Cheating at Weather Forecasting

Why not follow the Bureau of Meteorology's recent trend of forecasting Perth temperatures badly (2 or 3 degrees out) and then revising the forecast retrospectively once the day's maximum is reached. For example, we hit today's forecast of 39 degrees by 11.30am, and so they've upped the forecast to 41 degrees. What a great idea ! All forecasts should be revised in light of reality. Then we'll live in a world of 100% accurate forecasting, the only problem being that the final forecast is not available until after the event.
