   Areas affected...Parts of eastern North Dakota

   Concerning...Severe Thunderstorm Watch 625...

   Valid 250131Z - 250230Z

   The severe weather threat for Severe Thunderstorm Watch 625
   continues.

   SUMMARY...The risk of large hail and damaging wind gusts continues
   spreading eastward across parts of eastern North Dakota -- within
   Severe Thunderstorm Watch 625.

   DISCUSSION...Following several storm splits and associated mergers,
   a small upscale-growing cluster has evolved along the surface front
   in south-central/southeast ND. Over the next couple hours, this
   cluster will continue southeastward and pose the greatest risk of
   damaging wind gusts -- given the well-established cold pool and
   strong surface-based buoyancy downstream. Additionally, left-movers
   evolving northeastward in north-central SD could interact with this
   cluster and result in additional upscale growth. However, the 00Z
   ABR sounding sampled robust low-level inhibition at the base of the
   EML, which may limit the severe risk with southeastward extent into
   parts of northeastern SD. 

   Farther north, a separate convective cluster/left-mover is tracking
   northeastward across parts of northeastern ND. Around 45 kt of 0-6
   km shear (per MVX VWP data) oriented perpendicular to the surface
   front and moderate surface-based buoyancy should help maintain this
   cluster for the next hour or two. Large hail and damaging winds will
   be the main concern with this activity.
