Analysis - Snow Today

April 3, 2025

Snow conditions less volatile than the stock market

Snow-covered area in March across the western United States was 8 percent below average, ranking seventeenth in the 25-year satellite record. Snow cover duration was just above the twenty-fifth percentile. Snow albedo, also known as snow brightness, started low in early March and then oscillated between high, then low, and then high during the month. Snow water equivalent (SWE) relative to average showed little change during the month, despite SWE gains at many stations across the region.

Snow Today is a NASA-funded research project that examines where snow is present, where it has snowed recently, and how much water is in the snow, while also comparing between snow today, snow yesterday, snow last year, and snow over the last few decades.
