one thing i realized on the PCT in all the rain is that you probably won't be warm and DRY while hiking up hills in the rain, but you'll want to be at least warm and DAMP. you don't want to be COLD and damp. most rain jackets have a hard time keeping up with the perspiration created by hard work hiking carrying a pack in wet weather. i used a marginal Marmot Precip jacket in 2004, and it definitely was a warm and wet situation.
key to this for me was having a dry sleeping bag and dry sleeping clothes (thin long johns and socks) to get into when the day was over, inside a dry-ish shelter.
hopefully you'll miss most of the rainy/colder weather with your earlier-ending schedule.
