Areas affected...portions of southern and western Nebraska...and
adjacent northeastern Colorado/northern Kansas

Concerning...Severe Thunderstorm Watch 188...

Valid 060045Z - 060245Z

The severe weather threat for Severe Thunderstorm Watch 188
continues.

SUMMARY...Severe weather potential with isolated supercell storms
will continue over the next couple of hours across southern and
western Nebraska and nearby areas.  Large hail, and a few damaging
gusts locally, remain the most likely threats.

DISCUSSION...Latest radar loop shows a few isolated, rotating storms
moving northeastward across southwestern Nebraska/eastward across
south-central Nebraska, north of a northern Kansas surface warm
front.  The storms are occurring on the northern fringe of a Plains
instability axis, and within a favorable kinematic environment owing
in part to the low-level easterly/southeasterly winds on the cool
side of the warm front.  With west-southwesterlies aloft, the
overall wind field supports continuation of rotating storms, and
thus ongoing risk for large hail and damaging winds locally over the
next couple of hours.

As low-level southerlies/south-southwesterlies increase this
evening, an expansion in storm coverage -- with some upscale growth
-- is expected, with a possible ramp-up in severe potential during
the mid evening time frame.  Eventually however, diurnal
cooling/stabilization effects should act to temper ongoing risk,
which should gradually diminish into the overnight hours while
spreading eastward across Nebraska.
