Areas affected...Ohio Valley
Concerning...Tornado Watch 196...197...198...199...
Valid 080220Z - 080315Z
The severe weather threat for Tornado Watch 196, 197, 198, 199
continues.
SUMMARY...Scattered severe thunderstorms will sag southeast across
the OH Valley this evening.
DISCUSSION...Scattered severe thunderstorms, including isolated
supercells and short-line segments, arc from central OH-southern
IN-extreme southeast IL. This activity is propagating slowly
southeast along the northern fringe of greater buoyancy. As the LLJ
increases across the upper OH Valley later this evening, a more
eastward shift is expected toward the PA border, though air mass is
notably less unstable immediately downstream within this
warm-advection corridor. Several long-lived supercells persist, and
given the shear, will likely continue, especially from southern IN
into southern OH.
