Sea Level Pressure - Plotted using isobars displaying the pressure levels in contours
Accumulated Rainfall - Displays sea level pressure and the accumulated rainfall amounts since the model start
2m Temperature - The forecast temperature in centigrade at 2m above ground
Freezing level - This is also known as the zero degree isotherm and shows the height at which all air above is freezing or below
Overview - This shows you whether precipitation will fall as sleet, snow, freezing rain or ice pellets. Also shown is cloud cover and Isotherms :-
Dark blue – 510dm (Snow at sea level)
Blue – 528dm (Snow on mountains/hills)
