Areas affected...Northeast Kansas to northwest Missouri

Concerning...Severe potential...Watch unlikely=20

Valid 120336Z - 120500Z

Probability of Watch Issuance...5 percent

SUMMARY...An isolated severe hail risk may persist across northwest
Missouri into northeast Kansas for the next 1-2 hours; however,
long-term trends should favor destructive storm interactions and an
overall weakening trend. Watch issuance is not expected.

DISCUSSION...Ongoing thunderstorms across the broader Kansas City
region have had a history of producing severe hail (up to 1.75
inches) over roughly the past hour. While individual storm longevity
has been fairly limited, deep convection continues to develop along
the south/southwestern flank of the convective outflow.
Additionally, new convective towers are noted to the northwest into
northeast KS as a weak mid-level perturbation pivots into the
region. Modest deep-layer shear (around 25-30 knots) is expected to
continue to limit storm longevity/organization, and storm
motions/propagation to the south/southeast along the developing
initiation axis should favor upscale growth and destructive storm
interactions with time. However, prior to upscale growth more
discrete, intense updraft pulses may realize the moderately unstable
air mass (2000-2500 J/kg MLCAPE based on the 00Z TOP sounding and
recent RAP mesoanalysis estimates) and continue to support a
sporadic severe hail threat within a narrow corridor from northeast
KS to northwest MO.
