sporadic hail are the main concerns.  One or two convective

complexes may evolve and shift southeastward into southern parts of

the watch area tonight with a locally maximized wind-damage threat

as well.



The severe thunderstorm watch area is approximately along and 65

statute miles north and south of a line from 25 miles southwest of

Goodland KS to 20 miles north northeast of Kirksville MO. For a

complete depiction of the watch see the associated watch outline

update (WOUS64 KWNS WOU8).

REMEMBER...A Severe Thunderstorm Watch means conditions are
