    Areas affected...Portions of Lower MI

    Concerning...Severe Thunderstorm Watch 358...

    Valid 290020Z - 290115Z

    The severe weather threat for Severe Thunderstorm Watch 358
    continues.

    SUMMARY...Mainly a strong to damaging wind threat continues across
    WW 358, although a tornado or two may also occur in the short term.

    DISCUSSION...A broken line of thunderstorms is moving eastward
    around 35-45 kt across much of Lower MI as of 0020Z. The airmass
    downstream of this convection remains weakly to moderately unstable,
    and 40-50 kt of effective bulk shear will likely support continued
    maintenance of these storms for at least the next couple of hours.
    Given the linear mode of the ongoing thunderstorms, strong to
    locally damaging winds should be the primary threat. 00Z sounding
    from Gaylord, MI show some veering/strengthening winds in the low
    levels, with measured effective SRH of 178 m2/s2. An embedded
    circulation within the line with a TDS signature occurred around
    2355Z in eastern Antrim County MI. Accordingly, another tornado or
    two cannot be ruled out in the short term (mainly across northern
    Lower MI in the vicinity of a front) given the low-level shear
    present ahead of the line.
