Weather models are predicting severe cold and multiple chances of major snowstorms across various regions. Here are some key details:
- Severe Cold: Arctic air is expected to plunge into the central and eastern U.S., bringing sub-zero temperatures. This cold air originates from regions like Alaska, Canada’s Arctic, and even Siberia.
- Major Snowstorms: The North Atlantic Oscillation (NAO) is in a negative phase, which can lead to persistent cold temperatures and the potential for East Coast snowstorms. This pattern often results in low-pressure systems that bring snow, rain, wind, and coastal flooding.
- Atmospheric Rivers: The West Coast may experience repetitive atmospheric rivers, which are narrow plumes of moisture that can bring heavy precipitation and snowfall.
- Weather Patterns: Meteorologists are tracking several extreme weather patterns, including arctic cold building in the heart of winter and weather patterns near Greenland that favor East Coast winter storms.
