.DISCUSSION...
Issued at 311 AM CDT Tue Apr 28 2026

Current surface analysis shows stalled out frontal boundary near the
Red River region with very rich gulf moisture along and south of the
boundary. Meanwhile satellite imagery shows upper level wave near
the 4 corners region and a second wave over southern Idaho. Both of
these waves will continue to move east across the Rockies and phase
together across Nebraska today. This will cause the stalled out
frontal boundary to lift northward across Oklahoma as a warm
front. Already seeing signals of elevated moisture transport
spreading north of the surface front on satellite low-level
water vapor imagery early this morning across west Texas
into southwest Oklahoma. This signal will translate northeast
and cause elevated storms to blossom over central Oklahoma this
morning. A few storms could possibly expand further north into
parts of far southeast Kansas by late this morning through mid
afternoon where CAM model trends are highlighting. The elevated
environment would become favorable for strong to severe storms
to materialize given steep mid-level lapse rates, MUCAPE
1000-2000j/kg, and 1-6km bulk shear around 50kts in the
vicinity. The primary hazard would be large hail of quarter to
possible golf ball size in this type of environment. Additional
rain showers are possible over central Kansas just ahead of the
upper wave which will be further removed from the better quality
moisture. Dry weather will prevail for tonight and Wednesday as
subsidence overspreads the region in the wake of today's upper
level wave.

Thursday-Monday

Models continue to show a second upper level wave dropping southward
across the northern plains inducing mid-level lift over western
Kansas on Thursday. This will generate mainly rain showers with a
few embedded weak storms possible. Some of this activity could
venture eastward into central Kansas on Thursday. Severe weather is
not expected due to very low elevated instability and poor mid-level
lapse rates. Weather pattern looks to remain dry for Friday into the
weekend along with temperatures warming each day.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1243 PM CDT Tue Apr 28 2026

Some MVFR ceilings are lingering over parts of central and parts
of southeast Kansas. Elevated storms are also tracking into
southeast Kansas but this activity is expected to remain south
and east of the Chanute terminal, mainly impacting Labette
county or areas along and southeast of a line from Coffeyville
to Altamont to Labette. The storm activity is expected to exit
the area by mid-afternoon with VFR prevailing thereafter. Light
northeast winds will prevail through the period.
