Methods and systems are provided for presenting forecast information pertaining to a planned route of travel, such as a flight plan. One exemplary method involves obtaining a plurality of forecast data sets associated with a plurality of different forecast time periods and subdividing a route into a plurality of forecast regions encompassing respective portions of the route based on the times associated with the navigational reference points defining the route. Each forecast region of the plurality of forecast regions is associated with a respective forecast time period. For each forecast region, a graphical representation of a subset of the forecast data set associated with that forecast region's associated forecast time period that corresponds to the geographic area of that forecast region is displayed on a display device concurrently to displaying a graphical representation of the route.
