I guess it depends on where you define the 'official' temp for Sac. WeatherSpark uses Sac Executive and I found 21 F on 12-24-1998. There used to be a temp reading that was listed as on top of the Post Office at 9th and I St, but it has disappeared from the NOAA page. I remember that location hitting the mid-20's 2004 or 2005. All of downtown and midtown shut down for a couple of hours because of black ice.
