There were four months (January, March, July, and November) where all six states averaged above-normal temperatures. Peanuts in the Florida Panhandle were unable to be dug due to rainfall from Sally, and farmers noted that fungal disease and rotting would affect the quality of the harvest. Similarly, several other sites including Hartford, Kennedy Airport, and LaGuardia Airport (New York) did not reach 70 degrees F (21 degrees C) in April, tying as the least number of 70 degrees F (21 degrees C) days on record for April. Eleven of the Northeasts 35 major climate sites set or tied their record for least snowy March. Crops largely reached maturity and were harvested after drying down in the field. Fires were a major issue across Colorado and Wyoming this year, with the three largest fires in Colorados history burning this summer and fall. Freezing rain accumulations of 0.05 to as much as half of an inch (1 to as much as 13 mm) occurred in central and western portions of North Carolina, as well as southwestern, central, and northern parts of Virginia.

In 2020, above-average heat was more widespread than it has been in 2021 so far. 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. At the beginning of 2020, only 12 percent of the High Plains region was experiencing moderate to exceptional drought (D1-D4), and these conditions were largely confined to western and southern areas of Colorado and Kansas. Dry wells were reported in New York and across New England, including more than 275 wells in Maine. November 2020 Temperature Precipitation : December 2020 Temperature Precipitation January 2019 Temperature Precipitation : February 2019 Temperature Precipitation : Some cattle farmers also thinned their herds earlier than usual. 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. Twenty-five fatalities and at least 166 injuries were caused by tornadoes during the year. During August, conditions worsened in New England, with severe and moderate drought expanding and almost every part of that region experiencing some level of dryness. 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. Drought conditions also dried up or reduced water supplies that some firefighters rely on to fight fires. Elkins, West Virginia, had its snowiest May day and snowiest month of May on record, while Concord, New Hampshire, saw measurable snow in May for the first time in over 50 years. The thermometer will display "Lo" if the temperature is lower than 89.6 and "Hi" if the temperature is above 107.6, which leaves a pretty large range for a healthy temperature. Excessive rainfall, paired with high humidity, in Georgia slowed the drying down of corn, with many farmers battling whiteflies and boll rot in cotton. All state rankings are based on the period spanning 1895-2020. Annual temperature departures were above normal for nearly all of the Western U.S. The total area experiencing at least abnormally dry conditions grew from roughly one-third of the region to two-thirds of the region by the end of the year while the total area experiencing exceptional drought conditions increased. Strengthening to a hurricane, Isaias made landfall near Ocean Isle Beach, NC on August 3rd, with peak sustained winds of 85 mph (38 m/s) and a maximum wind gust of 99 mph (44 m/s) in Federal Point, NC. There were numerous closed roads, submerged vehicles, and dozens of water rescues.

In southeastern Pennsylvania, Chester Creek rose to its fourth highest water level on record, exceeding its previous fourth highest level set days earlier. Alabama, South Carolina, North Carolina, Virginia, West Virginia, Maryland and Delaware each ranked warmest on record with six additional states' minimum temperatures ranking second warmest on record. These conditions both improved and deteriorated through winter and into spring, with the total area experiencing at least abnormally dry conditions decreasing but the total area experiencing extreme drought conditions increasing, with a small area of exceptional drought conditions developing. Of this 24-hour precipitation total, Key West observed 3.95 inches (100 mm) in a single hour, which is its second highest hourly rain rate ever recorded. Storm reports noted numerous road closures, multiple water rescues, some evacuations, and a few homes taking on water. Data for 2020 should be considered preliminary. Holly National Weather Service office.

The average global land and ocean surface temperature for January 2022 was 0.89C (1.60F) above the 20th century average of 12.0C (53.6F). While agricultural and livestock production was satisfactory across much of the Southeast during the year, exceptional wetness and numerous landfalling tropical cyclones did produce some significant impacts. All but three of these 25 stations were located in North Carolina and Virginia. On the 11th, Sarasota-Bradenton, FL (19112020) observed its wettest November day on record, with 6.41 inches (163 mm) of rainfall. Unfortunately, in early June the total area experiencing at least abnormally dry conditions began to increase. Hartford, Connecticut, recorded 39 days this summer with a high of at least 90 degrees F (32 degrees C), its greatest on record for summer.

