Tornado outbreak sequence of December 1–6, 1953

The first six days of December 1953 produced a destructive and deadly tornado outbreak sequence across the Southern United States. There were 19 confirmed tornadoes, including a violent F4 tornado that hit the northwest side of Alexandria, Louisiana and even more violent F5 tornado that hit Vicksburg, Mississippi. In all, the tornadoes killed 49 people, injured 404 others, and caused $45,709 million (1953 USD) in damage. The death toll made this deadliest December tornado outbreak ever recorded and it would not be surpassed until 2021. This was also the last of the series of deadly and catastrophic tornado outbreaks to strike the US in 1953.

Background
1953 had already been extremely deadly tornado season due to multiple outbreaks that affected a vast majority of the country in the Spring and Early-Summer. In particular, tornadoes in Waco, Texas, Flint, Michigan, and Worcester, Massachusetts had taken 324 lives and injured thousands more. Tornado activity had slowed down heading into July, however, with no fatal tornadoes having occurred from July to November. Climatologically, however, the Southeast can routinely provide favorable conditions for tornado outbreaks in the Winter months and on December 1, 1953, a mile-wide F3 tornado southeast of Seguin, Texas kicked off six straight days of active and deadly tornado activity.

Meteorological synopsis
At least three low-pressure systems formed and moved northward over the Great Plains. Adequate moisture and wind shear on the warm side of the system allowed for repeated rounds of severe and tornadic supercells and squall lines over a six-day period. The outbreak ended as a surface anti-cyclone pushed through the region.

Fort Polk–Alexandria–Dry Prong–Tullos, Louisiana
This violent, deadly, long-track tornado was embedded within a much larger area of damaging straight-line winds, heavy rain, and a sharp temperature gradient. It followed an erratic path, devastating areas in and around Fort Polk, Alexandria, Georgetown, and Kisatchie National Forest during the early-morning hours of December 3. It first touched down in Fort Polk and caused heavy tree damage as it moved northeastward towards Alexandria. Then, the tornado moved through Lacamp and clipped the northwest side of Leander where, at peak intensity, it severely damaged four houses. Many other houses, barns, and miscelleanous buildings were damaged or destroyed as well. Seven of the nine fatalities occurred in Leander where the tornado caused $2.5 million in damages.

In Rapides Parish, the tornado caused some damage in the town of Hineston before moving back into rural areas. It proceeded into the town of Otis, clipped the northwest side of the Claiborne Range, then moved over the Kincaid Reservoir and into the western side of Alexandria. Along its northeasterly path, the tornado caused major damage in the northwestern section of Lee Heights as well as the Kingsville neighborhood where it destroyed or damaged 20 houses. The tornado then made an abrupt turn to the north-northwest (possibly occluding or reforming) and struck the Paradise community east of Tioga causing significant property damage. A trailer with four sleeping highway employees was thrown 100 yd, but all of them survived. Four buildings in the present-day town of Ball were destroyed and 43 others were damaged in the latter location. Throughout Rapides Parish, the tornado injured ten other people and caused $5 million in damage.

After entering Grant Parish and striking Pollock Municipal Airport, the tornado heavily damaged the town of Bentley. It then paralleled US-167 and struck the town of Dry Prong. From there, the tornado continued along a northeasterly track, clipping the towns of Breezy Hill and Western Lincecum and heavily damaging Mudville as it crossed over US 165. It passed through the town of Selma as well as the east side of Georgetown. Throughout Grant Parish, the tornado destroyed two houses, many barns, and other buildings, then damaged 25 other homes damaged, injured five people and caused $7.5 million in damage.

The tornado then entered La Salle Parish with catastrophic results. Severe damage occurred in a rural area before the tornado struck Tullos. Approximately 60 houses and many other buildings were damaged or destroyed, two small children were killed and 15 other people were injured. Thousands of trees were damaged in this area as well, many of which were downed or splintered, before the tornado rapidly weakened and dissipated. Damage in and around Tullos was estimated at $2.5 million.

The tornado (or tornado family) was on the ground for 85.5 mi or at least two hours and 15 minutes with a maximum width of 300 yd. It damaged mostly harvested crops and agricultural supplies in storage in addition to damaging or destroying thousands of trees. The same storm produced very severe lightning with little thunder that affected Colfax. The tornado also passed 20 mi east of a climatological substation near Winnfield, which showed a rapid rise of 5° and then a very rapid fall of 12°. High winds accompanied the tornado over an area of 20 mi, and excessive rainfall also affected the entire area. Grazulis listed the event as three separate tornadoes from different storms rather than the same storm with the F4 tornado being the last of three; he rated the other two tornadoes F2.

Madison Parish, Louisiana/Vicksburg–Waltersville, Mississippi
On December 5, a powerful and destructive tornado touched down near the small community of Delta, Louisiana in Madison Parish, the rapidly growing and strengthening tornado would then crossed the Yazoo River in Warren County, Mississippi, and struck Downtown Vicksburg, causing major devastation throughout the city. It destroyed electrical services and multiple buildings in and around downtown, ignited several fires, and totaled numerous automobiles. The tornado was officially given an F5 rating, but the rating is questionable since the tornado reportedly demolished only frail structures. Thomas P. Grazulis unofficially gave this tornado an F4 rating.

Non-tornadic effects
On December 1, severe thunderstorm winds destroyed several barns and chicken houses, damaged a house, and blew down a few trees in Huntsville, Texas. Several fronts produced strong winds throughout various regions on December 4, causing severe damage and several casualties. In Southeastern Wisconsin, one person was killed and another was injured while in Central Arizona, there were seven injuries and one death. Additionally, severe thunderstorm winds injured seven people near Clarksdale, Mississippi on December 5.

Aftermath and recovery
The F4 tornado in Louisiana temporarily knocked out power to the Alexandria area, hampering communications. At one point the twister was actually headed directly towards the downtown area, but fortunately narrowly missed it as well the VA hospital five miles north of the city. No one was injured and no property damage was reported there or in the city.

In Vicksburg, Mississippi, the F5 tornado broke the city's gas line, which remained out of service after repairs. Residents were forced to go without cooked food even as temperatures dropped to 31 F overnight on December 6.
