   Areas affected...Northeast NE into northwest IA and extreme
   southeast SD

   Concerning...Tornado Watch 418...

   Valid 160047Z - 160215Z

   The severe weather threat for Tornado Watch 418 continues.

   SUMMARY...The tornado threat will continue through dusk, along with
   some potential for locally damaging wind and hail.

   DISCUSSION...A supercell cluster has evolved across northeast NE
   this evening, with multiple reports of confirmed tornadoes over the
   last 1-2 hours. The immediate downstream environment remains
   favorable for tornadic supercells, with MLCAPE in excess of 2000
   J/kg, backed surface winds, and rather strong low-level shear/SRH
   still noted in VWPs from KFSD and KOAX. Any persistent supercells
   will continue to pose a tornado threat through dusk within this
   environment, along with some isolated hail potential. With time,
   there is some potential for a small bowing segment to evolve out of
   the ongoing cluster, which could result in a somewhat greater threat
   for damaging wind as convection spreads into northwest IA, in
   addition to some continued tornado potential.
