Areas affected...Northeast/East-Central KS...Northwest/West-Central
MO

Concerning...Severe Thunderstorm Watch 690...

Valid 232041Z - 232215Z

The severe weather threat for Severe Thunderstorm Watch 690
continues.

SUMMARY...Threat for thunderstorms capable of large hail and
damaging gusts continues across Severe Thunderstorm Watch #690.

DISCUSSION...An outflow-reinforced boundary currently arcs from a
surface low over northeast KS eastward into west-central MO. Modest
low-level warm advection and moisture convergence persist in the
vicinity of this boundary, with recent visible satellite imagery
depicting an area of deeper cumulus development just north of OWI
(or about 35 miles southwest of OJC) in east-central KS. Overall
thermodynamic environment across the region remains supportive
additional development in the vicinity of this boundary,
particularly if low-level moisture convergence persists. Moderate
vertical shear supports organized storm structures, with the threat
for large hail and strong gusts persisting, particularly across
central and southern portions of Severe Thunderstorm Watch #690.
