MD 2032 CONCERNING SEVERE THUNDERSTORM WATCH 653… FOR PARTS OF CENTRAL NORTH DAKOTA
Mesoscale Discussion 2032
NWS Storm Prediction Center Norman OK
0920 PM CDT Wed Aug 23 2023
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.
