The radar
The Des Moines radar (KDMX), 158 km from the middle of the area, began a volume at 10:42 UTC, the scan nearest the moment this went out.

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.

AREA FORECAST DISCUSSION
National Weather Service Kansas City/Pleasant Hill MO
410 AM CDT Mon May 27 2019
.Mesoscale Discussion...
Issued at 402 AM CDT MON MAY 27 2019
IR satellite imagery shows warming cloud tops through 4 am with
the line of storms approaching eastern Kansas, and most recent
ground reports reveal 40 to 45 mph wind gusts as storms continue
to weaken. These storms will still be capable of producing 40 to
50 mph wind gusts across the Kansas City metro and surrounding
areas through 6 am, and heavy rainfall may lead to ponding of
water on roadways during the morning commute. The overall severe
threat will, however, continue to diminish as the morning
progresses.
&&
.Discussion...
Issued at 318 AM CDT MON MAY 27 2019
A well-organized line of storms continues to push east across
central Kansas and should arrive into eastern Kansas and western
Missouri between 4 to 5 am. Storms continue to move into an area of
moderate instability with a strong rear inflow jet filtering in
behind the line at 700 hPa. The line should have ample momentum to
maintain a threat for strong to damaging wind gusts up to 70 mph
through the early morning. Given the saturated soils in place across
the affected areas, it is possible that trees may become uprooted as
the line progresses through the area. As storms continue to push
east, a gust front should form as the line enters a more stable
environment and slows with time. While it is possible that the
severe threat may extend into central Missouri this morning, storms
should weaken overall by the mid-morning time frame.
For the remainder of the day, additional thunderstorms will form
across northern Missouri this afternoon and into the evening hours,
capable of producing large hail and damaging winds, with an isolated
tornado risk. A surface low will advance into the Great Lakes region
with an attendant cold front stretched across southern Iowa this
afternoon. Meanwhile, continued warm advection ahead of a deepening
surface low over eastern Colorado will push against the northern
frontal boundary as a warm front, eventually stalling the boundary
across southern Iowa. This will occur within a moderately
destabilized environment and deep layer shear values over 40 knots.
Will need to see how morning convection modifies the environment,
though surface convergence should be sufficient for storms to
develop by the early afternoon. Additional flash flooding is
possible across northern Missouri during this time, as rainfall will
remain very efficient through the event.
Round three of active weather will arrive Tuesday afternoon and
evening as the advertised deep upper low across the west coast lifts
northeast and approaches the Central Plains in the afternoon
Tuesday. Initial storms will form across central to eastern Kansas
within an environment of 2500 to 3000 J/kg of MLCAPE and bulk shear
of 40 to 50 knots. Discrete storms should form a line upon entering
eastern Kansas with strong to damaging winds and large hail being
the primary threats. The potential for tornadoes will increase by
the early evening as the low-level jet strengthens from central
Oklahoma into south central Iowa. Additional flash flooding is also
possible as the tropical air mass will remain well in place,
maintaining existing PWAT values of 1.5 to 1.8 inches.
Additional thunderstorm development is possible Wednesday afternoon
as models have recently depicted a slower eastward progression of
the closed low, likely stemming from the downstream blocking pattern
over the southeastern CONUS. Favorable ingredients for severe
potential will have shifted southeast, though storms that do form
will likely once again yield heavy rainfall across central to
eastern Missouri. A multi-day dry period is expected beginning
Thursday morning as the pattern aloft becomes nearly zonal. However,
embedded impulses will bring a return of the wet pattern by the
early weekend.

.Aviation...(For the 06Z TAFS through 06Z Monday Night)
Issued at 1135 PM CDT SUN MAY 26 2019
Line of showers and embedded thunderstorms is still on track to
arrive in western Missouri 09-14Z. Expect MVFR conditions in and
near showers and thunderstorms, otherwise expect VFR conditions
throughout the TAF period for all sites. Majority of thunderstorm
activity will occur over northern Missouri and impact KSTJ, while
further south, isolated thunderstorms are anticipated for the
Kansas City Metro TAFs. South winds near 10kts will continue over
the next few hours and then increase with gusts near 25kts for
the remainder of the forecast. NOTICE: Due to weather observations
unavailable at KIXD, the TAF will be NIL or also unavailable.
