I should have added this before, but I didn't. You always want the clothes required to move through bad weather. So many rescues in the Sierras are of hypothermic people who assumed that they would not need warm dry clothes. Have the warm clothes to get up and hike in what you think will be the worst weather. Err on the side of warm hiking clothes.
