I'll be hiking the Maine A.T. starting July 8. I want to keep my pack weight to a minimum. Will I need a jacket?

I will have several layers of shirts, including a base layer and long-sleeved cotton flannel shirt. I'll also have a poncho in case of rain. But I'm debating whether or not to bring a Columbia rain jacket along for added warmth.

Thanks.
