    Areas affected...north-central and northeast Nevada...northwest
    Utah...far southeast Oregon...and southern Idaho.

    Concerning...Severe potential...Watch unlikely

    Valid 212035Z - 212300Z

    Probability of Watch Issuance...5 percent

    SUMMARY...The threat for a few severe wind gusts up to 70-80 mph is
    expected to increase by mid to late afternoon. A watch is not
    expected due to the isolated nature of the threat.

    DISCUSSION...Subtle mid-level disturbances embedded in a moist,
    southerly flow regime are contributing to a gradual increase in
    thunderstorms this afternoon across portions of central and southern
    NV. Modification of the 18Z LKN sounding for hotter surface
    conditions currently observed over northeast NV into northwest UT
    yields MUCAPE of 500-750 J/kg atop a 3-4 km deep, well-mixed
    boundary layer. As such, thunderstorms are expected to move/develop
    north through the region this afternoon into evening with an
    associated risk for locally severe wind gusts up to 70-80 mph,
    driven by strong evaporational cooling potential in the sub-cloud
    layer. Explicit wind gust fields from the latest CAM data continue
    to highlight portions of north-central and northeast NV into
    southwest ID as a most likely corridor for the strongest gusts to
    occur.
