I think this game's weather are very cool. Its not make me bore while I'm playing this game everyday.
Could you make for more exciting and interesting weather like.
1. Thunder storm, player will have a very low chance get hit by Thunder strike and course that player to death or just a random damage.
2. Blizzard, sometime player will got Frostbite status.
3. Dust storm, player will get Blind effect or Bleed.
4. Umbral Static, player may got Shock effect or got hit by Thunder strike while he or she flying in the air.
5. Heat Waves, player will got Heavy effect because of heat.
In the other hand if the weathers are good like clear sky, player will get a random buff.

And a lot of effects from weathers according to real life.
