Precipitation Records: Rainfall and Snowfall Extremes
Record 24-hour precipitation events by state (Data source: National Weather Service)
Precipitation records document the most extreme rainfall and snowfall events in United States history. These events often lead to significant flooding, infrastructure damage, and sometimes loss of life. The records below highlight the most extreme 24-hour precipitation events recorded at official weather stations.
Record 24-Hour Rainfall
The highest 24-hour rainfall total in U.S. history was recorded in Alvin, Texas, where 43 inches fell during Tropical Storm Claudette in July 1979. Hawaii holds the record for the most rainfall in a 24-hour period on U.S. soil, with 49.69 inches falling at Waipā Garden on Kauai on April 14-15, 2018.
Record 24-Hour Snowfall
The greatest 24-hour snowfall total in U.S. history was recorded at Silver Lake, Colorado, where 76 inches fell on April 14-15, 1921. More recently, 58 inches fell in 24 hours at Thompson Pass, Alaska on December 29, 1955. These extreme snowfall events often lead to complete shutdowns of affected areas.
| State | Record Rainfall (inches) | Date | Location | Record Snowfall (inches) | Date | Location |
| Wisconsin | 11.72 | June 24, 1946 | Mellen | 26 | December 26, 1904 | Neillsville |
| Louisiana | 22.00 | August 29, 2012 | Hackberry | 24 | February 14-15, 1895 | Rayne |
| Colorado | 11.08 | September 12, 2013 | Fort Carson | 76 | April 14-15, 1921 | Silver Lake |

Historic Extreme Weather Events
Timeline of significant extreme weather events in United States history
Beyond individual temperature and precipitation records, the United States has experienced numerous historic weather events that have shaped communities and influenced policy. These events represent the most extreme manifestations of weather patterns and often set multiple records simultaneously.
The Dust Bowl (1930s)
The 1930s Dust Bowl set numerous records for drought severity, temperature extremes, and ecological impact. July 1936 remains the hottest month on record for many Midwestern states, with temperatures exceeding 110°F for days. The drought conditions combined with poor agricultural practices created unprecedented dust storms.
Hurricane Katrina (2005)
Hurricane Katrina set multiple records including the costliest hurricane in U.S. history ($125 billion in damages), one of the strongest hurricanes to make landfall (Category 5), and causing the highest storm surge ever recorded in the United States (27.8 feet at Pass Christian, Mississippi).
Chicago Blizzard (1967)
The Chicago Blizzard of 1967 dropped a record 23 inches of snow in just 29 hours, paralyzing the city. Wind gusts reached 53 mph, creating drifts up to 15 feet high. The storm remains a benchmark for winter weather severity in the Midwest and led to significant improvements in urban snow management.
“Weather records are more than just numbers—they tell the story of our climate’s extremes and help us prepare for future events. Understanding these historical patterns is essential for building resilience in our communities.”

How to Access State Weather Records
Climate Data Online portal interface for accessing historical weather records
Historical weather records are maintained by several government agencies and academic institutions. The most comprehensive source is the National Centers for Environmental Information (NCEI), which maintains the Global Historical Climatology Network daily (GHCNd) database. Follow these steps to access official state weather records:
- Visit the Climate Data Online Search page – The official portal for accessing verified weather records across the United States.
- Select “Daily Summaries” under Weather Observation Type – This provides access to daily temperature, precipitation, and other weather measurements.
- Set your date range – Use the calendar tool to select your period of interest, from specific dates to multi-decade periods.
- Search by location – Enter a ZIP code, city, county, or state to find weather stations in your area of interest.
- Add data to your cart – Select the stations and data types you want to download (all data is free).
- Submit your request – Enter your email address to receive the data download link.
Pro Tip: For the most complete historical records, select weather stations with “First Order” or “ASOS” designations, as these have the longest and most consistent observation histories. Some stations have records dating back to the late 1800s.
State Climate Offices
Each state maintains its own climate office that often provides more detailed local records than national databases. These offices can be valuable resources for state-specific weather extremes and climate patterns that may not be fully captured in national datasets.
University Research Centers
Many universities maintain specialized climate research centers that provide access to curated weather datasets and expert analysis. These centers often offer more detailed regional analyses and specialized datasets focused on specific weather phenomena.

Frequently Asked Questions About State Weather Records
How are official weather records verified?
Official weather records undergo rigorous verification by the State Climate Extremes Committee (SCEC), which is associated with NOAA’s National Centers for Environmental Information. The committee examines the measurement equipment, calibration records, observer notes, and surrounding station data to confirm extreme values. Only after this thorough review are records officially recognized in the national database.
Why do some weather records date back to the 1800s while others are more recent?
The period of record varies significantly among weather stations. Some locations, particularly in major cities and at military installations, have continuous weather observations dating back to the late 1800s. Other stations, especially in rural areas or newer communities, may have been established much more recently. Additionally, measurement technology and standards have evolved over time, affecting the comparability of older records.
Are weather records being broken more frequently in recent years?
Analysis of the State Weather Record database shows an increasing frequency of record high temperatures compared to record low temperatures over the past several decades. While individual extreme events can occur in any year, the overall trend shows warming patterns consistent with broader climate change observations. Precipitation records show more regional variability, with some areas experiencing more extreme rainfall events while others face more severe droughts.
How can I find weather records for a specific date in history?
To find weather conditions for a specific historical date, use the Climate Data Online tool and select “Daily Summaries” as your dataset. Enter the specific date or date range you’re interested in, then search by location. This will provide observed weather conditions from nearby stations for that date. For dates before official records began in your area, historical newspaper archives often contain weather observations and can be a valuable alternative source.
