Forecasting Methods There are several different methods that can be used to create a forecast. The method a forecaster chooses depends upon the experience of the forecaster, the amount of information available to the forecaster, the level of difficulty that the forecast situation presents and the degree of accuracy or confidence needed in the forecast. The first of these methods is the persistence method : the simplest of producing a forecast. The persistence method assumes that the conditions at the time of the forecast will not change. For example, if it is sunny and 37 degrees today, the persistence method predicts that it will be sunny and 37 degrees tomorrow. If two inches of rainfall today, the persistence method would predict two inches of rain for tomorrow.
