Hello, any fabbers out in Chicago? What's the weather/wind conditions like for the next couple weeks? I'll be out there for business & fun some time the next 10 days or so.

Weather forecast states 30-50, with some days rain/snow. Are there ice/slush on the ground? Besides a wool peacoat i don't really have anything warmer. Will I survive? (me in 70+ degree weather right now). Windchill factor probably make it feels much colder? What about shoes? I have a few pairs of booties but I'm trying to limit my luggage. I may have to walk a little bit from hotel to my business meeting, so I'm opting for an almost flat leather ankle boots (better than my heeled but more dressy bootie for walking).

As for indoors, i presume there is heater, thus a layered shirt, with either a light jacket/cardigan should suffice? Any suggestions? Sorry for the rambling and thanks in advance!
