The Weather Research and Forecasting Model (WRF) is an advanced, community driven, and open source weather model that can be used for both operational forecasting and meteorological research at a variety of scales. Along with The NWU-Lekwena Radar, The NWU-WRF puts the North-West University Potchefstroom at the forefront of numerical weather prediction research in Africa, as the only university running an in-house, student driven operational weather radar and an operational numerical weather prediction model. Read more about WRF on the official user page.

Practical considerations and limitations
- The model is initialized using publicly available GFS data. The GFS forecasts are also viewable here
- The model requires spin-up time to become numerically stable, the first hour of the forecast should be discarded
- For observed Skew-T diagrams please visit the University of Wyoming Upper-Air Database
- Customized forecast products is available on request
- Please note that SAWS is the only entity in South-Africa which can issue weather related warnings
