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. In California, people are already feeling March heat. Sunny days with temperatures around 90 degrees 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. South of California, a powerful high‑pressure system known as a heat dome will cover the Southwest. Forecasts say Phoenix could see 100‑plus degree 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.Meanwhile, a cold air mass from the polar vortex will push far south. The Midwest and East will experience temperatures that 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. In Texas and Oklahoma, strong winds up to 60 mph are expected. These gusts increase 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 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. Scientists say 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. The situation looks dramatic, but the first day of spring is still ahead. After that, weather should gradually stabilize.
