    Areas affected...eastern Montana into western North Dakota

    Concerning...Severe Thunderstorm Watch 246...

    Valid 120123Z - 120300Z

    The severe weather threat for Severe Thunderstorm Watch 246
    continues.

    SUMMARY...A severe wind threat continues across eastern Montana and
    western North Dakota.

    DISCUSSION...A cluster of storms has developed across eastern
    Montana with echo tops over 40kft. Thus far, this cluster has moved
    through a data sparse region and no severe wind gusts have been
    reported. However, given the intensity of the convection and other
    storms in the region reporting severe wind gusts with less intense
    signatures, expect it may be currently producing severe wind gusts.
    As it moves north/east, expect the severe wind threat to continue,
    given the hot, well-mixed environment downstream. The eastern extent
    of this threat remains questionable as nocturnal cooling should
    weaken instability and thus the convection this evening. However,
    the HRRR suggests a strong enough cold pool may develop to maintain
    some severe threat through 05Z. If this occurs, the threat could
    eventually move east of watch 246. If this occurs a local extension
    may eventually be necessary. Trends will be monitored for this
    potential through the evening.
