Weather Wildcards: Heat, Snow, Storms and More Across the U. S.

A strange mix of weather is happening at once in America. Warm, dry air and hot temperatures are moving into the Southwest while cold, icy fronts hit the Midwest and East. At the same time, heavy rains and a big storm bring snow to the Great Lakes region.

California: March Heat Already In Full Swing

• Sunny days with temperatures around 90 °F have forced residents to stay in the shade and wear light clothing.
• A runner from Los Angeles said he had to cut his usual 5‑mile jog short because the heat was too intense.

Southwest: A Heat Dome Threatening Record Days

• A powerful high‑pressure system will cover the Southwest.
• Forecasts say Phoenix could see 100 +°F days as early as March 26— a record for that time of year.
• The heat will stay strong for several days, raising concerns because people are not used to such temperatures so early.

Midwest & East: Polar Vortex Pushes Cold Far South

• Temperatures drop into the single digits or teens.
• Cities like Minneapolis, Chicago, and even Atlanta could see lows in the 20s.
• A storm system will bring heavy snowfall to the Great Lakes, with some places expecting up to four feet of snow.
• A second storm could grow into a bomb cyclone, an unusually strong low‑pressure system that usually forms over warm oceans but here will tap into the cold air.

Texas & Oklahoma: Winds Threaten Wildfires

• Strong winds up to 60 mph are expected, increasing wildfire danger in dry areas.
• Nebraska’s governor has activated the National Guard to help fight more than 50 wildfires that have burned over 550 square miles.

Hawaii & Alaska: Persistent Rain and Extreme Cold

• Hawaii is battling a persistent, heavy‑rain event known as an atmospheric river. The rain has triggered flash flood warnings on Oahu.
• Alaska, normally cold in March, will be even colder than usual.

Science Behind the Chaos

• The jet stream—an invisible river of air that carries weather patterns—is behaving unusually.
• It is steep and deep, causing extreme temperatures to move quickly across the country.
• This pattern may be linked to climate change and shrinking Arctic ice.

Outlook

The situation looks dramatic, but the first day of spring is still ahead. After that, weather should gradually stabilize.
