Saw this on the six o'clock news tonight (Monday). On the Metservice.com site, click on your home town, and then on the Your Weather tab to the left of the 5 Day and 10 day tabs. The idea is that if you have a weather station you can share your data with other people. You have to register and account with the UK Met Service WOW (Weather Observation Website), and if you have a weather station with a wireless connection to an app like Cumulus, you'll have real time updating info for your site.
These are the Auckland site locations

I have an Aercus WS3083 and Cumulus, and have registered a WOW account, but not yet completely sussed getting online. It's a bit of a palaver, so I'm hoping other people might be interested. There are also the Cumulus forums where people are bound to know the ins and out of it all.
