Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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
Topeka, KS (KTOP), launched 00:00Z, 5.8 hours before the alert went out and 102 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.

Area Forecast Discussion National Weather Service Wichita KS 1227 AM CDT Mon Jun 1 2026 .KEY MESSAGES... - Isolated severe storms possible this afternoon and evening, mainly along/east of I-135 - Additional thunderstorms are possible each day next week - Seasonal temperatures over the next week with highs in the 80s to near 90 && .DISCUSSION... Issued at 233 PM CDT Sun May 31 2026 Currently, an elongated, weak mid/upper level trough extends across the Northern Rockies into the Northern High Plains with ridging building in across the southern tier of the CONUS. At the surface, a weak trough is situated across western Kansas. Visible satellite indicates numerous lingering outflow boundaries draped across the central and eastern portions of the state from overnight convection. The moist airmass remains in place, primarily across eastern Kansas where PWATs between 1-1.5" have been observed this morning. As we progress into this afternoon, a sharpening dryline is expected across south-central Kansas into north-central Oklahoma that could initiate afternoon and evening convection once again. Confidence remains low as the ridge to the south begins to build in over the region, leading to increasing heights and weakening overall ascent over the region. Decent instability and sufficient shear would support isolated storms should they manage to develop. Current guidance indicates development along and east of I-135 with activity pushing east through the night. For Monday, a Slight Risk for severe storms returns for central Kansas. A low pressure will develop over the Central High Plains leading to easterly/southeasterly flow. This will support increased moisture and upslope flow across eastern CO/western Kansas. Storm development is anticipated during the afternoon hours across the High Plains. Storms will eventually congeal into a multicellular MCS that will march east-southeastward towards central Kansas during the late evening and overnight hours. Large hail and strong winds will be the main threats across central Kansas for late Monday night/early Tuesday morning. Then through the end of the week, a mid/upper level ridge will continue to build in over the region with the forecast area remaining just north of the ridge axis. This will lead seasonably warm temperatures (middle 80s to lower 90s), and an overall less supportive environment for more potent convection due to synoptic scale subsidence. However, due to the positioning of the upper-level flow, and given the buoyant lower-level airmass, some diurnally driven showers and storms look to develop each afternoon/evening. The potential for widespread severe weather remains low at this time. Confidence remains low on exact location and intensity of any convection for Tuesday through Saturday. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1223 AM CDT Mon Jun 1 2026 Scattered thunderstorms continue across east-central KS and near CNU. -TSRA will likely remain in the CNU area through 09Z or so. Patchy fog is expected to develop across north-central KS with VSBY around 2SM or lower expected. VSBY should improve by mid- morning. Otherwise, easterly winds will become established with additional thunderstorm chances near the end of the period. Confidence in timing and coverage are too low for introduction at this time. && .ICT WATCHES/WARNINGS/ADVISORIES... None. && DISCUSSION...AMD AVIATION...BRF
