    Mesoscale Discussion 0094
    NWS Storm Prediction Center Norman OK
    0444 PM CST Fri Jan 28 2022
    
    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.

    Day 1 Convective Outlook  
    NWS Storm Prediction Center Norman OK
    0217 PM CST Fri Jan 28 2022
    
    Valid 282000Z - 291200Z
    
    ...NO THUNDERSTORM AREAS FORECAST...
    
    ...SUMMARY...
    The risk for thunderstorms appears negligible across the U.S.
    through tonight.
    
    A few thunderstorms have occurred over the Gulf Stream, well
    offshore of the East Coast. The threat should remain offshore
    through the period.

    .PREV DISCUSSION... /ISSUED 1001 AM CST Fri Jan 28 2022/
    
    A deep upper trough will amplify and become negatively tilted
    tonight over the eastern states, resulting in rapid cyclogenesis off
    the Atlantic coast.  While thunderstorms will be possible offshore
    tonight, organized deep convection is not anticipated over land
    areas.

    ..Lyons.. 01/28/2022
    
    .PREV DISCUSSION... /ISSUED 0201 AM CST Fri Jan 28 2022/
    
    ...Synopsis...
    Broad northwesterly mid-level flow will prevail across the Plains
    states as an upper ridge across the Interior West slowly approaches
    the Rockies tomorrow/Saturday. An embedded mid-level impulse will
    traverse the Central Plains tomorrow, with surface lee-troughing
    across the Plains states ushering in dry surface air from the High
    Plains. By afternoon peak heating, widespread 15-20 percent RH is
    expected to overspread much of the central and southern Plains.
    Portions of central Nebraska will be overspread by stronger flow
    aloft given the passage of the embedded mid-level impulse,
    encouraging relatively widespread 15+ mph sustained westerly winds
    coinciding with the lower RH. When also considering the dry fuels
    across the central Plains, Elevated highlights have been introduced
    for portions of central Nebraska into extreme northern Kansas.
    
    Weaker upper support across the southern Plains should keep surface
    winds below 15 mph on a widespread basis from southeast Colorado
    into western Texas eastward to central Oklahoma. However, the 15-20
    percent RH by afternoon peak heating overspreading dry fuels may
    support at least localized fire-spread concerns. Should guidance
    depict more widespread stronger winds across the southern Plains,
    Elevated highlights may be introduced.
    
    Lastly, 15 mph sustained northwesterly surface winds overlapping
    25-35 percent RH may accompany a post-cold frontal environment
    across the Florida Peninsula tomorrow afternoon. While such
    conditions would typically warrant Elevated highlights, relatively
    high fuel moisture/low forecast ERCs suggest that fuel receptiveness
    is mediocre, precluding fire weather highlights this outlook.
