    Concerning...Severe Thunderstorm Watch 412...
    
    Valid 140544Z - 140715Z
    
    The severe weather threat for Severe Thunderstorm Watch 412
    continues.
    
    SUMMARY...Sporadic strong to marginally severe storms may produce
    gusts of 45-60 mph and hail 0.75-1 inch diameter the next couple of
    hours. A new watch is not expected.
    
    DISCUSSION...A cluster of storms over central MO will continue to
    gradually develop south. Vertical shear remains rather weak with
    southward extent. Modest instability and steep midlevel lapse rates,
    in conjunction with a weak cold pool, may support sporadic strong
    storms another 1-2 hours before weakening occurs. 
    
    Another cluster of storms further north are occurring atop the cold
    pool from prior convection, but in a more favorably sheared
    environment. The storms will pose mainly a marginally severe hail
    risk for another 1-2 hours. 
    
    Given the marginal/sporadic nature of the threat, a new severe
    thunderstorm watch is not expected.
