The record minimum temperature of -50 degrees F was observed by an automated observing station operated by the US Geological Survey (USGS) at a river gage on the Big Black River near the Canadian border. The data are archived by the USGS, and the validity of the observation was confirmed by the State Climate Extremes Committee. The value also ties observations in NH and VT for the coldest temperature recorded for the Northeast region of the United States.

The previously reported record of -69 degrees F set at Peter's Sink on Feb 1, 1985 is widely considered an accurate observation, but no information concerning the observation or the station could be identified, and the value is heavily affected by the local terrain. The -50 degrees F at Strawberry Tunnel is the coldest temperature observation that can be verified from publicly available observations at established observation stations in Utah.
Vermont -50 -46 December 30, 1933 (Bloomfield)
The -50 degrees F minimum temperature ties with values from NH and ME as the all-time coldest temperature for the Northeast region of the United States.

Although higher amounts have been observed in other states, the 32.52 inches of rainfall that was observed in 24-hrs over July 19-20, 1997 at Dauphin Island Sea Lab in conjunction with Hurricane Danny is the greatest 24-hr rainfall that has been directly observed at an officially established observation station within the coterminous United States.
Alaska 15 381 October 10, 1986 (Seward Airport)
The previously-listed state record of 15.2 inches at Angoon on October 12, 1982 was determined to be invalid by the SCEC, based largely on analysis that resulted in this Bulletin of the American Meteorological Society article.

Hourly precipitation values for Hoegee's Campground (in the mountains outside Los Angeles) indicate the greatest 24-hour rainfall occurred between 1:00 AM on January 22nd to 1:00 AM on January 23rd. During that period, the storm delivered 25.83 inches (corrected from previous reports of 26.12 inches). A detailed post-storm report was produced by the Weather Bureau.
Colorado 11 279 June 17, 1965 (Holly)
Greater amounts are known to have occurred (e.g., Ft. Collins flood of July 27-28, 1997), but never at a legitimate gauge.

The previously reported extreme of 38.70 inches at Yankeetown on September 5, 1950 is an estimated depth of rainfall calculated as part of a post-storm survey of Hurricane Easy (Cedar Keys Hurricane). Value has historically been considered reasonably accurate (and even an underestimate of actual rain fall), but as an estimate cannot be considered an official observation from a reliable precipitation gauge.
Georgia 21 533 July 6, 1994 (Americus)
Hawaii 38 965 January 24 - 25, 1956 (Kilauea 1134)
The 38.00 inches in 24-hrs at Kilauea Sugar Co. Plantation (Kauai) on January 24-25, 1956 is an estimate, but is listed as the record because it was obtained from a reliable rain gauge and is deemed conservative by an inch or more (that is, the 12-inch gauge was overflowing when it was emptied for the first time). Storm reports indicated 41.90 inches fell over period 9 AM 1/24/56 to 3 PM 1/25/56 (including 6-inches in 30 minutes and 12 inches in the first hour). The greatest accurately observed 24-hr precipitation is 31.95 inches at Honomu (Hawaii) on February 20, 1918. More information on the January 24-25, 1956 Kilauea storm rain fall can be found on page 10 of the Weather Bureau's 1961 "Climate of the States: Hawaii (Climatography of the United States No. 60-51)".

Previously reported record of 16.70 inches in Decatur Co. on August 5-6, 1959 is likely valid, but was estimated from a post-event survey observation. A 13.52 inch observation was made at Atlantic 5SW on June 14, 1998, but it is likely that the observation covered more than a 24-hr period.
Kansas 0 0 (Under Review)
The previously posted value of 13.53" was discovered to be in error. An investigation to determine the legitimate record is underway.

