For flight planning purposes, it'd be nice to have the future winds/temps available in order to plan for the most favorable altitudes along the route. As an example, the government site (http://www.aviationweather.gov/windtemp) has forecasts available for 6, 12, and 24 hrs. Perhaps the data to be displayed could be keyed off the "Departure Time" on the flight plan, which would eliminate the need for additional user-selected input fields to determine which timeframe to display.
