Help me to understand the phrase, "The models always sniff out the big ones early." Does this mean all the models spit out a lot of snow and keep it throughout all their cycles? Is there not wavering in the models even for the "Big ones"? If memory serves (which it might not as I have a poor memory) I believe even in the "Big ones" models will shift around a bit with snow amounts and then come into better focus within 2-3 days of the event.
