The Oklahoma Weather Timeline provides a decade-by-decade listing of interesting or disastrous events that have occurred in Oklahoma's weather history. For more detailed daily summaries (since 2003) please view the Oklahoma monthly climate summaries.

2020 February 6: A frigid winter day saw the Tipton Mesonet site in far southwestern Oklahoma record a temperature of 1.2 degreesthe coldest of the year and the first time in Mesonet history a site in the panhandle didnt hold that distinction.

2020 October 26-28: A strong cold front hit the state along with what was arguably the most significant October winter weather event in Oklahomas recorded history. An estimated 388,792 residents were without power after a crippling ice storm affected much of the state, damaging thousands of trees and power lines. Ice accumulations between 0.5 inches and 2.0 inches occurred across central Oklahoma, while the panhandle received a general swath of 2-5 inches of snow. Record low maximum temperatures occurred for several Mesonet sites across the event as well. Damages totaled more than $26 million.

2021 February 15th: The coldest day in Oklahomas history was observed on this day with an average statewide temperature of -.4 degrees, the first time a day was averaged below zero, and by 1:55 am the next morning, all reporting Mesonet sites were below zero.

2021 February 14th-17th: In the midst of a generational arctic blast, two winter storms dropped widespread totals of 5-15 inches of snow across the state (topping out at 17 inches in Roosevelt), with snow drifts towering several feet due to wind gusts of over 40 mph, with statewide temperatures near or below zero.

2021 February: A historic cold snap between the 7th and the 20th saw multiple rounds of wintry precipitation and record low temperatures. 96 of the 120 mesonet sites recorded their lowest temperature ever and the state was below freezing for over 200 hours, with the Lahoma site recording 334 consecutive hours below freezing. The outbreak caused millions of dollars in agricultural losses as well as 750 weather-related injuries.

2020-2021 Winter: Oklahoma City recorded 21.7 inches of snow, marking it one of the snowiest winters in recent history.

December 2021: In what could best be described as a climatological anomaly on steroids, Oklahoma soared to its warmest December on record, besting the previous mark by more than 5 degrees. It was a remarkable display of muscle by Mother Nature that saw the statewide average temperature finish more than 10 degrees above normal at 50.4 degrees, as measured by the Oklahoma Mesonet. December 1933 amd 1965 are tied for second place at 45.1 degrees.

2022 June 10: Rapid onset of heat and a pronounced lack of precipitation on this date led to flash drought, intensifying the drought already in place since August 2021. Aided by the hottest summer since 2011, 100% of the state was considered to be in at least moderate drought by the U.S. Drought Monitor by October, and 85% of the state in at least extreme drought. The drought waxed and waned through spring 2023 before finally lessening.

2022 July 19: An extremely hot day for the entire state of Oklahoma occurred as all Mesonet sites topped 100 degrees for only the 3rd time since its inception. The Mangum site tied the record for highest recorded temperature at a Mesonet site when it reached 115 degrees. This day occurred in the midst of a very warm and dry summer that saw rapid drought intensification occur by the end of the month.

2022 Summer: The June-August statewide average temperature of 82.8 degrees marked the climatological summer of 2022 as the 8th-warmest in Oklahoma since records began in 1895, and the warmest in the state since the record-hot summer of 2011.

2022 : The Oklahoma Mesonet site at Goodwell finished 2022 with 6.48 inches of rain, breaking the previous all-time lowest annual rainfall record for any location in Oklahoma of 6.53 inches from Regnier in 1956. Those data go back to the late 1880s.

2023 August 21: A miserably hot day across Oklahoma was punctuated by the Jay Mesonet site's 127-degree heat index, the all-time record for the network. Previously, the most 120+ heat index values the network had seen in a single day was three back on July 12, 2020. Eighteen sites eclipsed 120 degrees on August 21, 2023, and 12 on the previous day (Aug. 20).

2024 April: Fifty-five tornadoes touched down in Oklahoma during April 2024, besting the previous record high for the month of 54 set back in 2012. There were four deaths related to tornadoes in Oklahoma during the month.

2024 : A 1,000-year rainfall event occurred in the Panhandle on June 18-19, causing catastrophic flooding on the flat terrain of the region. Widespread totals of 6-9 inches were reported from the event that began late on the 18th and lasted through the morning of the 19th. The Goodwell Mesonet site recorded 7.67 inches of rain, with 7 inches falling in just over seven hours. A federal site near Goodwell recorded 8.64 inches, and an NWS cooperative site in Hooker measured 7.99 inches. The flooding led to road closures and impacted several homes and businesses, with some residents evacuated due to rising water levels. The magnitude of the rainfall event was also reflected in the June monthly rainfall totals, with the Guymon Municipal Airport leading the state at 10.3 inches, a rare feat for a semi-arid Panhandle station. The federal sites at Hooker and Goodwell came in second and third with 10.13 and 9.52 inches, respectively.
