What happened

The episode as NWS TOP wrote it up.

Supercell thunderstorms developed ahead of a dryline and near a warm front during the afternoon and evening hours of May 18. The storms produced 7 documented tornadoes and eventually evolved into a line of storms that produced damaging winds of 60-80 mph across northeast and east central Kansas. Some areas also received 2-5 inches of rain just two to three hours causing flash flooding in several areas including the city of Manhattan.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Topeka, KS wrote its last area forecast discussion before the first event at May 18, 11:23 AM CST, 1 hour 28 minutes earlier. Its key messages:

Numerous severe storms are expected late this afternoon over north central Kansas, spreading across northeast Kansas this evening and overnight. Threats include very large hail (2-4+ inches in diameter), Damaging wind gusts to 80 mph, flash flooding, and tornadoes (a few strong).
A Flood Watch is in effect for all of northeast and north central Kansas where antecedent heavy rainfall has enhanced the threat for flash flooding this evening.
After cooler and dry conditions Tue. and Wed., storm chances return with the highest being on Thursday. Widespread severe probabilities are low at this time.

.DISCUSSION...
Issued at 232 AM CDT Mon May 18 2026

Active early Monday morning as a decaying line of slow moving
thunderstorms impacts portions of northeast and east central Kansas.
Overall threat has shifted to heavy rainfall as hourly rainfall
rates of 1 to 2 inches have been observed. Totals have currently
ranged from 1 to 5 inches with the highest amounts focused over
north central Kansas. As the low level jet wanes, activity is
anticipated to dissipate by mid morning, leaving the stratus in
place and potentially an outflow boundary in far eastern Kansas to
MO. How quickly the atmosphere recovers in eastern Kansas is
uncertain, potentially generating scattered severe storms by mid
afternoon. Confidence in this scenario is somewhat bolstered by the
last few runs of the HRRR/RAP, forming convection south of I-70 and
east of I-35. Forecast soundings in vicinity of this outflow
boundary exhibit strong low and mid level wind shear and elevated
CAPE up to around 3000 J/KG. If this occurs, damaging wind gusts,
large hail, and a few tornadoes cannot be ruled out earlier in the
afternoon. Overall confidence for the above scenario is low-medium,
owning to timing and location inconsistencies of current convection
and where the boundary settles by midday.

In terms of the main severe weather setup, no major changes were
noted in forecast trends as the moderate severe risk from SPC
remains centered from the Flint Hills region to the Kansas/Nebraska
border. Negatively tilted upper trough axis across the Four Corners
Region is anticipated to eject into the western high plains between
21Z-00Z. At this time, dryline/cold front is oriented southwest to
northeast over north central Kansas as rich low level moisture
raises dewpoints into the low 70s pooling just ahead of the stalled
boundary. In addition clouds are anticipated to scatter out by late
afternoon, resulting in SFC CAPE exceeding 5000 J/KG amid minimal
inhibition. Strong convergence along the front is sufficient for
discreet convection to form in the 3-5 PM timeframe over north
central Kansas. Initial severe storms will be most intense in terms
of very large hail (2-4+ inches diameter) and strong tornadoes,
especially as the low level jet strengthens in the early evening.
The strong tornado threat persists into the early evening with any
discrete supercells.

Bulk shear vectors parallel to the front suggest discrete cells
transition to a line of storms around 7 PM. Main hazards with the
squall line are damaging wind gusts to 80 mph , brief tornadoes
along the leading edge, and large hail as they quickly translate
east southeast through eastern Kansas. Forward propagating corfidi
vectors are weak (20 kts) while PWAT values increase above 1.5
inches and low/mid level moisture saturates the column. Given the
several inches of rainfall that occurred the last evening, decided
to expand the Flood Watch to cover the entire forecast area through
Tuesday morning. Estimated rainfall totals tonight range from 2 to 5
inches, increasing the likelihood for localized flash flooding.
Activity exits into Missouri between 3 and 6 AM Tuesday.

Much cooler airmass settles in behind the front Tuesday and
Wednesday afternoons as highs only peak in the middle to upper 60s.
Showers and isolated storm chances return by Thursday as broad upper
troughing amplifies to the north and west. However, given the
influence from sfc ridge to the northeast and lack of good return
moisture, the overall severe threat is low. Better dynamics return
by Friday evening, signaling the possibility for strong storms in
the Kansas region.

Confidence is increasing in thunderstorm potential in the 23Z-04Z
window and went ahead with TEMPO inclusion. MVFR cloud should
diminish soon but be more consistent after FROPA around 06Z with some
chance for improvement late in the forecast.

tornadoes are the main hazards.

Localized flooding is also a concern, especially if storms
persist over areas that received heavy rain Sunday night. A Flood
Watch remains in effect through 7 AM Tuesday morning.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

The probability for widespread hazardous weather is low.

.SPOTTER INFORMATION STATEMENT...

What these are

Hail: Hail three-quarters of an inch or larger, or smaller hail that caused damage, filed with the largest stone measured.
Tornado: A violently rotating column of air in contact with the ground and extending from a thunderstorm, filed with its path, width and Fujita or Enhanced Fujita rating from the damage survey.
Thunderstorm Wind: Winds from a thunderstorm of 50 knots (58 mph) or more, or lower winds that caused damage or casualties. Measured gusts are marked MG, estimated EG.
Flash Flood: Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.
