Tim, it’s much milder here. While we can get snow it usually disappears in a couple of days. The typical December daytime temperature would be from 5-12C so there is usually no problem to treat on a mild day.
In past years I have used the dribble method (5ml between each frame of bees), but this year I will be using a gasvap.
And yes, bees will be flying here on mild calm days in December, mostly cleansing flights but sometimes they will even bring in pollen. We get a lot of rain which is tougher on the bees than cold. Mild winters can result in stores being used up causing starvation in early spring if we are not careful.
