Widespread Western Snow Brings Dazzling Vistas And Dangerous Roads
A vast system that brought snow and cold to normally milder cities including San Francisco, Seattle, Salt Lake City and even Las Vegas was moving eastward into the central part of the country on Wednesday. The country's midsection from New Mexico to Michigan was blanketed in frozen precipitation. The system caused treacherous travel, shuttered schools and even closed ski resorts.
"A pretty strong mid- and upper-level trough" is responsible for the system that brought significant snowfall to the West this week, Marc Chenard, meteorologist at the Weather Prediction Center, told NPR. He added that a large area is seeing "some type of wintry impact."
Las Vegas saw snowfall on Tuesday as well as something even more exotic: graupel. The National Weather Service says the term applies to snowflakes that "collect supercooled water droplets on the outer surface," similar to small hail.
🤓 NERD ALERT: What IS falling from the sky? We are getting this question a lot this morning. Mostly likely- most places are seeing GRAUPEL today, but how is that different from other types of frozen precipitation #nvwx #cawx #cawx #vegasweather #Science pic.twitter.com/cjvQevAZyc— NWS Las Vegas (@NWSVegas) February 5, 2019
Law enforcement joined in the snow day action outside Seattle. Police in Duvall, Wash., had fun with a video about "a group of suspicious characters in a local park," actually a bunch of kids with snowballs. Police engaged them in a snowball fight, but their riot shield proved no match to the kids' barrage and it ended with the police shouting "tactical retreat" and conceding defeat.
School districts across Utah canceled classes Wednesday amid several inches of snow. The Salt Lake Tribune reports it was the first time in some two decades that school was called off in Salt Lake County.
By early Tuesday evening, Utah Highway Patrol reported around 100 crashes across the state.
A Rich County deputy was investigating one of the crashes at a truck ramp earlier in the day when a semi coming down the grade lost control and struck him. The deputy suffered serious, but not life-threatening, injuries, according to the Utah Department of Public Safety. The tractor-trailer driver suffered minor injuries.
Citing the risk of avalanches, the Utah Department of Transportation shut down Little Cottonwood Canyon, restricting access to Alta and Snowbird ski resorts.
"There are so many people who want to take advantage of the fresh powder," John Gleason, UDOT spokesman, told the Tribune. "We have to choose safety over convenience."
Back in California, a few flakes were spotted falling in San Francisco, a rarity, with more snow accumulating in the surrounding higher elevations.
Farther inland, several feet of snow fell in the Sierra Nevada. Mammoth Mountain reported accumulations of 10 feet, and nearby June Mountain temporarily shut down operations.
Another 2-3 feet of snow brings the current storm total to 79-117”! That’s just about 10 FEET since Saturday. 🚨Main Lodge and @junemountain will remain closed today due to blizzard conditions. 🚨Snowfall, strong & damaging winds are expected today with clearing skies Wed/Thurs. pic.twitter.com/j5v2ndNvhb— MammothMountain (@MammothMountain) February 5, 2019
At California's Yosemite National Park all roads were closed Tuesday into Wednesday. Park officials urged the visitors already there to remain indoors "to avoid falling trees."
All roads within Yosemite will remain closed to all traffic tonight due to snow and falling trees. We will re-evaluate conditions tomorrow morning for possible afternoon opening.— Yosemite National Park (@YosemiteNPS) February 6, 2019
As always, the best way to check road conditions is by calling 209/372-0200 (then 1, 1). pic.twitter.com/whVLqP6wWK
By the time the system moves into the East as of Thursday night, Chenard says, warmer air means it will turn mostly to rain.
