Areas affected...Northern Ohio

Concerning...Severe Thunderstorm Watch 226...

Valid 052256Z - 060030Z

The severe weather threat for Severe Thunderstorm Watch 226
continues.

SUMMARY...A line of thunderstorms migrating into northwestern parts
of WW 226 may produce strong to severe winds and isolated hail,
though it is not clear how long or far downstream this threat will
persist.

DISCUSSION...Reflectivity and velocity data from KCLE shows an
organized, but compact, convective band developing across
central/north-central OH. Wind velocities between 1-1.2 km above
radar level were recently sampled at 35-45 knots, which suggests
winds capable of producing damaging winds are likely embedded within
the band. Environmentally, this line is on the periphery of any
appreciable buoyancy and continues to migrate away from the better
low-level moisture. However, a 35 knot 0-3 km wind shear vector
sampled by the nearby KCLE VWP is nearly orthogonal to the line, and
strong ascent associated with a vorticity maximum/shortwave trough
aloft will continue to provide ascent and some degree of mid-level cooling/destabilization in the vicinity of the line. Consequently,
this line may pose a damaging/severe wind and isolated hail threat
into north-central OH. Eventually, diminishing buoyancy with
northwest extent will lead to the demise of the band so downstream
watch issuance is not expected (though local watch expansions have
been made), but exactly when this occurs remains somewhat unclear.
