Below are Graphical Data Forecasts centred on Talgarth Airfield showing Thermal Strength, Thermal Height, Cloudbase, etc. for 7 days. These are followed by other graphical data including Windspeed (Upper and Surface) and Wind Direction. The graphs show the day from 0700-1800, so you can see how thermal strength, cloudbase, etc. varies throughout the day.
Below each Graphical Data Forecast is a RASP generated cross country soaring "Star Rating" for the same day (0=Poor, 5=Excellent).
