Hi: I'm from MN but ride in FL during Jan and Feb. I've found that Pearl Ozumi sells a pair of gloves that works well for me down to those temps of yours. I bought them last season and I think they cost about 70 bucks. I know that's spendy but if you are going to ride in cold weather on a regular basis, you have to spend the money and get the good gear or its no fun at all to be riding in.
good hunting!!
