Concerning...Severe Thunderstorm Watch 56...

Valid 160414Z - 160615Z

The severe weather threat for Severe Thunderstorm Watch 56
continues.

SUMMARY...Isolated damaging wind risk continues with progressive
squall line. However, a new watch is not currently anticipated.

DISCUSSION...Strongly forced band of pre-frontal convection is
propagating northeast across northeast IN/southern Lower MI and
extreme northwest OH. Boundary layer air mass has gradually
recovered into southeast MI over the last few hours which is
contributing to weak buoyancy, immediately ahead of this convection.
However, updrafts appear to be weakening a bit as lighting with the
northern portions of the squall line is decreasing, and the linear
nature of this activity is becoming more diffuse with time. Given
the current trends a new watch is not currently anticipated.
