Fuck. Just read I need to register or whatever.

Now I'm getting: Location found. No data provided. (Replacing 'location' with whatever location was used in search)

Go down to line 593 and comment out the unset. Run the command. Then look at your variables. Your results should look like this:

Try a more common location and see if it still does the same. Your location may not be available.

Some locations work, others don't. But there are places that are so large they should have data (ie, some major cities have 'No data' and some VERY small towns do).

Can you specify what towns you are mentioning? I might be able to look at them and see if there is something else that may be a fault.

[18:00] <@Me> !weather yorkshire
[18:00] Yorkshire Found. No data provided.

@cptpan This is because you are not specifying the State. If you look at the xml page: http://www.wunderground.com/cgi-bin/findweather/hdfForecast?query=yorkshire You will see that there are two locations listed. Same if you searched it directly on wunderground ( http://www.wunderground.com/cgi-bin/findweather/hdfForecast?query=yorkshire ) It is asking for which location. NY or OH. But let me see what I can do about adding this option as a feature.

Update: New v5.4 code posted. It will now notify you if your request has multiple results.

[11:19] !weather wollongong new south wales australia
[11:19] Wollongong Found. No data provided.

The weird thing is it returns weather for nearby locations that are MUCH smaller than Wollongong.
