    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.