Oregon 11 279 November 6, 2006 (Nehalem 9 Ne)
Pennsylvania 13 330 June 22, 1972 (York 3 Ssw Pump Stn)
Arguably the greatest 24-hour rainfall on record outside of the tropics occurred around Smethport, PA on July 17, 1942. A post-event survey by the Weather Bureau provided a widely accepted maximum storm rainfall of 34.50 inches within a 12 hour period, of which an estimated 30.60 inches fell in just 6 hours. However, the greatest observed 24-hr rain fall for Pennsylvania occurred in conjunction with Hurricane Agnes in 1972.
Puerto Rico 23 584 October 7, 1985 (Toro Negro Forest)
Value was observed during the passage of Tropical Storm Isabel (October 4-8, 1985).
Rhode Island 12 305 September 16 - 17, 1932 (Westerly 1 W)
South Carolina 14 356 September 16, 1999 (Myrtle Beach)
Previously listed record of 17.00 inches at Antreville on Augst 27, 1995 (Tropical Storm Jerry) was incongruent with other observations in the area, and all reliable evidence pointed to a much smaller 24-hr value. The 14.80 inches observed at Myrtle Beach on September 16, 1999 is a result of Hurricane Floyd.
South Dakota 8 203 May 6, 2007 (Groton)
The reported value has been evaluated by the State Climate Extremes Committee. Greater amounts have fallen in 24 hours or less across SD, but have not been observed by reliable precipitation measurement gauges. Post flood survey of Black Hills flood of June 9, 1972 indicated rainfall extremes of up to 15 inches (near Keystone, SD) in 6 hours may have occurred. Again, on June 13-14, 1976 up to 10 inches of rain may have fallen over the Black Hills, while on June 14, 1996 a near-stationary thunderstorm produced an estimated 14 inches of rain between Sturgis and Hereford. Finally, on August 17, 2007 an estimated 10.5 inches of rain fell west of Hermosa.
Tennessee 13 330 September 13, 1982 (Milan Exp Stn)
Texas 42 1067 July 25 - 26, 1979 (Alvin)
The 24-hour rainfall of 42.00 inches was reported from an observer 8.5 miles west of Alvin, Texas between 7 AM July 25th and 7 AM July 26th, 1979 in conjunction with Tropical Storm Claudette. Observer reported that the 10-inch gauge was overflowing at his 1 AM reading, and so the 42 inches may be underreported by at least 3 inches. This 42.00-in rainfall exceeds any observed 24-hr precipitation value for the United States. 43.00 inches of rain in this storm is acknowledged as the United States national record 24-hr precipitation amount, but that value appears to have been estimated in a post-storm survey and is therefore not listed here.
Utah 5 127 February 1, 1963 (Deer Creek Dam)
A value of 8.40 inches was reported as part of a post-flash flood survey conducted by the National Weather Service at North Odgen on September 7-8, 1991.

Storm Data (Vol. 11, No. 8) reports associated with Hurricane Camille (August 1969) indicate "... substantiated amounts up to 31 inches ... falling mainly in Nelson and adjacent counties ...." The 14.28 inches at Williamsburg fell in conjunction with Hurricane Floyd.
Washington 14 356 November 23 - 24, 1986 (Mount Mitchell #2)
West Virginia 12 305 June 18, 1949 (Brushy Run)
It is widely accepted that the greatest precipitation in a 24 hr period for West Virginia was an estimated 19.00 inches that reportedly fell in 2 hrs and 10 minutes on July 18, 1889 at Rockport during a cloudburst that caused Tygart Creek to rise 22 feet in one hour. However, this value has not been confirmed.

Louisiana 13 33 February 13, 1960 (Colfax)
The 13.0 inches observed at Colfax on February 13, 1960 is the greatest 24-hr snowfall that could be confirmed for Louisiana. It is likely that higher 24-hr amounts fell during the Valentine's Day blizzard of February 13-15, 1895 (in which storm totals of 14 to 24 inches were prevalent from Galveston, TX to Lake Charles, LA) as well as the blizzard of December 21-22, 1929. However, all reported snow falls from these events appear to be accumulated amounts from which daily totals cannot be reliably extracted.
