The SREF continues to climb this afternoon with the ensemble forecast for snowfall. This morning we were sitting at an average of 11.83 inches of accumulation between all models.

This afternoon we are at 14.07 inches as a mean. I think this may be a bit overdone based on temperatures but does give me higher confidence in the 8-12 inch range for Castle Rock.

Stay tuned!
