    For the 06Z TAFs...
    
    Primary forecast remains the potential for snow showers/flurries
    early Thursday afternoon.
    
    A cold front will move across the area early Thursday afternoon
    and there remains a chance of snow showers or very light snow
    during this time period. Confidence remains low and opted to keep
    prob mention going with this forecast. If snow does materialize...
    there is the potential for brief ifr vis and perhaps a dusting of
    snow accumulation but likely not in all areas.
    
    Mvfr cigs are expected to shift east of the Chicago area terminals
    in the next 1-2 hours with a period of mainly clear skies
    overnight with more mvfr cigs spreading across the area Thursday
    morning. These mvfr cigs may persist longer than expected...well
    into Thursday evening...with uncertainty regarding when these cigs
    will scatter out.
    
    West/northwest winds around 10kt will become more westerly by
    morning. Wind speeds/gusts will increase behind the cold front
    with gusts into the mid 20kt range. By late afternoon/or early
    evening...forecast soundings suggest there could be a several hour
    period of winds gusting toward 30kt...which then slowly diminish
    later Thursday night into early Friday morning. cms
