I am from Seattle and going to Scottsdale Dec 1st thru Mar 31st and need to know what kind of clothing to take. I have lots of winter clothes from living in Seattle and know the average high of 68 and low of 43 for Scottsdale, but don't understand which of my fall and winter type clothes to take. Would light weight wool pants and light sweaters be best, or more cotton pants, and cooler silk tops be preferable. I will be working from my condo and going out some to dinner, etc., mostly casual stuff. I am a writer and artist and am 63 years old.
