The three outcome maps give the tercile rankings of the rainfall totals, mean air temperatures, and mean river flows that eventuated from August to October, in comparison with the forecast conditions.

As an approximate guide, middle tercile rainfalls typically range from 80 to 115% of the historical normal, and middle tercile temperatures range about the average by plus or minus 0.5 °C.
