A burst of unusual March heat is hitting the United States this week and into next, busting previous monthly heat records by wide margins. While heat is most acutely felt by people exposed to it, graphics and charts convey the scale of this extreme event. Temperatures in the West remain far above what's typical for March, a sign the early season heat is not letting up. Compared with the average highs for March between 1991 and 2020, temperatures across some parts of Oklahoma, Nebraska, northern Texas and South Dakota are reaching at least 20 degrees Fahrenheit (11 degrees Celsius) above normal.
