Meteorologists say temperatures could rise as much as 30 degrees above normal for late March. Areas including Texas, Kansas, Missouri, Illinois, and parts of the Dakotas may experience conditions that feel more like summer than early spring.
The extreme heat is being caused by a “heat dome,” a high-pressure system that traps hot air near the ground and limits cloud cover. In some parts of Texas and Nevada, temperatures could reach or exceed 100°F, while areas that normally see 40–60°F may rise into the 80s.
The National Weather Service has also warned about dry conditions and increased wildfire risk. Several cities in the Southwest have already broken daily temperature records, and officials are urging people to stay hydrated, limit time outdoors, and remain alert as the heat continues to spread.
