1. A computer-implemented method of anticipating by a first computer results of a target weather model, the method comprising: (a) receiving, by the first computer, from a target weather model data source maintained by a second computer different than the first computer, one or more sets of first output data produced as a result of at least one previous run of the target weather model, and receiving, by the first computer, from an alternate weather model data source maintained by a third computer different than the first computer, at least one set of additional output data produced as a result of runs of at least one alternate weather model; (b) predicting, by the first computer, one or more sets of second output data expected to be produced as a result of a current run of the target weather model prior to the completion of the current run of the target weather model using the one or more sets of the first output data and the at least one set of additional output data, wherein the predicting occurs without the first computer performing runs of the target weather model and the at least one alternate weather model, and without observable weather data being used by the first computer in the predicting; and (c) providing a visual representation including the one or more sets of first and second output data corresponding to the at least one previous run of the target weather model and the current run of the target weather model, respectively.
