   0530 PM CDT Wed Jun 07 2017

   Areas affected...portions of northwest Minnesota

   Concerning...Tornado Watch 306...

   Valid 072230Z - 072330Z

   The severe weather threat for Tornado Watch 306 continues.

   SUMMARY...The tornado threat has largely ended across portions of
   northwest Minnesota. Tornado Watch 306 will expire at 23z.

   DISCUSSION...A weakening trend has been noted on radar observations
   over the last hour as a line of storms continues to track east
   across northwestern MN. Increasing boundary layer stabilization with
   loss of daytime heating will continue to stabilize the boundary
   layer. Additionally, weak instability with MLCAPE values around
   250-500 J/kg will further limit robust convection into the evening
   hours. Given the decreasingly favorable environment, a downstream
   watch is not expected and WW 306 will expire at 23z.
