    Areas affected...eastern Montana

    Concerning...Severe Thunderstorm Watch 237...

    Valid 050210Z - 050415Z

    The severe weather threat for Severe Thunderstorm Watch 237
    continues.

    SUMMARY...The threat for sporadic severe gusts and marginal hail
    continues over parts of eastern Montana this evening.

    DISCUSSION...Several left-moving cells are currently moving
    east/northeast along the northern fringe of WW 237, and may produce
    marginal hail as well as strong wind gusts. The 00Z soundings from
    TFX and GGW show mainly unidirectional flow aloft, with up to 50 kt
    just below 500 mb. The GGW sounding in particular shows a good
    hodograph for splitting cells.=20

    Deep mixed layers are also noted due to warm surface temperatures,
    with little CIN currently. Therefore, while convection remains
    sparse across parts of the watch, additional activity may yet
    develop over the next 1-2 hours along various outflows, with both
    wind and marginal hail threat.
