Areas affected...Northeast SD

Concerning...Severe Thunderstorm Watch 647...

Valid 260350Z - 260515Z

The severe weather threat for Severe Thunderstorm Watch 647
continues.

SUMMARY...A localized damaging-wind threat may spread into northeast
South Dakota.

DISCUSSION...Persistent convection has evolved into a small
outflow-driven cluster moving across east-central SD, with some
increase in storm intensity and inbound radar velocities from KABR
recently noted. This cluster may continue to spread
north-northeastward, within a corridor of deeper low-level moisture,
stronger MLCAPE, and somewhat weaker MLCINH (as noted per recent RAP
analyses). Localized severe gusts may accompany this cluster through
late evening as it moves into northeast SD. Observational trends
will be monitored regarding the need for local watch expansion, if
this cluster remains organized to the edge of WW 647.
