Washington, D.C. is preparing for a March that promises warmer temperatures, a welcome change after three months of colder-than-normal conditions. The Washington Post reports that the city will experience a significant warm-up, with temperatures climbing into the 70s°F (21-26°C) by the middle of next week. This warm spell, however, is not expected to last, as cooler weather is predicted to return by mid-March, leading to temperature fluctuations throughout the month.
