Quick Synopsis:


Mountain snowpack and associated snow water equivalents (SWEs) across Wyoming were generally below average by the middle of January.  SWEs at the peak snowmelt runoff elevations (8,000’ – 9.500’) were the highest across northwestern Wyoming at 100 – 115 percent of normal; while across southeastern Wyoming, SWEs were 50 to 75 percent of average at the peak snowmelt runoff elevations.
