As has already been mentioned, 30 degrees F is not particularly cold.
At any rate, it's not a good idea to wear cotton clothes since they will get wet from perspiration. Standing on a mat, rug, or carpet remnant will help to keep your feet warm. Of course, good boots and thermal socks are a must. If you don't want to go to the expense of a snowmobile suit, get a pair of insulated coveralls.
I usually wear insulated boots, a high quality thermal underwear top and bottom, thermal bootsocks with liners, a sweater or insulated flannel shirt or sweatshirt, a hooded sweatshirt, flannel or fleece-lined pants, sweatpants over the pants, an insulated coverall, and a down coat with a hood. I have at least two hoods covering my head and sometimes wear a combination facemask/hat as well. I use a variety of gloves and mittens depending on how cold it is and also rely on heat packs when necessary. With this gear on, I'm good for many hours of winter observing.
