    Concerning...Severe Thunderstorm Watch 267...

    Valid 082246Z - 090045Z

    The severe weather threat for Severe Thunderstorm Watch 267
    continues.

    SUMMARY...A threat for severe wind gusts, large hail, and a tornado
    or two -- particularly across southeast North Dakota -- continues
    within WW 267.

    DISCUSSION...Over the last hour storm coverage and intensity have
    increased within WW 267. Latest surface analysis shows an outflow
    boundary positioned from Becker County, MN southwest to LaMoure
    County, ND where it intersects with a slow moving cold front. Very
    strong surface heating across much of the WW has contributed to
    2000-3500 J/kg MLCAPE. With 35-50 kts of effective deep-layer shear,
    storms should remain organized with a threat for severe wind gusts
    and severe hail. A threat for a tornado or two will also be possible
    over southeast North Dakota into parts of west-central Minnesota. In
    that region, the presence of the outflow boundary -- contributing to
    200+ m2/s2 of effective SRH -- along with favorable alignment of
    instability and deep-layer shear will maximize tornado potential.
