Map Shows States Getting Hit With 'Major, Sudden' Weather Phenomenon
Summary
A weather change called a sudden stratospheric warming (SSW) might cause colder-than-normal temperatures in parts of the U.S., especially in the Northern Plains, Midwest, and Northeast. This weather event is expected to happen around late November or early December and may bring Arctic air down into North America.Key Facts
- The National Weather Service predicts below-average temperatures in the Northern Plains, Midwest, Great Lakes, and the Northeast.
- The cold weather is related to a sudden stratospheric warming (SSW) event, which is disrupting the polar vortex.
- The SSW event is taking place earlier than usual and could cause significant weather changes.
- Areas most likely to experience below-average temperatures include states like North Dakota, Minnesota, Michigan, and New York.
- A different weather pattern from Alaska is also contributing to the cold weather by pushing cold air southward.
- Some forecasts show that November's cold weather might continue into December with high-pressure systems affecting the temperature.
- The phenomenon could potentially lead to a snowier start to winter in some areas of the U.S.
- Stratospheric warming events affect the polar vortex, which can bring colder weather as far south as Central Texas while the Southeast might see warmer temperatures.
