In Australia, every month economists predict the expected unemployment mainly by extending the smoothed trend line, and then there are a lot of articles making claims about the reasons for the deviation from the expected, which is only statistical noise. The Australian Bureau of Statistics even plots the trend and seasonally adjusted together for the previous 12 months so that the noise is clearly visible.
