This plugin allows you to specify real-world GPS coordinates for each in-game world. It will then periodically look up the current weather conditions (rain, thunder, snow, etc.) in the real-world location and change the weather of the in-game world to match.

Use cases:

• For a more immersive experience when playing on a server with local friends, set the location to your actual location and the weather in the game will match whatever is happening outside.
• Mapmakers can choose particularly rainy or dry locations to give more authenticity to the weather patterns in their worlds.

For help configuring the plugin, refer to the wiki.

This plugin is fresh out of development and I'm currently testing it on my own server. Feel free to create issues for bugs you find and/or reasonable feature requests.
