.DISCUSSION...
Issued at 118 PM CDT Wed Jun 10 2026

A mid/upper trough remains over the Northern Plains today while a
couple of more subtle features evident on Water Vapor imagery
were rotating north and northeast of the area. At the surface,
a frontal boundary was bisecting Central Kansas while low level
flow was veered ahead of the front across the area. We see some
subtle 12-hr height rises over the Central Plains as we move
through the day as we remain on the southern periphery of the
stronger belt of mid-level flow. We are still expecting
isolated thunderstorms to develop along the frontal boundary and
as the LLJ ramps up this evening we could see some storms begin
to fill in along the front from northeast to southwest but a
capping inversion may build into southern Kansas limiting storm
coverage. Steep lapse rates/moderate to extreme buoyancy and
deep layer shear around 30 knots will support some organized
severe storms with large/very large hail, 70+ mph wind gusts,
and maybe a brief tornado or two as the LLJ ramps up in the
early evening hours. We continue to see a very moist column with
PWATs progged to rise to near 2 inches along/ahead of the
frontal zone leading to efficient rain with high rainfall rates
and potential flooding concerns. Once again, storms may struggle
to get organized over south central KS due to capping concerns.
The focus for storms tonight is expected to shift north and
east of the area as the frontal boundary gradually shifts over
the area into southeast KS early on Thu.

The front over southeast KS may become a focus for deep moist
convection across southeast Kansas on Thursday afternoon/early
evening before the focus shifts south and east of the area early in
the evening (or perhaps sooner). The cap may erode by 19/20Z across
the Flint Hills with a similar environment as today setting the
stage for another round of severe storms. The current thinking is
that linear mode will be favored with deep layer shear vectors
running parallel to the boundary and veered low level flow. We
continue to be in a high PWAT airmass with saturated soils in
southeast KS so heavy rain would likely result in a
continuation or additional flooding along the Neosho river.

Fri-Sat...We expect a break in the action on Friday as a stable post-
frontal regime builds over the area with seasonable temperatures
anticipated. This break may be short-lived as low level southerly
flow on the backside of the sfc high will begin to advect low level
moisture northward once again. A robust LLJ is progged to develop
Fri night with decent mid-level waa and we could see some storms
propagating eastward off the high plains or some elevated storms
redeveloping through the night and possibly backbuilding during the
day on Saturday. This could have implications on the potential for
severe weather on Sat with a large amount of uncertainty at this
time. A southward advancing cold front could still become a focus
for severe storms on Saturday PM but there remains some questions on
how Fri night/early Sat impacts this scenario.

Showers and storms may linger across the area on Sunday as we remain
in a mean large-scale trough over the central CONUS but confidence
in the details remains low as the frontal boundary may be forced
further south of the area leading to a stable post-frontal regime
over the Central Plains. Another shortwave wave trough may emerge
from the Rockies early in the week bringing another round of showers
and storms to the area. This will eventually lead to northwest flow
in the Tue-Wed periods as the mid/upper ridge amplifies over the
Rockies leading to mostly dry weather conditions and seasonable
temperatures toward the middle of the week.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 628 PM CDT Wed Jun 10 2026

Main aviation concern will be storms tonight.

Storms have started to develop across parts of central and
northeast Kansas along and southeast of a cold front. Through
03z, KSLN, and to a lesser extent, KGBD will be the sites most
likely affected. Any storm this evening will have the potential
to be severe with large hail and damaging winds possible. Front
will continue moving south and is expected to move through KHUT-
KSLN- KICT in the 15-17z time frame. Behind the front northwest
winds will gust in the 30-25kt range. As the front moves
through KCNU, a few storms will be possible in the 19-23z time
frame.
