Don't worry about it. This can be a casual side thing (unless you're really interested in this xP).

Perfect. I'll read it now. :)

EDIT: I don't think the temperature should have gone to "freezing"...I would expect just a normal temperature. 
However, that would interfere with the snow sticking to the sand. 
I just feel like Sunny Day's purpose to be hot and sunny to boost Fire, Solar Beam, and possibly stuff like Leech Seed, Ingrain, and other such attacks. Now it seems like Sunny Day is only allowing Sunlight to boost Grass but not keeping the heat, which is lessening the effects of Hail to make it not painful but still able to benefit Ice. I mean, that's fine since I'm not using a Fire type, but I'm not sure if it's really balanced.
What do you think?
