Embracing the cold this winter, I did a painting of the Boulder Flatirons caked in snow.  Funny thing is that this photo I used for reference was take in MAY after a mid spring snowstorm a few years ago!
We also spent a weekend recently in Colorado Springs and I took a stab at doing a 1 hour plein air painting in the cold.  Wow!  That was revealing.  I now see how slowly I normally paint.  I definitely left wishing I had another hour or two.  Below is a comparison of a one hour painting of Pike Peak and a 20 hour painting of the same peak done years ago:
