This is a port of Finger in the Wind by Konlii for TerraFirmaCraft: The Next Generation (TFC:TNG) for Minecraft 1.12.2.
Overview (taken from the original mod post):
Every time I have to hit F3 to check the temperature, I feel like I am pulling a digital thermometer out of thin air.
So I made this mod to display the ambient temperature and rainlevel in a line of text at the top left-hand side of the screen.
The text is written without any numbers, so you might get something like:
"The air feels cold and dry" or "The air feels nice"
