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
432 PM CDT Sun Apr 27 2014

.DISCUSSION...
Issued at 431 PM CDT SUN APR 27 2014

Main focus for this afternoons forecast package is squarely on any
continuing potential for severe weather through the late afternoon
and evening hours.

The leading line of convective activity has taken much of the day to
move east across our section of Kansas and Missouri owing to the
vertically stacked nature of the upper level through that is
swinging into the Plains States. This convection brought reports of
large hail and damaging winds, but has also brought cooler --upper
50s into the 60s-- more stable air. Storms that redeveloped across
extreme northeast Oklahoma/southeast Kansas are moving rapidly --50
mph-- to the north northeast. This redeveloping line of storms are
quickly moving into a airmass that is still well worked over from
early activity --temperatures in the low 60s over dew points in the
50s-- with a decent easterly component to the surface wind. These
storms have struggled to reach severe limits as a result. However,
still watching areas of northeast Oklahoma and southeast Kansas as
the agitated CU field --seen arching back to the northwest across
Manhattan KS-- is growing pointing at the next region of
development. Models continue to advertise this activity growing over
the next couple of hours along the dry line, but the dry slot aloft
my inhibit growth despite the boundary destabilizing. Ultimately,
current expectations are that the storms will continue to percolate
along the dryline, shifting north northeast into far western
Missouri through the late afternoon and early evening hours.
However, the focus for robust severe storms looks to slide east into
southern Missouri, while areas farther north through Kansas City
will likely have to deal with elevated convection and the attendant
torrential rain and large hail threat. Convection will start to fade
as the sunsets this evening across the northern half of Missouri,
with the activity spreading north northeast and fading going into
the evening hours.

Monday on through the work week...haven't changed much. The trough
moving into the Plains today is still expected to take its time
moving across the nation as it detaches form the main progressive
flow. Result, cool temperatures with showers possible on and off
through the week. Expect highs to likely be limited to the 50s
Tuesday through Thursday with overnight lows around 40.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday Afternoon)
Issued at 1228 PM CDT SUN APR 27 2014

Current thunderstorm activity along the Kansas-Missouri border will
persist into the early afternoon hours before shifting farther east.
Conditions with the storms in the area will range from MVFR rain to
LIFR thunderstorms. Redevelopment of storms looks possible to the
west through the mid afternoon hours, so have kept VCTS through 00Z, but
after that it look like the threat for thunderstorms will move east.
Otherwise, breezy winds will persist into the evening hours before
decoupling late tonight.
