I believe that wasn't in lore or anywhere else, so a headcanon!
Dominance effects the weather conditions in Sornieth
For example, when Ice dominates, it becomes a lil bit cooler this week
When Fire dominates, it becomes hotter
When Light dominates, it's sunny
When Shadow - it's cloudy and dusky
When Water - it rains, rivers getting fuller (and it floods...)
When Lightning - there are thunderstorms everywhere (and sandstorms too)
When Arcane - there are meteorite showers
When Nature - everything BLOOMS and grows
When Wind - well... there are winds and hurricanes, obviously :D
Not sure about Plague and Earth, Earth could be either an earthquake times or a really calm, sort of "basic" good weather, and while Plague dominates, it's just easier to get sick. And it smells rotten flesh or something like this everywhere on the brim of your sense :'D (sorry for these crude stereotypes aahhh)
