I created a new block, this time for users in Australia. First you select the territory you want to use and your default city.
The block then shows you long-term forecast for all the cites in that territory. The data is updated every 6 hours, it might take sligthly longer the first time you load this before it loads all the data and caches it, then it loads instantly.
The block works nicely in both wide and narrow configuration.
