When any car idles, it lowers the ignition energy (but not completely) to keep the car running. When it is cold outside, your Subaru's ignition energy is lost through heat because electricity also is measured through heat. When there is less ignition energy when it is already running on a lower ignition level, the car (your Subaru) is not likely to idle.
