So, yesterday was sunny and 75F (~22C for you metric types). So to leave the house this morning, I put on a turtleneck under a t-shirt, two coats (hoodie under a warm jacket), and stuffed my hat and gloves into my backpack. At that point it was raining, but still not cold (~50F/10C), so my choices of apparel may shock the non-Pittsburgh people.
Now I'm regretting forgetting my scarf, for it's snowing. :)
