Does your location usually experience its coldest day of the year in early, mid, or late winter? Find an answer with this map based on weather observations between 1991-2020.
Many networks across the U.S. collect air temperature and precipitation observations we use to characterize these events. But only NCEI's U.S. Climate Reference Network (USCRN) was designed with lab-calibrated sensors--in triplicate--to ensure a high-quality, continuous record of U.S. climate.
