    Areas affected...Southeast Wyoming into Nebraska Panhandle

    Concerning...Severe potential...Watch possible=20

    Valid 302005Z - 302200Z

    Probability of Watch Issuance...60 percent

    SUMMARY...High-based storms moving out of southeast Wyoming will
    eventually encounter greater moisture in Nebraska. Storms will be
    capable of strong/severe wind gusts and large hail. Hail in excess
    of 2 inches is possible as storms intensify in Nebraska. A watch is
    possible this afternoon.

    DISCUSSION...Thunderstorms are beginning to form within the Laramie
    Range and a modest surface trough in the High Plains. These storms
    will be relatively high based given the low 50s F dewpoints in the
    immediate vicinity of the terrain. Greater moisture resides to the
    east. So far this afternoon, dewpoints in the Nebraska Panhandle
    have mixed down to the low 60s F as the surface winds have veered.
    Farther east, southeasterly winds have been maintained with
    dewpoints remaining in the low 70s F into central Nebraska. Early
    storms will be capable of strong/severe wind gusts and perhaps some
    marginally severe hail. Very large hail would be possible as storms
    interact with richer low-level moisture, though this is conditional
    on a discrete storm mode being maintained. Most guidance shows at
    least a loosely organized cluster of storms moving east into central
    Nebraska which could pose a greater threat for severe wind gusts. A
    watch is possible later this afternoon.
