What If Seasons is Confined to Specific Locations?

I feel we need more then Just seasons, we also need extreme weather, like hailstorms, snowstorms thunder/lighting, and tornados, also severe weather alerts.
What do our saves have to do with whether or not it's raining outside.? Even our Pets know inside the house from outside the house, and we know who gave them that knowledge.
So what area of a save might be affected by, oh it's snowing now the Sims don't know where they live anymore? :| I don't think so.
