.DISCUSSION...
Issued at 324 PM CDT Sun Apr 26 2026

Currently there is an upper shortwave moving into the Central
Rockies. This shortwave will continue to move east and likely eject
into KS late tonight to early hours of Monday morning. At the
surface, a warm front is over eastern KS and extends down into
western OK with an additional warm front stretched across southern
Oklahoma. Severe storms are actively pushing through eastern
KS. Portions of central and south-central KS continue to see low
clouds and patchy fog. As we move into later this afternoon and
evening, clouds will start to clear in northern OK and into
southern KS as the warm front across southern OK continues to
push north. Instability will increase to values between
2500-3000+ J/kg as moisture advection persists. This instability
combined with around 50 kts of effective shear and mid-level
lapse rates around 7.5 C/km are sufficient for additional severe
storm development with potential to be surface based. Large to
very large hail will be possible along with damaging winds and a
potential tornado given the increasing low-level SRH with this
threat mainly across southern and southeast KS. Then as the
upper wave approaches later tonight, additional elevated
convection will be possible. Destabilization is expected to
continue combined with increased 0-6km bulk wind shear over
50kts, and very steep mid-level lapse rates. This activity would
mainly be a hail threat across northern KS into central KS and
is anticipated to continue to move into northeast KS during the
overnight to early morning hours of Monday.

Showers and storms could linger into Monday morning in northern KS
and northeast KS with drier air moving in behind a cold front late
Monday afternoon. Rich moisture looks to stay well south of our area
through Wednesday, resulting in a break of active weather to start
the week. Flow aloft will shift to more zonal by Monday night and
likely continue through much of the work week. Rain chances may
return to the forecast late Wednesday night into Thursday as model
soundings hint at elevated showers. Strong to severe thunderstorms
are not anticipated given the limited instability. Mild temperatures
are progged through most of the week with high temperatures closer
to normal with much of the area seeing highs in the upper 60s and
70s.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1223 PM CDT Sun Apr 26 2026

MVFR to IFR conditions expected through much of the forecast
period due to low cigs and reduced vis. Scattered thunderstorms
will develop and impact much of the forecast area starting after
02Z and lasting through 08-10Z. Ceilings may lift some during
thunderstorm activity, but IFR/LIFR ceilings will continue into
Monday morning. Ceilings will begin to lift and clear after 12Z.
