.DISCUSSION...
Issued at 109 PM CDT Sat Jun 13 2026

A cold front moving south across southern Nebraska early this
afternoon will provide a focus for showers and thunderstorms as we
move into the mid and especially late afternoon and evening hours
across much of the forecast area. Early morning showers and storms
were less numerous than anticipated yesterday and with abundant
insolation and continued low level moisture advection, we expect to
see strong buoyancy and moderate deep-layer shear supporting
large/very large hail with the initial development while gradually
transitioning to more of a linear mode as the front progresses
southward this evening with damaging winds and heavy rainfall.

We do see a couple of more pronounced outflow boundaries which could
impact the evolution of afternoon convection. One was building
southward into northeast/east central Kansas and another was
bisecting far southeast KS. These could result in some earlier
development which will also be capable of producing large hail
and damaging winds with a lower threat for tornadoes, especially
as we see a more deeply mixed pbl with relatively high LCLs.
Efficient rainfall is also anticipated as we remain within the
higher plume of PWATs leading to flooding concerns, especially
in southeast KS where antecedent conditions would support more
runoff.

The storm activity is expected to move south of the area shortly
after midnight while a stable post-frontal regime builds into the
area for Sunday-Monday leading to dry weather and seasonably cool
temperatures with highs mostly in the 70s.

Northwest mid/upper flow is progged across the area early in the
week which will help steer a shortwave trough over the Upper
Mississippi Valley area while a trailing frontal boundary moves into
the Central Plains. This front could become a focus for deep moist
convection on Tuesday afternoon. Modified Gulf moisture will be in
place with robust deep layer shear and increasing mid-level lapse
rates as we move into the afternoon hours. Widely scattered
strong/severe storms will be possible into the evening hours before
the activity races southward away from the area. Another shortwave
trough rotating over the Northern Plains on Wednesday could bring
another round of storms to the area while driving a cold front into
the Southern Plains. We may begin to see more influence from the
mid/upper ridge over the Southern Plains Thu-Fri with rising
temperatures as we remain in a stable post-frontal airmass.

Unsettled weather may return as we move into the beginning of the
weekend but confidence in the details remains rather low at this
time. Another frontal boundary may begin to approach from the north
late in the week becoming a focus for showers and thunderstorms
while seasonably mild temperatures are anticipated.

.AVIATION /00Z TAFS THROUGH 00Z MONDAY/...
Issued at 625 PM CDT Sat Jun 13 2026

Main aviation concern will be storms overnight.

Storms are currently ongoing across northeast and central KS
with these storms tracking off to the southeast along a strong
cold front. Storms will move through KSLN in the next hour or
two and KHUT-ICT in the 01-03z time frame. Lastly they will
affect KCNU in the 03-05z range. Damaging winds and large hail
will be likely with the stronger storms. Once the storms push
south of the area, VFR conditions and north winds are
anticipated through the remainder of the forecast.

604 PM CDT Sat Jun 13 2026

This hazardous weather outlook is for portions of central Kansas,
east central Kansas, south central Kansas and southeast Kansas.

.DAY ONE...Tonight

Thunderstorms across northeast and central Kansas will continue to
spread southeast across the region through the evening hours. Large
hail up to two inches in diameter and damaging winds of 60 to 80 mph
are the primary risks. There is a low chance of a few tornadoes
before the storms congeal into a line bringing increasing threats
for damaging winds and heavy rain. Locally heavy rain may result in
flash flooding, especially across parts of southeast Kansas where a
flood watch remains in effect.

Heat indices around 105 are possible across south-central Kansas
this afternoon. A Heat Advisory is in effect for this afternoon and
evening.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

A few strong or severe storms may be possible on Tuesday with
thunderstorm chances lingering into Wednesday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected tonight, but we would appreciate
any reports of severe weather.
