Well, I remember last year when for 2 or 3 weeks in late January into mid February, all 3 global ensemble models had our region consistently near 10 inches or more of snow.
Ground truth turned out to be a light event or two. Point is, I no longer get excited about the 15 day ensemble totals until there is a specific threat to track. They should mainly be used for pattern recognition & identifying windows of opportunity in my opinion.
