Summer Forecast 2022: Sizzling Summer Ahead - Farmers' Almanac - Plan We see an increased snow potential over the upper Midwest, with some other areas across the Midwest having normal snowfall amounts forecast this month (0/white areas). To determine this signal, I first calculated the average of the December-January Southwest U.S. precipitation across all 30 ensemble members for each La Nia. From my experience, the superposition of the ENSO and MJO teleconnections can be treated as linearly additive, so the MJO influence (like what's shown here) can constructively or destructively interfere with the expected ENSO influence. The rest of the United States shows less snowfall than normal, but that does not mean no snow at all. We see an equal-to-higher probability for more precipitation (and snowfall) over the northwest, extending into the Great Lakes and the eastern United States. That can be interpreted as a potential route of winter cold air outbreaks down from the Midwest to the south, creating occasional snow events. Annual snowfall in the Twin Cities based on the modern 30-year average (1981-2010) is 54 inches, so AccuWeather's range falls between 40 and 67 inches. .
