    (For the 12Z TAFS through 12Z Monday morning)
    Issued at 230 AM MST Sun Jan 3 2021
    
    VFR conditions expected at the terminals through the TAF period.
    Skies have remained clear overnight, but mid and high level clouds
    should return by the afternoon as mountain wave clouds develop.
    Winds so far tonight at have had a more westerly component
    overnight compared to typical drainage flow, and these winds will
    continue through roughly 21z before increasing and turning more
    west-northwesterly. Gusts up to 35kt are possible at BJC during
    the afternoon, with 20-25kt gusts likely at DEN/APA. Still some
    uncertainty whether or not stronger winds will be able to make it
    to DEN and APA during the later afternoon as the mountain wave
    strengthens, but for now will leave out any higher gusts. Drainage
    winds will return Sunday night through Monday morning.
