Areas affected...southeast Kansas...southwest Missouri...northeast
Oklahoma and northwest Arkansas
Concerning...Severe Thunderstorm Watch 358...
Valid 150923Z - 151030Z
The severe weather threat for Severe Thunderstorm Watch 358
continues.
SUMMARY...Storms moving through northeast Oklahoma into southwest
Missouri are approaching the eastern edge of WW 358. Locally strong
but mostly sub-severe wind gusts remain possible along portions of
this line next hour or so. However, overall threat is expected to
remain too marginal for another WW. Remaining portions of WW 358 and
357 can be canceled prior to expiration time.
DISCUSSION...Thunderstorms developing along leading gust front from
southwest MO to northeast OK continue to undergo a weakening trend,
likely due to the effects of strong convective inhibition. Mesoscale
and convective-scale forcing associated with a convectively induced
MCV and convergence along the gust front will likely maintain the
MCS into MO and northern AR. While locally strong wind gusts remain
possible along portions of this line, the hostile thermodynamic
environment will likely limit the potential for organized severe
storms.