According to the U.S. Drought Monitor (USDM), drought coverage expanded throughout much of 2020 with a minimum CONUS extent of 9.6 percent occurring on February 18 and maximum coverage of approximately 50 percent on December 22. In the Desert Southwest, Roswell, New Mexico reported its warmest year on record since records began in 1949 with an annual average temperature of 64.6 F (18.1 C), 3.8 F (2.1 C) above normal. A total of 85 long-term stations across the region, with at least five located in every state, observed annual precipitation totals that were ranked within their five highest values on record. Within the year there was a slight increase in summer, another slight decrease during autumn, and finally a substantial increase during the winter. Only Junes of 2015 (fourth warmest), 2016 (second warmest), 2019 (warmest), and 2020 (third warmest) were warmer and had a global temperature departure above +0.90C (+1.62F). For instance, Sioux Falls, SD had its second wettest year on record in 2018, its wettest year in 2019, and then its sixth driest in 2020 (period of record 1893-2021).

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. The highest monthly mean air temperatures in England are typically recorded in July and August of each year. For Cecil, Montgomery, and Carroll counties, it was the first February tornado on record. This graph shows the change in global surface temperature compared to the long-term average from 1951 to 1980. A few northern Maine farmers initiated the process to allow for emergency haying and grazing on conservation reserve. Caribou and Portland, Maine, had/tied their hottest November day on record, while Burlington, Vermont, had its warmest November low temperature on record.

