In addition, for the first time on record, Newark did not reach 70 degrees F (21 degrees C) during the month of April. Even as the winter started, drought conditions continued to expand, which is highly unusual for the High Plains at this time of the year. Through the end of summer, most of the Southeast region remained drought-free, except for a few short-lived pockets of moderate drought in portions of northern and coastal Virginia, Georgia, southeastern Alabama, and west-central Florida. For example, in western West Virginia, portions of two 180-foot (55 m) communications towers were knocked over, a building at a car dealership collapsed, and the roofs of several homes were damaged or destroyed. The 2020 annual precipitation totals indicate that precipitation for the year was above normal for much of the Southern Region, with Tennessee experiencing its sixth-wettest year on record while the region as a whole received an average annual precipitation total of 328.59 inches (8346.19 mm), making it the eleventh-wettest year on record. Summer was warmer and wetter than normal for most of the Southern Region. The lack of a need for supplemental drying was a benefit for farmers. Additional data received and processed after the release of this summary may result in small differences for annual values and ranks. Twenty-seven of the 30 named storms were the earliest named storm, for their respective number, on record. Farther inland, winds gusted over 50 mph (22 m/s) in northern Georgia, Upstate South Carolina, and North Carolina, resulting in widespread downed trees and power outages. These fires burned thousands of acres of forest and rangeland, caused evacuations, closed roads, and impacted air quality. Conversely, Oklahoma had the fewest tornado reports (31), Tennessee had the fewest hail reports (60), and Louisiana had the fewest wind reports (256). Plains snowpack was variable throughout the season. Preliminary reports indicate Hurricane Laura generated a storm surge over 17 feet (5.18 meters) above ground level, which would be the largest surge on record for Louisiana. Every state reported wetter than normal conditions. Severe thunderstorms in these same areas downed trees and powerlines, as well as spawned three tornadoes: an EF-1 that snapped and uprooted trees in northern Maryland, an EF-0 that destroyed several barns in northern Maryland, and an EF-0 that damaged several buildings in southeastern Pennsylvania. The region experienced temperatures 2 to 4 degrees warmer than normal in December and January. There were at least 60 injuries and 4 deaths attributed to the storm system. Below-average temperatures occurred across parts of the Southeast Interior region. For example, in New Hampshire, an emergency drought law banning outdoor fires near public woods was in effect for a month, and several communities and the White Mountains National Forest had burn bans. The severe weather season got off to a very slow start this year, with only 10 tornado watches issued nationally during May. Global Temperature Report for 2020 - Berkeley Earth The maximum wind speed was estimated at 85 mph, and three injuries were associated with the microburst. May 2021 Global Climate Report | National Centers for Environmental These six regions differ spatially from the nine climatic regions of the National Climatic Data Center. Eight of the Northeast states were drier than normal while four were wetter than normal. During a four-day period (August 16-19) 8,532 lightning strikes were detected in central and northern California that ignited 362 new fires, including the August Complex which burned 1,032,649 acres. Annual precipitation totals ranged from 12 to more than 20 inches (305 to more than 508 mm) above average in these areas. There were two months (March and November) where the entire region experienced a top-10 warmest month on record. Find out how to read the year to date and temperature/precip plots. The 2020 fire season was very active and ramped up in mid-summer and extended well into autumn. Fay made landfall near Atlantic City, New Jersey, on July 10 and dropped between 3 and 7 inches (76 to 178 mm) of rain on parts of Maryland, Delaware, eastern Pennsylvania, New Jersey, southeastern New York, and southwestern Connecticut. The center of the system moved across Iowa as just the second tropical system to do so. Flooding issues were noted especially in eastern Kentucky in February, the Ohio River flood plain in the spring but also along the Mississippi River system. England: monthly mean temperature 2022 | Statista Between 1961 and 1990, temperatures in England averaged nine degrees Celsius, and in the period of 2012 to 2021, average temperatures in the country had increased to 10.2. Moderate drought first emerged in Minnesota in early June and by the end of July had touched parts of all nine Midwest states. Add to Cart . The largest hailstones observed during the year were teacup-sized (i.e., 3-inch or 76-mm diameter), which were reported in Vernon, AL on March 29th, Darlington County, SC on May 5th, and Lake Mary, FL on May 21st. Portions of West Virginia and the Mid-Atlantic also saw freezing rain, with ice accumulations of up to 0.41 inches (10.41 mm), and sleet. The tornadoes downed trees, destroyed outbuildings, and damaged roofs and siding of some buildings. In February, five of six states experienced warmer than normal conditions (Texas was slightly cooler than normal) while all six states were wetter than normal, with Mississippi experiencing its fifth-wettest February on record while Tennessee experienced its eighth-wettest February on record. Much of the western half and eastern third of the CONUS experienced above-average maximum temperatures for the year with Arizona ranking warmest on record. 