    Areas affected...Northern/Central MO

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

    Valid 110949Z - 111115Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A few strong storms are possible but the overall risk for
    any severe thunderstorms appears low.

    DISCUSSION...Elevated thunderstorms have begun to develop within the
    warm sector ahead of a low-amplitude shortwave trough moving across
    eastern NE. Recent water vapor imagery shows the ascent attendant
    to this system well (in the form of cooling cloud tops across northern/central). Steep mid-level lapse rates are in place,
    contributing to moderate buoyancy. In contrast, vertical shear is
    relatively modest, particularly in the layer where the buoyancy
    resides (roughly above 700 mb). As such, updraft longevity will
    likely be tempered, which should also limit any hail potential.
