Snowstorm warning in Hawaii, record high temperature across the Americas | US weather

When December began, the normally mild snowstorm warnings to Hawaii and the lack of snow in the mountainous areas of Colorado were one of a series of bizarre weather forecasts and events in the United States.

Meteorologists attributed the latest batch of record-breaking extreme weather events to jet stream stagnation and the effects of La Niña weather patterns from Pacific cooling water.

For American meteorologists, winter begins on December 1st. However, on Thursday, December 2, 65 meteorological stations across the United States recorded record highs, with Springfield, Missouri reaching 75F (24C) and Roanoke, Virginia reaching 72F (22C). Cheyenne, Wyoming and Billings, Montana broke long-standing heat records on the 6th floor.

December records can also be found in parts of Canada and Montana. On Friday, parts of South Carolina and Georgia hit record highs.

In Washington, Seattle, Bellingham, and Quileute set 90-day rainfall records. Bellingham was hit by nearly two feet of rain. According to the National Weather Service (NWS), the Olympics and the Cascade Range have been hit harder, exceeding 50 inches in three months. Forks, Washington received more rain in 90 days than Las Vegas received in 13 years.

There was a blizzard warning at the Big Island Summit in Hawaii, with up to 12 inches of snow expected and gusts exceeding 100mph. But in Colorado the snow is gone.

Prior to this year, the first measurable snowfall in Denver was November 21, dating back to 1934, according to the NWS. There is a slight chance that it will snow on Monday night. However, since it hasn’t snowed since April 22, this is the third longest section in a snow-free city.

The jet stream, a river of air that moves the weather from west to east, has stopped. This means that more than two-thirds of the high pressure systems in the United States produce dry, warm weather, while some low pressure systems in streams bring rain to the Pacific Northwest. College Park, Maryland.

As the jet stream moves more or bends differently, rain and other extreme weather events will be less concentrated, Harley said. He added that this is a typical weather pattern in which the La Niña phenomenon occurs naturally.

Behind El Nino, La Niña is the cooling of parts of the Central Pacific that change weather patterns around the world. La Niñas brings more rain to the Pacific Northwest and tends to make the south drier and warmer.

Meteorologist Jeff Masters, the founder of Weather Underground, who currently works at Yale Climate Connections, said these extreme weather attacks occur more frequently as the world warms. However, scientists have not done the research necessary to attribute these events to anthropogenic climate change.

In Boulder, Colorado, meteorologist Bob Henson enjoyed riding a rare December bike on Thursday. Still, “I have a lot of anxiety about the lack of snow,” he said. “It puts you in a mental predicament. We enjoy warm weather, keeping in mind that warming the earth is not good.”
