A brief moment of high wind speeds were felt across the South Laramie Range on the 23rd. A Union Pacific Railroad sensor about two miles west of Buford measured a high wind gust of 58 mph. A moisten atmosphere and topographic forcing coupled with synoptic forcing aloft assisted in the accumulation of over a foot of heavy snow along the higher elevations of the Snowy Range Mountains by SNOTEL sensors.
