By utilizing inter-process communication with the simulator viafine granular control, you will experience automated, dynamic, andsmooth weather transitions from real-world reporting metarstations.


Weather Force also includes a wide range of proprietary dynamic,changing (non-static) weather scenarios. These scenarios are unlikethe static weather presets that ship with Microsoft FlightSimulator.


  • The metar data is updated 6x an hour and downloaded directly from NOAA and can provide accurate results within a 1/8th mile of a given point.
  • Weather Force utilizes uniquely built algorithms to combine both metar and model data to cover sparse areas such as deserts and oceans.
  • The GFS (Global Forecast System) Model data is downloaded twice daily from NCEP and provides key atmospheric conditions to give a snapshot of temperature and winds aloft.



Weather Force reads remarks provided with live metar reports todetermine if storms are near the aerodrome. Thus, even if theautomated metar may indicate clear conditions, if remarks indicatestorms nearby, storms will be generated near the reporting station asin real life.



If you are looking to fly at a particular location or in certainweather conditions, Weather Force includes a handy weather searchfeature that allows you to search by airport or by weathercriteria.

Dynamic Changing Weather Scenarios (DCWS)

To add even more interest, Weather Force comes with dynamicchanging weather scenarios (DCWS). These weather scenarios aredynamic, unlike the static default presets in Microsoft FlightSimulator. These Weather Force weather scenarios dynamically changeover time and provide various elements of changing weather over thecourse of your flight. Examples provided below of includedscenarios:

  • Fair weather
  • Approaching cold front
  • Approaching warm front
  • Hot and humid summer
  • Lake effect snows
  • Winter storm
  • Crisp winter
  • Breezy
  • Spring showers



Because DCWS are centralized on the REX servers, REX canperiodically add new and exciting scenarios, which will beautomatically added to your application without the need to updateWeather Force.

Tracking The Weather

In Weather Force you have the ability to easily track your 10favorite airports, therefore, clearly identifying what the detailedweather is like at each. If you require a more detailed report, simplyclick on the ICAO and receive in-depth data about the airport weatherconditions.




The Goal

With Microsoft Flight Simulator, we have been provided a powerfulweather system as a start. The goal is to provide an even more robustweather environment. The REX developers have worked diligently torender the weather as it should be, yet stay true to the validity ofreal-world metar data.

Smoothing Mechanism

In addition, the REX developers have carefully added a smoothingmechanism to the engine to gradually smooth and transition the weatherover time between updates. Of course, you have complete control overthe weather update factors as well as transition speed.

Continued and Consistent Development

The REX developers are dedicated to continuously develop and updateWeather Force as new API¡¯s become available from Asobo and Microsoft,thus they have developed an implementary system to deliver programupdates quickly and easily to you.

The following is a list of updates coming soon after initial release:


Support for historic/archive weather data


Support for personal and community weather presets


Full featured flight center and mapping system
