Areas affected...south-central and southeastern Missouri into
northern Arkansas

Concerning...Tornado Watch 311...

Valid 260603Z - 260800Z

The severe weather threat for Tornado Watch 311 continues.

SUMMARY...Storms continue moving eastward across central and
southern Missouri and now, portions of far northwestern Arkansas --
within WW 311.  As storms continue eastward, new WW issuance is
anticipated.

DISCUSSION...Latest radar loop shows strong/locally severe storms,
including a pair of supercells (one crossing Polk and Dallas
Counties in Missouri and the other over Delaware County Oklahoma and
moving into Benton County Arkansas), moving eastward into/across the
Ozarks area.  Downstream from these storms, RAP-based objective
analysis shows a favorably unstable airmass to the southwest of a
warm front that roughly bisects Missouri from northwest to
southeast.  Given the available warm-sector airmass, and favorably
strong/veering flow with height indicated across this region, it
would appear that severe risk will continue to expand downstream
from WW 311 over the next 1 to 2 hours, likely warranting new WW
issuance.
