The Green River Basin continues to have a wide distribution of water supply outlook conditions. Storm patterns favored the basin below Flaming Gorge helping to increase the forecast for those areas. Conditions upstream from Flaming Gorge continue to be below average.

January precipitation was above average at 115%. This brings the seasonal precipitation to near average conditions throughout many basins. However, the snowpack remains below average at 80% basin wide. The below average soil moisture states within the model continue to decrease objective guidance values. While NOAA's Climate Prediction Center indicates the potential for wetter than normal conditions over the next 30 days, shorter term weather models do not indicate significant precipitation in the Upper Green River Basin over the next 10 days. This influenced the decrease in the coordinated forecast for many points. Like December, monthly inflow to Flaming Gorge was near 50% of average.

Monthly precipitation for January was 145% of average in the Yampa River basin. Snowpack increased from 85% of basin average on January 1, to 110% on February 1. The Elk and Little Snake drainages show the best conditions with some stations near their seasonal maximum. Due to these improved conditions, forecasts increased throughout the Yampa and White Basins.

January precipitation was 165 % of average. The snowpack, which had high variability at the end of December, has increase to 120% of average as of February 1. All stations within the Uinta Basin have average to above average conditions. As a result, forecasts increased throughout the basin.

Similar to the Yampa and Duchesne, January precipitation has brought the snow pack from below average to above average conditions in the Lower Green. Basin wide, snow pack is 120% of average as of February 1. As one would expect, forecasts for the Eastern side of the Wasatch Plateau increased to a basin median of 105%.

It's worth noting that monthly precipitation reported by lower elevation gages in the San Rafael Swell region was below average for January. However, this area does not normally contribute substantial snow melt volume to forecast points within the Lower Green Basin.

Differences between the full period forecasts and the residual forecasts may not exactly equal the actual observed volumes due to rounding conventions (see Definitions section).
