Areas affected...portions of the Ozarks into central Arkansas

Concerning...Tornado Watch 284...

Valid 072058Z - 072230Z

The severe weather threat for Tornado Watch 284 continues.

SUMMARY...A couple of tornadoes and isolated damaging wind gusts
remain possible across Tornado Watch 284, with this severe potential
possibly extending farther south into central Arkansas.

DISCUSSION...Scattered thunderstorms remain ongoing from central
Missouri southward into central/southern Arkansas ahead of a
mid-level MCV analyzed over northeastern Oklahoma. Several areas of
transient, weak rotation have been noted with marginal supercell
structures over the past 1-2 hours, with a recent report of a brief
tornado in Newton County, Arkansas. While mid-level flow has
weakened some since 19z (per the SGF VAD profile), backed surface
winds across central/southern Missouri are maintaining 75-100 m2/s2
0-1 km SRH. Coupled with modest effective shear around 30 kts (per
latest objective analysis), this will continue to support the
potential for marginal supercells and a couple of tornadoes across
Tornado Watch 284 for at least another 1-2 hours.

Farther south into central Arkansas, modestly weaker low-level shear
and more veered surface winds should yield somewhat reduced tornado
potential; although, a brief tornado cannot be ruled out. High PWAT
content (2+ inches) continues to promote a risk for localized
damaging downburst winds.
