Version 1.3 was updated to 1.4 by the auther a little while ago after yahoo! changed their weather format. It's in the Module Repository here:
https://xoops.org/modules/repository/singlefile.php?cid=85&lid=1743
It works fine for me on XOOPS 2.0.18.1 and PHP5 but others are having no joy with it.
To update, all I did was delete the module, upload the the new one and then update the module in Admin>Modules
