Well, at least you don't have to worry too much about ice. I opted to walk to work rather than try going down my big hill today.
My advice, pay attention to the flat spots and use them to brush off speed by braking gently when going through them.
Shift backwards as far as you can to keep your center of gravity between your wheels.
When braking hard, start gently, don't squeeze harder till you feel resistance. The feedback will tell you a lot.
Give yourself stopping distance, don't wait till the last moment.
When it's safe, go for it and enjoy.
