    Areas affected...portions of Minnesota and western Wisconsin

    Concerning...Severe Thunderstorm Watch 135...

    Valid 232040Z - 232145Z

    The severe weather threat for Severe Thunderstorm Watch 135
    continues.

    SUMMARY...Strong to severe storms remain likely this afternoon and
    into the evening. Damaging winds and hail are probable. A couple of
    tornadoes remain possible.

    DISCUSSION...As of 2045 UTC, regional radar imagery showed a broken
    band of strong to severe thunderstorms had developed along
    progressive portions of the cold front across central MN. The
    environment downstream of these storms has slowly warmed into the
    low 70s despite persistent cloud cover. While buoyancy remains on
    the lower end, ~1000 J/kg MUCAPE, this should be sufficient for a
    few stronger updrafts as storms consolidate into a line. Damaging
    gusts and hail appear to be the most probable threats. Low-level SRH
    around 100-200 m2/s2 could support a couple of tornadoes with
    embedded supercellular structures or QLCS circulations. The severe
    threat should continue as the cold front continues eastward across
    WW135.
