This takes a little practice but I find the ebrake very handy in the winter. I'll explain for those not familiar. Let's say you go into a turn and the front end starts to push through the turn, if you pull on the ebrake (thumb on the lock button) just long enough to get the wheels to lock for a second. You'll know if you applied to much if you do a 180.

The back end will slide a bit and the front wheels will find their traction 9 out of 10 times depending on the conditions.
A good all season tire IMO are Goodyear Aqua tread 3's. Very good dry road manners, excellent wet handling and very good in the snow. Plus there speed rated and have a 60000 mile warranty.
I think in Colo. you can have tire chains. It's a good idea to pickup a set just in case because you will see 2 foot snowfalls regularly.
