    (For the 18Z TAFS through 18Z Monday afternoon)
    Issued at 1027 AM MDT Sun May 19 2019
    Ceilings are lifting on schedule and gradual improvement should
    continue through the rest of the afternoon. Winds will increase
    from the east with gusts up to 20 knots possible at KDEN and KAPA
    20Z-00Z, but should shift more northerly 00Z-01Z, possibly a bit
    earlier depending on progression of surface convergence zone.
    Instability appears to be limited, so main threat of precipitation
    through tonight will be in the form of showers, with only a
    slight chance of a passing thunderstorm. Showers are not expected
    to produce much in the way of visibility obscuration due to the
    limited instability today.
    Lower MVFR/IFR ceilings are expected to redevelop after 06Z with
    still a few showers in the vicinity. Lower ceilings will likely
    hold around through all of Monday with moist north/northeast
    boundary layer flow and increasing showers and thunderstorms
    through the day.
