What was reported inside it

Time	Report	Where	Remark
May 30, 11:59 PM CDT	RAIN 2.82	10 Wsw Tipton, KS	Personal weather station total rainfall for calendar day 5/30. Rain still ongoing.

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 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

Dodge City, (KDDC), launched 00:00Z, 4.8 hours before the alert went out and 197 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.

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Hastings, NE wrote its last area forecast discussion before this flash flood warning went out at May 30, 6:22 PM CDT, 5 hours 26 minutes earlier. Its key messages:

Thunderstorms becoming likely across much of the area this evening, with some severe weather expected. Hail to around 2 inches, wind gusts to 70 mph and an isolated tornado (main potential across north central Kansas) all possible.
Additional periodic chances for showers and thunderstorms across the local area through the end of next week, mainly favoring the evening through late night hours.
Seasonably warm temperatures will continue through the period, with highs most days in the 80s and lows near 60 (averaging about 3-5 degrees above normal).

.DISCUSSION...
Issued at 242 PM CDT Sat May 30 2026

Looks like it will be fairly active across the local area this
evening as CU is just starting to get agitated along the
dryline across southwestern Kansas. Despite fairly marginal
shear, this CU will be moving into an area of increased (and
very strong) instability which will help fuel explosive growth
as they track northward towards the local area. This will most
likely favor some large hail and strong wind gust potential as
the storms expand and merge, but if a few storms are able to
remain discrete, an isolated tornado (as advertised by SPC) will
also be possible across our local area.

This activity across southwestern Kansas this afternoon is only
one area of concern, and a separate area of convection is
anticipated to develop across the high plains to our west in
response to an upper level low rotating across northern
Colorado. Eventually, these two clusters of storms may merge
across the local area by mid to late evening as it lifts
northeast of the area overnight. As these lines of storms merge,
the main threat should transition to strong winds late tonight,
with some possible sub-severe redevelopment hinted at in its
wake during the pre-dawn hours Sunday.

Thereafter...the main upper level low will then lift north
toward Montana by Sunday afternoon, with a weak west
southwesterly flow steering addition weak disturbances across
the local area as we go through the upcoming work week. While
Sunday afternoon/evening looks fairly quiet, this will result in
periodic, mainly evening/night-time chances for thunderstorms
across the local area, along with seasonably warm temperatures
through the end of the extended periods. Overall, the best shot
for some severe weather appears to be with the late afternoon
and evening convection today, but cannot rule out more isolated
chances for strong or severe storms later in the period.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
Issued at 517 PM CDT Sat May 30 2026

For KGRI/KEAR Airports:

Thunderstorms are rapidly approaching the terminals from the
south. Expect these storms to be in the VCTY of both sites over
the next hour or two, with a period of 1-3 hours of reduced
VSBYS and near IFR CIGS as the initial push crosses the
terminals. Could see some redevelopment overnight behind the
initial line and kept a prob30 group from 31/08-31/10 to cover
this. Clearing skies and steady southerly breezes near 12 KTS
are expected to return by the afternoon hours Sunday.