There were 8 fatalities from Hurricane Zeta, including in Acworth, GA where a large oak tree was uprooted and fell onto a mobile home, killing a man. Several Midwest states had record yields for corn and/or soybeans. In fact, some waterways had daily record low flows and a few, including the Aroostook River in northern Maine, recorded all-time record-low flows. 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. 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. Warm extremes in both maximum and minimum temperature across much of the U.S. in addition to wet conditions across the Southeast and dry conditions in the West contributed to this elevated USCEI value. Over 1,000 wells were affected in New Hampshire, where some well drilling contractors had a waitlist of over 100 people or a 6 to 12 week wait. Colorado saw its top three largest fires in 2020 which were not fully contained until late November or early December. The rate of warming since 1981 is more than twice as fast: 0.32 F (0.18 C) per decade. There were at least four ground fires in Vermont this year, which is atypical. Massachusetts cranberry growers reported losses. This could be concerning as spring planting gets underway. Indeed, nearly the entire Southeast region was covered with above-average annual precipitation totals, except for a few small pockets of unusual dryness in southwestern Alabama, the Big Bend region of Florida, Puerto Rico, and the U.S. Virgin Islands. Nine major climate sites had their hottest summer on record: LaGuardia Airport, New York; Harrisburg and Williamsport, Pennsylvania; Burlington, Vermont; Caribou and Portland, Maine; Bridgeport and Hartford, Connecticut; and Providence, Rhode Island. There were two months (March and November) where the entire region experienced a top-10 warmest month on record. Providence, Rhode Island, picked up 1.6 inches (4.1 cm) of snow on October 30, tying as the sites snowiest October day on record. From the beginning of January through mid-March, a pocket of moderate-to-severe drought persisted along the eastern half of the Florida Panhandle. The drought that was already in place combined with a failure of the monsoon and well above normal temperature were the primary climate enablers of fire in the Colorado River Basin this year. Across the region, there were hundreds of closed roads, stranded vehicles, water rescues, and buildings affected by flooding. Drought was largely absent across the Southeast region due to extensive periods of above-average precipitation during the year, but an episode of moderate-to-severe (D1D2) drought did impact much of Florida and coastal Alabama from spring through early summer. These areas included portions of northern New England, New York, and Pennsylvania. Winter was warmer and wetter than normal for most of the Southern Region, with the region experiencing its tenth-warmest winter on record. In fact, Philadelphia, Pennsylvania, had its fourth wettest July day on record with 4.15 inches (105.41 mm) of rain on July 10. Winter wheat was also impacted, with at least 15 percent of the crop in poor to very poor condition at the start of 2021 in Colorado (34 percent), Kansas (17 percent), and Nebraska (15 percent), according to the USDAs National Agricultural Statistics Service. Some areas of the region, especially western and southern Colorado, had departures over 2.0 degrees F (1.1 degrees C), which led to many locations ranking in the top 10 warmest years on record. On January 31st, Charlotte, NC continued its record of reporting at least a trace of snow in every winter season since 1878. Flooding and flash flooding caused fatalities in the Midwest. Above-average annual precipitation was observed from the Great Lakes and Plains to the Southeast and Mid-Atlantic regions. The average global land and ocean surface temperature for January 2021 was 0.80C (1.44F) above the 20th century average of 12.0C (53.6F). The Northeast wrapped up 2020 just barely on the dry side of normal, seeing 43.61 inches (110.77 cm) of precipitation, 98 percent of normal. During summer and fall, groundwater levels were also well below normal in many drought areas. In October, Worcester, Massachusetts, took one of its reservoirs offline due to low water levels. These economic ramifications occur for several reasons, which include higher. In addition, for the first time on record, Newark did not reach 70 degrees F (21 degrees C) during the month of April. Flooding led to road closures in portions of Maryland and Delaware. In addition, hundreds of pecan trees were uprooted across southern Alabama, with some of the losses occurring in 90-year-old orchards. Drought conditions exhibited a slightly cyclical pattern throughout the Southern Region during 2020, but conditions primarily deteriorated as the year progressed. Below-average precipitation fell across much of the West, northern Plains and parts of the Northeast. Roanoke, VA (19122020) reported 8.32 inches (211 mm) of rainfall during this event, which is its fourth wettest 3-day rainfall total for any month on record. Average daily maximum temperatures were well above average along coastal portions of the region. In addition, almost 400,000 customers lost power. In Puerto Rico, moderate drought developed in mid-May and continued to intensify and expand in coverage through the early summer. December 2019 was warmer and drier than normal (with the exception of Mississippi and Tennessee, which were slightly wetter than normal), with Oklahoma and Tennessee experiencing their tenth-warmest December on record while Louisiana experienced its eighth-driest December on record. However, the drought was rapidly eliminated by beneficial rainfall from Tropical Storm Isaias at the end of July. Hawaiis peak drought extent occurred during November with approximately 74 percent coverage. Several nights of frost and freezing temperatures during the month caused some grass damage in pastures across northern and central Florida, while low-lying areas of pastures in southern Florida sustained flooding. The combination of heavy rain, melting snow, and wet antecedent conditions led to flooding in central/eastern New York, the eastern half of Pennsylvania, and Delaware. 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. Climate Normals will shift from 1981-2010 to 1991-2020. In a break from recent years, average annual temperatures were generally above normal across the High Plains region, with widespread departures of up to 2.0 degrees F (1.1 degrees C). The extreme departures in annual mean temperatures across the region were driven primarily by exceptionally warm daily minimum temperatures, as a persistent influx of tropical moisture and cloud cover suppressed nighttime cooling during the year. Add to Cart . Non-thunderstorm wind gusts of up to 70 mph (31 m/s) were recorded in New England and on New Yorks Long Island, with reports of downed trees and wires. Caribou, ME, also had significant snow during the 2019-2020 season receiving 146 inches and ranked ninth highest for any season on record. In the HadUK-Grid observational dataset that goes back to 1884, all of the Top 10 warmest years for the UK have occurred since 2002.

