I would really be disappointed by the weather not being so ''realistic''.
One thing about The Sims 3 Seasons I loved, was the gradual subtile changing weather. For example when it was heavy raining, it also slowly stopped raining instead of just BAM! No rain anymore.
The subtile gradual changes were my favorite about that pack. Also trees slowly losing their leaves in Fall, slowly regaining their leaves in Spring.
And I hope they will manage to modify the backdrops in a way so that they slowly/gradually change with the Weather/Seasons.
Personally I never really liked the whole hot and cold meters. I don't know, it was always a limiting factor for me to take my Sims outside for too long, because of the risk being frozen to death or having a heat stroke.
I also do not really care about festivals. I'd rather have them spending more time at seasonal activities instead.
