    Mesoscale Discussion 1016

    0235 AM CDT Sun Jul 08 2018

    Areas affected...Portions of North Dakota and northwest Minnesota

    Concerning...Severe Thunderstorm Watch 264...

    Valid 080735Z - 080900Z

    The severe weather threat for Severe Thunderstorm Watch 264
    continues.

    SUMMARY...Strong/severe storms, primarily accompanied by gusty,
    damaging winds, may persist downstream of Watch 264. Trends are
    being monitored for possible new watch issuance. Such a watch would
    be needed around 3-330am CDT.

    DISCUSSION...A small cluster of occasionally severe cells is lifting
    northeast around 40 kt across central North Dakota this morning.
    These cells appear to be focused by forward propagation within a
    narrow buoyancy-gradient corridor along a surface front extending
    into far northwest Minnesota. Nocturnal cooling and related
    boundary-layer stabilization have fostered considerable convective
    inhibition ahead of these cells. However, forced ascent along the
    cold pool and residual steep lapse rates above the surface stable
    layer continue to yield a few vigorous updrafts, and these cells may
    remain capable of damaging gusts (due to the shallow nature of the
    stable layer). As such, convective trends associated with this
    cluster (as well as any new development downstream) are being
    monitored for possible new watch issuance.
