21.5" of snow. "This storm was known as the "Thanksgiving Blizzard" and was also accompanied by epic cold, with temperatures dipping into the teens and 20s, according to the Farmer's Almanac. What made this storm particularly unique is the fact the snow stuck around for 63 days, and snow removal cost the city $1.5 million." - 9News

"The Blizzard of 1887 was just one part of an absolutely brutal winter. Cattle herds across the plains were decimated. Spoiled by previously mild winters and picture-perfect summers, ranchers in Wyoming and Montana had overstocked their lands. They were completely ill-prepared for the coming winter. For months, low temperatures, high winds, and record snowfall in Wyoming made it a battle to keep cattle fed. When a huge storm began in January, over an inch of snow fell every single hour for over 16 hours straight. Ranchers had no way to easily access their already fragile herds. The small bits of grass that the cattle had available to them was covered in snow and ice. They had no way to feed. In the end, hundreds of thousands of cows starved to death by the time spring arrived and the pastures were thawed." - Only In Your State
"The winter of 1886-1887 brought one of the most significant early storms recorded. The snow came early and grew very deep. Then, a freak thaw turned much of this to water. Cold weather moved back in, freezing the thawed liquid into a crust of ice, which prevented cattle from getting through to the forage underneath. These conditions, accompanied by a blizzard of unusual severity, caused a loss of more than 50 percent of the state's livestock. The snow was 6 feet deep on the level between Mountain Home and Woods Landing. On February 12, 1887, the storms were still raging over the state, and the snow was packed so hard that stages could drive over it. Trains were stalled on their tracks." - WY Hazard Mitigation Plan 2021-2026

"The surprising "Siberian Express" storm of 1933 was a system that crossed into the United States after wreaking havoc in Russia. It ended up being one of the worst natural disasters in Wyoming history. The storm was so brutal and cold that it set a low temperature record of -66 F in Yellowstone National Park. The bone-chilling cold was a threat to wildlife, livestock, and Wyomingites. To this day, the cold weather records set during this storm have yet to be broken." - Only In Your State

"Most blizzards come in strong and head out quickly. Wyomingites may be stunned and left shoveling pathways to move, but they tend to be fairly short-lived experiences. In 1955, though, a blizzard hit Sheridan and stayed for THREE days. Each day dropped over a foot of snow throughout the region. This storm earned its place in history books for its record snowfall in Wyoming." - Only In Your State

"A powerful winter storm impacted a large part of southeast Wyoming and the western Nebraska Panhandle on February 22-24, 2017. The storm originated over eastern Siberia February 15, and intensified as it tracked across the Gulf of Alaska." ... "Days preceding the storm were warm and dry, characterized by temperatures in the 60s and lower 70s. As the cold front passed, high temperatures at Alliance, Nebraska, fell from 73 degrees on February 21 to 34 degrees February 23. The snow began for areas west of the Laramie Range on the afternoon of February 22, and spread east of Interstate 25 early in the morning on February 23. Snowfall rates in excess of 2 inches per hour were observed before diminishing in the evening and overnight February 24. A broad swath of 12+ inches of snow was reported, including a 20-mile wide band of 20 to 25 inches extending from near Wheatland, Wyoming, east through Torrington, Wyoming, and Alliance, Nebraska. The dry air shown by the numerical models caused a sharp cutoff in snow amounts to the south, with only 2 to 5 inches along the Interstate 80 corridor from east of Cheyenne, Wyoming, to Sidney, Nebraska. One to three inches of snow fell in and around Laramie. In addition to the snow, gusty northerly winds resulted in considerable blowing and drifting snow, especially across western Carbon County, Wyoming, with blizzard conditions around Muddy Gap. This storm resulted in major impacts to transportation, resulting in numerous road closures across a large part of the region." - National Weather Service

