This page documents the tornadoes and tornado outbreaks of 1948, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes. Also, prior to 1950, tornadoes were not officially surveyed by the U.S. Weather Bureau, which would later become the National Weather Service, and thus had no official rating. All documented significant tornadoes were instead given unofficial ratings by tornado experts like Thomas P. Grazulis.

All documented significant tornadoes prior to 1950 in the United States were given unofficial ratings by tornado experts like Thomas P. Grazulis, which this article uses for the ratings below. Most of these records are limited to significant tornadoes; those rated F2 or higher on the Fujita scale, or which caused a fatality. Some events listed by Grazulis were likely tornado families rather than single tornadoes.^[2] There are also no official tornado counts for each month, so not every month is included in this article. In subsequent years, the documentation of tornadoes became much more widespread and efficient, with the average annual tornado count being around 1,253.^[3] Outside the United States, various meteorological organizations, like the European Severe Storms Laboratory rated tornadoes, which are considered official ratings.

Tornadic activity continued into the new year from the previous day. An intense tornado, with an estimated intensity of F3, struck Atlanta, Carmack, and Mantee, Mississippi, scattering furniture for miles. One person was killed in Mantee.

The tornado had an estimated strength of F2.^[1] Around the same time, a long-track tornado impacted Clermont, Brown, Clinton, and Fayette counties in Ohio. The tornado had an estimated strength of F2 as it destroyed three barns near Newtonsville and unroofed several homes along its 40 miles (64 km) path with an estimated width of 75 yards (69 m).^[1]

An F3 tornado struck Newton, Mississippi, which killed five people and injured 36 others. Thirty large and small homes were completely destroyed with debris scattered for miles and the tornado cut “a freight train into two parts”. It was noted that the path of this tornado was S-shaped or it was two tornadoes.^[1]
