...Final Storm Snowfall and Peak Wind for December 28-30...

Periods of heavy snowfall occurred across Yellowstone National Park,
and the Absaroka Mountains from Thursday night through Saturday
morning. At the same time very strong mountain top winds were
observed as well as between Rock Springs to Casper. An Arctic cold
front pushed south, east of the Divide Friday with bitter cold
temperatures in the single digits above and below zero. South of
this Arctic front unseasonably warm temperatures were observed
Friday with Rock Springs tying a record high of 47 degrees. Another
surge of Arctic air on Saturday combining with a disturbance aloft
produced a line of moderate to heavy snow east of the Divide with
most areas seeing 1 to 3 inches of new snowfall.

Observations are collected from a variety of sources with varying
equipment and exposures. We thank all volunteer weather observers
for their dedication. Not all data listed are considered official.

Note: SnoTELS (Snow Telemetry) are remote sensing sites in high
mountain watersheds. Snowfall data from SNOTELS are estimated based
on snow water equivalent.
