    Mesoscale Discussion 1724
    NWS Storm Prediction Center Norman OK

    Areas affected...Northeast Nevada...southwest Idaho

    Concerning...Severe potential...Watch unlikely=20

    Valid 101902Z - 102100Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A few strong to severe wind gusts will become more likely
    through the the afternoon. Limited coverage of these wind gusts
    should preclude watch issuance.

    DISCUSSION...Strong surface heating has steepened low-level lapse
    rates across central/northeastern Nevada. Buoyancy remains quite
    limited given the marginal surface moisture. Even so, isolated
    storms have developed over the last 30-45 minutes. This activity as
    well as new storms should continue to develop and deepen into the
    afternoon as the surface continues to warm and subtle mid-level
    cooling occurs. Modest flow thorough the lowest 4 km will combine
    with strong evaporatively driven downdraft accelerations to produce
    a few strong to marginally severe wind gusts. Though storm coverage
    may approached scattered criteria, minimal buoyancy will keep the
    severe threat isolated. No watch is anticipated.
