I present to you the second script in a series called Realistic Temperatures – Upper USA, which will enable more diverse and realistic temperatures based on the location you are playing in FS25.
The Western USA, Central USA, and Eastern USA regions are covered (screenshot).
Installing the Central USA file and starting the game with the map is one way to start a game with a middle USA temperature. Remember that your predictions won't be entirely accurate if you don't have a weather monitor (as in the picture).
Additionally, depending on the locale, this mod allows rain, snow, and hail to occur in additional seasons.
Realistic weather must be implemented. The readme file contains installation instructions. I'm accepting suggestions for areas that I will visit after these current modules' beta period is over.
