Weather hazards expected...

  Limited Hail risk.
  Limited Flooding risk.
  Significant Lightning risk.

DISCUSSION...

Showers and thunderstorms and the risk for cloud to ground
lightning will increase overnight across southeastern Kansas and
the Missouri Ozarks. There will be the potential for thunderstorms
to train over the same locations across portions of western
Missouri and southeastern Kansas. This will result in at least a
limited risk for flash flooding.

In addition to the threat for flooding, there is the potential for
a few storms to produce hail up to the size of quarters across
southwestern Missouri and southeastern Kansas.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.

Additional showers and thunderstorms will be possible over several
days from mid to late week.

.SPOTTER INFORMATION STATEMENT...

  Spotter activation will not be needed through tonight.
