8. Western SnowA significant winter storm brought heavy snowfall to areas of Montana, Wyoming and Idaho October 10-12. The snowy conditions brought record snowfall and gusty winds knocked down trees and power lines and reduced visibility. Several Wyoming counties reported as much as 33 inches of snow. In Montana, the city of Red Lodge recorded its highest snowfall total during a 24-hour period when 42 inches of snow fell.Global Warming Link: The snowstorm in the northwest U.S. in October was exceptional for so early in the season. A strong, warm ridge of high pressure aloft set the stage for the pattern that produced the storm and is consistent with many other such scenarios in recent years that are directly related to the larger-scale warming. Expert: KevinStu Ostro, sostro@weather.com, 404-210-7105 Consensus Science: "A widespread increase in annual precipitation is projected ... over most of the North American continent."
