One more problem many of us from here have to encounter is that , we will be landing there from a very hot summer of 30 C avg temperature. So the affect of cold is going to be very significant.
I would suggest thinking about keeping your extremities warm, thinking from the top down:
+Head: a fleece (or wool) cap or balaclava, and possibly a "showercap" helmet or head cover to keep it dry up there (your hotel might have one you could take along).
+Neck: the balaclava (again), or a "buff"; you probably won't need one of the wicking neck coolers that those of us from cooler climates use in hot weather.
+Arms: the arm warmers, and/or a long-sleeve jersey
+Hands: nitrile or other plastic "exam gloves" can be a first layer and will cut wind on your skin (and also keep grease off in the event of on-the-road mechanical issues); then, long-fingered gloves and possibly overmitts. You want to get some insulation onto your fingers and hands and wrists, and keep it dry, without a) being too tight/restrictive (cutting off circulation) or b) too really thick and bulky. The air between gloves and overmitts is a bit of insulation. The exam gloves will trap sweat (if you have any), and over time make your fingers look like you have been soaking in the bathtub too long.
+Legs, Knees: Leg or knee warmers, or tights; "rain legs" (which mostly cover the front of the leg) are also effective at cutting wind exposure.
+Feet: See the other thread about booties / shoecovers. Note that the full covers also protect your ankles from wind; the toe-only covers not so much. Socks: be aware if too thick, might restrict toe circulation.
A piece of "Tyvek" - perhaps from a UPS/FedEx or similar mailing envelope - can be slipped between jersey and jacket for another measure of wind protection for your chest, somewhat like racers of old and the newspapers they used.
A "baselayer" tee-shirt (especially if wool) may help both with cold and hot.
Putting on new dry socks at a control, before sleeping, might help you get more rest. Then ride on, with those socks on.
