    Areas affected...Eastern Montana

    Concerning...Severe Thunderstorm Watch 247...

    Valid 090015Z - 090145Z

    The severe weather threat for Severe Thunderstorm Watch 247
    continues.

    SUMMARY...Severe threat will focus across northern and eastern
    portions of the watch over the next 1-2 hours.

    DISCUSSION...Notable mid-level short-wave trough has translated
    across the Great Basin into northwestern WY/south-central MT as
    evident by an arcing band of weak high-based convection that extends
    from eastern WY into southern MT. About 150 mi downstream,
    moist-deep convection is in the process of maturing over
    northeastern/eastern MT where higher buoyancy and an easterly
    low-level component persist. Much of this activity, strongly
    influenced by the approaching short wave, is producing large hail,
    especially over Richland/Wibaux County MT and northwestern Golden
    Valley County ND. Additional thunderstorm development will likely
    intensify across southeast MT as the Dakota outflow boundary
    propagates into a region of very steep lapse rates where surface
    temperatures are in the mid-upper 90s.
