A few isolated thunderstorms developed during the afternoon of March 27th, but a line of strong to severe thunderstorms moving across the northern half of Mississippi brought more intense severe weather later that evening into the early morning hours of the 28th. Tornadoes and damaging straight line winds accompanied the overnight storms.

A brief EF-0 tornado developed east of the Mississippi River levee in Rosedale near the intersection of Levee Street and Main Street. A large portion of a church���s metal roof was peeled off, and the siding and facade of the building was damaged. The tornado lofted the roofing material into the trees and carried it several blocks to the northeast. It caused some roof damage to several other homes and snapped several large hardwood branches before lifting just north of Brown Road on the east side of Rosedale. Estimated peak wind speed was 85 mph.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a tornado watch, issued at 02:01 UTC and running to 06:43 UTC.

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 Enhanced Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 01:04 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.

18 more were confirmed in the United States that day.

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.
