I like this plugin, although it could have some enhancements to make it much better, it uses the open public API "http://api.wunderground.com/auto/wui/geo/ForecastXML/index.xml" which unfortunately will be deprecated as per wunderground.com, now it is intermittent, so you would expect that it might work or not work at any time, luckily without any messages on pages that used on.
This comes up with the question to the developers, where are we with the new API that have been there for a while, should we wait untill the old one stops completely, it seems very soon.
Now we need an upgrade that uses anyones personal API key which can be generated after registration at wunderground.com.
We do appreciate your work and your effort, but we need this update urgently.
Best regards to all,
