This late December and early January have been nice so far, but October and the first 3 weeks of November were much more wet than usual. There were at least 4 weeks in those months that 8/10 commutes were under rain, and the other weeks weren't far behind. And September was also rather humid. We typically have only 1 or 2 weeks of rain – total – in the Fall.
So I'd rather get -10 – -15°C and snow.
