Report #23                                   Weekly Snow Report                             May 20, 2019

 

Greetings. This is the 23rd Snow Report for Water Year 2019 (2018-2019 snow season). Currently the state’s SNOTELs are reading 111% of median with a basin high of 185% and a basin low of 0%. Last year the state was at 90%, and at 159% in 2017. The map may differ slightly from the table depending upon how many stations were reporting at the time. This report and a map displaying basin SWE percentages of median for the state may be found at: http://www.wrds.uwyo.edu/wrds/nrcs/nrcs.html.

 

For information on the use of median vs. average go to http://www.wcc.nrcs.usda.gov/normals/median_average.htm

 

SNOW WATER EQUIVALENT AS PERCENT OF MEDIAN. The following table shows the percent of median for today, the 2 previous weeks, one year ago, and two years ago for Wyoming basins. Normal (median) is based on all reporting SNOTEL sites in the basin with calculated medians (newer SNOTEL sites do not have medians figured), but does not include manually measured snow courses. The statewide SNOTEL percent of median is a percent of median using all SNOTEL sites in Wyoming with calculated medians. The weighted state average is figured using the area of basins (square miles). The reference period for computing medians is the 30-year period 1981 through 2010.
