Have to tried adding your map zone to the game_weather dbc?
Where which weather appears is server side. The DBC only defines how it looks.
As I don't know which server you use, or what you actually did: no I can't.
Please don't bump that fast. It has been less than 12 hours since your last post. Also, you have not answered the question of the first person trying to help you with hinting at game_weather.
It is not a dbc.
He told you to look at a specific table in the database. It is also the same table which comes up first when goggling "trinity core weather". Look at it..
