.DISCUSSION...
Issued at 211 PM CDT Sun Apr 26 2026

Cluster of storms that developed near Hays KS this morning has
continued to evolve into a bow echo racing across eastern KS.  Meso-
analysis from SPC suggests storms are building into increasingly
unstable environment with 1500-2000 J/kg of surface based CAPE with
~40 knots of 0-6 km bulk shear. As mid level winds increase through
the late afternoon hours, expect bulk shear to increase closer to 50
knots.  With storms becoming increasingly surface based as they
build into the area, expect increased wind threat. Warn on forecast
has increased the 1"+ hail threat across Linn KS ~21Z this afternoon
with southern end of the line, and a more widespread wind threat
increasing after 21Z ahead of the line.  Precipitable water is
running  in the neighborhood of 1.3", well above the 90th percentile
for this time of year.

After the initial line pushes east across the area, could see
additional development behind the line as additional mid level short
waves build east and 30-40 knot low level jet develops.  Inflow into
the region could be shifted a bit by potential outflow from initial
line of storms. HRRR has hinted at this potential over the last few
hours, leading to additional development and training of storms
along the I-70 to highway 50 corridors. Given this potential and
antecedent wet conditions, have expanded the flood watch to include
much of the forecast area tonight. Additional storms tonight could
be strong given the steep lapse rates from 800-700 mb (potentially
exceeding 8 degrees C/km) in combination strongly sheared
environment. Upper level divergence increases after 06Z tonight and
continues Monday morning as left exit region of upper level jet
noses into the area.  Overall, you can see trends in the models of
multiple rounds of storms overnight, but specific timing is
difficult to ascertain at this point.

Strongly sheared and unstable environment continues tomorrow morning
as warm front races north across the area.  As such, could see a
brief recovery in temperatures through the morning hours with
surface temperatures climbing into the 70s, but enviroment doesn't
appear to be all that strongly capped so could be looking at
potential for additional storms until cold front shifts through the
region in the late morning/early afternoon hours.

Cooler and drier conditions are expected much of the remainder of
the week, which are well needed.

.AVIATION /12Z TAFS THROUGH 12Z MONDAY/...
Issued at 633 AM CDT Sun Apr 26 2026

Isolated to scattered showers/storms possible this afternoon,
and fluctuating ceilings between low-end VFR and MVFR expected
as low pressure strengthens. Strong storms are expected to
develop in central Kansas later this afternoon, and eventually
congeal into a cluster of storms. These are likely to arrive
around the KS-MO state line between 00-03z. Additional
development is possible behind this. Ceilings will be low-end
MVFR, with down pours potentially resulting in periods of IFR
visibility.
