Wyoming – NRCS
Report #18 Weekly Snow Report Apr
15, 2024
Good day to all.
This is the 18th Snow
Report for Water Year 2024 (2023-2024 snow season). Currently the state’s
SNOTELs are reading 92% of median with a basin high of 111% and a basin low of 21%.
Last year the state was at 124%, and at 85% in 2022. 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 calculated by averaging medians for all stations associated
with Wyoming basins. The weighted state average is figured using the area of
basins (square miles). The reference period for computing medians is the
30-year period 1991 through 2020.
