The description of the variables shown above are as follows :-
Temp (2 metre Average Temperature) - This is the average temperature forecast at 2m above ground
Dew (2 metre Dew Point Temperature) - This is the dew point or wet bulb temperature of the air in the 1 or 3hr period
Speed (2 metre Wind Speed) - This is the average wind speed recorded at 2m above ground
Rain% (Rain Probability) - This is the forecast probability of rain. If rain is forecast then it will show you the percentage confidence in this. If no rain is forecast but the RainRisk is above 0 then it means that the deterministic forecast is not expecting rain, but ensembles are still showing a risk.

Speed (2 metre Wind Speed) - This is the average wind speed recorded at 2m above ground
Gust (Surface Gust Wind Speed) - This is the average gust wind speed expected within the forecast period.
RH (2 metre Humidity) - This is the forecast relative humidity of the air at 2m above the ground
UV (UV Index) - This is the UV Index from 0 to 10 based on the cloud cover and strength of sunshine
