Jacket for PNW

I ordered the insulated rain rebel coat but I think it won't be warm enough for here. It seems SO thin! Lulu's Parkas seem TOO warm and I dont think I want a puffer coat. I have the long puffer for when I am outside for long periods. I am looking for something to wear in the car, errands, to work, walks, can withstand rain, light snow, any suggestions?
