Hi,
Don't know if you've all spotted the new Met Office "Invent" weather forecast page.
"This area showcases new forecasts and products under development".http://www.metoffice.gov.uk/public/pws/invent/weathermap/I find it pretty impressive.
It now shows forecast precipitation - which can be quite useful at present!
Another website I use for weather has had the preciptation forecast maps for some time,
and you can even put a marker on the map at your own location
