From Glossary of Meteorology
A period of abnormally little snowpack for the time of year, reflecting either below-normal cold-season precipitation (dry snow drought) or a lack of snow accumulation despite near-normal precipitation, usually when warm temperatures prevent precipitation from falling as snow or result in unusually early snowmelt (warm snow drought).
