'Major, Sudden' Weather Phenomenon Could Soon Impact US
Summary
A sudden stratospheric warming event could disrupt weather in the U.S. soon, causing temperatures to drop below average in some regions. This atmospheric phenomenon may destabilize the polar vortex, leading to cold Arctic air moving south into North America. The expected weather shift could bring early winter conditions to parts of the U.S. by late November or early December.Key Facts
- A rare atmospheric event, sudden stratospheric warming (SSW), is expected to occur later this month.
- This event can disrupt the polar vortex, a low-pressure area above the Arctic that affects winter weather.
- A weakened polar vortex can cause cold Arctic air to move into the United States.
- The phenomenon may start affecting the U.S. in late November, potentially the earliest in nearly 30 years.
- Areas likely to see a temperature drop include the Midwest, Plains, and Ohio Valley.
- The ongoing La Niña weather pattern may complicate forecasts and influence weather conditions.
- Past SSW events have led to significant cold waves and winter storms in the U.S.
- Predicting exact impacts and duration of the cold weather remains challenging due to various influencing atmospheric factors.
