Areas affected...portions of southeastern MO...and northeast AR.
Concerning...Tornado Watch 320...
Valid 262357Z - 270100Z
The severe weather threat for Tornado Watch 320 continues.
SUMMARY...Ongoing cluster of supercells with a history of producing
tornadoes will continue eastward with a risk for strong to intense
tornadoes.
DISCUSSION...As of 2350 UTC regional radar analysis showed a cluster
of supercells ongoing across southeastern MO within PDS Tornado
Watch #320. Several of these storms have produced tornadoes over the
past couple of hours. The environment ahead of these storms is
strongly unstable with MLCAPE greater than 4000 J/kg which is very
favorable for intense updrafts. Large ambient vorticity and enhanced
low-level shear (ESRH >200 m2/s2) is present along a modified
outflow boundary from southeast MO into northern AR and western
TN/KY, supporting the potential for strong low-level mesocyclones.
With STP values greater than 4, these storms will likely remain
capable of strong to potentially intense tornadoes this evening.
Eventual upscale growth is possible, but a significant tornado risk,
along with very large hail and damaging winds remains likely for the
next couple of hours.
