    Attn: FlightSim.Com Store Customers

    As with all purchases from the FlightSim.Com Store you can download this product whenever you want in order to get the latest version. Just login to your store account and click on "My Account". There you will find download links for all your purchases.


    By utilizing inter-process communication with the simulator via fine granular control, you will experience automated, dynamic, and smooth weather transitions from real-world reporting metar stations.

    REX Weather Force - as real as it gets!

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


    • 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 comparison in REX Weather Force


    Weather Force reads remarks provided with live metar reports to determine if storms are near the aerodrome. Thus, even if the automated metar may indicate clear conditions, if remarks indicate storms nearby, storms will be generated near the reporting station as in real life.

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

    Dynamic Changing Weather Scenarios (DCWS)

    To add even more interest, Weather Force comes with dynamic changing weather scenarios (DCWS). These weather scenarios are dynamic, unlike the static default presets in Microsoft Flight Simulator. These Weather Force weather scenarios dynamically change over time and provide various elements of changing weather over the course of your flight. Examples provided below of included scenarios:

    • 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 can periodically add new and exciting scenarios, which will be automatically added to your application without the need to update Weather Force.

    Tracking The Weather

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

    The Goal

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

    Smoothing Mechanism

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

    Continued and Consistent Development

    The REX developers are dedicated to continuously develop and update Weather Force as new API¡¯s become available from Asobo and Microsoft, thus they have developed an implementary system to deliver program updates 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
