    Areas affected...Portions of western North Dakota and eastern
    Montana

    Concerning...Severe Thunderstorm Watch 578...

    Valid 012305Z - 020030Z

    The severe weather threat for Severe Thunderstorm Watch 578
    continues.

    SUMMARY...A cluster of supercells with large hail and severe wind
    gusts will continue southeast this evening.

    DISCUSSION...A cluster of supercells has developed along and
    slightly ahead of a surface low and cold front across eastern
    Montana and western North Dakota. The strongest supercell, along the
    McKenzie and Mountrail county line, appears to be tracking along the
    cold front as it drifts south. The southward progression of this
    cold front, combined with an increasingly unstable airmass across
    southern North Dakota, should keep this activity ongoing well after
    sunset.=20

    Additional thunderstorms may develop over the next 1 to 2 hours
    south of the surface low across eastern Montana where high-based
    cumulus can be seen on visible satellite imagery. Very high dewpoint depressions in this region will support some strong downdrafts, but
    weak shear and limited instability should mitigate a more organized
    severe weather threat from any storms which develop in this region.
