Public Information Statement
Statement as of 6:45 PM MDT on June 7, 2009
A vigorous... cold storm system swept through the cowboy state
Saturday night and Sunday. This system produced widespread
precipitation across the region. There was plenty of cold air
for significant snowfall across the northwest and northern
mountains... including Yellowstone National Park. Snowfall totals
generally ranged between 5 and 10 inches. There was even enough
cold air for the lower elevations of the Big Horn basin to receive
snow. Snow was recorded in Greybull and Worland... but the bulk
of the snow in the Big Horn basin was across the Cody foothills
and extreme northern Big Horn County... where one to three inches
of snow fell. Accumulations in the lower elevations were mainly in
the grassy areas. Trace amounts of snow was also recorded in
Buffalo... Riverton... and in Lander.
Daytime temperatures were extremely cold for this time of year...
especially east of The Divide. Daytime highs on Sunday were
generally 30 to 35 degrees below average east of The Divide... and
about 10 to 20 degrees below average west of The Divide. Normal
highs for early June are generally in the 70s across the area.
