Storm brings near white-out conditions to Snoqualmie Pass, Washington, with at least 18 inches of snowfall

trucking
It's Friday the 13th and those who had plans to travel over the mountain passes might be cursing their luck as a strong winter-type storm pummeled the Cascades.

Heavy snow combined with blustery winds to bring near white-out conditions to I-90 along Snoqualmie Pass, according to the WSDOT.

Multiple spinouts have forced occasional closures of the pass. Eastbound lanes were shut down just after 8:30 a.m. for about an hour to clear wrecks, WSDOT officials said while westbound remained open with chains required. Earlier, multiple spinouts closed a 37-mile stretch of I-90 through much of the mountains late Thursday night into the wee hours of Friday morning, reopening just after 1 a.m. with chain requirements for all vehicles except 4 wheel/all wheel drive.

Recap: The changing jet stream and global cooling

the changing jet stream


Studying the JET STREAM has long been an indicator of the weather to come, and to study the jet stream attention must turn to the SUN.


When solar activity is HIGH, the jet stream is tight and stable and follows somewhat of a straight path. But when solar activity is LOW, that meandering band of air flowing 6 miles above our heads becomes weak and wavy, it effectively buckles which diverts frigid Polar air to atypically low latitudes and replaces it with warmer tropical air.

The jet stream reverts from a Zonal Flow to a Meridional Flow and, depending on which side of the jet stream you're on, you're either in for a spell of unseasonably cold or hot weather and/or a period of unusually dry or wet conditions.

10 inches of snow in Minnesota, damaging winds in Wisconsin

SNOW
A November storm has dumped as much as 10 inches (25.40 centimeters) of snow in Minnesota and whipped up damaging winds in Wisconsin where tens of thousands were left without power.

The Minnesota State Patrol handled hundreds of crashes and spinouts as snow piled up late Tuesday. Between 4:30 and 9:30 p.m., troopers responded to 176 crashes, 156 vehicles that had spun out or slid off the road, and 11 jackknifed semitrailer trucks. Twelve people were hurt in the crashes, but no weather-related deaths were reported, the patrol said.

The National Weather Service record 5.5 inches (13.97 centimeters) of snow at Minneapolis-St. Paul International Airport with Brainerd picking up the most snow with 10.1 inches (25.65 centimeters).

In northeastern Minnesota, Grand Rapids picked up 9.5 inches (24.13 centimeters), the weather service said.

Officially Denver only received a trace of snow on Monday but most neighborhoods in the metro area measured 1 to 3 inches. Meanwhile some mountain areas saw almost 3 feet of snow from the same storm system.

The foothills including areas like Conifer, Central City, and Nederland saw as much as 6 inches of snow on Monday.

No location in Colorado seems to have received as much as the eastern San Juan mountains near Pagosa Springs. Wolf Creek ski area reported a total of 34 inches of snow from Saturday through Monday. Wolf Creek is now open 7 days a week along with Keystone and Arapahoe Basin who quietly opened on Monday.

Other ski areas that are no quite open also saw large amounts of snow on their snow stakes. Winter Park has received at least a foot of snow ahead of their scheduled opening on November 30.

Susitna Valley in Alaska sees up to 19 inches of snowfall through the weekend

Anchorage police say dozens of collisions and vehicles in distress were reported after a snowy, icy weekend Nov. 9, 2020.

Anchorage police say dozens of collisions and vehicles in distress were reported after a snowy, icy weekend Nov. 9, 2020.
Winter weather has arrived, and it skipped the subtlety when coming to the Northern Susitna Valley over the last two days. The weekend's winter storm warning promised ten to eighteen inches of snow, and the storm that arrived delivered at the high end of that forecast.

The National Weather Service's snow gauge in the Northern Susitna Valley is at Su Valley Junior-Senior High School. According to that gauge's data, the area went from zero snow cover late last week to just shy of a foot-and-a-half on Monday.

Areas throughout the Susitna Valley saw snowfall in excess of one foot over the last three days. Hatcher Pass recorded fourteen inches of snow, and Chulitna River Lodge saw nineteen inches.

The sudden, heavy snowfall complicates travel in the Northern Susitna Valley. According to Alaska 5-1-1, the Parks Highway from just north of Wasilla to the Talkeetna Spur Road is classed as difficult driving conditions. The Spur road, itself, is also listed as "difficult." North of the Talkeetna turnoff, the Parks Highway is listed in "Fair" driving condition.

Snow is falling across the Okanagan Valley as winter arrives in full, and Apex Mountain is gearing up for what looks to be their earliest start yet.

If the weather holds, the slopes of Apex will be seeing skiers on the mountain earlier than ever. They won't be members of the public, but athletes who have arrived to practice on the course.

The resort is still currently planning on a Dec. 5 opening to the general public, said the resort's general manager James Shalman. However, if the weather stays cold and if there is enough snow that may be sooner.

Apex received close to 30 cm of snow over the last 24 hours and if it holds they'll have the World Cup course open by the end of the week.

Cold temperature records broken in California

Cold records broken in California
After months of searing temps and wildfires, a cold snap has finally arrived in California.

Back-to-back weekend storms on Friday and Sunday brought chilly temperatures, rain and snow to much of the state after months of hot weather that fueled enormous wildfires.

Case in point: A total of 18 inches of snow even blanketed Sierra-at-Tahoe ski resort, followed by 10 inches at Sugar Bowl over the weekend, prompting a travel advisory throughout the Sierra Nevada.

Daytime temperatures dipped to the high 50s and freeze warnings and frost advisories were issued for some inland valleys during overnight hours.

And on Monday, cold temperature records were set. It was 38 degrees at the Oakland Airport Monday morning, breaking a 2009 record when it was 41 degrees. Gilroy also set a record at 31 degrees on Monday, breaking a 1986 record when it was 34 degrees.

Record cold and snow plunge into northern Nevada

record
We saw it coming for days, but it still was a shock to feel the extreme cold after such a warm fall.

Many awoke to the double whammy of record snow, then the cold Sunday and Monday.

We saw several kinds of records fall across the area. Single day snowfall records were broken in Reno, Carson City, and Yerington just to name a few.

Most of the area saw a general 3 to 5 inches and that was historic for the date. We normally see our first snowfall around the middle of November, but what's so unusual is the amount that fell.

Las Vegas breaks record-low high temperature set in 1946, days after record heat

The Las Vegas Valley set another weather record on Sunday, but this time it involved the cold.

The National Weather Service recorded a high temperature of 54 degrees, 1 degree lower than the 1946 record of 55.

Last week, Las Vegas had three consecutive days of record-breaking heat. The weather service observed highs of 86 degrees on Wednesday, Thursday and Friday.

Though some parts of the valley on Sunday saw traces of rain and hail, meteorologist Andy Gorelow said McCarran International Airport, where the weather service takes its measurements, stayed dry for the 202nd consecutive day.

Several roads were shut down in Saskatchewan and Alberta as a result of the poor visibility from the blowing and drifting snow on Sunday.

The potent weekend snowstorm on the Prairies brought blizzard conditions with heavy snowfall that buried cars and made travel dangerous and nearly impossible in several regions.

There have been reports of 20-40 cm of snowfall near Edmonton, Alberta and a wind gust hitting 102 km/h was recorded in Ardenville. In Kindersley, Saskatchewan 47.6 cm of snow piled up, making it the snowiest November day on record and the largest two day snowfall event for the city.


Several roads shut down in Saskatchewan and Alberta as a result of the poor visibility from the blowing and drifting snow. Police urged people to just stay home, but said if they must head out on the roads, they should go slowly and take extra precautions.
