During 1999, a total of 1,339 tornadoes touched down across the United States, ranking it as the eighth-most active year since reliable records began to be kept in 1950;{{cite web|work=Storm Prediction Center|publisher=National Oceanic and Atmospheric Administration|year=2013|accessdate=June 13, 2013|title=Annual Tornado Maps|url=http://www.spc.noaa.gov/wcm/annualtornadomaps/}} at the time, 1999 was the fourth-most active year on record. The year began with the most active January on record, featuring 216 tornadoes. Culminating with the largest outbreak in the month, with over 100 tornadoes touching down on January 21 and 22 (surpassing the previous daily record of 39 on January 10, 1975), many records were broken. Due in large part to this outbreak, Arkansas saw more tornadoes in 1999 than any other year, with 107 recorded, and its most active January. The state also broke the record for most tornadoes in January of any state.{{cite web|work=National Weather Service Office in Little Rock, Arkansas|publisher=National Oceanic and Atmospheric Administration|date=May 14, 2013|accessdate=June 13, 2013|title=Making Tornado History in 1999|url=http://www.srh.noaa.gov/lzk/?n=tor1999.htm}}

The European Severe Storms Laboratory maintains a database of all severe weather events across the continent. The vast majority of tornadoes go unrated due to a lack of surveys; however, some nations, such as France, provide detailed reports on these events. Of the 87 reported tornadoes during 1999, 45 were rated.{{cite web|publisher=European Severe Storms Laboratory |year=2013 |accessdate=June 6, 2013 |title=European Severe Weather Database |url=http://www.essl.org/cgi-bin/eswd/eswd.cgi |url-status=dead |archiveurl=https://web.archive.org/web/20111228161620/http://www.essl.org/cgi-bin/eswd/eswd.cgi |archivedate=December 28, 2011 }}

Exceptional tornado activity took place across the United States in January, with 216 tornadoes touching down, more than ten times the average of 20. This set the record for most tornadoes recorded in the month, and more than quadrupled the previous record of 52 set in 1975.{{cite web|author=Keli Tarp|publisher=National Oceanic and Atmospheric Administration|date=December 27, 1999|accessdate=June 13, 2013|title=1999 tornado summary|url=http://www.norman.noaa.gov/1999/12/1999-tornado-summary/}}{{cite web|author=Keli Tarp|publisher=National Oceanic and Atmospheric Administration|date=February 9, 1999|accessdate=June 13, 2013|title=January tornado number breaks national records|url=http://www.norman.noaa.gov/1999/02/january-tornado-number-breaks-national-records/}} The extreme activity during the month was attributed to an unusually spring-like setup, with a warm, moist air mass from the Gulf of Mexico flowing northward into an area with strong upper-level westerlies. The synoptic set up of these factors was typical of March or April rather than mid-winter. January 1999 was the most active month for tornado activity in meteorological winter until it was later surpassed by December 2021, which had a total of 227 tornadoes in a similarly hyperactive month.

On January 1, a strong upper-level low moved over Southeast Texas, while an accompanying surface low formed over North Texas. A cold front extended southward from this surface low into the Gulf of Mexico. Ahead of this front, a strong low level jet formed, bringing a surge of warm, moist air from the Gulf northward. The combination of these factors resulted in an unstable environment favoring the development of rotating supercell thunderstorms.{{cite web|work=National Weather Service Office in Lake Charles, Louisiana|publisher=National Oceanic and Atmospheric Administration|date=January 10, 2010|accessdate=June 6, 2013|title=January 1-2, 1999 Historic Tornado Outbreak|url=http://www.srh.noaa.gov/lch/?n=e010299}} The sole fatality of the outbreak was from an F2 in East Texas.
