Areas affected...Parts of east central Kansas into west central
Missouri
Concerning...Severe Thunderstorm Watch 314...
Valid 252013Z - 252215Z
The severe weather threat for Severe Thunderstorm Watch 314
continues.
SUMMARY...Thunderstorm activity may continue to intensify and
consolidate near or south through southeast of the Kansas City area
between now and 6-7 PM CDT, accompanied by increasing potential for
strong surface gusts.
DISCUSSION...Thunderstorm development remains mostly discrete in
nature, but increasing in number, focused within/just to the warm
side of the zone of stronger differential associated with a remnant
outflow boundary. This currently extends just east of Hutchinson
into the vicinity of an outflow boundary intersection, south of the
Kansas City area, where it appears that convection may begin to more
substantively merge/consolidate through 22-00Z. Aided by inflow of
very moist boundary-layer air characterized by CAPE in excess of
3000 J/kg, considerable further convective intensification and
upscale growth appears probable.
Although mid-level flow may have weakened some during the past few
hours, vertical shear may be sufficient to contribute to
organization. Regardless, given the magnitude of CAPE, latent
heating in lower/mid-levels could still contribute to the evolution
of a mesovortex, strengthening rear inflow and increasing potential
for strong surface gusts near/south through southeast of the Kansas
City area by early evening. There may be a tendency for strongest
activity to begin to propagate southeastward along a remnant outflow
boundary toward areas near/northwest of the Lake of the Ozark
vicinity thereafter.
