region later tonight as an upstream cold front approaches from the

northwest, with a damaging wind and some tornado risk continuing

overnight.



The tornado watch area is approximately along and 60 statute miles

north and south of a line from 65 miles west northwest of Hot

Springs AR to 40 miles east of Poplar Bluff MO. For a complete

depiction of the watch see the associated watch outline update
