    (For the 18Z TAFS through 18Z Tuesday afternoon)
    Issued at 206 PM MDT Mon Apr 23 2018
    
    Showers are beginning to push off the foothills this afternoon
    which should result in winds turning more back to the west and
    north west. Main frontal boundary still expected around 03z at
    KDEN as winds shift and increase northerly. Shallow upslope flow
    will develop behind the front and could lead to a persistent
    pattern of showers after midnight. Temperatures appear to be cold
    enough for a mix of rain/snow towards midnight and finally all
    snow before daybreak. However, by 11-12z time frame, airmass aloft
    begins to dry out over Denver and also near the surface. If
    moisture remains saturated in lowest levels, then possible
    freezing drizzle could develop but confidence in that scenario is
    quite low and will not mention.
