The radar

The Topeka radar (KTWX), 78 km from the middle of the area, began a volume at 03:06 UTC, the scan nearest the moment this went out.

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.

What forecasters said that day

The local office's own words before this tornado warning went out, 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 this tornado warning went out at Jun 10, 6:25 PM CDT, 3 hours 42 minutes earlier. Its key messages:

  • Storms are expected to develop across northeast into central KS this afternoon and early evening, some of which could be severe. Large hail, damaging wind, tornadoes, and locally heavy rainfall are all possible.
  • A few storms may develop Thursday afternoon southeast of I-35, although that probability is decreasing (20-40%).
  • Dry Friday, then turning wet again on Saturday. Temperatures look cooler late this week into early next week.

.DISCUSSION...
Issued at 248 PM CDT Wed Jun 10 2026

Broad cyclonic flow encompasses the Northern/Central Rockies and
Plains early this afternoon. One area of sfc low pressure is noted
in southeast CO extending into southwest KS, while another is
centered in western MN with a cold front extending into eastern NE.
On the mesoscale, there are two main areas to monitor for convective
initiation this afternoon. An outflow boundary from morning
convection in northern MO may help to focus the first storms in
northwest MO and far northeast KS. Additionally, convergence along
the sfc trough boundary may help to develop a few storms towards
central KS. Our area is right in between these two features. The 18z
RAOB had a little bit of MLCIN remaining with not much more surface
heating required to erode the cap. SPC mesoanalysis suggests 3000-
3500 J/kg of MLCAPE currently, with models suggesting 4000-4500 J/kg
with another hour or two of surface heating. Deep-layer shear is
sufficient for supercells as well. One challenge that remains is how
long any storms may remain discrete before cell interactions come
into play. There is a component of shear vectors that's parallel to
the boundaries, but not entirely. More recent HRRR runs have shown
better directional shear in the low levels with a more southerly sfc
wind compared to earlier, resulting in better low-level shear this
afternoon as well. As such, tornadoes will remain a potential threat
with any storms as long as they remain discrete. Large hail and
damaging wind continue to be the main severe hazards with either
supercells or multicell clusters after storms interact with each
other. Pwat remains high, so these storms should be efficient
rainfall producers with heavy downpours. 12z CAMs and HRRR runs
thereafter have been fairly consistent in only isolated areas seeing
amounts greater than an inch, and the 90th percentile of the HREF
supports this idea as well. With this in mind, would not rule out
some localized flooding if a storm stays over the same area for a
long time, but think this threat looks too isolated to support a
flood watch across a large area.

Storms should diminish towards/after sunset as inhibition increases
and the sfc low to our southwest deepens, which pushes the sfc
boundaries to our north. A second round of storms is favored to
remain north of our area in Nebraska, which is where the better
forcing is with the nose of the LLJ and approaching cold front.
Heading into Thursday, the frontal boundary moves across the area
and has been trending faster. Much of the guidance now has this
almost entirely through our area by 21z Thursday. This presents a
low probability for storms to develop southeast of I-35 in the
afternoon, though some guidance suggests we may miss this round
entirely.

Friday brings a drier and cooler air mass, leading to a quieter day
with highs in the 80s and sfc high pressure overhead. This is short-
lived, however, as southerly low-level flow returns moisture into
the area with zonal flow aloft as we sit between ridging to our
south and troughing to our north. A mid-level perturbation should
trigger another round of showers and storms during the afternoon and
evening. The exact area of greatest risk will depend on where the
sfc frontal boundary sets up, but will need to monitor once again
for flooding concerns with high Pwat and potential for severe
weather. The boundary looks to sag south for Sunday, lowering rain
chances but still keeping the baroclinic zone close enough to
justify some chance PoPs for the area.

Northwest flow aloft takes shape early next week. While rain chances
are less certain, this should usher in a much cooler and drier air
mass than we've seen recently, bringing highs down into the 70s and
dew points in the 50s!

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 625 PM CDT Wed Jun 10 2026

Storms have developed just northwest of MHK, so will maintain timing
of TS there, but have adjusted timing to be about an hour later at
TOP/FOE based on current radar and satellite trends. Otherwise,
expect southerly winds to increase overnight and remain gusty
through the day Thursday. A cold front will switch winds to the
northwest around midday. VFR conditions are expected outside of any
impacts from TS this evening.
