   Valid 272303Z - 280030Z

   The severe weather threat for Tornado Watch 476 continues.

   SUMMARY...The severe threat continues across Tornado Watch 476. A
   few tornadoes remain possible with discrete supercells, but the
   severe wind threat should increase as an MCS overtakes the
   supercells in the next few hours.

   DISCUSSION...Two discrete supercells continue across southwestern ND
   as a well-developed MCS (with a history of severe gusts) approaches
   from southeastern MT. 22Z mesoanalysis shows modestly
   curved/elongated hodographs preceding the supercells, along with
   200-300 m2/s2 effective SRH, supporting tornado potential. With
   time, the fast approaching MCS from the west will merge with the
   supercells. This may augment the severe wind threat, with 75-90 mph
   gusts possible. QLCS tornadoes will still be a concern as well.
