Areas affected...Parts of northeast Oklahoma through southwestern
Concerning...Tornado Watch 212...
Valid 230234Z - 230330Z
The severe weather threat for Tornado Watch 212 continues.
SUMMARY...Risk for tornadoes may continue another hour or two, risk
for severe wind and hail continues into the overnight hours.
DISCUSSION...Discrete supercell development persists within a narrow
pre-frontal corridor near Interstate-44, across northeastern
Oklahoma into southern portions of the Missouri Ozarks. This is
where low-level shear and boundary layer CAPE (supported by surface
dew points near 70f) remain maximized, and additional tornado
development may not be out of the question into the 03-04Z time
In general though, boundary-layer based storm development appears to
be gradually waning, but convection rooted above the boundary layer
is expected to persist, near/above the southeastward advancing
front, but along a 30-40 kt southwesterly 850 mb jet axis. This may
continue to be accompanied by a risk for severe hail and perhaps
some increase in potential for damaging wind gusts.
