With unseasonably warm and sunny weather the first three weeks, I thought that February might set a new production record for the month. Then the last week was all snow and clouds and the month ended up pretty average. It was weird to go from bare ground and temperatures in the 50s to twenty inches of snow in two days. The mountain snowpack went from 55% of average to 69%, so we are still well below normal here.
