Unreal Weather – Live METAR is a freeware mod simulating the real-world weather on the new Microsoft Flight Simulator, using up-to-date METeorological Aerodrome Reports, METARs. It provides a free alternative for the built-in “Live Weather” within the game. While the Unreal Weather – Live METAR mod uses only the current airport METAR reports to simulate the weather, the in-game default “Live Weather” utilizes the weather reporting at the airports with prediction services provided by MeteoBlue, plus some artificial intelligence on top of that.
The default “Live Weather” utilizes the internal weather simulation means in full capacity, while Unreal Weather – Live METAR mod is currently limited to the data model available on the Weather Settings menu. It, for example, cannot recreate different weather zones around the player, so the weather will always appear uniform. It supports smooth, user-configurable transitions between different weather states to provide the best experience though. This mod is a work in progress, which means that it is being constantly improved, often accommodating the feedback from its users.
The build-in Live Weather’s low altitude clouds at the airports are sometimes incorrect, but the Live METAR mod adds cloud layers correctly based on the latest METAR. Fortunately, you can change the weather source between Live Weather and Live METAR mod in-flight without pausing the sim. So for takeoff and landing as well as at low altitude, you can use the Live METAR mod source. While climbing to cruise altitude, you can switch to Live Weather for winds aloft from the custom toolbar Weather box and vice versa.
