Areas affected...southwest South Dakota into western and northern
Nebraska

Concerning...Severe Thunderstorm Watch 573...574...

Valid 310251Z - 310515Z

The severe weather threat for Severe Thunderstorm Watch 573, 574
continues.

SUMMARY...Numerous storms producing strong wind gusts and hail
should persist over much of southwest South Dakota into west-central
Nebraska.

DISCUSSION...Numerous storms and outflows have generally congealed
from southwest SD into northwest NE, with mixed storm modes
including cells propagating along outflows and splitting cells. 00Z
soundings show generally weak winds below 500 mb, and this may be
contributing to relatively slow progression of the storm clusters.
These storms are expected to continue processing the unstable air
mass and gradually shift southeastward. At this time, most of the
storms are well contained within the existing watches. Local
extensions may be considered in the short term as storms approach
the eastern parts of the watches.
