Local storm reports filed while the alert was in force, from inside its polygon or its counties.
Did it verify
Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this flash flood warning; the first came 60 minutes after it went out.
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
Topeka, KS (KTOP), launched 00:00Z, 9.7 hours before the alert went out and 56 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.

.DISCUSSION...
Issued at 230 AM CDT Sun Jun 21 2026
Widespread showers and storms have moved from southeastern NE
and eastern KS into northwestern MO this evening. How this
convection evolves through the morning is the primary concern of
this forecast cycle. A well-estabilished MCS in south central KS
has pivoted from a southeast motion to an eastward propagation
with the development of an MCV on the northern edge. As the LLJ
has ramped up over the last couple of hours, a distinct bowing
segment has formed. The current forecast track would have the
center of this bow moving either just south of the CWA or
through southern Linn (KS) and Bates Counties meaning that
severe weather, particularly severe winds, is possible across
eastern KS and far west-central MO, including the KC Metro.
However, given the timing of this system (well after midnight),
the expectation is for a weakening trend as it advances
eastward, so some uncertainty remains in the true severe weather
potential across the southern portion of the CWA. However,
given that there is the potential, a Severe Thunderstorm Watch
has been issued for the KC Metro and areas south through 6 AM
CDT.
A more concerning trend that has developed over the past few
hours is the potential for training storms along the I-70
corridor leading to flash flooding. Storms across northern KS
and northern MO have been slowly shifting south and have begun
to orient themselves in a west-to-east manner along the I-70
corridor in central KS resulting in prolonged periods of heavy
precipitation (rainfall rates of 1-2 inches per hour). This
looks poised to continue into eastern KS and western MO, which
could result in 2-4 inches of rain in just a couple of hours
across northern MO. Current 3-hr flash flood guidance is ~1.5-2
inches, so this is quite concerning. A Flood Watch remains in
effect through 7 PM CDT for all of western MO and eastern KS.
This complex of showers and storms is expected to continue
through the morning and exit the area to the east by early
afternoon. A remnant outflow boundary/modified warm front will
be draped across central MO. This boundary will be focus for
renewed convection this afternoon (development around 1-2 PM
CDT) before a cold front sweeps through the area with the best
chances coming along and south of I-70. Elevated PWATs (in
excess of 2") will allow for effective rainfall rates and
another chance for flash flooding. Afternoon MLCAPE values of
1000-2000 J/kg paired with deep layer shear on the order of
40-45 kts will also allow for a severe weather threat. The
primary threats are wind and hail, but given the presence of a
boundary in the area, certainly cannot rule out a tornado or
two. North of the boundary, there is a threat for elevated
storms, which creates the potential for hail and perhaps a
marginally severe wind gust. This thinking aligns with the SPC
as the southern portion of the area is in a Slight (Level 2 of
5) Risk and areas north of I-70 are outlined in a Marginal
(Level 1 of 5) Risk.
Moving past Sunday, a lull in active weather looks to be on the
way. High pressure builds into the area on Monday with upper-
level zonal flow. Temperatures will be cooler after the cold
frontal passage Sunday afternoon/evening with highs in the mid-
to-upper 70s. A gradual warming trend is expected through the
first half of the week with temperatures climbing into the low-
to-mid 80s. Precipitation chances remain minimal through the
majority of the week before the next chance (20-40%) moves in on
Friday with a mid-level shortwave, however, a good amount of
uncertainty remain that far out.
&&
.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1227 AM CDT Sun Jun 21 2026
Showers and storms are expected to arrive at the terminals over
the first couple hours of the TAF period. KSTJ will likely have
storms ongoing at 06Z with storms spreading southward over the
next couple of hours. These storms will be accompanied by
lowered visibilities and MVFR CIGs. MVFR conditions should
persist through the morning with low-end probabilities for IFR
CIGs in the late morning. Showers and storms will come to an end
through the morning, however, MVFR CIGs should stick around
into the afternoon before scattering out. MVFR CIGs may return
late this evening, but confidence is not high enough to include
in the TAFs at this time. Winds will begin the period as
easterly before shifting to southerly and southwesterly through
the morning. Gusts of 20-25 kts are possible through the
morning. Winds will flip to northerly this afternoon.
