Ok we call that a nice riding day here

Under Armour and PolarTEC undergarments will work real well for you they help keep heat in but do not over heat you .
I like the Polartec tops because of the thumb hole in the end of the sleeve they do not ride up the arm on you.
A mid-weight set of gauntlet gloves to heavy and your hands will hurt from over size grip and they get to warm in that weather cost 50-how much you got.
A vest, leather jacket and chaps your good to ride.
If you do not have hard lowers a set of soft-lowers are are amazing about 50-60 bucks for the good HD ones. great once it drops below 50 degrees.
Fleece face cover for face and under helmet 9-20 bucks depend were you buy it and who's designer name is one it.
Good boots with Gortex help with some fleece or thermal type socks 10-20 bucks same reason as above.
cheap set of boot condoms meant for the rain but work real nice in cold.
12-50 bucks.
