    Areas affected...Western North Dakota

    Concerning...Severe Thunderstorm Watch 248...

    Valid 090135Z - 090300Z

    The severe weather threat for Severe Thunderstorm Watch 248
    continues.

    SUMMARY...Gusty winds and hail remain likely with the strongest
    storms.

    DISCUSSION...Long-lived MCS cluster that has propagated west across
    ND has forced an outflow boundary across ww248 into eastern MT.
    Substantial cold pool from this MCS has contributed to quite gusty
    southeast winds, at times speeds in excess of 50kt, well west of the
    original precip shield. This may continue for a few more hours
    before convection spreads from west to east across the watch. Hail
    may accompany this eastward-moving activity before it weakens as it
    encounters cooler, less buoyant air mass downstream.
