as the saying goes, wait five minutes and the weather will change.

During the competition you will be inside and it will get warm in there most likely. But a sweatshirt with a t-shirt underneath should be fine, with maybe a light jacket. You can always take off layers, but you never know what the weather will be. As long as you have what is suggest above you should be fine, for outdoors (but that is the minnesotan in me).
