    Areas affected...portions of central Kentucky
    
    Concerning...Heavy snow 
    
    Valid 282244Z - 290145Z
    
    SUMMARY...Brief instances of heavy snow and reduced visibility may
    accompany a band of snow showers moving southeast across central
    Kentucky. Brief instances of 1 inch/hour snowfall rates with
    quarter-mile visibility are the greatest concern.
    
    DISCUSSION...A relatively organized band of moderate to heavy snow
    has recently developed across northern Kentucky, with heavy snow and
    reduced visibility recently observed at KSDF. These snow showers
    will persist southeast amid a conditionally unstable low-level
    environment, where 22Z mesoanalysis depicts 0-3 km lapse rates
    exceeding 7.5 C/km in spots. For the next couple of hours, these
    low-topped snow bands will continue to benefit from the steep lapse
    rates, promoting strong wind gusts and heavy snow. Up to 1 inch/hr
    rates are possible in the core of the snow bands, where reduced
    visibility down to a quarter mile may occur. As low-level lapse
    rates weaken after 01-03Z, the heavier snow threat is expected to
    gradually diminish.
