Rain and Thunder:

Thunderstorms tend to make Sims very tense... Watch out for that lightning. Sims caught in a storm for too long risk injury or even a visit from the Grim Reaper. - blog post

From the livestream*:

• There are no power outages, but they said that during thunderstorms electronics might break
  

Hot weather:

Make sure to change Sims into their summer outfits or they’ll risk overheating. And, what better way to cool down than take a dip in the pool? Last one in is a . . . painfully uncomfortable Sim. - blog post

As you may expect, the not-so-fun parts of winter blow in, too. For one thing, it's freeeezing! And without the proper outfit, your Sims will shiver and shake in their boots. Make sure to bundle up before heading outdoors for longer periods of time. If you don't, your Sims will be so blue. Literally. The colder they get, the higher the risk of - you guessed it - death. - blog

The Weather Inside

And while we’re on the subject of weather conditions, we should probably tell you about the thermostat, which will regulate temperatures inside your Sims’ homes. When we say regulate, that could really mean anything to you. Make a cheating boyfriend sweat it out, make a family want to huddle together to survive the cold. Ah, so many trolling possibilities. It’s hard to choose just one. - blog post

Laundry:
From the Livestream*:

• If a hamper (Laundry Day) is placed outside when it's raining, the clothes will get wet. Also, if a sim gets wet because of the rain, when they switch outfits the generated laundry pile will be wet as well. Clothes hanging in the clothesline will not dry either (although this last part was already known)
