Bright and sunny here!!

Clear blue sky ... birds singing ... temps up to the mid-20s during the day.
But when winter comes, I try to get out in the sun whenever possible even if that is just a half-hour walk at lunch time. You might also try joining a spinning class, going to the local pool, and of course, getting out for rides on the weekend no matter what the weather.
In Canada, I found that 10 minutes of the tanning beds once or twice a week for a few weeks also helped.
