.DISCUSSION...
Issued at 111 PM CDT Sat Sep 19 2026

A cold front was bisecting northwest Kansas this morning while a
trough of low pressure extended SSW of this frontal boundary. As the
low level flow backs late this afternoon/early this evening we may
see some pooling of low level moisture allowing the cap to weaken
sufficiently. Scattered thunderstorms are expected to develop
along the frontal zone after 4 pm. Meanwhile, another hot day
is anticipated south of the front where a deeply mixed pbl is
expected once again. This deeply mixed pbl will become
moderately unstable with large DCAPE. Strong downdrafts are
likely with any storm that develops while the threat for large
hail appears slightly less favorable given modest mid-lvl lapse
rates. PWATs around 2 inches or above the 97th percentile will
support efficient rainfall with some localized flooding concerns
where training occurs. Another cluster of storms is expected to
develop across the Central High Plains this evening as the
mid/upper trough moves into the Northern Rockies. This cluster
may be aided by a developing LLJ nosing into central KS allowing
the storms to persist arriving across the area after midnight.
The frontal boundary is progged to become stationary across the
Flint Hills late tonight. As mid-lvl lapse rates steepen through
the night, we could still see a few lingering strong/severe
storms across the area.

Some showers and storms may be ongoing early in the day on Sunday
with considerable convective debris leading to little or reduced
insolation and temperatures were trended lower. The front will
become a focus for showers and storms once again as we move through
the day. An earlier onset appears likely which may limit the threat
for more widespread severe weather before the focus shifts south and
east of the area late in the day. Maintained some low pops into
Sunday evening with some lingering mid-lvl waa as the pv anomaly
moves across the area. Much cooler air will arrive in the wake of
the cold front while a slower fropa will result in another mild day
in parts of southern KS on Sunday.

Monday-Wednesday...a stable post-frontal regime is anticipated as we
move through the middle of the work-week with cool weather expected.
Afternoon highs are expected to top out in the 70s with lows in the
50s.

Thursday-Sunday...The mid/upper ridge is progged to reside over the
Southern Plains while nosing into the Central Plains as we move into
the latter portion of the week. This will allow temperatures to
begin to moderate with seasonably mild values anticipated. Flow
around this ridge may help steer some shortwave troughs toward the
area late in the week and into the weekend and some modest pops were
maintained through the period.

.AVIATION /00Z TAFS THROUGH 00Z MONDAY/...
Issued at 649 PM CDT Sat Sep 19 2026

Scattered showers and storms continue to make their way through
portions of the area this evening. A secondary round of storms may
arrive later tonight into early Sunday morning as a complex tracks
eastward out of western Kansas. Tried to time this out with PROB30
groups in central and south central KS, though subsequent AMDs will
likely be needed as radar trends evolve. Strong winds will be
the greatest concerns with these storms.

Additionally, lowering cigs/vsbys are expected late tonight into
early Sunday morning, particularly across central KS although these
could creep into portions of south central KS. For now, introduced
IFR at RSL/SLN/GBD and will AMD as timing becomes more evident.

Finally, a cold front tracking through the area has resulted in
gusty northerly winds behind it as observed at RSL. This
boundary will continue its push to the south and result in
northerly winds eventually becoming realized at all sites by
early Sunday morning.
