January precipitation along many of the major watersheds across Wyoming was below to much below average. The only exception was across the Wind and Tongue Basins--where precipitation totals were near to just above normal.
Snow water equivalents (SWEs) in Wyoming mountain snowpack remained 70 to 80 percent of average throughout January. However, SWEs across the Larmie Basin remained near 100 percent of normal.
Snowmelt streamflow volumes are expected to be below normal across a majority of watersheds in Wyoming. Near normal snowmelt streamflow volumes are forecasted for the Laramie Basin.
