Across much of the Western United States, winter 2026 was the year the snow never came. Many ski resorts got by with snowmaking but shut down their winter operations early. Fire officials and water supply managers are worried about summer.
Where I live in Boise, Idaho, temperatures hit the low 80s Fahrenheit (high-20s Celsius) in mid-March. The same heat dome sent temperatures soaring to 105° F (40° C) in Phoenix.
Ordinarily, water managers and hydrologists like me who study the Western US expect the mountain snowpacks to be at their fullest around April 1. Snowpacks are natural reservoirs of water that farms and communities depend on through the hot, dry summer. Their snow water equivalent, meaning the amount of liquid water in the snowpack, is seen as a bellwether for water supplies.
