Set chart mode to local horizon. Set the field to 45°, azimuth to 180°, and altitude to 55°. Turn on Jupiter. Set the date to today's date and the time to midnight. Set the time step to 2 days and start the animation. When Jupiter is near the center of the field (that is, almost on the meridian), step back and forth until you find the date when Jupiter is on the meridian closest to midnight. Calculate how long you will have to wait to observe Jupiter high in the night sky at midnight.
