    Areas affected...East-central MN...Northwest WI...Western Upper MI

    Concerning...Severe Thunderstorm Watch 393...394...

    Valid 270141Z - 270315Z

    The severe weather threat for Severe Thunderstorm Watch 393, 394

    SUMMARY...The threat for hail and damaging wind continues with
    ongoing thunderstorm cluster. Watch issuance downstream is possible
    by 02-03Z if the short-term intensity of this cluster is maintained.

    DISCUSSION...At 0130Z, a long-lived thunderstorm cluster is
    approaching northwest WI from northeast MN. While MLCINH will
    increase with time across the region, the intensity of this cluster
    may be maintained into a larger portion of northwest WI, where
    somewhat stronger heating occurred earlier in the day and the
    environment may still support near-surface-based updrafts for
    another 2-3 hours. Even if the system becomes somewhat elevated,
    MUCAPE in excess of 1500 J/kg and effective shear of 40+ kt will
    continue to favor organized storm structures through the evening.=20

    Recent radar trends indicate that the cluster is taking on more of a
    linear mode as the system accelerates southeastward. As a result,
    the primary threat may be transitioning to damaging wind, though
    some hail remains possible with the strongest embedded cores. New
    watch issuance downstream is possible by 02-03Z if the short-term
    intensity of the cluster is maintained this evening.
