Weather on the map - seems to be everything at once

I noticed many funny weather effects on the map (Krystara and Underworld both): snowing, aurora borealis, sand winds, swamp mists, mountain clouds, lava sparks and smokes… but they seem to happen all at once: about an hour after a new day was started. The rest of the day is calm, only water glitters always. Maybe it must be not so “dense”? One hour - clouds, another hour - sparks, then snowing… Just an idea.

Sounds interesting! Day/night effect as we?