Presidential Disaster Declaration. "On October 4-5, 1998, 8 to 12 inches of heavy, wet snow fell across eastern Converse County and Niobrara County. The heavy snow downed trees and power lines. Ice buildup was up to 6 inches around many power lines. The build-up of ice around the power lines, along with 40 mph winds, caused 200 power poles to snap. Four thousand people were without power for up to five days in the Lusk, Manville, Van Tassell, and Lance Creek areas. Interstate 80 between Cheyenne and Laramie was closed due to near zero visibilities." - WY Hazard Mitigation Plan 2021-2026

Presidential Disaster Declaration. "On November 1, 2000, an intense winter storm brought high winds and heavy, wet snowfall to portions of northeastern Wyoming. In Crook and Weston counties, snowfall rates were one to two inches an hour. Snowfall totals in the plains were from 4 to 8 inches, while in the Bear Lodge Mountains, totals were from 8 to 24 inches. The Four Corners area in northeastern Weston County reported the most snowfall at 24 inches. High, sustained winds up to 40 mph with gusts to 60 mph caused blizzard conditions and toppled 600 power poles. Seven thousand people were without power; almost 15 miles of lines had to be replaced. The city of Moorcroft had more than 150 stranded semi-trucks after the interstate was shut down. In Campbell County, the temperatures were too warm for snow and rain fell throughout the day, but high winds were reported with gusts more than 50 mph at times. The highest gust in Campbell County was 64 mph at Echeta." - WY Hazard Mitigation Plan 2021-2026

"On October 16, 2016, strong, moist westerly flow off the Pacific Ocean brought abundant moisture to the mountains and valleys of western Wyoming. The precipitation fell as snow in the mountains, with the heaviest snow of 12 to 18 inches falling in the Salt River, Wyoming, and western Wind River ranges. The position and strength of a jet streak helped to produce and sustain persistent snow in a swath from Big Piney to Pinedale in Sublette County. Snowfall rates reached up to 2 inches an hour during the late evening of Sunday, October 16, and early morning hours of Monday, October 17. Totals within this heavy snow band ranged from 8 inches to 15 inches with the greatest totals from around Daniel to Pinedale. In Big Piney, the heavy, wet snow caused the collapse of a school bus building roof resulting in $15,000 in damages. East of the Continental Divide the story was strong downslope wind. Wind gusts in the Lander Foothills topped 70 mph with a peak of 80 mph along the North Fork of the Popo Agie River. The strong winds blew over a tree in a Lander residential area." - WY Hazard Mitigation Plan 2021-2026

"On February 6, 2017, a combination of a strong Pacific trough and cold front, an ample supply of moisture combined to bring very heavy snow to much of western Wyoming. The highest amounts fell in the Tetons where almost 3 feet of new snow occurred at the Jackson Hole Ski resort. Heavy snow also fell in the Salt and Wyoming Range where 32 inches of snow occurred at the Indian Creek SNOTEL. Other heavy snowfall amounts included 25 inches at Deer Creek in the Wind River Range, 18 inches at Two Oceans Plateau in Yellowstone, 16 inches near Wilson, and 8 inches in Cody Alpine. The heavy snow combined with gusty winds to produce very low visibility and avalanches that shut down many roads including Teton Pass, Hoback Junction and South Pass. In Jackson, the heavy snow load caused the collapse of the roof onto the Sears Department Store. In addition, strong winds occurred on the evening of the 7th. These strong winds combined with heavy wet snow to down 17 power poles along Highway 390. This led to a power outage that lasted through the 11th. Near Teton Village, strong winds estimated over 70 mph, combined with heavy snow to down 17 power poles which led to a power outage lasting through the 11th. Jackson Hole Ski resort was closed through Monday the 13th. Meanwhile, strong wind occurred east of the Divide and across southern Wyoming. The maximum wind gusts included 96 mph at Camp Creek in the Green and Rattlesnake Range, 72 mph near Lander and 65 mph along Outer Drive south of Casper." - WY Hazard Mitigation Plan 2021-2026
