Areas affected...parts of central through southwestern
Missouri...adjacent southeastern Kansas and northeastern Oklahoma

Concerning...Tornado Watch 130...131...

Valid 172210Z - 180015Z

The severe weather threat for Tornado Watch 130, 131 continues.

SUMMARY...Potential for damaging surface gusts and perhaps brief
tornadoes may increase through 6-8 PM CDT across the Missouri Ozarks
and much of central Missouri. Additional counties between Tornado
Watches 130 and 131 will need to be added Tornado Watch 130.

DISCUSSION...Although a trailing line of storms may tend to become
increasingly undercut by the southeastward advancing cold front, a
cluster of storms east/northeast of Chanute is now evolving just
ahead of the front. This appears to be aided by forcing for ascent
associated with a mid/upper subtropical perturbation/jet streak
which is forecast to overspread the Missouri Ozarks through much of
central Missouri into early evening. Embedded within sheared 30-50
kt southwesterly deep layer mean flow, and preceded by a moist
boundary-layer that appears characterized by CAPE up to 2000 J/kg,
there appears potential for considerable further upscale growth and organization, which probably will outpace the eastward advancement
of the cold front.

Gradually, this may be accompanied by a developing meso-beta to
alpha scale cyclonic circulation and related strengthening of
mid-level rear inflow. As this mixes to the surface, potential for
damaging wind gusts will increase, with strongest gusts and/or brief
tornadoes focused with evolving mesovortices along the gust front.
