Areas affected...Parts of central North Dakota

Concerning...Severe Thunderstorm Watch 653...

Valid 240220Z - 240345Z

The severe weather threat for Severe Thunderstorm Watch 653
continues.

SUMMARY...The severe hail/wind risk continues spreading
southeastward across parts of central North Dakota tonight. While a
downstream watch is not expected, a local spatial extension of
Severe Thunderstorm Watch 653 may be warranted.

DISCUSSION...Latest radar data from KBIS shows a well-established
right-moving supercell cluster tracking southeastward
along/immediately south of a northwest/southeast-oriented baroclinic
zone draped across central ND. The primary concern with this
activity continues to be large hail and locally severe gusts. A
long/mostly straight hodograph (around 50 kt of effective shear per
00Z BIS sounding) and the focused baroclinic zone may support the
maintenance of this storm cluster in the near-term despite
increasing nocturnal boundary-layer static stability. Therefore, a
local spatial extension of Severe Thunderstorm Watch 653 may be
warranted given a continued risk of large hail and locally severe
winds.
