Last season didn't produce as much snow as a typical La Nina year in the mid-western part of the US. Prolonged dry spells off set warmer than normal temperatures to make for a less than desirable winter for skiers.
Typically, La Nina winters produce a fleet of lake effect snowstorms and bring Arctic temperatures to much of the Midwest. This year shouldn't be any different. With the Pacific jet stream hanging around the north, cool Canadian air should make temperatures ripe for snowmaking and plenty of snowfall, especially in northern Michigan and parts northeastern Wisconsin. Some warm pacific air might make an cameo appearance, but not for an extended period of time. For the most part, ski areas around the Great Lakes should have a pretty good year.