Red indicates places that were warmer than average, and blue indicates places that were colder than average. Climate Extremes Index (USCEI) for 2020 was 80 percent above average and ranked as seventh highest in the 111-year record. The seven other states ranked between 13th and 26th in their respective histories. In addition, about 36,000 homes and businesses in Virginia were without power following the height of the storm. No locations reported record cold or even in the bottom ten coldest years on record. Twelve of the 35 major climate sites had their least snowy February on record. During the summer, a persistent influx of tropical moisture and high humidity across much of the Southeast increased disease pressure on crops, with white mold and fungus reported on peanuts in Georgia and Florida. Many locations had precipitation totals that ranked in the top 10 driest on record, rivaling the drought years of 2017, 2012, and the Dust Bowl. Many extremely large fires with rapid spread rates occurred this year with California, Oregon, and Colorado all having set records for the largest fires in the states history. April was primarily cooler and wetter than normal, with every state except for Louisiana and Texas experiencing cooler than normal temperatures while every state except for Oklahoma and Texas experienced wetter than normal conditions. This . For the year, there were areas in all six states that averaged between 1 to 2 degrees F (0.56 to 1.11 degrees C) above normal, while parts of Texas, Oklahoma, Louisiana, Mississippi, and Tennessee averaged 2 to 3 degrees F (1.11 to 1.67 degrees C) above normal. For further details on the weather and climate events in the Midwest, see the weekly and monthly summaries in the. Damage in the form of snapped and uprooted trees occurred to the west of the school, along with the more significant roof uplift and partial outer wall collapse of the schools gymnasium. The U.S. 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). 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. All state rankings are based on the period spanning 1895-2020. It was also just the third to make it as far north as Wisconsin. Flash flooding due to heavy rain occurred again in parts of Maryland, Delaware, southeastern Pennsylvania, and New Jersey on August 12 and 13. The most costly events of the year include: Hurricane Laura, the Western wildfires and the Midwest derecho. For the West Coast fires, the exceptionally dry winter followed by a dry and hot summer and autumn were the main climate contributing factors. Despite the snowfall, the fall season was dry, overall, and the majority of the region went into winter with dry soils. The projection suggests that 2021 is very likely to be somewhere between the fifth and seventh warmest year on record. The tornado, the first of the year in New England, snapped and uprooted trees. Report: Year: Month: Additional Resources Rankings Maps April 2023 Mar 2023 - Apr 2023 Nov 2022 - Apr 2023 May 2022 - Apr 2023 U.S. Annual Temperature Anomaly. Autumn was wetter and warmer than normal for most of the Southern Region. Temperatures were below normal in the Interior, Southcentral, and Southeast regions of Alaska. Flash flooding was reported from Delaware to New York, resulting in road closures and water rescues. Key West, FL (18712020) received 9.37 inches (238 mm) of rainfall from the storm on the 12th, which is its fifth wettest day for any month on record. More than 2.5 million customers lost power, making it one of the largest storm-related outages for two energy companies. NASA uses the period from 1951-1980 as a baseline to compare how global temperatures change over time. After making landfall near Creole, LA on October 9th, the remnants of Hurricane Delta impacted parts of the Southeast with heavy rain and flooding. Washington, D.C. (18842020), Blacksburg, VA (18932020), and Mt. Oakland, California also logged its warmest year on record dating back to 1948 at 61.3 F (16.3 C), 3.8 F (2.1 C) above normal. Significant flooding occurred, particularly in southeastern Pennsylvania where several waterways recorded their highest water levels on record. Many waterways in drought areas across the Northeast saw below-normal streamflow during summer and the first half of fall. 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. Based on NOAA's Residential Energy Demand Temperature Index (REDTI), the contiguous U.S. temperature-related energy demand for 2020 was 31 percent of average and the 7th lowest value in the 126-year period of record. Yield losses in Iowa were due to a combination of drought and damages from the derecho. Worldwide, 2016 was the warmest year on record, 2020 was the second-warmest, and 2012-2021 was the warmest decade on record since thermometer-based observations began. Ohio ranked as the 7th warmest in its history and Michigan ranked 10th. Pasture and rangeland conditions were rated very poor (the lowest level) for 70 to 90 percent of southern New England, while 10 percent of Pennsylvanias corn crop was rated very poor, making it some of the worst corn condition ratings in the country. For the individual nations, it was the second warmest .

The storms winds also downed trees and power lines. This was the sixth warmest January in the 143-year global record. Philadelphia and Washington, D.C., saw less than an inch of snow for the season for only the third time since 1885. The winds caused water levels to rise significantly along Lake Eries eastern shoreline, resulting in flooding near Erie, Pennsylvania, and Buffalo, New York. In addition, two weak (EF-0 or EF-1) tornadoes snapped trees and damaged houses in northern Maryland. The global mean temperature in 2020 is estimated to have been 1.27 C (2.29 F) above the average temperature of the late 19th century, from 1850-1900, a period often used as a pre-industrial baseline for global temperature targets.
