Areas affected...West-central Nebraska...Northwest Kansas

Concerning...Severe Thunderstorm Watch 619...

Valid 120047Z - 120245Z

The severe weather threat for Severe Thunderstorm Watch 619
continues.

SUMMARY...A threat for isolated large hail and severe wind gusts
will likely continue for an hour or two, before beco*ing marginal.
No additional weather watch issuance is expected.

DISCUSSION...Mosaic radar imagery shows scattered to widely
scattered strong to severe storms located from north-central
Nebraska into far northwest Kansas. The storms are located to the
east of an axis of moderate instability, where the RAP has MLCAPE in
the 1000 to 2000 J/kg range. This, co*bined with moderate deep-layer
shear, evident on regional WSR-88D VWPs, will continue to be
favorable for severe storms over the next couple of hours. Severe
wind gusts and isolated large hail will be the primary threats.
However, the storms will move eastward into the central Plains,
where instability is weaker and a capping inversion is present. This
will result in a gradual weakening trend during the mid to late
evening.
