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

    Valid 071352Z - 071515Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Some increase in the severe threat is possible with time
    this morning.

    DISCUSSION...A loosely organized QLCS is currently moving across
    eastern IN, downstream of a mid/upper-level shortwave trough moving
    across the Upper Midwest. Despite strong low-level flow, this QLCS
    has generally remained subsevere thus far this morning, due to weak
    buoyancy and only modest large-scale ascent. However, relatively
    steep midlevel lapse rates were noted on the 12Z ILN sounding, and
    some increase in buoyancy is expected with time as continued heating
    and moistening occurs within the already warm boundary layer.=20

    With relatively gradual improvement of the downstream environment
    expected in the short term, potential for locally damaging wind and
    perhaps a brief tornado may remain rather isolated through mid
    morning, rendering the need for short-term watch issuance uncertain.
    A more substantial increase in the severe threat remains possible
    from late morning into the afternoon, as ongoing convection moves
    into an environment where greater pre-storm heating and
    destabilization is expected.
