accompany any discrete supercells. A band of severe thunderstorms
is forecast to move west to east across the Watch area later this
evening. A risk for a tornado may exist with any supercell embedded
within the broken band. Severe gusts (60-80 mph) will be likely
with the more intense portions of the band of storms.

east and west of a line from 55 miles north northeast of Williston
ND to 60 miles south southwest of Dickinson ND. For a complete
depiction of the watch see the associated watch outline update
