Snow showers and sub-zero temperatures could combine for slippery road conditions in Madison and southern Wisconsin Tuesday night into early Wednesday.

The National Weather Service said a 1-3 hour burst of snow showers could produce a half-inch of snow between 9 p.m. and 3 a.m., making for slick pavement in the frigid overnight hours.

No wind chill advisory has been issued for Tuesday night because winds won't be blowing like they've been the past two nights, but there are chances for advisories Wednesday and Thursday nights.

Wind chill advisories are issued when the wind chill values are expected to drop to 20 below or worse.

The day-to-day outlook:

  • Tuesday night: 70 percent chance of snow showers, low around 4. Up to a half-inch of snow is possible.
  • Wednesday: Mostly sunny, high near 11.