2021 Continued Earth's Warming Trend - NASA Thirteen tropical cyclones (Tropical Storm Arthur, Tropical Storm Bertha, Tropical Storm Cristobal, Tropical Storm Fay, Hurricane Isaias, Tropical Storm Kyle, Hurricane Laura, Hurricane Marco, Hurricane Sally, Tropical Storm Beta, Hurricane Delta, Hurricane Zeta, and Tropical Storm Eta) brought high winds, heavy rainfall, inland flooding, storm surge, and tornadoes to widespread portions of the Southeast region, including Puerto Rico and the U.S. Virgin Islands. Kentucky was the wettest state with 9.97 inches (253 mm) above normal which ranked as the 8th wettest in its history. 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. CERTIFIED (official) climate data is available from the National Centers for Environmental Information (NCEI). There were road closures, cars trapped in floodwaters, and water rescues. However, the drought was rapidly eliminated by beneficial rainfall from Tropical Storm Isaias at the end of July. Fires were a major issue across Colorado and Wyoming this year, with the three largest fires in Colorados history burning this summer and fall. From the beginning of January through mid-March, a pocket of moderate-to-severe drought persisted along the eastern half of the Florida Panhandle. This value will be evaluated by the State Climate Extremes Committee later in 2021 to determine if a state record for lowest mean sea level pressure will be established. After two consecutively wet years, 2020 was an extremely dry year for the majority of the High Plains region. This years snow season (2020-2021) kicked off with several early snowfalls, starting in September. The California fire season started slow but then exploded due to a rare dry thunderstorm event in mid-August. Despite Record Heat Waves, This Likely Won't Be - The Weather Channel Just a week later, on Christmas Eve and Christmas Day, a storm system dropped as much as 6 inches (152 mm) of rain on the region, with several locations having one of their 10 wettest December days on record. Burn bans were enacted in several locations. The projection suggests that 2021 is very likely to be somewhere between the fifth and seventh warmest year on record. The dryness extended to the east side of the Sierra Nevada into the Great Basin; Reno, Nevada saw its second driest year since 1938 with 2.72 in (69.09 mm, 37% of normal). In September, every state except for Louisiana and Mississippi experienced cooler than normal temperatures, while every state experienced wetter than normal conditions. The path taken by the storm system was one of the furthest to the west and north in history. Further south, Stockton, California reported its warmest year on record (in the past 72 years) at 64.8 F (18.2 C), 3.5F (1.9 C) above normal. On January 13th, a microburst damaged a school in Sampson County, NC. The only streak longer was during the first 32 weeks of 2019. Over 45 percent (77 of 168) of the long-term stations observed annual mean temperatures that were within their five warmest values on record. Storm reports noted numerous road closures, multiple water rescues, some evacuations, and a few homes taking on water. The nationally averaged maximum temperature (daytime highs) was above average for 2020 at 66.3F, 2.3F above average, ranking as sixth warmest in the 126-year record. Despite the snowfall, the fall season was dry, overall, and the majority of the region went into winter with dry soils. Red indicates places that were warmer than average, and blue indicates places that were colder than average. 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. Every state except for Texas experienced wetter than normal conditions. On November 11th and 12th, the interaction of moisture surging northward from Tropical Storm Eta and an approaching cold front produced 3 to more than 8 inches (76 to more than 203 mm) of rainfall across much of the Carolinas and Virginia. Numerous fallen trees, mudslides, and river flooding were reported in southwestern Puerto Rico, according to local emergency management officials. Rainfall totals were generally less than 3 inches (8 cm), with higher amounts in northern West Virginia, south-central Pennsylvania, and central and southern Maryland. Above-average conditions were observed across much of the North Slope, West Coast and the Aleutians, primarily due to the lack of coastal sea ice. A rare flash flood emergency was issued by the Philadelphia/Mt. 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. Harford, Connecticut, received only 4.42 inches (112.27 mm) of precipitation during summer, making it the sites driest summer on record. There were five fatalities and 65 injuries associated with this tornado, many of which occurred in the hardest hit areas just south of Estill, SC. March was an exceptionally warm month for the region, as three states (Louisiana, Mississippi, and Texas) experienced a top-5 warmest March on record, while Oklahoma experienced a top-10 warmest March on record. On the 9th, Fort Lauderdale, FL observed its third wettest November day on record, with 7.30 inches (185 mm) of precipitation. Flooding in southeastern Pennsylvania, Delaware, and portions of New Jersey and Maryland led to road closures, stranded vehicles, and water rescues. Baker City, in northeast Oregon, saw its warmest year on record going back to 1944 with an annual average temperature 48.3 F (9.1 C), 3.9 F (2.2 C) above normal. For a second year in a row the Southwest monsoon failed to produce much needed rainfall. 