A cold front moved across South Florida with showers and severe thunderstorms ahead of the front. One of these severe thunderstorms spawned a tornado in Boca Raton.

A tornado touched down in the Woodfield Hunt Club community of Boca Raton at 736 AM EST. Damage consisted of several uprooted trees, several large trees snapped halfway up and a tree felled into a house. Roofing was damaged from downed trees and limbs and strong winds also removed numerous Spanish tiles from many homes. Of note was a projectile in the form of a 6-12 inch diameter tree limb which punctured a roof. The tree limb was likely carried by the tornado from an adjacent neighborhood. ||The tornado lifted just west of Jog Road and touched down again on the east side of Jog Road. This segment of the tornado was rated an EF-1. Damage total is estimated.

The tornado which had initially touched down at the Woodfield Hunt Club community in West Boca touched down again in The Colonnade community, then continued on a ENE track across St. Andrews Blvd and affecting the Les Jardins community, then lifting at Patch Reef Park south of Yamato Road and west of Military Trail. ||Damage in this segment represented EF-0 magnitude and consisted mainly of roof damage, downed trees and branches and light poles (especially at Patch Reef Park). A light pole at the park fell on a city vehicle. Total damage to park was around $8,000 and included the light pole and the windshield of the city vehicle.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 05:20 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
