Turn off weather effects

There's heat and cold acclimation each for 500SP or heatproof and iceproof for 2000SP that your Sims can purchase under the reward traits.. at first, I was in doubt as well...but now, I am enjoying the seasons expansion pack..would recommend to buy..

And, by turning off the weather effects means you can switch off snow and blizzard, rain and thunderstorms..and an option to uncheck the effect of the weathers on your Sims...
