Snowpack conditions in Nebraska vary across the state, with the majority of snowfall occurring in the western mountain ranges. The main mountain ranges that contribute to Nebraska's snowpack are the Pine Ridge, Wildcat Hills, and the Scotts Bluff National Monument. These areas receive the most snow due to their higher elevations and proximity to moisture sources. Snowmelt from these mountains contributes to the runoff rivers and watersheds that supply water to the state's reservoirs and irrigation systems.

Nebraska experiences a semi-arid climate, with cold winters and hot summers. Average snowfall ranges from around 20-30 inches annually, with higher amounts in the mountainous regions. Snowfall usually begins in November and lasts through March, with peak accumulation occurring in February. However, snowpack can vary greatly from year to year depending on weather patterns and climate oscillations.

Interesting facts about snow in Nebraska include the state's involvement in snow science research. The University of Nebraska-Lincoln's Conservation and Survey Division operates the Snow Survey Program, which collects and analyzes snowpack data to assist with water resource management. Additionally, the state has historically experienced severe blizzards, such as the Blizzard of 1949, which led to significant snow accumulation and transportation disruptions.
