   enough in the relatively narrow, unstable warm sector near the warm
   front.  Damaging winds will also be possible, especially late this
   evening when storms could grow upscale into a squall line along the
   cold front approaching from the west.

   The tornado watch area is approximately along and 60 statute miles
   east and west of a line from 50 miles northeast of Yankton SD to 45
   miles south of Sioux City IA. For a complete depiction of the watch
