   Concerning...Severe Thunderstorm Watch 441...

   Valid 160144Z - 160315Z

   The severe weather threat for Severe Thunderstorm Watch 441
   continues.

   SUMMARY...Isolated strong/severe thunderstorms remain possible
   across portions of northern Minnesota; however, overall threat
   appears marginal.

   DISCUSSION...Pre-frontal convection has struggled to develop, much
   less organize, across northern MN this evening. With boundary layer
   now cooling across this region, surface-based buoyancy is beginning
   to lessen. 00z sounding from INL exhibits sufficient surface-6km
   bulk shear for potential supercells; however, low-level convergence
   appears to be inadequate for more than isolated, marginally severe
   convection. Overall trends do not appear favorable for upscale
   growth.
