Areas affected...Southwestern Missouri

Concerning...Tornado Watch 34...

Valid 180045Z - 180145Z

The severe weather threat for Tornado Watch 34 continues.

SUMMARY...The severe threat across WW34 will continue but gradually
decline through this evening. Trends will be monitored but a
downstream watch appears necessary.

DISCUSSION...A cluster of severe thunderstorms with a history of
producing large hail and a tornado will continue east over the next
1 to 2 hours. A general downtrend in convective intensity has been
noted over the last hour consistent with the loss of diurnal heating
and a shifting of large scale ascent away from the ongoing
convection. WW34 has been locally extended until 0200 UTC to account
for the remaining threat. Downstream of the storm cluster, buoyancy
weakens with temperatures in the low 60s F suggesting minimal threat
exists farther east. A downstream watch appears unlikely at this
time but, severe weather, including strong wind gusts and a tornado
or two, will remain possible for the next couple of hours.
