Areas affected...Southern Lower Michigan
Concerning...Tornado Watch 113...
Valid 150403Z - 150500Z
The severe weather threat for Tornado Watch 113 continues.
SUMMARY...Threat for embedded tornadoes and swaths of wind damage
will persist across southern and southeastern Lower Michigan through
05-06z.
DISCUSSION...Radar imagery suggests the formation of a larger
MCV/comma head structure in southeast Lower MI with persistent
convection. Embedded mesovortices have been observed within the
comma head, and a swath of likely damaging winds extends south of
the comma head/MCV. The tornado and wind threat are likely to
persist for the next couple of hours while the convection develops east-southeastward along the buoyancy gradient, in a zone of strong
low-level flow/shear.
Farther west into southwest Lower MI, the threat for
mesovortices/tornadoes will persist where a N-S bowing segment moves east-southeastward and intersects a more E-W outflow segment near
the borders of Barry/Eaton and Kalamazoo/Calhoun Counties.
