Late May snowfall of 13 inches hits mountains near Sochi, Russia

Sochi snow
In Sochi in the mountains, the snow, the thickness of the cover at the top of rose Peak is 13 inches. Precipitation become possible due to the cooling to minus one degree, which is rare for spring, according to the mountain resort "Rosa Khutor".

As of mid-day Saturday in the lowlands, it was observed 70 mm of snow precipitation that exceeds the norm.

At a height of 2.3 thousand meters above sea level thickness of snow cover exceeds 10 cm.

Snow went to the level of 1.23% of the country, say forecasters. Experts said the reason for the sharp decline of the ambient temperature is the invasion of Northern temperate air masses moving cold atmospheric front passed through the region the night before. In the third decade of May such sharp temperature fluctuations occur very rarely. The increased precipitation occurred on the evening of May 22.

Winter is still hanging on at the higher elevations Friday.
While warm weather and longer days in the Valley are sure signs summer is on the way, winter is hanging on at higher elevations.

Those driving the Okanagan Connector Friday morning will find significant snow on the highway, and it continues to fall. About nine centimetres of snow fell on the Pennask Summit through the night, while the Coquihalla saw a light dusting of snow that has since been melted by rain.

Webcams on the Connector shows the snow has also fallen on the Elkhart area, but the lower-elevation Brenda Mine region remains clear.

And while warm conditions have been rapidly melting snow at Big White, getting the mountain ready for its June 26 kick off to the mountain bike season, snow also fell at the resort overnight.

The majority of North America has suffered an historically chilly start to 2020, and the cold isn't letting up, continuing through May and busting hundreds of low temperature records as it goes.


The month of May has been a chilly one thus far at Reagan National Airport, located in Virginia on the border with D.C., with the station experiencing its third coldest start to May since records began back in 1966.

According to local news site wjla.com, the area has, through the 19th, seen 14 days below average, one day at average, and only four days above average.

"Our average high for the first 18 days of the month was just 68.8 degrees, with an average low of 50.4," reads the wjla.com article. "Together, that puts us at an average monthly temperature of 59.6 degrees, which is 4.4 degrees below normal."

Several inches of snow Wednesday morning, May 20, 2020.
We all woke up to rain outside Wednesday morning as widespread moisture rotates around a low pressure center in Idaho. While we've had significant rain in the valley, rain transitioned over to snow overnight at Bogus Basin.

The snow stake at Bogus Basin shows several inches this morning with a blanket of white across the base area. A weather station near the Nordic Center reports one inch of precipitation in the past 24 hours. That would've equated to about a foot of fresh snow in winter months.

Mid-May winter storm brings fresh snow to Lake Tahoe

Snow in Lake Tahoe in May? ABC7 News Meteorologist Drew Tuma is tracking fresh snow falling in the Sierra Monday.

"Flakes are flying," said Tuma. "While it's weird that we are talking about snow this late in May, it's not unusual to get these light storms moving through the Sierra as we end our snow season."

There's a Winter Storm Warning in effect until midnight Monday with snow levels dropping to about 6,000 feet.

"We are talking about 3 to 6 inches of snow. Some areas in our highest peaks could see up to a foot of snow," said Tuma. "We are still talking about snow falling in the Sierra, that's good news. We still want to add to our snow pack, which is below normal for this time of the year."

Global cooling 4,200-years ago spurred rice's evolution

A major global cooling event that occurred 4,200 years ago may have led to the evolution of new rice varieties and the spread of rice into both northern and southern Asia, an international team of researchers has found.

Their study, published in Nature Plants and led by the NYU Center for Genomics and Systems Biology, uses a multidisciplinary approach to reconstruct the history of rice and trace its migration throughout Asia.

Rice is one of the most important crops worldwide, a staple for more than half of the global population. It was first cultivated 9,000 years ago in the Yangtze Valley in China and later spread across East, Southeast, and South Asia, followed by the Middle East, Africa, Europe, and the Americas. In the process, rice evolved and adapted to different environments, but little is known about the routes, timing, and environmental forces involved in this spread.

In their study, the researchers reconstructed the historical movement of rice across Asia using whole-genome sequences of more than 1,400 varieties of rice — including varieties of japonica and indica, two main subspecies of Asian rice — coupled with geography, archaeology, and historical climate data.

Rare late night frost in the Netherlands

For the second night in a row, it has frozen in De Bilt in the night from Thursday to Friday.

In the Utrecht city, where the national main measuring station is located, it cooled down to -1.2 degrees C. The night before it was -1.0 degrees C.

Such late night frost in De Bilt is special, according to weather agency Weeronline.

Only in 1909, 1941, 1946 and 1973, just like this year, were there two or more frost nights after May 10 in De Bilt.

The sun has entered a 'lockdown' period, which could cause freezing weather, famine

Our sun has gone into lockdown, which could cause freezing weather, earthquakes and famine, scientists say.

The sun is currently in a period of "solar minimum," meaning activity on its surface has fallen dramatically.

Experts believe we are about to enter the deepest period of sunshine "recession" ever recorded as sunspots have virtually disappeared.

Astronomer Dr. Tony Phillips said: "Solar Minimum is underway and it's a deep one."

Comment: It would appear that a "super grand" solar minimum is one factor in a confluence of cycles that are upon us: Also check out SOTT radio's:
