During the afternoon of Dec 15, just enough ingredients came together to support isolated severe storms ahead of a cold front. Across the Lower Mississippi River Valley, peak heating contributed to decent instability in the developing warm sector in advance of the front. Sufficient low level wind shear and strong winds aloft were also in place as a decent upper low was located to our north. This helped to support organized thunderstorm activity along with a few rotating mini-supercell storms.||A long lived, persistent, storm tracked across the southern counties (roughly a Bude to Taylorsville, Mississippi line) and produced a few funnel clouds and one instance of a brief tornado (southwest of Mize). Along the actual front, a broken line of storms developed. One cell along the line developed some weak rotation and produced a brief tornado near Bovina, Mississippi. Activity weakened during the evening as it pushed east and out of the area around midnight.

This weak tornado touched down along Tucker Road, causing minor damage to a mobile home. The tornado continued along Allen Place, snapping a few large trees and causing minor roof damage to a home. Some of these trees took down a few powerlines in the process along the path. The tornado lifted on Tiffintown Road where one tree was uprooted. The tornado was rated an EF0 with max wind speeds of 85 mph.

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 19:59 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Jackson/Brandon,MS radar (KDGX), 70 km away, was scanning. The volume nearest the touchdown began at 23:58 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.
