Tropical Storm Zeta and another storm system trekked through the Mid-Atlantic, bringing rain, snow, and gusty winds to the region from October 29 to 30. Spring was warmer and wetter than normal for the Southern Region. . There were several flash flooding events during the year. U.S. annual average temperature 2022 | Statista Globally, 2020 was the hottest year on record, effectively tying 2016, the previous record.

Hawaii, for the second year in a row, saw above normal temperatures that were in some cases record-breaking. The center of low pressure for this storm is the lowest known pressure in or around Alaskan waters. There were no areas of below-average annual temperatures observed across the Lower 48 during 2020. Temperatures across the Lower 48 in December 2020 (left), January 2021 (right), and February 2021, compared to the 1981-2010 average. October was mixed with respect to temperature, with three states (Arkansas, Oklahoma, and Texas) experiencing cooler than normal temperatures while three states (Louisiana, Mississippi, and Tennessee) experienced warmer than normal temperatures. During summer and fall, groundwater levels were also well below normal in many drought areas. Further east, in Californias Central Valley, Sacramento received 7.86 in (199.64 mm, 39% of normal) making it the fifth driest year since 1878. Louisiana experienced five landfalls: Tropical Storm Cristobal and Hurricanes Laura, Marco, Delta, and Zeta. Drought conditions expanded or intensified across much of the western U.S. and southern to central High Plains throughout 2020 with persistent above-average temperatures and precipitation deficits in place across much of the West. Allentown, Pennsylvania, and Harrisburg, Pennsylvania, had their least snowy seasons (October through May) on record. The five warmest years on record have all occurred since 2012. The three largest wildfires in Colorado history occurred during 2020: The Cameron Peak Fire, the East Troublesome Fire and the Pine Gulch Fire each exceeded the acreage burned by the previous record, the 2002 Hayman Fire. Despite Record Heat Waves, This Likely Won't Be - The Weather Channel The USCEI is an index that tracks extremes (falling in the upper or lower 10 percent of the record) in temperature, precipitation, drought and landfalling tropical cyclones across the contiguous U.S. A total of 13 tornadoes were spawned by Delta, including an EF-1 tornado that injured 2 people at a homeless shelter in Newton County, GA on October 10th. In many fields in southern Alabama, Hurricane Sally blew down the cotton crop when bolls had yet to open. The lowest annual precipitation total for any station (excluding CoCoRaHS) across the region was recorded in East Hill on St. Croix, USVI, which observed only 35.69 inches (907 mm) of precipitation. Several major storms affected the Northeast during 2020. UK: monthly daily average temperatures 2023 | Statista Temperatures were below normal in the Interior, Southcentral, and Southeast regions of Alaska. Based on preliminary analysis, the average annual temperature for the contiguous U.S. was 54.4F, 2.4F above the 20th century average. The U.S. Drought Monitor released on October 29 showed 47 percent of the Northeast in an extreme, severe, or moderate drought and 24 percent as abnormally dry. On October 7, a derecho produced a 320-mile (515 km) long path of damage from central New York to eastern New England. The damage pattern suggested that this tornado may have had multiple vortices, which can occur with the strongest tornadoes. Northern Delaware experienced some of its worst flash flooding in at least 15 years. The fewest number of reports occurred in South Carolina (510; 13 percent of total), while the greatest number was recorded in Georgia (873; 23 percent of total). The U.S. Drought Monitor released on December 3 showed 21 percent of the Northeast in an extreme, severe, or moderate drought and 33 percent as abnormally dry. Drought stress also caused leaves to change color and drop earlier than usual in parts of the Northeast. Warm and dry conditions led to drought development in California and Nevada and major drought intensification in the Four Corners states during Calendar Year 2020. Coldest highest max temperatures for April were recorded at several major climate sites including Bridgeport and Hartford, Connecticut; Boston and Worcester, Massachusetts; Newark, New Jersey; Binghamton, Islip, and Kennedy Airport, New York. The nationally averaged minimum temperature (overnight lows) during 2020 was 42.4F, 2.4F above average and also ranked sixth warmest in the 126-year record. Some reservoirs also experienced below-normal water levels. In 2020, above-average heat was more widespread than it has been in 2021 so far. The coldest temperature observed during the year was -4 degrees F (-20 degrees C), which was recorded on Mt. This . The greatest rain totals ranged from 4 to 9 inches (102 to 229 mm), with Allentown, Pennsylvania, having its wettest August day with 4.92 inches (124.97 mm) of rain. Drought conditions also dried up or reduced water supplies that some firefighters rely on to fight fires. June, July, and December also ranked among the warmest 20 percent (top 25) of history for the region. Through November 30, and the official end of the Atlantic hurricane season, several records were tied or broken. In early May, Binghamton, New York; Harrisburg, Pennsylvania; Kennedy Airport, New York; and LaGuardia Airport, New York recorded their coldest May temperature on record. The winds caused water levels to rise significantly along Lake Eries eastern shoreline, resulting in flooding near Erie, Pennsylvania, and Buffalo, New York. The highest thunderstorm wind gust recorded during the year was 84 mph (38 m/s), which was measured near Mountain Lake, VA as a squall line moved through southwestern Virginia on April 8th. Temperatures across the region for 2020 averaged 1.2 degrees F (0.7 C) above normal. Soil moisture conditions in the fall and early winter are important for the High Plains region because, as soils freeze, available moisture is locked in place until spring. The U.S. Drought Monitor released on December 31 showed four percent of the Northeast in a moderate drought and 19 percent of the region as abnormally dry. About 30 percent (1,154 of 3,843) of these reports were observed during April. Influenced by warm ocean temperatures, Kahului and Hilo experienced a record-warm year in 2020. Heavy rainfall during early December saturated vegetable fields in southern Florida, resulting in crop losses, increased disease pressure on lettuce and beans, and bloom dropping in pepper and tomato plants.
