A free mod for Stardew Valley, by Alpha_Omegasis.
If you have played the game, then you know that there is no option to set a specific probability of rain, snow, or storms. You can only change the probability of each season, and the default values are very low.
And that is why I created this mod. Now you can set the probability of rain and storms for each season, and it will not only allow you to have more accurate weather forecast but will also provide a more realistic game experience.
How does it work?
The first thing you need to do is download the latest version of the SMAPI (Standard Mission API) from the Internet. After that, you will need to unzip the file into the game directory.
Now, you will need to edit the config.json file in a text editor.
