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.

The nearest sounding before it

Springfield, MO (KSGF), launched 00:00Z, 0.1 hours before the alert went out and 142 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

...AVIATION UPDATE...

.SHORT TERM...(This evening through Monday)
Issued at 238 PM CDT Sun Apr 7 2019

Even though showers and storms have not yet developed, our area
remains in the warm sector ahead of an advancing cold front over
eastern Kansas this afternoon. Dewpoint temperatures were in the
upper 50s to lower 60s, and the latest RAP soundings using the
Near Storm Environment Awareness program show current surface
based CAPE over 2000 j/kg. 0-6km bulk shear is marginal with
values at or below 30 knots. While better low level moisture
remains well to our south, think storm development will be
possible along the front from later this afternoon through
tonight.

Monday still looks warm and dry with highs once again reaching the
70s.

.LONG TERM...(Monday Night through Sunday)
Issued at 238 PM CDT Sun Apr 7 2019

Mainly monitoring trends with the storm system deepening over the
central High Plains on Wednesday and moving across our region
Wednesday night and Thursday. Initial concern will be increasing
southwest winds that will have the potential to gust to over 30
mph, especially Wednesday afternoon and evening. There is pretty
decent consistency on the placement of the surface and upper level
low over southeast Nebraska Thursday morning, but some differences
on precipitation placement. In fact it looks like some areas may
get missed altogether on precip as a well developed dry slot is
progged to move over our area. For now have maintained very low
precip chances as it appears there will be access to gulf
moisture.

Next concern will be the colder temperatures spilling into our
area behind this system on Thursday-Saturday. Both the ECMWF and
GFS have the 540 dm thickness line bisecting our forecast area on
Friday afternoon. Only slight rebounding in thickness shows up by
Saturday morning. Thus confidence remains fairly high in the
temperature trends for later this week.

Later in the weekend an upper level trough moving across the
southern Plains could bring rain to the region during the latter
part of the weekend.

&&

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)

Pilots flying in and out of the southwest Missouri airports can
expect fair weather VFR conditions over the next 24 hours.

A few thunderstorms will develop over the eastern Ozarks, however,
they should remain away from the TAF sites.

Look for light and variable breezes tonight with no low ceilings
or reduction to visibility.

Safe Travels.

&&

.FIRE WEATHER...
Issued at 238 PM CDT Sun Apr 7 2019

On Wednesday afternoon we could see some fire weather concerns as
southwest winds increase to over 30 mph at times while
temperatures rise into the 80s and minimum relative humidities
fall below 40 percent.
