Local storm reports filed while the alert was in force, from inside its polygon or its counties.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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.

.DISCUSSION...
Issued at 253 PM CDT Mon May 18 2026
Mature trailing stratiform MCS worked through the area overnight
leading to a widespread 1-2 inches of rain across the region. Saw
MCS backbuild across central Missouri through the late morning,
keeping temperatures quite cool through mid-day. Have seen signs of
gravity waves emanating from the tail end of the the MCS, spreading
to the north-northwest.
Have started to see some partial-rapid clearing across eastern KS
into western Missouri leading to nice warming- roughly west of I-35.
Pseudo warm front/outflow boundary is poised just south of the
forecast area across central Missouri. This boundary may try to lift
north through the late afternoon hours. If that occurs, could see
an isolated storms develop south of a line from Butler through
Clinton leading to large hail/gusty winds. Expect surface
temperatures to continue to warm through the afternoon hours into
the upper 70s to 80s, leading to rapidly increasing instability. By
late this afternoon, expect moderate to extreme instability with SB
CAPE values of 4000-5000 J/kg roughly along and west of the I-35
corridor.
Surface low pressure centered near Salina KS is expected to lift
northeast this afternoon to southwest Iowa into the evening.
Discreet supercells have already begun developing across central
into northern KS, building east in time in what is a very volatile
environment. 0-6 km shear is in the 40-50 knot range across eastern
KS should easily support supercells, with the potential for very
large hail and tornadoes. Expect supercells to remain discreet
building into Northwest Missouri in the early evening hours, capable
of producing very large hail, damaging winds and the potential for
strong tornadoes. As the severe weather event evolves, expect the
supercells to evolve into a squalline and build southeast in time.
Expect severe threat to transition towards damaging winds, but could
still see QLCS tornadoes with embedded supercells along the line.
Training storms, along with precipitable water values of nearly two
inches and deep warm cloud depths will lead to efficient rainfall.
CAMs have been fairly consistent with another 1.5-3+" of rainfall
across the region tonight, with pockets of 5+". HREF and REFs
probabilities for 2"/hr rainfall rates are approaching 50%. Flash
flood guidance across the area is low with the recent rains,
generally running from 1-2.5"/6 hour period. Collaborated with WPC
and surrounding offices to raise excessive rainfall outlook to
moderate across most of the area. Cams suggest storms may linger
Tuesday morning as the surface boundary moves slowly through the
area. Have extended the flood watch through 18Z south of the
Missouri River.
Much cooler conditions are expected midweek behind the front with
high in the 60s and lows in the 40s. A developing trough late week
across the Northern Plains could bring additional instability
showers and storms to the region as early as Thursday.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 650 PM CDT Mon May 18 2026
SE winds will continue with gusts up to 30 mph through the early
evening hours, then winds shift SW between 01z-03z and remaining
gusty. A line of severe thunderstorms will impact STJ between
01z-03z tonight, moving through the KC metro terminals likely
between 02z-05z tonight. Severe wind gusts will be possible
along the leading edge of the severe thunderstorm line, with
periods of moderate to heavy rain reducing visibility
significantly. Stratiform rain with isolated lightning strikes
will linger behind the main convective line into early tomorrow
morning. There is a potential (30-50%) terminals will see
reduced visibility around 4SM and BR between 10z-14z.

Once this occurs, damaging wind gusts should become the primary hazard, but a few brief tornadoes may be possible. - Moderate to heavy rain will be possible again with the storms tonight. A flood watch is in effect through almost the entire CWA through 7 AM Tuesday. - Cooler temperatures arrive for Tuesday through Thursday before heating up once more by this weekend.
