The severe weather threat for Severe Thunderstorm Watch 284
SUMMARY...Gusty winds remain possible with convection.
DISCUSSION...Very weak short-wave trough is ejecting northeast
across the Dakotas late this evening. The southern-most influence of
this feature appears to be aiding convection across south-central
SD, along with a 25-50kt LLJ that extends across central NE into
this cluster. This activity does not appear to be particularly
robust, but 44kt wind gust was observed in the last 30 minutes at
KICR. Gusty winds may continue to be noted ahead of this cluster as
it spreads northeast.
