The weather radar can be found here, and it does exactly what it says on the tin, providing a likely model of weather system movements for the next seven hours, and projections further forwards in three hour chunks.
There’s a host of other useful data available, which you can access using the ‘map menu’ buttons to the right of the page. Datasets there include temperature, pressure, cloud cover and wind.
You can zoom in and out and pan the map around using the arrows and slider to the top left of the panel. Click here to take a look.
