG range across the southeast fourth of KS. The
approaching front would no doubt markedly increase shear which
would support supercells with a trifecta of severe threats, among
them very large hail, perhaps tennis ball-sized, and tornadoes. In
fact, the Significant Tornado Parameter is projected to reach 2-3
across Southeast KS with the greater indices situated across far
Southeast KS late this afternoon. With the SE-surging cold front
exiting Southeast KS later this evening, the severe threat would
quickly diminish.

Sunday-Monday Night:
All will be quiet as lower-deck high pressure spreads SE into the
Great Plains.

.LONG TERM...(Tuesday through Friday)
Issued at 350 AM CDT Sat May 27 2017

With several, but fairly weak, mid-level shortwaves scooting SE
across the KS Neighborhood thunderstorms remain in the forecast
for most periods.

&&

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1216 PM CDT Sat May 27 2017

Thunderstorms will be likely for most aviation sites today as a
couple of boundaries play havoc with the weather. A cold front
will drop SE out of NC KS during the day causing enough
convergence to produce storms. These should be more elevated than
those to the south where more surface based storms are possible.
The best instability will reside east of the Flint hills and that
is where the strongest storms will be. CIGS will fluctuate quite a
bit with the mulitude of boundaries and storms. VSBYS should be
good for the most part except when storms are occurring at the
site.
