January Graphical Wyoming Water Supply Forecast

...Water supply outlook and streamflow forecasts for Wyoming...from the National Weather Service and the Natural Resources Conservation Service...

October precipitation totals across central and western Wyoming were generally near to just above average...below average in eastern Wyoming.  Precipitation was below to well below normal for all of Wyoming during November.  Southeast Wyoming had well above normal precipitation during December, western Wyoming had near normal precipitation, and  central Wyoming had below to well below normal precipitation.  Snow water equivalents (SWEs) in the mountain snowpack across Wyoming fell to 70 to 80 percent of average by the end of December.

Snowmelt streamflow volumes forecasts in many watersheds west of the continental divide are expected to see normal to just below normal snowmelt streamflow runoff values during spring.  Below normal to well below normal snowmelt streamflow volumes are expected for the majority of the watersheds east of the continental divide.  The only exception is the Laramie Basin where near normal runoff volumes are expected.

The following graphic depicts preliminary streamflow volume forecasts for selected points:
