SkewT Aero helps pilots truly understand the atmosphere and what that means for a planned flight. Explore weather along your route using interactive visualizations built directly from modern forecast guidance. Compare departure times, inspect hazards, and understand how clouds, winds, icing, turbulence, convection, ceilings, and visibility evolve before you fly. Every view is synchronized by route, time, and altitude. Move anywhere along your route or compare different departure times to see how the forecast changes throughout the flight. SkewT Aero complements tools like ForeFlight and Garmin Pilot by helping pilots explore forecast guidance in greater detail before making weather decisions. Features include interactive route weather visualization, route hazard timelines, vertical atmospheric profiles, forecast soundings (Skew-T), route stations, nationwide weather maps, operational NOAA forecast guidance, offline weather and navigation data, and hourly forecast updates. Forecasts are built from operational NOAA guidance including HRRR, RRFS, GFS, NBM, DAFS, and LAMP. Rather than reducing those models to a text briefing, SkewT Aero lets you interact directly with the atmosphere they predict. Whether you're evaluating today's flight or planning several days ahead, every view stays synchronized so you can quickly understand how weather changes with location, time, and altitude.
