1. A method of providing information related to a weather phenomenon, the method comprising: (a) obtaining a plurality of model tracks corresponding to the weather phenomenon for a current forecast period from two or more forecast centers; (b) assigning a scaling factor to each of the plurality of model tracks based on which of the two or more forecast centers produced the respective model track; (c) determining, by at least one computer, a probabilistic description of one or more characteristics of the weather phenomenon based on a statistical analysis of the model tracks corresponding to the weather phenomenon using the scaling factor assigned to each of respective model tracks; and (d) providing an electronic representation of the probabilistic description.
