This site provides a view onto the FREE UK-specific RASP Weather Forecast model.

This model is designed to provide data and imagery for gliding but can be used by any one in the UK who wants to know their local weather in 30 minute segments.

It's a bit more involved than using the Met Office website (but not much), so interpretation is key.

  • Not in the UK? Looking for RASP forecast outside the UK? No problem - all the RASP models for the planet are here.

  • New to RASP? RASP introduction and interpretation videos can be found here.

  • Looking for a tailored service? There is a subscription-based forecasting service offered by or, which uses the same GFS source data but uses their own applications to provide a tailored service for a subscription fee. The RASP-based model here is free to use (see notes on re-purposing).
