"Overall, I am pleased with Weather Force and strongly recommend it for anyone trying to add realism. Fantastic job REX!"

With Realtime Metar Data as the Foundation, Our Weather Engine Provides a More Realistic Weather Experience.

  • 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.

REMARKABLY UNIQUE

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.

POWERFUL WEATHER SEARCH

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

Includes Dynamic Weather Presets!

Don't settle for static presets.

To add even more interest, Weather Force comes with dynamic weather presets. These presets are dynamic and change over time, providing various elements of changing weather over the course of your flight.

Examples of included presets:

Fair weather
Approaching cold front
Approaching warm front
Hot and humid summer
Lake effect snows
Winter storm
Crisp winter
Breezy
Spring showers
Blizzard
Thunderstorm
Rainy Day
Bob Ross Happy Clouds

REX periodically adds new and exciting presets, which are automatically added to your application without the need to update Weather Force.
Dynamic Weather Presets from REX in Microsoft Flight Simulator

The Goal

With Microsoft Flight Simulator, we have been provided a powerful weather system as a start. The goal is to provide a more robust weather environment. We 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, we 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.