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. The year 2020 proved to be a warm year for the Southern Region. There were no areas of below-average annual temperatures observed across the Lower 48 during 2020. Winter was warmer and wetter than normal for most of the Southern Region, with the region experiencing its tenth-warmest winter on record. Water restrictions were in place for hundreds of locations in New England, as well as some locations in New York and Pennsylvania. Climate Extremes Index (USCEI) for 2020 was 80 percent above average and ranked as seventh highest in the 111-year record. In October, Worcester, Massachusetts, took one of its reservoirs offline due to low water levels. Hurricanes Hanna and Delta were primarily rain events, with reports of 15 inches (381 mm) in southern Texas from Hanna and 17 inches (431.80 mm) in southwestern Louisiana from Delta. With 1.1 inches (28 mm) of snow on the 25th, Asheville, NC (18692020) observed its fifth highest snowfall on Christmas Day since records began 151 years ago. These dry conditions were coupled with extreme heat, which helped fuel some of the largest wildfires in Colorados history. Only January-May of 2010 and 2016 were warmer. Other sites saw only a trace, but for Islip, New York, it made May a snowier month than February. Portland, Maine, recorded its earliest 70 degrees F (21 degrees C) day on record on March 9. California, Nevada, and the Four Corners states all received below normal precipitation with some pockets of above normal in Washington, Oregon, Idaho, and Montana. Power outages lasted five days in some locations. Climate Normals will shift from 1981-2010 to 1991-2020. Global monthly temperature anomalies, with ENSO status Allentown, Pennsylvania, had its warmest winter on record. If you have further questions or comments about the GHCN data or the Climate Data Online interface, you can send an email to NOAA NCEI at ncei.orders@noaa.gov or call them at 1-828-271-4800. Even in these areas, the wetness became a memory as drought developed and expanded in the late summer, fall, and early winter. The tornado, the first of the year in New England, snapped and uprooted trees. National Climate Report | National Centers for Environmental This switch from wet to dry was so pronounced that some locations went from having a top 10 wettest year in 2019 to a top 10 driest year in 2020. Temperatures across the region for 2020 averaged 1.2 degrees F (0.7 C) above normal. 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. This is a mere 0.12C above the 1991-2020 reference period, making it a decidedly "average" year in comparison to the climate of the recent past. The event, which qualified as a derecho, caused widespread damage, downing trees and wires, knocking out power to more than 500,000 customers, and causing four deaths. June 2021 Global Climate Report | National Centers for Environmental U.S. monthly average temperature 2023 | Statista Despite slightly above normal snowpack in the Colorado River Basin, April-July inflows into Lake Powell were only 52% of normal due a combination of above normal temperatures and evaporative demand and a lack of any substantial early summer monsoonal rainfall. The global temperature departure for February 2021 was +0.64C (+1.15F) the coolest February since 2014. In May, cooler than normal conditions prevailed across every state except Texas, while precipitation was higher than normal for every state except for Mississippi. Straight-line winds of up to 80 mph (36 m/s) caused extensive damage in several locations. Following the passage of Tropical Storm Eta in November, vegetable crops in southern Florida were severely damaged, with estimated costs ranging from $85 to as much as $320 million. Flooding and flash flooding caused fatalities in the Midwest. During June, abnormal dryness expanded to include parts of every state except New Jersey and moderate drought was introduced in parts of New England and New York. In addition, hundreds of pecan trees were uprooted across southern Alabama, with some of the losses occurring in 90-year-old orchards. Rhode Island officials noted that fires were climbing trees and were concerned that items like lawn mowers and chains could spark fires, which is a behavior more typical of western U.S. wildfires and unusual in the Northeast. Warm conditions continued into March, but, overall, spring temperatures were below normal due to cooler conditions in April and May. One of the largest fires burned over 8,600 acres in Collier County and forced a portion of I-75 to close. Northern Delaware experienced some of its worst flash flooding in at least 15 years. This ranked 2020 as the 12th warmest since 1895, and the warmest year since 2012. The highest winds, over 100 miles per hour (161 km per hour), were in central Iowa causing severe damage to crops and trees. The spatial extent of drought increased slightly from 18% at the beginning of the year to 19% at the end of the year. Portland, Maine, recorded six days this August with a high of at least 90 degrees F (32 degrees C), tying its August record. Several tropical systems affected the Northeast this year, with Tropical Storm Fay, Tropical Storm Isaias, and Tropical Storm Zeta being particularly noteworthy. Dropping to 16 degrees F (-8.9 degrees C) on December 26th, Greensboro, NC (19032020) ended its longest streak of 694 consecutive days with a daily minimum temperature at or above 20 degrees F (-6.7 degrees C), surpassing the previous record by 277 days.
