It May Be June, But Snow is Falling Early This Week in Parts of the West

Snow is coating parts of the mountain West for the beginning of June's second full week as an unseasonably cold air mass infiltrates the northwestern United States.

The National Weather Service (NWS) in Reno, Nevada, dubbed the wintry weather pattern "Juneary" in a tweet that showed snow falling as low as 5,800 feet in elevation in California's Sierra Nevada early Monday morning.

Measurable snow was also observed at Lake Tahoe on Monday morning. That only happens in June about every 5 to 10 years, the NWS said.

In the central Nevada town of Austin, up to 10 inches of snow had been reported as of Monday morning.

A trace of wet snow fell in Elko, Nevada, Monday morning, making it one of the latest occurrences of observable snow in records dating to 1889, according to the NWS.

Incline Village, Nevada, measured 3 to 6 inches of snow Sunday into Monday.

A webcam at Gilmore Summit in Lemhi County, Idaho, showed snow falling there early Tuesday morning. 

Snowfall Forecast

Cold air has moved in with a strong southward dip in the jet stream, or upper-level trough, that has swept into the Northwest as a result of a weather pattern flip.

This system will swing across the northern Rockies through Tuesday, bringing periods of rain and a few thunderstorms to much of the region and snow to some of the higher elevations.

Several inches of snow are possible across the highest elevations in northeast Utah, Idaho, southwest Montana and western Wyoming on Tuesday. Some locations could pick up more than 6 inches of total snow.

Snow is even possible down to the valley floors in parts of western Wyoming and in most of Yellowstone and Grand Teton national parks by early Tuesday. 

Slippery roads are possible with any snow that falls on high-mountain passes in the northern Rockies.

Additional Snowfall Forecast Through Tuesday

Half of the village of Big Sur, on the coast of central California, has lost its only access to the north following the demolition of the flood-damaged Pfeiffer Canyon Bridge along State Route 1 (also Rt. 1 or SR 1) on March 19. Although Rt. 1 to the south of Big Sur has reopened to traffic (after mud and rock slides were cleared) it is a long 70-mile journey along the windy but spectacular highway to Cambria, the next town of any significance where supplies can be had. CalTrans (California Department of Transportation) estimates it will take 6-9 months to rebuild a new bridge over the canyon.

By now, many of you have heard or read about the arrest of Ahmed Mohamed, a 14-year-old high school student from Irving, Texas. Ahmed was arrested because school officials called the police after he showed one of his teachers his homemade clock. Mistaken for a bomb, Ahmed was taken into custody, interrogated, shamed, suspended (still on suspension today, Wednesday), and reprimanded. All of this after it has been found that the "device" he brought to school was indeed, a homemade clock.
