Precipitation numbers varied between 188 percent of normal over the Crow/Lodgepole Creek Drainages (Southeast Wyoming) to near 77 percent of normal over the Upper Bear Basin (Southwest Wyoming).  Current water year (October 2013 - January 2014) precipitation across Wyoming is nearly 130 percent of average.

Mountain snowpack across Wyoming was 115 to 120 percent of normal by early February.  Snowpack "water" numbers and/or SWEs continued to be the highest across northeastern Wyoming—varying between 125 to 150 percent of average.  SWEs were the lowest across southwestern Wyoming---varying from 85 to 100 percent of normal.

Near normal (90 to 110 percent) snowmelt streamflow volumes are expected across almost all major basins across Wyoming.  Above average streamflow volumes continue to be expected across the Powder River Watershed.  Below average streamflow volumes during the upcoming snowmelt season continue to be forecasted for the Lower Green, Sweetwater, and lower portions of the Wind River Basin.

Reservoirs storages across Wyoming remain slightly below average for February.
