Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

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 Nov 30, 6:12 PM CST, 4 hours 21 minutes earlier.

Area forecast discussion, Nov 30, 6:12 PM CST, 4 hours 21 minutes before

Area Forecast Discussion
National Weather Service Wichita KS
612 PM CST Fri Nov 30 2018

.SHORT TERM...(This evening through Monday night)
Issued at 300 PM CST Fri Nov 30 2018

Vigorous shortwave moving out of the southern Rockies will rapidly
move into the plains this evening and overnight.  As it lifts north
it will be become vertically stacked and take on a more negative
tilt as it moves into ern KS.  Large scale ascent and diffluent flow
will lead to widespread showers and some thunderstorms, increasing
across most of the forecast area late this afternoon into this
evening. System is coming out a little slower and deeper than
previously thought, which will allow better low level moisture to
increase into areas east of the KS Turnpike by this evening. Latest
hi-rez models solutions suggests bulk shear of 65-70kt and MUCAPE
values increasing to 1500-1700 J/KG by this evening. Of a bigger
concern is increasing surface based instability (1200-1500 J/KG) and
0-1 km shear (35-40 kts) and directional shear, which suggests a low
topped supercell threat for areas over SE KS this evening. This
increasing low level instability, combined with the above mentioned
bulk shear, suggests an increasing chance of severe storms for SE KS
(see latest Day 1 SPC outlook), if the storms can become rooted in
the boundary layer. Its still somewhat conditional or whether this
will occur, or if the storms will stay slightly elevated. With that
in mind, quarter size hail/60 mph winds, look to be the main
concern, but a brief tornado cannot be ruled out, given 0-1km shear
values. Could see a few strong storms to the west of this main
severe threat area, extend back to the KS turnpike, as elevated
instability increases to 1500 j/kg late this evening.

The mid/upper shortwave deepens as it makes slow progress north and
east into the Missouri Valley on Sat with some lingering light
precipitation likely across much of northern KS. Light rain may mix
with snow at times as colder air gets wrapped into the system, but
any accumulations are expected to remain light at this time. Gusty
northwest winds are also anticipated with 20-30 knot gusts possible
across central KS.

Below normal temperatures will prevail again on Sunday as a mean
mid/upper trough remains in place across the CONUS. Maintained some
low pops along the I-70 corridor where a light wintry mix will
remain possible.

Ketcham

.LONG TERM...(Tuesday through Friday)
Issued at 300 PM CST Fri Nov 30 2018

A broad mid/upper trough will remain over the central plains for the
start of the work week. This will lead to an extended period of
below normal (ie...cold) temperatures.  The first shot of cold air
will arrive across the area early in the week with little if any
moderation before the next blast arrives early on Thu. The middle of
the week looks dry, but a southern stream system moves north over
the top of the shallow cold air for late Thu into Fri. At this time
it looks like another shot of wintry precip by Fri.

Ketcham

&&

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 605 PM CST Fri Nov 30 2018

Poor aviation conditions to continue through the night due to low
clouds, fog, and TSRA.

A dynamic storm system continues to encroach on the area from the
west this evening. At the surface, a warm front stretches across
the state of Oklahoma. North of that front, an easterly/upslope
low level flow has lead to widespread low clouds and fog with
widespread IFR/LIFR condition at this time. Later tonight,
SHRA/TSRA will move through the area, adding to the impacts to
aviation. The strongest storms may contain large hail, with a
low-end threat of wind gusts of 50+ kt. TSRA should clear the area
after Midnight, with gusty NW winds developing in the wake of the
system. Some -SN may impact KRSL/KSLN/KGBD on the backside of the
system, but confidence in how far south winter precip will reach
is less certain.
