Drought conditions persisted throughout much of 2021 across several Western states, especially in Oregon and Washington. A summertime heat dome hovered for days over the Pacific Northwest and western Canada, breaking numerous temperature records. The extreme heat and dry conditions withered crops and forced the closure of the hydroelectric power plant in Lake Oroville, California, for the first time since it opened in 1967.

While much of the western United States suffered from record high temperatures and drought for much of 2021, heavy downpours inundated southern and central California for five days in January. Floods and mudslides damaged residential and commercial properties, vehicles, and infrastructure, while high winds caused power outages. Snow shut down roads at higher altitudes in the Sierra Nevada range.

Historic low temperatures and a winter storm struck states across the northwest, central, and eastern parts of the country. Temperatures fell to as much as 40 degrees Fahrenheit below normal in the parts of the Great Plains plains from Nebraska to Texas. The arctic front caused power outages, notably in Texas, where most of the deaths occurred. The event became the costliest U.S. winter storm on record.
