   Concerning...Severe Thunderstorm Watch 494...

   Valid 012151Z - 012315Z

   The severe weather threat for Severe Thunderstorm Watch 494
   continues.

   SUMMARY...Convection should continue increasing across the northern
   High Plains this evening.

   DISCUSSION...Mid-level short-wave trough is currently progressing
   across eastern MT/WY, per latest water-vapor imagery. Notable
   synoptic front has now surged across western ND, arcing through
   western SD into central WY. Scattered robust convection has evolved
   along this boundary and the strongest storms are now growing upscale
   as larger clusters begin to emerge. Over the next few hours there is
   increasing confidence that a corridor of significant convection will
   materialize from Bennett County SD to east of Mobridge, coincident
   with a pre-frontal axis of higher buoyancy.
