Areas affected...far northern Kansas...much of southern
Nebraska...southwest Iowa and far northwest Missouri

Concerning...Severe potential...Watch likely=20

Valid 052055Z - 052300Z

Probability of Watch Issuance...80 percent

SUMMARY...Storms will develop from far northern Kansas across much
of southern and eastern Nebraska after about 22-23Z. Damaging winds
and hail will be possible.

DISCUSSION...Visible satellite shows CU development within the
surface trough over western KS and intersecting the stationary front
extending from southern NE into IA. Initial development is most
likely from northern KS into south-central NE in the next 1-2 hours,
with additional activity increasing along the stationary front as a
modest low-level jet increases this evening.

Localized hail at or above 2.00" may occur, along with an eventual
mixed-mode damaging wind threat as storms travel within the
moderately unstable zone near the boundary. Visible imagery and
surface observations show ample moisture in place, which is also
beneath steep midlevel lapse rates. Deep-layer shear is a bit
marginal for supercells, but deep-layer mean winds speeds as well as
the increasing southerly winds at 850 mb should support accelerating
eastward propagating clusters, and perhaps some cells splits.
